NETLOOK 40MG 20 SOFT GELATIN CAPSULE

Severe Recalcitrant Nodular Acne Isotretinoin capsules are 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, 2 means "many" as opposed to "few or several" nodules. Because of significant adverse effects associated with its use, isotretinoin capsules should be reserved for patients with severe nodular acne who are unresponsive to conventional therapy, including systemic antibiotics. In addition, isotretinoin capsules are indicated only for those patients who are not pregnant, because isotretinoin capsules can cause life-threatening birth defects (see Boxed AND WARNINGS ). 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. 1,3,4 If a second course of therapy is needed, it should not be initiated until at least 8 weeks after completion of the first course, because experience has shown that patients may continue to improve while off isotretinoin capsules. The optimal interval before retreatment has not been defined for patients who have not completed skeletal growth (see WARNINGS: Skeletal: Bone Mineral Density , Hyperostosis , Premature Epiphyseal Closure ).

Isotretinoin capsules should be administered with a meal (see PRECAUTIONS: Information for Patients ). The recommended dosage range for isotretinoin capsules are 0.5 to 1 mg/kg/day given in two divided doses with food for 15 to 20 weeks. In studies comparing 0.1, 0.5, and 1 mg/kg/day 8 , 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 mg/kg/day, as tolerated. Failure to take isotretinoin capsules 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 capsules have 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 capsules, even in low doses, has not been studied, and is not recommended. It is important that isotretinoin capsules be given at the recommended doses for no longer than the recommended duration. The effect of long-term use of isotretinoin capsules on bone loss is unknown (see WARNINGS: Skeletal: Bone Mineral Density , Hyperostosis , and Premature Epiphyseal closure ). Contraceptive measures must be followed for any subsequent course of therapy (see PRECAUTIONS ).

Clinical Trials and Postmarketing Surveillance The listed below reflect the experience from investigational studies of isotretinoin , and the postmarketing experience. The relationship of some of these events to isotretinoin therapy is unknown. Many of the side effects and seen in patients receiving isotretinoin are similar to those described in patients taking very high doses of vitamin A (dryness of the skin and mucous membranes, e.g. of the lips, nasal passage, and eyes). Dose Relationship Cheilitis and hypertriglyceridemia are usually dose related. Most reported in clinical trials were reversible when therapy was discontinued; however, some persisted after cessation of therapy (see WARNINGS and ). Body as a Whole allergic reactions, including vasculitis, systemic hypersensitivity (see PRECAUTIONS: Hypersensitivity ), edema, fatigue, lymphadenopathy, weight loss Cardiovascular palpitation, tachycardia, vascular thrombotic disease, stroke Endocrine/Metabolic hypertriglyceridemia (see WARNINGS: Lipids ), alterations in blood sugar levels (see PRECAUTIONS: Laboratory Tests ). Gastrointestinal inflammatory bowel disease (see WARNINGS: Inflammatory Bowel Disease ), hepatitis (see WARNINGS: Hepatotoxicity ), pancreatitis (see WARNINGS: Lipids ), bleeding and inflammation of the gums, colitis, esophagitis/esophageal ulceration, ileitis, nausea, other nonspecific gastrointestinal symptoms. Hematologic allergic reactions (see PRECAUTIONS: Hypersensitivity ), anemia, thrombocytopenia, neutropenia, rare reports of agranulocytosis (see PRECAUTIONS: Information for Patients ). See PRECAUTIONS: Laboratory Tests for other hematological parameters. Musculoskeletal skeletal hyperostosis, calcification of tendons and ligaments, premature epiphyseal closure, decreases in bone mineral density (see WARNINGS: Skeletal ), musculoskeletal symptoms (sometimes severe) including back pain, myalgia, and arthralgia (see PRECAUTIONS: Information for Patients ), transient pain in the chest (see PRECAUTIONS: Information for Patients ), arthritis, tendonitis, other types of bone abnormalities, elevations of CPK/rare reports of rhabdomyolysis (see PRECAUTIONS: Laboratory Tests ).
