What is Byvalson?
Byvalson contains a combination of nebivolol and valsartan. Nebivolol is a beta-blocker that affects the heart and circulation (blood flow through arteries and veins).
Valsartan is an angiotensin II receptor antagonist. Valsartan keeps blood vessels from narrowing, which lowers blood pressure and improves blood flow.
Byvalson is used to treat high blood pressure (hypertension) in adults. Lowering blood pressure may lower your risk of a stroke or heart attack.
Byvalson is sometimes given together with other blood pressure medications.
Do not use Byvalson if you are pregnant. Stop using and tell your doctor right away if you become pregnant. Valsartan can cause injury or death to the unborn baby if you take the medicine during your second or third trimester.
If you have diabetes, do not use Byvalson together with any medication that contains aliskiren (Amturnide, Tekturna, Tekamlo, Valturna).

a heart condition called heart block or "AV block" (2nd or 3rd degree);
severe heart failure (that required you to be in the hospital);
severe liver disease; or
a history of slow heart beats that have caused you to faint.
If you have diabetes, do not use Byvalson together with any medication that contains aliskiren (such as Amturnide, Tekturna, Tekamlo).
You may also need to avoid taking Byvalson with aliskiren if you have kidney disease.
