Trimethoprim :: Vomiting And Shaking Within 10 Minutes

My wife had a bladder infection (the second within a month) and was prescribed a 7 day course of trimethoprim. On the 7th day (having taken the last tablet) she began vomiting and shaking - within 10 minutes of this starting she become disorientated and lost her memory. She was immediately hospitalised and given a MRI scan of her brain plus various blood and urine tests but all tests proved negative. For 24 hours she suffered from extreme short term memory lose. She could not remember events that had happened just 10 seconds before hand. Very scary. I have found this web site on the second day and am relieved to see she is not alone and that the events she is experiencing are probably related to trimethoprim. 36 hours later she is still bed bound (now back at home) and has a bad headache and hot/cold sweats, neck pain and diarrhoea. Sleep seems to be the best aid but she is finding it difficult to sleep as her brain is a hive of activity trying to reconstruct the lost bits. The only drug she is now willing to take is paracetamol which helps a little. Thankfully her short term memory is now working again. How this drug has obtained a licence is a question that needs to be asked
