question: My 92 yr old father has been on copro for 3 days after tearing toenail off. He is feeling dizzy,not right in his head & feels like he is going to throw up all the time. He also can t eat because of this sick feeling. Could he be having a reaction to this drug? He is in congestive heart failure also with lots of melds but this is the new drug that has been added. He s on Tramadol for pain but is taking very rarely. Any suggestions? Cipro.
