Diovan is classified as an angiotensin II receptor blocker (ARB) that is prescribed for the following purposes: 

  • Reduce elevated blood pressure (hypertension) in adults and children aged 6 to 16. 
  • Manage heart failure in adults, potentially reducing the incidence of hospitalization stemming from this condition. 
  • Increase survival rates following a heart attack (myocardial infarction) in adults. 

Diovan works by blocking the principal pressor agent called angiotensin II, which is responsible for vasoconstriction, synthesis stimulation, aldosterone release, renal sodium reabsorption, and cardiac stimulation. 

This mechanism relaxes the blood vessels, allowing the blood to flow more smoothly and the heart to pump more efficiently. 

Uses and Dosage 

Before taking Diovan, and every time you get a refill, thoroughly review its patient information leaflet and medication guide. Consult a healthcare provider for any questions or clarifications. 

Diovan’s dosage varies per individual based on their medical condition and response to the treatment. For pediatric patients, weight is also considered. 

Typically, Diovan treatment is initiated at a low dose and titrated upwards under a healthcare provider’s supervision. It is usually administered once or twice daily, with or without food, as directed by a physician. 

For optimal efficacy, adhere to a consistent schedule when taking Diovan. To aid in medication adherence, it is recommended to take it at the same time(s) daily. 

Continue taking Diovan as directed, even if you feel well, as hypertension often presents without noticeable symptoms.

Before starting treatment with Diovan, inform your healthcare provider or pharmacist if you are allergic to it; or have any other allergies. This medication may contain inactive ingredients that can cause allergic reactions or other problems. Ask your pharmacist for more details. 

To ensure Diovan is safe for you, disclose your medical history to your doctor, especially of: 

  • Liver disease 
  • Dehydration 
  • High level of potassium in the blood 

Several products may potentially interact with Diovan, including: 

  • Aliskiren 
  • Lithium 
  • Medications that elevate serum potassium levels (such as ACE inhibitors like benazepril/lisinopril, and drospirenone-containing oral contraceptives) 

To avoid drug interactions, inform your doctor of all other medications you are taking, including prescription and non-prescription drugs, vitamins, and herbal products. 

Certain products may contain components that may exacerbate heart failure or contribute to elevated blood pressure. Consult your pharmacist regarding the safe usage of any medications or supplements, including: 

  • Cough-and-cold remedies 
  • Weight-loss aids 
  • Nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen or naproxen 

Diovan may induce dizziness, lightheadedness, or syncope upon quick transitions from a prone position, particularly during initial therapy. To mitigate this effect, gradually rise from a supine position, resting your feet on the floor for several minutes before standing. 

Combining Diovan with alcohol or marijuana (cannabis) may intensify side effects like dizziness. Until you can do so safely, avoid driving, operating machinery, or engaging in activities that require alertness. Limit your alcohol intake and discuss your marijuana (cannabis) use with your doctor. 

Inadequate fluid intake, excessive sweating, diarrhea, or vomiting can decrease blood pressure, potentially leading to lightheadedness or syncope. If these symptoms arise or persist during treatment, promptly notify your healthcare provider. 

Administration of Diovan to a pregnant woman may result in fetal harm or death, especially during the second or third trimester of pregnancy. Patients should be informed of the potential fetal hazard if this drug is used during pregnancy or if pregnancy occurs during treatment. 

Transfer of valsartan into breast milk is not well-established. Consult your doctor before breastfeeding.
