What Should I Do If I Miss a Dose?

If you do not take your isotretinoin as scheduled, take your missed dose as soon as you remember. If it is almost time for your next dose, skip the missed dose and continue with your regular schedule. Do not take a double dose.
 

How Does Isotretinoin Work?

Isotretinoin is a retinoid, which means that it is similar to vitamin A. It works by affecting the sebaceous glands. These glands produce sebum (an oily substance), and isotretinoin works by reducing the size of the sebaceous glands and decreasing sebum production. Isotretinoin also corrects abnormal keratinization (which causes a buildup of cells within hair follicles), a problem that contributes to acne. It is not entirely clear as to why isotretinoin causes such long-lasting, anti-acne effects.
