Comparing Dapsone vs Sulfamethoxazole / Trimethoprim

For Dermatitis Herpetiformis Diagnosed with D.H. in 1992, Went thru several Doctors before one figured it out. Drug has worked great without any known side affects. I discovered I needed much less than the usual prescribed 100 mg. I found that 25-50 mg did the trick for years. Now after 26 year I'm using 100 mg more regular. My DH started in the knees and elbows. A topical cream would stop it, only to pop up somewhere else on my body supposedly where the skin is "thin" .

For Dermatitis Herpetiformis I've been taking Dapsone for DH (dermatitis Herpetiformin) since 1993 through to now Aug 2018 with no issue. I did find though dapsone has a reactions with NSAID's, even things like voltaren cream. You break out in lesions and you think you've missed a tablet or got a large dose of gluten somehow, so you take more dapsone to compensate and the lesions get worse. Took a few years to work it out on my own, then google it and lots of people have found the same. Great drug but don't take NSAIDs.

For Urinary Tract Infection On this drug now and I feel awful! Was seriously considering going to ER. I have extreme nausea, tingling in my hands, dizziness, stomach pain, sore throat and my eyes are red and dry. I will never take this again for a UTI.

For Urinary Tract Infection I've been taking it for two days now, I have one more day left to take this medicine. On the first day I got a pretty strong headache and took some advil which it did react to. Second day, this morning, I woke up with a migraine, took 3 advil. after a few hours migraine then degraded to a bad headache. UTI symptoms have gotten better, headache is getting worse. I've never had a migraine before today. The last time I had a UTI I was prescribed something different, I'm not sure what but I did not suffer any side effects.
