Hello, In a few weeks I will be redoing a bunch of tests I had done last year. I will be going to see Dr Hyde in Ottawa and he wants me to do a few tests : - Stress echo - Doppler of the carotid - Echo - Holter monitor (24 hours) I am also awaiting a date for an MRI. Those tests were initially requested by other doctors and at the time I wasn't on any meds. Now I am on nimotop 30mg twice a day. I have been since march. This medication is giving me a boost of about 30% in energy, and diminishing fatigue and other symptoms. It has an effect on blood flow to the brain. Should I stop it before doing the tests, knowing that the purpose of these tests are to find anomalies, which might be hidden entirely or in part by the effect of the medication ? And if so, how long before, knowing I will have a decrease in my health condition if I stop it and I have to drive 2 hours to get to Ottawa. I suppose I could still drive, I did before taking nimotop and I was okay. I am also taking Omega-3, NAG and Curcuma. Should I stop those too ? Thanks for your input !
