Smra 0 Posted March 11, 2012 (edited) Can anyone tell me what the normal dosage of keflex is for acne, and if it should be taken once or twice a day? I am currently on 250 mg twice a day but am wondering if 500 mg once a day would work better? Edited March 11, 2012 by Smra Quote Share this post Link to post Share on other sites
