Cozaar Adverse Event Reviews

Thu, 31 Mar 2011

I have taken Cozaar for 8 years, never had a problem. My dose was 100 mg at night and 50 mg in morning. Suddenly out of the blue my blood pressure spiked to 185/135 and my heart went into a continuous fibrilation that lasted 2 hours. I felt dizzy and faint and sick tomy stomach. I went to emergency room but everything checked out ok. My pressure was high and has stayed higher than usual for a week. I still feel a little dizzy and my heart flutters occassionaly. Wonder if anyone else has had this experience after taking Cozaar for a length of time?

I don't want to say my side-effects are from Cozaar alone, but I do feel a little different. I also take Metoprolol for my high blood. Anyway, I can't walk normally anymore. I'm a Carpenter by trade and that makes it 10 's harder. I walk with a limp. Never did until I got on these drugs. My legs feel so tired at the end of the day. And they're weak feeling. But mostly painfull and tired. I've noticed my left leg is basically, (I hate to say it), getting thinner than my right. My hands feel funny, (it's a project to open a bottle of soda), or cut my fingernails. I was never like this until I started going to Doctors. I don't know you tell me, if anyone's interested. Please!!!SOMEBODY! my email is : auxpolice at optonline.net. Thank you
