Compare Procardia XL vs. Diovan

Head-to-head comparisons of medication uses, side effects, warnings, and more.

Key takeaways

Nifedipine ER (Procardia XL) and valsartan (Diovan) are both used to treat high blood pressure, but they belong to different medication classes and work in different ways. Nifedipine ER is a calcium channel blocker (CCB) that relaxes blood vessels to lower blood pressure and treat chest pain. It is available as an extended-release tablet taken once daily. Common side effects include swelling in the legs, dizziness, and headaches. Valsartan, on the other hand, is an angiotensin II receptor blocker (ARB) that lowers blood pressure by blocking a hormone that tightens blood vessels. It is available as a tablet and liquid, typically taken once or twice a day. Valsartan can cause dizziness and fatigue, and it is not safe to use during pregnancy. While both medications are available in lower-cost generic forms.
