What Experts Say

Isotretinoin is a vitamin A derived retinoid that shrinks the oil glands in the skin and reduces the oily secretion that feeds acne causing bacteria. Unlike antibiotics or topical creams, it addresses the root cause of severe nodular and cystic acne, which is why many dermatologists reserve it for cases that have not responded to other standard treatments.

A typical course runs for several months and is dosed according to body weight, with most patients seeing lasting clearance long after the capsules are stopped. Regular blood tests to check liver function and lipid levels are part of standard monitoring, since the drug can temporarily raise cholesterol and triglycerides in some people.

Because isotretinoin causes severe birth defects if taken during pregnancy, doctors in Pakistan require a negative pregnancy test before starting therapy in women of childbearing age and insist on strict, continuous contraception for the full duration of treatment and for one month afterward.

Drug Interactions
