Diovan 80mg (Valsartan) U

What is Valsartan 80mg? 

Valsartan 80mg is a prescription medicine used to treat high blood pressure (hypertension) and heart failure. It belongs to the Angiotensin II Receptor Blocker (ARB) drug class, which works by blocking a hormone that tightens blood vessels — allowing them to relax and making it easier for your heart to pump blood. The 80mg strength is commonly prescribed as a starting or maintenance dose, particularly for patients new to ARB therapy or those requiring a lower dose.

What is it used for?

• ✅ High blood pressure (hypertension) in adults
• ✅ Heart failure in adults who cannot tolerate ACE inhibitors
• ✅ Reducing cardiovascular risk in high-risk patients

How to take it Take one tablet once daily, at the same time each day. It can be taken with or without food. Swallow whole with a glass of water. Your doctor may adjust your dose over time — always follow your prescription instructions.

How Valsartan 80mg differs from 160mg 

Valsartan 80mg is typically the introductory or lower-range dose, often prescribed at the start of treatment or for patients who are sensitive to medication. Your doctor may later increase to 160mg depending on your blood pressure response.
