I was prescribed Macrobid for a suspected bladder infection. After the first dose, I was so exhausted I could barely move. My kids were with me, and I basically passed out on the couch. I felt drugged, but did not know why and couldn't rationalize that it was from the medication. So, I took my second dose--which was a big mistake. The headache can best be described as a hatchet migraine, followed by vomiting and nausea, swollen throat and dizziness. I stopped the medication two days ago. The headache and most other symptoms disappeared within 24 hours after I stopped. THE WORST MEDICATION EVER. The lab came back that I didn't even have a UTI! But now I do--thanks to Macrobid! DO NOT TAKE MACROBID. The FDA should take it off the market.
