Sulfamethoxazole / trimethoprim
"This medicine is working for me but it makes me feel horrible. I've been shaking, have had rapid heart rate, nausea, extremely thirsty, chills (no fever), dizziness, and cold hands and feet. I did find that taking probiotics helps. It doesn't take away everything but it helps with the nausea. The only reason I continue to take it is because the Doctor said this could be MRSA."
