recurrence rate for tinea versicolor can be as high as 60% so this is relatively common. taking another course of the prescription drug nizoral (ketaconazole) would be the most effective. the amount of selenium in selsun blue is really not sufficient to help. please read the label since not all selsun blue labeled shampoos contain selenium. if you want to also use a topical selenium there is a prescription one that is considerably better (selenium sulfide 2. 5% lotion). other topical (many over-the-counter) antifungals will also work if you use them for 2-4 weeks.
tinea versicolor. i have had this condition my whole life i am a 35 year old male. usually a two week prescription of nizoril tablets (generic version) does the job. this time it didn't work and the condition seems to have gotten worse all over back and spreading to front of arms. should i return to the dermatologist what will they do? or should i call for another two week refill? what about selsun blue does that work?
