My doctor prescribed Ketoconazole 200Mg tablets for my Tinea Versicolor on my chest and back?

I have had T.V for years. Since I was a teenager and I’m 38. I’ve taken fluconazole several times. You take a pill and then go sweat. And i mean SWEAT!! Like take the pill and then in a couple of hours go sit your ass in a sweat lodge for a few hours. And then just sit there and marinate in your juices until you dry- and then sit a little longer: the more time you process the medication in your system through your skin and then it sits there the better. Best results ive had were two pills spaced out a week apart. But even that only lasted a few years. It always comes back. It itches and it’s annoying af

I use an OTC called NIZORAL (Ketoconazole)--get it at Walmart--which is sold as a antidandruff shampoo. I use it as a whole body wash... check it out on wikipedia... No sense taking it orally... Use it all over everyday and you will see wonders... I've suffered thru years of this problem... Sulfur and Salisylic acid are old school... Check it out ...

Tinea versicolor is a long-term (chronic) fungal infection of the skin.
Oral ketoconazole is often prescribed but usually only for 10 days at a time. This dosage often has to be repeated throughout the year.
Have you had the infection for sometime? If so maybe your doctor wants to ensure that you get rid of it.
