Isotretinoin for 1 month only? Read that it's only effective if taken for several months.

Question

I'm 50 and have suffered with acne all my life. Although it is somewhat under control now, I still get cystic acne (about 1 a month). I also have blackheads on my nose and some are larger and stubborn - they'll sometimes turn into zits but just never go away. My derm suggest I try isotretinoin for 1 month (30mg) but I've read that it's only effective if taken for several months. Any thoughts on taking isotretinoin for only 30 days? Thanks.

Accutane is a go-to medication for patients with recalcitrant cystic acne. It can reduce pore size and also reduce sebum production in your skin, making it less oily; and in turn, dryer. Accutane can be used to control acne, but patients receiving the medication should be carefully monitored. In terms of skincare, always wear an appropriate sunscreen and reduce direct sun exposure. In my patients, I recommend a good ceramide moisturizer such as Elevase whenever they are on Accutane. This will keep the skin hydrated and reduce the oiliness of the skin that is associated with oil-based moisturizers.

Hi!
Isotretinoin (accutane) is a fantastic medication for acne. Dosing-wise, it is all about the total cumulative amount of medication you take over a period of months. More than likely, a longer course would be needed to provide complete, lasting clearance. A shorter course would likely lead to incomplete clearance, and not provide lasting results. The actual day to day dose is determined based on your body weight and side effects. 
That said, there are many options out there- please consult with a board-certified dermatologist to discuss the many treatments we have available nowadays!

Thank you for your question. Isotretinoin is a weight based medication, and a certain amount needs to be taken for therapy to be effective long term. Acne recurrence is high because there is no cure for acne, and not completing the entire course of isotretinoin increases the risks for acne to return. I highly recommend you consult with your dermatologist regarding your questions and concerns about therapy. Take care and good luck.
