Sulfamethoxazole / trimethoprim
"I have used this medicine. For a stap bacterial infection. Normally 9 years ago it would work rapidly and in 10 days  it would be completely gone. But it has come back several times through the years. Now with this last infection I'm having to take double the dose, every 12 hours and I notice it is been hard it to get rid of. I'm hoping I won't get this skin boil again because I'm afraid of the antibiotics are not working  100%. What other options are there to take? But the bactrim is been my saver, til now"
