What is Isotretinoin Copyfarm?
Isotretinoin Copyfarm is used to treat severe, disfiguring nodular acne. It should be used only after other acne medicines have been tried and have failed to help the acne. Isotretinoin Copyfarm may also be used to treat other skin diseases as determined by your doctor.
Isotretinoin Copyfarm must not be used to treat women who are able to bear children unless other forms of treatment have been tried first and have failed. Isotretinoin Copyfarm must not be taken during pregnancy because it causes birth defects in humans. If you are able to bear children, it is very important that you read, understand, and follow the pregnancy warnings for Isotretinoin Copyfarm.
Isotretinoin Copyfarm is available only under a registered distribution program called the iPLEDGE™ program.
Once a medicine has been approved for marketing for a certain use, experience may show that it is also useful for other medical problems. Although these uses are not included in product labeling, Isotretinoin Copyfarm is used in certain patients with the following medical conditions:
- Folliculitis, gram-negative (bacterial infection of the skin on the face beginning near the nose).
- Hidradenitis suppurativa (sweat gland problem).
- Rosacea (red skin disorder of the face, usually of the nose and cheeks).
- Thickened or patchy skin disorders, such as keratosis follicularis, palmoplantar keratoderma, lamellar ichthyosis, or pityriasis rubra pilaris.
Isotretinoin Copyfarm indications
Severe Recalcitrant Nodular Acne
Isotretinoin Copyfarm (isotret (isotret (Isotretinoin Copyfarm capsules) inoin capsules) inoin 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. "Severe," by definition, means "many" as opposed to "few or several" nodules. Because of significant adverse effects associated with its use. Isotretinoin Copyfarm (isotret (isotret (Isotretinoin Copyfarm capsules) inoin capsules) inoin capsules) should be reserved for patients with severe nodular acne who are unresponsive to conventional therapy, including systemic antibiotics.

Isotretinoin Copyfarm description
Isotretinoin Copyfarm is a medication used for the treatment of severe acne. It is sometimes used in prevention of certain skin cancers. It is a retinoid, meaning it derives from vitamin A and is found in small quantities naturally in the body. Isotretinoin Copyfarm binds to and activates nuclear retinoic acid receptors (RAR), thereby regulating cell proliferation and differentiation. This agent also exhibits immunomodulatory and anti-inflammatory responses and inhibits ornithine decarboxylase, thereby decreasing polyamine synthesis and keratinization.
Isotretinoin Copyfarm dosage
Isotretinoin Copyfarm (Isotretinoin Copyfarm) should be administered with a meal.
The recommended dosage range for Isotretinoin Copyfarm (Isotretinoin Copyfarm) is 0.5 to 1.0 mg/kg/day given in two divided doses with food for 15 to 20 weeks. In studies comparing 0.1, 0.5, and 1.0 mg/kg/day, it was found that all dosages provided initial clearing of disease, but there was a greater need for retreatment with the lower dosages. During treatment, the dose may be adjusted according to response of the disease and/or the appearance of clinical side effects — some of which may be dose related. Adult patients whose disease is very severe with scarring or is primarily manifested on the trunk may require dose adjustments up to 2.0 mg/kg/day, as tolerated. Failure to take Isotretinoin Copyfarm (Isotretinoin Copyfarm) with food will significantly decrease absorption. Before upward dose adjustments are made, the patients should be questioned about their compliance with food instructions.
The safety of once daily dosing with Isotretinoin Copyfarm (Isotretinoin Copyfarm) has not been established. Once daily dosing is not recommended.
If the total nodule count has been reduced by more than 70% prior to completing 15 to 20 weeks of treatment, the drug may be discontinued. After a period of 2 months or more off therapy, and if warranted by persistent or recurring severe nodular acne, a second course of therapy may be initiated. The optimal interval before retreatment has not been defined for patients who have not completed skeletal growth. Long-term use of Isotretinoin Copyfarm (Isotretinoin Copyfarm), even in low doses, has not been studied, and is not recommended. It is important that Isotretinoin Copyfarm (Isotretinoin Copyfarm) be given at the recommended doses for no longer than the recommended duration. The effect of long-term use of Isotretinoin Copyfarm on bone loss is unknown.
Contraceptive measures must be followed for any subsequent course of therapy.

Isotretinoin Copyfarm interactions
See also:
What other drugs will affect Isotretinoin Copyfarm?
- Vitamin A: Because of the relationship of Isotretinoin Copyfarm (Isotretinoin Copyfarm) to vitamin A, patients should be advised against taking vitamin supplements containing vitamin A to avoid additive toxic effects.
- Tetracyclines: Concomitant treatment with Isotretinoin Copyfarm (Isotretinoin Copyfarm) and tetracyclines should be avoided because Isotretinoin Copyfarm (Isotretinoin Copyfarm) use has been associated with a number of cases of pseudotumor cerebri (benign intracranial hypertension), some of which involved concomitant use of tetracyclines.
- Micro-dosed Progesterone Preparations: Micro-dosed progesterone preparations (“minipills” that do not contain an estrogen) may be an inadequate method of contraception during Isotretinoin Copyfarm (Isotretinoin Copyfarm) therapy. Although other hormonal contraceptives are highly effective, there have been reports of pregnancy from female patients who have used combined oral contraceptives, as well as transdermal patch/injectable/implantable/vaginal ring hormonal birth control products. These reports are more frequent for female patients who use only a single method of contraception. It is not known if hormonal contraceptives differ in their effectiveness when used with Isotretinoin Copyfarm (Isotretinoin Copyfarm). Therefore, it is critically important for female patients of childbearing potential to select and commit to use 2 forms of effective contraception simultaneously, at least 1 of which must be a primary form.
- Norethindrone/ethinyl estradiol: In a study of 31 premenopausal female patients with severe recalcitrant nodular acne receiving OrthoNovum® 7/7/7 Tablets as an oral contraceptive agent, Isotretinoin Copyfarm (Isotretinoin Copyfarm) at the recommended dose of 1 mg/kg/day, did not induce clinically relevant changes in the pharmacokinetics of ethinyl estradiol and norethindrone and in the serum levels of progesterone, follicle-stimulating hormone (FSH) and luteinizing hormone (LH). Prescribers are advised to consult the package insert of medication administered concomitantly with hormonal contraceptives, since some medications may decrease the effectiveness of these birth control products.
- St. John's Wort: Isotretinoin Copyfarm (Isotretinoin Copyfarm) use is associated with depression in some patients. Patients should be prospectively cautioned not to self-medicate with the herbal supplement St. John's Wort because a possible interaction has been suggested with hormonal contraceptives based on reports of breakthrough bleeding on oral contraceptives shortly after starting St. John's Wort. Pregnancies have been reported by users of combined hormonal contraceptives who also used some form of St. John's Wort.
- Phenytoin: Isotretinoin Copyfarm (Isotretinoin Copyfarm) has not been shown to alter the pharmacokinetics of phenytoin in a study in seven healthy volunteers. These results are consistent with the in vitro finding that neither Isotretinoin Copyfarm nor its metabolites induce or inhibit the activity of the CYP 2C9 human hepatic P450 enzyme. Phenytoin is known to cause osteomalacia. No formal clinical studies have been conducted to assess if there is an interactive effect on bone loss between phenytoin and Isotretinoin Copyfarm (Isotretinoin Copyfarm). Therefore, caution should be exercised when using these drugs together.
- Systemic Corticosteroids: Systemic corticosteroids are known to cause osteoporosis. No formal clinical studies have been conducted to assess if there is an interactive effect on bone loss between systemic corticosteroids and Isotretinoin Copyfarm (Isotretinoin Copyfarm). Therefore, caution should be exercised when using these drugs together.
Laboratory Tests
- Pregnancy Test
- Female patients of childbearing potential must have had two negative urine or serum pregnancy tests with a sensitivity of at least 25 mIU/mL before receiving the initial Isotretinoin Copyfarm (Isotretinoin Copyfarm) prescription. The first test (a screening test) is obtained by the prescriber when the decision is made to pursue qualification of the patient for Isotretinoin Copyfarm (Isotretinoin Copyfarm). 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.
- For patients with regular menstrual cycles, the second pregnancy test must be done during the first 5 days of the menstrual period immediately preceding the beginning of Isotretinoin Copyfarm (Isotretinoin Copyfarm) therapy and after the patient has used 2 forms of contraception for 1 month.
- For patients with amenorrhea, irregular cycles, or using a contraceptive method that precludes withdrawal bleeding, the second pregnancy test must be done immediately preceding the beginning of Isotretinoin Copyfarm (Isotretinoin Copyfarm) therapy and after the patient has used 2 forms of contraception for 1 month.
- Each month of therapy, patients must have a negative result from a urine or serum pregnancy test. A pregnancy test must be repeated each month, in a CLIA-certified laboratory, prior to the female patient receiving each prescription.
- Lipids: Pretreatment and follow-up blood lipids should be obtained under fasting conditions. After consumption of alcohol, at least 36 hours should elapse before these determinations are made. It is recommended that these tests be performed at weekly or biweekly intervals until the lipid response to Isotretinoin Copyfarm (Isotretinoin Copyfarm) is established. The incidence of hypertriglyceridemia is 1 patient in 4 on Isotretinoin Copyfarm therapy.
- Liver Function Tests: Since elevations of liver enzymes have been observed during clinical trials, and hepatitis has been reported, pretreatment and follow-up liver function tests should be performed at weekly or biweekly intervals until the response to Isotretinoin Copyfarm has been established.
- Glucose: Some patients receiving Isotretinoin Copyfarm (Isotretinoin Copyfarm) have experienced problems in the control of their blood sugar. In addition, new cases of diabetes have been diagnosed during Isotretinoin Copyfarm (Isotretinoin Copyfarm) therapy, although no causal relationship has been established.
- CPK: Some patients undergoing vigorous physical activity while on Isotretinoin Copyfarm (Isotretinoin Copyfarm) therapy have experienced elevated CPK levels; however, the clinical significance is unknown. There have been rare postmarketing reports of rhabdomyolysis, some associated with strenuous physical activity. In a clinical trial of 217 pediatric patients (12 to 17 years) with severe recalcitrant nodular acne, transient elevations in CPK were observed in 12% of patients, including those undergoing strenuous physical activity in association with reported musculoskeletal adverse events such as back pain, arthralgia, limb injury, or muscle sprain. In these patients, approximately half of the CPK elevations returned to normal within 2 weeks and half returned to normal within 4 weeks. No cases of rhabdomyolysis were reported in this trial.

Isotretinoin Copyfarm contraindications
See also:
What is the most important information I should know about Isotretinoin Copyfarm?
Hypersensitivity to Isotretinoin Copyfarm. Hepatic or renal insufficiency. Hypervitaminosis A. Patients with excessively elevated blood lipid values.
Blood donation by patients during and within 1 month of Isotretinoin Copyfarm treatment to women of childbearing potential should be avoided.
Use in pregnancy & lactation: Isotretinoin Copyfarm is highly teratogenic. It is therefore contraindicated in women who are pregnant or who may become pregnant while undergoing treatment. There is an extremely high risk that a deformed infant will result if pregnancy occurs while taking Isotretinoin Copyfarm un any amount even for short periods. Potentially all exposed fetuses can be affected. Major human fetal abonormalities related to Isotretinoin Copyfarm administration have documented, including hydrocephalus, microcephalus, abnormalities of the external ear (micropinna, small or absent external auditory canals), microphthalmia, cardiovascular abnormalities and cerebellar malformation.
As Isotretinoin Copyfarm is highly lipophilic, the passage of the drug in human milk is very likely. Because of the potential for adverse effects, the used of Isotretinoin Copyfarm should be avoided by nursing mothers.
It is recommended that the patient use 2 forms of effective contraception to prevent pregnancy, during treatment and for 1 month after discontinuation of treatment. Testing serve to reming the patient of the importance of avoiding pregnancy. If pregnancy occurs, patient should be counseled on whether to continue the pregnancy. Isotretinoin Copyfarm therapy starts only on the second day or third day of the next normal period.
