I was prescribed Sulfameth for a sinus infection. After the 3rd pill, I started noticing my hands shaking. I wasn't immediately alarmed, but after an hour or so, I noticed my legs and head shaking as well. I began getting highly anxious and light headed. None of these were listed as side effects for the drug, and neither my doctor's office nor pharmacist could substantiate that this was because of the medication. Had it not been for this site, I might have thought I was losing it. I stopped taking the Sulfameth, and now feel fine.
