Why is this medication prescribed?  

Isotretinoin is used to treat severe recalcitrant nodular acne (a certain type of severe acne) that has not been helped by other treatments, such as antibiotics. Isotretinoin is in a class of medications called retinoids. It works by slowing the production of certain natural substances that can cause pimples to form.

How should this medicine be used?  

Isotretinoin comes as a capsule to take by mouth. Isotretinoin is usually taken twice a day with meals. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take isotretinoin exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Swallow the capsules whole with a full glass of liquid. Do not chew or suck on the capsules.

Your doctor will probably start you on an average dose of isotretinoin and increase or decrease your dose depending on how well you respond to the medication and the side effects you experience. Follow these directions carefully and ask your doctor or pharmacist if you are not sure how much isotretinoin you should take.

It may take several weeks or longer for you to feel the full benefit of isotretinoin. Your acne may get worse during the beginning of your treatment with isotretinoin. This is normal and does not mean that the medication is not working.
