Bactrim and agitation

This is my 3rd day on Bactrim. The side effects are horrible. I am taking 1 pill 2x per day for an ear infection. I am experiencing extreme fatigue, gastrointestinal upset, agitation and insomnia. I don't know how much longer I can put up with these side effects. I feel like staying in bed all day and just taking a shower and getting dressed makes me exhausted. I am 23 years old and thought I was really sick, so I ran a search on Bactrim. I would not recommend this drug to people. Ask your doctor for something else instead. The side effects with this drug are pretty bad.

I am a 38 yo female. Took bactrim for UTI. Two and half days into treatment, I could not sleep. Strange dreams, agitation. Next day, absolute feeling of panic, anxiety, restlessness, loss of appetite, weakness in hands, confusion, sweating, heavy heartbeat. Went to ER, they were unfamiliar with this reaction. Seems to take quite awhile to get the medication out of your system. I will never take bactrim again.
