Boxed Warning
ABSORICA/ABSORICA LD can cause life-threatening birth defects and is contraindicated in pregnancy. There is an extremely high risk that life-threatening birth defects will result if pregnancy occurs while taking any amount of ABSORICA/ABSORICA LD even for short periods of time. Potentially any fetus exposed during pregnancy can be affected. There are no accurate means of determining prenatally whether an exposed fetus has been affected. If pregnancy occurs, discontinue ABSORICA/ABSORICA LD immediately and refer the patient to an Obstetrician- Gynecologist experienced in reproductive toxicity for further evaluation and counseling [see Contraindications (4), Warnings and Precautions (5.1), and Use in Specific Populations (8.1)]. Because of the risk of embryo-fetal toxicity, ABSORICA and ABSORICA LD are available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called the iPLEDGE REMS [see Warnings and Precautions (5.2)].
Indications and Usage
ABSORICA and ABSORICA LD are indicated for the treatment of severe recalcitrant nodular acne in non-pregnant patients 12 years of age and older with multiple inflammatory nodules with a diameter of 5 mm or greater. Because of significant adverse reactions associated with its use, ABSORICA and ABSORICA LD are reserved for patients with severe nodular acne who are unresponsive to conventional therapy, including systemic antibiotics. Limitations of Use If a second course of ABSORICA/ABSORICA LD treatment is needed, it is not recommended before a 2-month waiting period because the patient’s acne may continue to improve following a 15 to 20-week course of treatment[see Dosage and Administration (2.2) ].
Contraindications
ABSORICA/ABSORICA LD is contraindicated in: Pregnancy [see Warnings and Precautions ( 5.1 ) and Use in Specific Populations ( 8.1 )]. Patients with hypersensitivity to isotretinoin (or Vitamin A, given the chemical similarity to isotretinoin) or to any of its components (anaphylaxis and other allergic reactions have occurred) [see Warnings and Precautions ( 5.14 )].
Adverse Reactions
The following adverse reactions with ABSORICA/ABSORICA LD or other isotretinoin capsule products are described in more detail in other sections of the labeling: Embryo-Fetal Toxicity [see Warnings and Precautions ( 5.1 )] Psychiatric Disorders [see Warnings and Precautions ( 5.4 )] Intracranial Hypertension (Pseudotumor Cerebri) [see Warnings and Precautions ( 5.5 )] Serious Skin Reactions [see Warnings and Precautions ( 5.6 )] Pancreatitis [see Warnings and Precautions ( 5.7 )] Lipid Abnormalities [see Warnings and Precautions ( 5.8 )] Hearing Impairment [see Warnings and Precautions ( 5.9 )] Hepatotoxicity [see Warnings and Precautions ( 5.10 )] Inflammatory Bowel Disease [see Warnings and Precautions ( 5.11 )] Musculoskeletal Abnormalities [see Warnings and Precautions ( 5.12 )] Ocular Abnormalities [see Warnings and Precautions ( 5.13 )] Hypersensitivity Reactions [see Warnings and Precautions ( 5.14 )] The following adverse reactions associated with the use of isotretinoin capsules were identified in clinical trials or postmarketing reports. Because some of these reactions were reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Dose Relationship Cheilitis and hypertriglyceridemia were dose related. Body as a Whole Fatigue, irritability, pain, allergic reactions, systemic hypersensitivity, edema, lymphadenopathy, weight loss. Cardiovascular Vascular thrombotic disease, stroke, palpitation, tachycardia. Endocrine/Metabolism and Nutritional Decreased appetite, weight fluctuation, alterations in blood sugar. Gastrointestinal Dry lips, chapped lips, cheilitis, nausea, constipation, diarrhea, abdominal pain, vomiting, inflammatory bowel disease, hepatitis, pancreatitis, bleeding and inflammation of the gums, colitis, esophagitis, esophageal ulceration, ileitis. Hematologic Anemia and decreased RBC parameters, thrombocytopenia, increased platelet
Mechanism of Action
The exact mechanism of action of ABSORICA/ABSORICA LD in the treatment of severe recalcitrant nodular acne in non-pregnant patients 12 years of age and older with multiple inflammatory nodules with a diameter of 5 mm or greater who are unresponsive to conventional therapy, including systemic antibiotics is unknown. ABSORICA/ABSORICA LD is a retinoid, which inhibits sebaceous gland function and keratinization. Clinical improvement in nodular acne patients occurs in association with a reduction in sebum secretion. The decrease in sebum secretion is temporary and reflects a reduction in sebaceous gland size and an inhibition of sebaceous gland differentiation.
Overdosage
Isotretinoin overdosage has been associated with vomiting, facial flushing, cheilosis, abdominal pain, headache, dizziness, and ataxia. These symptoms quickly resolved without apparent residual effects. Evaluate patients who can become pregnant who present with an ABSORICA/ABSORICA LD overdosage for pregnancy. Because an overdosage would be expected to result in higher levels of isotretinoin in semen than found during a normal treatment course, instruct male patients treated with ABSORICA/ABSORICA LD to use a condom, or avoid reproductive sexual activity with a patient who is or might become pregnant, for 1 month after the overdose. Instruct all patients with ABSORICA/ABSORICA LD overdose to not donate blood for at least 1 month. If an overdose occurs, consider contacting the Poison Help line (1-800-222-1222) or a medical toxicologist for additional overdose management recommendations.
