My acne cleared in the first few weeks. It's been 3 months, can I stop taking it early? What are the chances it comes back?

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.

Hello! 
I am glad that Accutane is working so quickly for you.  It is a fantastic medicine, but as you know it does carry some pretty annoying side effects.
Regarding your question, studies have shown that achieving a cumulative dose of 100-120 mg/kg seems to give the highest chance of prolonged improvement.  It is unlikely you achieved that in 3 months.  
If the side effects are particularly annoying, sometimes decreasing the dose can be helpful. 
Naturally, that does require a longer course of treatment.  
Hope that helps!
