CLARAVIS™ (isotretinoin capsules USP)
- Is accutane and claravis the same
Using this medicine while you are pregnant can cause very serious birth defects. Use two forms of effective birth control to keep from getting pregnant 1 month before beginning treatment, while you are using this medicine even if the medicine is temporarily stopped , and for at least 1 month after you stop taking the medicine. The most effective forms of birth control are hormone birth control pills, patches, shots, vaginal rings, or implants, an IUD, or a vasectomy for men.
One of these forms of birth control should be combined with a condom, a diaphragm, or a cervical cap. Isotretinoin must not be taken by women of reproductive age who may become pregnant unless 2 effective forms of birth control have been used for at least 1 month before the start of treatment. Contraception must be continued during the period of treatment, which is up to 20 weeks, and for 1 month after isotretinoin is stopped.
Be sure that you have discussed this information with your doctor. If you are a woman who is able to have children, you must have 2 pregnancy tests before beginning treatment with isotretinoin to make sure you are not pregnant.
The second pregnancy test must be taken at least 19 days after the first test and during the first 5 days of the menstrual period immediately before beginning treatment. In addition, you must have a pregnancy test each month while you are using this medicine and 1 month after treatment is completed. Do not take vitamin A or any vitamin supplement containing vitamin A while using this medicine, unless otherwise directed by your doctor. To do so may increase the chance of side effects.
During the first 3 weeks you are taking isotretinoin, your skin may become irritated. Also, your acne may seem to get worse before it gets better. Check with your doctor if your skin condition does not improve within 1 to 2 months after starting this medicine or at any time your skin irritation becomes severe. Full improvement continues after you stop using isotretinoin and may take up to 6 months. Your doctor can help you choose the right skin products to reduce skin dryness and irritation.
You or your child should not donate blood to a blood bank while using isotretinoin or for 30 days after you stop using it. This is to prevent a pregnant patient from receiving blood that contains the medicine. In some patients, isotretinoin may cause a decrease in night vision.
This problem may occur suddenly. If it does occur, do not drive or do anything else that could be dangerous until you know how this medicine affects you. Also, check with your doctor. Isotretinoin may cause dryness of the eyes.
If you or your child wear contact lenses, your eyes may be more sensitive to them during the time you are using isotretinoin and for up to 2 weeks after stopping it.
To help relieve dryness of the eyes, check with your doctor about using a lubricating solution, such as artificial tears. If eye inflammation occurs, check with your doctor right away.
Isotretinoin may cause dryness of the mouth and nose. For temporary relief of mouth dryness, use sugarless candy or gum, melt bits of ice in your mouth, or use a saliva substitute. However, if dry mouth continues for more than 2 weeks, check with your medical doctor or dentist. Continuing dryness of the mouth may increase the chance of dental disease, including tooth decay, gum disease, and fungus infections.
Avoid overexposing your skin to sunlight, wind, or cold weather. Your skin will be more prone to sunburn, dryness, or irritation, especially during the first 2 or 3 weeks of treatment. However, you or your child should not stop using this medicine unless the skin irritation becomes too severe. Do not use a sunlamp or tanning beds. To help isotretinoin to work properly, use sunscreen or sunblock lotions with a sun protection factor SPF of at least 15 on a regular basis.
Also, wear protective clothing and hats. Isotretinoin may cause some people to be agitated, irritable, or display other abnormal behaviors. It may also cause some people to have suicidal thoughts and tendencies or to become more depressed. If you, your child, or your caregiver notice any of these side effects, check with you doctor right away.
This medicine may increase pressure in your head, which may lead to vision loss or serious brain problems. Check with your doctor right away if you have a bad headache, blurred vision, dizziness, nausea, vomiting, or seizures. Serious skin reactions can occur with this medicine.
Check with your doctor right away if you or your child have any of the following symptoms while using this medicine: blistering, peeling, or loosening of the skin, chills, diarrhea, itching, joint or muscle pain, rash, red skin lesions, often with a purple center, sores, ulcers, or white spots in the mouth or on the lips, or unusual tiredness or weakness.
Isotretinoin may cause bone or muscle problems, including joint pain, muscle pain or stiffness, or difficulty moving. You may get hurt more easily during rough sports. You may also heal more slowly. If this medicine is for your child, tell the doctor if you think your child is not growing properly. It is very important that you or your child not use wax epilation to remove hair while you are taking isotretinoin and for 6 months after stopping it.
Isotretinoin can increase your chance of scarring from wax epilation. It is very important that you or your child not have any cosmetic procedures to smooth your skin eg, dermabrasion, laser while you are using isotretinoin and for 6 months after stopping it.
Isotretinoin can increase your chance of scarring from these procedures. This medicine may affect blood sugar levels. In vitro studies indicate that the primary P isoforms involved in isotretinoin metabolism are 2C8, 2C9, 3A4, and 2B6. Isotretinoin and its metabolites are further metabolized into conjugates, which are then excreted in urine and feces. Following oral administration of an 80 mg dose of 14 C-isotretinoin as a liquid suspension, 14 C-activity in blood declined with a half-life of 90 hours.
After both single and multiple doses, the observed accumulation ratios of isotretinoin ranged from 0. In both age groups, 4- oxo -isotretinoin was the major metabolite; tretinoin and 4- oxo -tretinoin were also observed. The dose-normalized pharmacokinetic parameters for isotretinoin following single and multiple doses are summarized in Table 3 for pediatric patients.
There were no statistically significant differences in the pharmacokinetics of isotretinoin between pediatric and adult patients. The accumulation ratios of isotretinoin ranged from 0. Claravis isotretinoin capsules is indicated for the treatment of severe recalcitrant nodular acne.
Nodules are inflammatory lesions with a diameter of 5 mm or greater. The nodules may become suppurative or hemorrhagic. Because of significant adverse effects associated with its use, Claravis should be reserved for patients with severe nodular acne who are unresponsive to conventional therapy, including systemic antibiotics.
A single course of therapy for 15 to 20 weeks has been shown to result in complete and prolonged remission of disease in many patients. Pregnancy: Category X. Prescribers should be alert to the warning signs of psychiatric disorders to guide patients to receive the help they need. Therefore, prior to initiation of Claravis therapy, patients and family members should be asked about any history of psychiatric disorder, and at each visit during therapy patients should be assessed for symptoms of depression, mood disturbance, psychosis, or aggression to determine if further evaluation may be necessary.
Patients should stop Claravis and the patient or a family member should promptly contact their prescriber if the patient develops depression, mood disturbance, psychosis, or aggression, without waiting until the next visit. Discontinuation of Claravis therapy may be insufficient; further evaluation may be necessary. While such monitoring may be helpful, it may not detect all patients at risk.
Patients may report mental health problems or family history of psychiatric disorders. A referral to a mental health professional may be necessary. The physician should consider whether Claravis therapy is appropriate in this setting; for some patients the risks may outweigh the benefits of Claravis therapy. Claravis use has been associated with a number of cases of pseudotumor cerebri benign intracranial hypertension , some of which involved concomitant use of tetracyclines.
Concomitant treatment with tetracyclines should therefore be avoided. Early signs and symptoms of pseudotumor cerebri include papilledema, headache, nausea and vomiting, and visual disturbances. There have been post-marketing reports of erythema multiforme and severe skin reactions [e. These events may be serious and result in death, life-threatening events, hospitalization, or disability. Patients should be monitored closely for severe skin reactions, and discontinuation of Claravis should be considered if warranted.
Acute pancreatitis has been reported in patients with either elevated or normal serum triglyceride levels. In rare instances, fatal hemorrhagic pancreatitis has been reported. Claravis should be stopped if hypertriglyceridemia cannot be controlled at an acceptable level or if symptoms of pancreatitis occur.
In clinical trials, the effects on triglycerides, HDL, and cholesterol were reversible upon cessation of Claravis therapy. Some patients have been able to reverse triglyceride elevation by reduction in weight, restriction of dietary fat and alcohol, and reduction in dose while continuing Claravis. Blood lipid determinations should be performed before Claravis is given and then at intervals until the lipid response to Claravis is established, which usually occurs within 4 weeks.
Impaired hearing has been reported in patients taking Claravis; in some cases, the hearing impairment has been reported to persist after therapy has been discontinued. Mechanism s and causality for this event have not been established. Clinical hepatitis considered to be possibly or probably related to Claravis therapy has been reported. If normalization does not readily occur or if hepatitis is suspected during treatment with Claravis, the drug should be discontinued and the etiology further investigated.
Claravis has been associated with inflammatory bowel disease including regional ileitis in patients without a prior history of intestinal disorders. In some instances, symptoms have been reported to persist after Claravis treatment has been stopped. Effects of multiple courses of Claravis on the developing musculoskeletal system are unknown. There is some evidence that long-term, high-dose, or multiple courses of therapy with isotretinoin have more of an effect than a single course of therapy on the musculoskeletal system.
Sixteen 7. Nine patients 4. Twenty-one Follow-up studies performed in eight of the patients with decreased bone mineral density for up to 11 months thereafter demonstrated increasing bone density in five patients at the lumbar spine, while the other three patients had lumbar spine bone density measurements below baseline values.
Total hip bone mineral densities remained below baseline range —1. In a separate open-label extension study of ten patients, ages 13 to 18 years, who started a second course of Claravis 4 months after the first course, two patients showed a decrease in mean lumbar spine bone mineral density up to 3. Spontaneous reports of osteoporosis, osteopenia, bone fractures, and delayed healing of bone fractures have been seen in the Claravis population.
While causality to Claravis has not been established, an effect cannot be ruled out. Longer term effects have not been studied. It is important that Claravis be given at the recommended doses for no longer than the recommended duration. A high prevalence of skeletal hyperostosis was noted in clinical trials for disorders of keratinization with a mean dose of 2. Additionally, skeletal hyperostosis was noted in six of eight patients in a prospective study of disorders of keratinization. The skeletal effects of multiple Claravis treatment courses for acne are unknown.
Hyperostosis may require a longer time frame to appear. The clinical course and significance remain unknown. There are spontaneous reports of premature epiphyseal closure in acne patients receiving recommended doses of Claravis. The effect of multiple courses of Claravis on epiphyseal closure is unknown. Visual problems should be carefully monitored. Corneal opacities have occurred in patients receiving Claravis for acne and more frequently when higher drug dosages were used in patients with disorders of keratinization.
Decreased night vision has been reported during Claravis therapy and in some instances the event has persisted after therapy was discontinued. Because the onset in some patients was sudden, patients should be advised of this potential problem and warned to be cautious when driving or operating any vehicle at night.
These include:. To prescribe isotretinoin, the prescriber must be enrolled and activated with the pregnancy risk management program iPLEDGE.
Prescribers can enroll by signing and returning the completed enrollment form. Prescribers can only activate their enrollment by affirming that they meet requirements and will comply with all iPLEDGE requirements by attesting to the following points:. Isotretinoin must only be prescribed to patients who are known not to be pregnant as confirmed by a negative CLIA-certified laboratory conducted pregnancy test. Meeting the requirements for a patient who can become pregnant signifies that the patient:.
If the patient has unprotected sexual contact with a partner that could result in pregnancy at any time one month before, during, or one month after therapy, the patient must:.
Any birth control method can fail. These reports are more frequent for patients who use only a single form of contraception. Therefore, it is critically important that patients who can become pregnant use two effective forms of contraception simultaneously.
Patients must receive warnings about the importance of choosing one primary method and a secondary method of contraception and that the patient must be compliant in use as outlined in the Guide for Patients who can get Pregnant.
Using two forms of contraception simultaneously substantially reduces the chances that a patient will become pregnant over the risk of pregnancy with either form alone.
Although hormonal contraceptives are highly effective, prescribers are advised to consult the package insert of any medication administered concomitantly with hormonal contraceptives, since some medications may decrease the effectiveness of these birth control products. Patients should be prospectively cautioned not to self-medicate with the herbal supplement St. John's Wort. Pregnancies have been reported by users of combined hormonal contraceptives who also used some form of St.
If a pregnancy does occur during isotretinoin treatment, isotretinoin must be discontinued immediately. The patient should be referred to an Obstetrician-Gynecologist experienced in reproductive toxicity for further evaluation and counseling. Isotretinoin is contraindicated in patients who are pregnant.
To receive isotretinoin all patients must meet all of the following conditions:. In addition to the requirements for all patients described above, patients who can become pregnant must meet the following conditions:. To dispense isotretinoin, pharmacies must be enrolled and activated with the pregnancy risk management program iPLEDGE.
The Responsible Site Pharmacist must enroll the pharmacy by signing and returning the completed Pharmacy Enrollment Form.
After enrolling, the Responsible Site Pharmacist can only activate the pharmacy enrollment by affirming that they meet requirements and will comply with all iPLEDGE requirements by attesting to the following points:. A Claravis Medication Guide must be given to the patient each time Claravis is dispensed, as required by law. This Claravis Medication Guide is an important part of the risk management program for the patients.
Only FDA-approved isotretinoin products must be distributed, prescribed, dispensed, and used. Patients must obtain Claravis prescriptions only at US licensed pharmacies. Although an effect of Claravis on bone loss is not established, physicians should use caution when prescribing Claravis to patients with a genetic predisposition for age-related osteoporosis, a history of childhood osteoporosis conditions, osteomalacia, or other disorders of bone metabolism.
Patients may be at increased risk when participating in sports with repetitive impact where the risks of spondylolisthesis with and without pars fractures and hip growth plate injuries in early and late adolescence are known. While causality to Claravis has not been established, an effect must not be ruled out. Anaphylactic reactions and other allergic reactions have been reported.
Cutaneous allergic reactions and serious cases of allergic vasculitis, often with purpura bruises and red patches of the extremities and extracutaneous involvement including renal have been reported. Severe allergic reaction necessitates discontinuation of therapy and appropriate medical management. The first test a screening test is obtained by the prescriber when the decision is made to pursue qualification of the patient for Claravis.
The second pregnancy test a confirmation test must be done in a CLIA-certified laboratory. The interval between the two tests must be at least 19 days. A pregnancy test must be repeated each month, in a CLIA-certified laboratory, prior to the patient who can become pregnant receiving each prescription.
The incidence of adrenal medullary hyperplasia was also increased at the higher dosage in both sexes. The relatively high level of spontaneous pheochromocytomas occurring in the male Fischer rat makes it an equivocal model for study of this tumor; therefore, the relevance of this tumor to the human population is uncertain.
The Ames test was conducted with isotretinoin in two laboratories. The results of the tests in one laboratory were negative while in the second laboratory a weakly positive response less than 1.
No dose response effect was seen and all other strains were negative. Additionally, other tests designed to assess genotoxicity Chinese hamster cell assay, mouse micronucleus test, S. In general, there was microscopic evidence for appreciable depression of spermatogenesis but some sperm were observed in all testes examined and in no instance were completely atrophic tubules seen.
In studies of 66 men, 30 of whom were patients with nodular acne under treatment with oral isotretinoin, no significant changes were noted in the count or motility of spermatozoa in the ejaculate. In a study of 50 men ages 17 to 32 years receiving Claravis therapy for nodular acne, no significant effects were seen on ejaculate volume, sperm count, total sperm motility, morphology or seminal plasma fructose.
It is not known whether this drug is excreted in human milk. Because of the potential for adverse effects, nursing mothers should not receive Claravis. The use of isotretinoin in pediatric patients less than 12 years of age has not been studied.
Total hip bone mineral densities remained below baseline range In a separate open-label extension study of ten patients, ages 13 to 18 years, who started a second course of isotretinoin 4 months after the first course, two patients showed a decrease in mean lumbar spine bone mineral density up to 3.
Clinical studies of isotretinoin did not include sufficient numbers of subjects aged 65 years and over to determine whether they respond differently from younger subjects. The adverse reactions listed below reflect the experience from investigational studies of Claravis, and the postmarketing experience. The relationship of some of these events to Claravis therapy is unknown.
Many of the side effects and adverse reactions seen in patients receiving Claravis are similar to those described in patients taking very high doses of vitamin A dryness of the skin and mucous membranes, e.
Cheilitis and hypertriglyceridemia are usually dose related. Neurological pseudotumor cerebri see WARNINGS, Pseudotumor Cerebri , dizziness, drowsiness, headache, insomnia, lethargy, malaise, nervousness, paresthesias, seizures, stroke, syncope, weakness.
Of the patients reporting depression, some reported that the depression subsided with discontinuation of therapy and recurred with reinstitution of therapy. Respiratory bronchospasms with or without a history of asthma , respiratory infection, voice alteration.
In humans, overdosage has been associated with vomiting, facial flushing, cheilosis, abdominal pain, headache, dizziness, and ataxia. These symptoms quickly resolve without apparent residual effects. Patients who can become pregnant who present with isotretinoin overdose must be evaluated for pregnancy. Educational materials for such patients can be obtained by calling the manufacturer.
Because an overdose would be expected to result in higher levels of isotretinoin in semen than found during a normal treatment course, male patients should use a condom, or avoid reproductive sexual activity with a patient who is or might become pregnant, for one month after the overdose.
All patients with isotretinoin overdose should not donate blood for at least one month. Isotretinoin is a potentially dangerous prescription medicine that should only be taken under the close supervision of your healthcare professional and pharmacist. If you are pregnant or may get pregnant, isotretinoin can cause birth defects, miscarriage, premature births, and death in babies.
Buying this product over the Internet bypasses important procedures to ensure that patients can take this drug safely. When these procedures are ignored, isotretinoin can cause serious and harmful side effects. Patients taking isotretinoin may experience side effects including bad headaches, blurred vision, dizziness, nausea, vomiting, seizures, stroke, diarrhea, and muscle weakness.

There is an extremely high risk that life-threatening birth defects will result if pregnancy occurs while taking Claravis in any amount, even for short periods of time. Potentially any fetus exposed during pregnancy can be affected. There are no accurate means of determining whether an exposed fetus has been affected. Birth defects which have been documented following isotretinoin exposure include abnormalities of the face, eyes, ears, skull, central nervous system, cardiovascular system, and thymus and parathyroid glands.
Cases of IQ scores less than 85 with or without other abnormalities have been reported. There is an increased risk of spontaneous abortion, and premature births have been reported.
Documented external abnormalities include: skull abnormality; ear abnormalities including anotia, micropinna, small or absent external auditory canals ; eye abnormalities including microphthalmia ; facial dysmorphia; cleft palate.
Documented internal abnormalities include: CNS abnormalities including cerebral abnormalities, cerebellar malformation, hydrocephalus, microcephaly, cranial nerve deficit ; cardiovascular abnormalities; thymus gland abnormality; parathyroid hormone deficiency.
In some cases death has occurred with certain of the abnormalities previously noted. If pregnancy does occur during treatment of a patient who is taking Claravis, Claravis must be discontinued immediately and the patient should be referred to an Obstetrician-Gynecologist experienced in reproductive toxicity for further evaluation and counseling.
Because of isotretinoin's teratogenicity and to minimize fetal exposure, Claravis is approved for marketing only under a special restricted distribution program approved by the Food and Drug Administration. Patients Who Can Become Pregnant. Patients Who Cannot Become Pregnant. Chemically, isotretinoin is cis -retinoic acid and is related to both retinoic acid and retinol vitamin A. It is a yellow to orange crystalline powder. The structural formula is:.
C 20 H 28 O 2 Molecular Weight: Each capsule contains the following inactive ingredients: butylated hydroxyanisole, edetate disodium, gelatin, hydrogenated vegetable oil, polysorbate 80, soybean oil, titanium dioxide, white wax beeswaxand vitamin E. The 20 mg capsule contains black iron oxide, red iron oxide and yellow iron oxide. The 30 mg capsule contains red iron oxide and yellow iron oxide. Isotretinoin is a retinoid, which when administered in pharmacologic dosages of 0.
The exact mechanism of action of isotretinoin is unknown. Clinical improvement in nodular acne patients occurs in association with a reduction in sebum secretion. The decrease in sebum secretion is temporary and is related to the dose and duration of treatment with Claravis, and reflects a reduction in sebaceous gland size and an inhibition of sebaceous gland differentiation. Due to its high lipophilicity, oral absorption of isotretinoin is enhanced when given with a high-fat meal.
In a crossover study, 74 healthy adult subjects received a single 80 mg oral dose 2 x 40 mg capsules of Claravis under fasted and fed conditions. Both peak plasma concentration C max and the total exposure AUC of isotretinoin were more than doubled following a standardized high-fat meal when compared with Claravis given under fasted conditions see Table 2.
The observed elimination half-life was unchanged. This lack of change in half-life suggests that food increases the bioavailability of isotretinoin without altering its disposition. The time to peak concentration T max was also increased with food and may be related to a longer absorption phase. Clinical studies have shown that there is no difference in the pharmacokinetics of isotretinoin between patients with nodular acne and healthy subjects with normal skin.
Claravis 2 x 40 mg Capsules. Following oral administration of isotretinoin, at least three metabolites have been identified in human plasma: 4- oxo -isotretinoin, retinoic acid tretinoinand 4- oxo -retinoic acid 4- oxo -tretinoin. Retinoic acid and cis -retinoic acid are geometric isomers and show reversible interconversion. The administration of one isomer will give rise to the other.
Isotretinoin is also irreversibly oxidized to 4- oxo -isotretinoin, which forms its geometric isomer 4- oxo -tretinoin. After a single 80 mg oral dose of isotretinoin to 74 healthy adult subjects, concurrent administration of food increased the extent of formation of all metabolites in plasma when compared to the extent of formation under fasted conditions.
All of these metabolites possess retinoid activity that is in some in vitro models more than that of the parent isotretinoin. However, the clinical significance of these models is unknown. In vitro studies indicate that the primary P isoforms involved in isotretinoin metabolism are 2C8, 2C9, 3A4, and 2B6. Isotretinoin and its metabolites are further metabolized into conjugates, which are then excreted in urine and feces.
Following oral administration of an 80 mg dose of 14 C-isotretinoin as a liquid suspension, 14 C-activity in blood declined with a half-life of 90 hours.
After both single and multiple doses, the observed accumulation ratios of isotretinoin ranged from 0. In both age groups, 4- oxo -isotretinoin was the major metabolite; tretinoin and 4- oxo -tretinoin were also observed. The dose-normalized pharmacokinetic parameters for isotretinoin following single and multiple doses are summarized in Table 3 for pediatric patients.
There were no statistically significant differences in the pharmacokinetics of isotretinoin between pediatric and adult patients. The accumulation ratios of isotretinoin ranged from 0. Claravis isotretinoin capsules is indicated for the treatment of severe recalcitrant nodular acne. Nodules are inflammatory lesions with a diameter of 5 mm or greater.

Acute pancreatitis has been reported in patients with either elevated or normal serum triglyceride levels. In rare instances, fatal hemorrhagic pancreatitis has been reported. Claravis should be stopped if hypertriglyceridemia cannot be controlled at an acceptable level or if symptoms of pancreatitis occur.
In clinical trials, the effects on triglycerides, HDL, and cholesterol were reversible upon cessation of Claravis therapy. Some patients have been able to reverse triglyceride elevation by reduction in weight, restriction of dietary fat and alcohol, and reduction in dose while continuing Claravis. Blood lipid determinations should be performed before Claravis is given and then at intervals until the lipid response to Claravis is established, which usually occurs within 4 weeks.
Impaired hearing has been reported in patients taking Claravis; in some cases, the hearing impairment has been reported to persist after therapy has been discontinued. Mechanism s and causality for this event have not been established. Clinical hepatitis considered to be possibly or probably related to Claravis therapy has been reported. If normalization does not readily occur or if hepatitis is suspected during treatment with Claravis, the drug should be discontinued and the etiology further investigated.
Claravis has been associated with inflammatory bowel disease including regional ileitis in patients without a prior history of intestinal disorders.
In some instances, symptoms have been reported to persist after Claravis treatment has been stopped. Effects of multiple courses of Claravis on the developing musculoskeletal system are unknown. There is some evidence that long-term, high-dose, or multiple courses of therapy with isotretinoin have more of an effect than a single course of therapy on the musculoskeletal system.

Visual problems should be carefully monitored.
localhost › GoodRx Health › Health Conditions › Acne. Absorica (isotretinoin) and Claravis (isotretinoin capsules) are retinoids, a form of vitamin A, used to treat a severe form of acne called nodular acne. localhost › GoodRx Health › Health Conditions › Acne. How to use Claravis ; Read the Medication ; Swallow capsules whole. Do not crush or chew them. Isotretinoin is usually taken twice daily for weeks, or as. If you have severe acne and have tried several treatments, your provider may have recommended isotretinoin. The first pregnancy test should be done when my doctor decides to prescribe isotretinoin. A single course of therapy for Claravis is around 15—20 weeks. Nodules are inflammatory lesions with a diameter of 5 mm or greater. Because of this, you or your child may bleed or get infections more easily.Isotretinoin is a prescription medication used to treat severe recalcitrant nodular acne. While isotretinoin is beneficial for some patients, there are risks associated with this drug. Specifically, isotretinoin is highly teratogenic i. It provides a centralized system for prescribers, pharmacies, and patients to manage patient risk, regardless of which isotretinoin product is being used. All patients treated with isotretinoin should be observed closely for symptoms of depression or suicidal thoughts, such as sad mood, irritability, acting on dangerous impulses, anger, loss of pleasure or interest in social or sports activities, sleeping too much or too little, changes in weight or appetite, school or work performance going down, or trouble concentrating, or for mood disturbance, psychosis, or aggression.
