My husband has to be on Diovan for high blood pressure. He takes a 160 mg tablet once or twice a day. If his blood pressure should rise due to something he has eaten or stress, a Diovan tablet definitely does help to bring it down.
My husband does not like prescription drugs. I'm not crazy about them either. But sometimes a prescription drug is the only way to take care of a life-threatening health problem. Every drug has side effects. My husband doesn't seem to be experiencing any side effects that he can detect, but with being a diabetic, there are days when he does not feel well. Who's to say it couldn't be a side effect from the drug, as well as diabetes.
Anyway, my husband and I both have decided that we are going to try to control his blood pressure with exercise and diet so that he doesn't need to rely on drugs so much. In the meantime, Diovan does seem to be helping him to keep his blood pressure under control.
