Hi,
Accutane can cause initial flares but this is usually related to the starting dose ie. a higher starting dose tend to have a higher risks of flares initially.
Personally, I start my patients on a lower dose for the 1st month and adjust accordingly subsequently.
As what Dr Colin has mentioned, I will definitely advise to cease any topicals that can cause additional irritation such as Benzoyl peroxide, astringents, acid based products etc.
If you are still having flares, consult your doctor and discuss whether you need to adjust your dose, add in some antibiotics or a short course of oral steroids to help with the flare.
Nonetheless, Accutane is an effective treatment for acne though it may take up to 3 - 4 months to see results, so I would not write it off as yet.
All the best!
