Call your pharmacist or your doctor and ask if this is a known side effect of the med you're on. Ask if stopping has any risks, and if not, it's a good idea to stop and see if that solves your problem. Sometimes you have to taper off some meds but unless your BP is so high you're about to drop dead from it, most BP problems depending on your age and how long the problem has existed can be fixed by changing diet and lifestyle. It's slower, but it's a cure, not just a treatment of symptoms. But I agree, you should contact your doctor and if your BP is successfully being regulated by the drug, meaning it's not the BP causing the problem, find out how to stop taking it safely and see if it fixes the problem. If it does and you still need meds, try a different med.
