Exforge (amlodipine/valsartan) and valsartan (Diovan) are both used to treat high blood pressure, but they have some key differences. Exforge is a combination medication that includes amlodipine, a calcium channel blocker (CCB), and valsartan, an angiotensin II receptor blocker (ARB). Valsartan (Diovan), on the other hand, is solely an ARB. Exforge is typically taken once a day, while valsartan can be taken once or twice a day depending on the condition being treated. Exforge is available as a generic, making it a more cost-effective option. Both medications can cause dizziness and swelling, but Exforge is more likely to cause swelling due to the amlodipine component. Additionally, Exforge is not recommended for people with liver problems, while valsartan can be used in children and comes in both tablet and liquid forms. Both medications are not safe to use during pregnancy and can raise potassium levels.
