high blood pressure
"I was forced to take Losartan instead of Diovan because my insurance company refuses to pay for brand name drugs.  Really great the insurance co. would rather realize huge profits at the expense of patients' health.  Well, Losartan is terrible for me.  I had no noticeable side effects from Diovan.  But with the Losartan I've had not only hair loss but also very bad tingling down my left arm into my fingers.  My doctor just told me it's carpal tunnel syndrome without any hesitation, but I know it's the Losartan that's causing this condition because I never had it until after starting Losartan.  It also causes me to be tired and lightheaded, both side effects of this medicine."
