Metronidazole
"I was prescribed this medicine at 500 milligrams twice daily. At first my infection seem to get better the pain decreased. I noticed some shortness of breath within the first couple of days by the third and fourth day taking this medication I had muscle aches over my entire body, joint pain, would wake up in the middle of the night with a severe dry mouth, headaches and a bad rash that was extremely itchy and benadryl would not relieve. Now on my fifth day I have decided to discontinue this product because the muscle pain and itching or for worse than the infection is treating. I believe this is possibly a good medication however I believe maybe I should have been given smaller dose."
