Prescribed Bactrim for MRSA skin infection on my arm that I picked up at my local gym. Day 1 OK, Day 2 severe headache at the base of my skull. Day 3 continued headache, general nausea, gas. Day 4 I began to develop a low grade fever and dizziness. Almost passed out after walking just a half mile. Still a severe headache, weakness. Day 5 Headache, consistent fever of 103, chills and muscle aches, light hives visible, weakness, unable to sleep. Day 6 early am, couldn't sleep all night, went to the ER with the worst muscle aches and fever I have ever had. Hives now very clear and pronounced all over my torso. I was tested for the flu. Said it was not, but was a viral infection that was attacking my muscles. Muscle breakdown found in both blood and urine samples. ER physician changed medication to Clindamycin HCL. Told to stop Bactrim, but thought what I had was viral, not a reaction to the Bactrim. I continues to feel bad for a couple more days, but hives started to reduce, fever diminished and started to feel halfway human after being off Bactrim for a couple of days. Still not 100%. New med has it's issues too (have to take every 6 hours, can't lay down after taking it) and a nasty taste in mouth and stomach upset, loose stool. After 5 days of new med went back to my doctor. A secondary infection had set up in the Staph area. The fungal infection needed a different med. Now is 4 weeks later, after finishing all meds, still have an infection. Blood cultures taken to see if the infection is the staph or fungal. I have lost 8lb, have no taste buds, loose stool, severe stomach cramps/burning (now taking Activia to put back good bacteria in my stomach...no one told me to do this before!!). If Staph not gone, need IV antibiotic for a month. I am 50 year old female, but note I had taken this in my 30's without any problems. You can develop an allergic reaction to medicines previously OK for you. Beware of Bactrim. It kicked my behind!
Been on Bactrim in February after a stay at the hospital for what they thought was a heart attack, only to find out it was a panic attack. Developed a pimple and maroon color skin on the back of my neck a few weeks later, they put me on Bactrim, was sicker than anything, now I have a low grade fever,, 6 discs in my neck messed up, no one has a clue. My husband had MRSA from a epidural and had to have surgery on his spinal cord, the antibotic IV that HE was given, caused a blood clot and more MRSA.......be careful, this Pic line, that they would possibly put in you, goes from your arm to your heart.... We are in Ft. Myers, Florida........you don't want to get sick down here. You and I are the same age.
