How Long Does It Take to See Results from Spironolactone?

It will take at least 4 weeks to start seeing the results, it is no magic that in 1 or 2 days will improve. However, even if you don't see a big difference, don't quit your medication unless a dermatologist indicates to do it. Spironolactone is indicated when we determine that an hormonal influence is one of the 4 factors that contributes to acne.  

I have found spironolactone to be reliably effective in treating hormonal acne.  It typically takes 2 months to see results from spironolactone; you may see continued improvement for a few months after that. 

For any acne medication of any kind, you will start seeing changes at about one month in. This is why many people become frustrated and think meds aren't working. You have to give them enough time to actually make changes within the skin - which takes a minimum of a month. For a medication to be a generic form of a branded medication, it needs to be essentially the same; however, there will be some very minor differences, which is what differentiates one from the other. Usually the differences aren't noticeable and don't affect efficacy, but some people may claim so.
