This medication is used to treat severe cystic acne (also known as nodular acne) that has not responded to other treatment (e.g., benzoyl peroxide or clindamycin applied to the skin or tetracycline or minocycline taken by mouth). It belongs to a class of drugs known as retinoids. It works by decreasing facial oil (sebum) production. High amounts of sebum can lead to severe acne. If left untreated, severe acne may cause permanent scarring.
How to use Isotretinoin Capsule
Read the Medication Guide provided by your pharmacist before you start using isotretinoin and each time you get a refill. Read and sign a Patient Information/Informed Consent form before you start taking this medication. If you have any questions about isotretinoin, consult your doctor or pharmacist before taking the medication.
Swallow capsules whole. Do not crush or chew them. Isotretinoin is usually taken twice daily for 15-20 weeks, or as directed by your doctor. Directions for most generic forms of isotretinoin state that it should be taken with meals. However, the FDA has indicated that the Absorica brand may be taken with or without food. Food helps increase absorption of this drug into your bloodstream. Ask your doctor or pharmacist for more information. Take this drug with a full glass of water, and do not lie down for at least 10 minutes after taking it.
The dosage is based on your medical condition, weight, and response to treatment.
Your acne may worsen during the first few days of taking this drug, and it may take up to 1-2 months before you notice the full benefit of this medication. If severe acne returns, a second course of treatment may be started after you have stopped taking the drug for 2 months. The manufacturer does not recommend long-term use of isotretinoin. Do not take more than the recommended dose.

To relieve dry mouth, suck on (sugarless) hard candy or ice chips, chew (sugarless) gum, drink water, or use a saliva substitute.
