Hai everyone!
I was diagnosed to have acne vulgaris type 2. My physician advised me to take ISOTROIN 20 mg capsules for a month along with Clindamycin gel to apply over acne. He also told me that I must me on treatment at least for 4 - 5 months for complete suppression of acne. Is it necessary to have such a long duration of treatment? Is my condition that worse?

Why would you trust the opinion of anonymous people on the internet who have almost no medical training, let alone dermatological training, over that of your trained doctor?

Yes it is that necessary. Yes your condition is that bad. I know this because that is what your highly trained professional said.
