What is Diovan?

Diovan is a medication used by adults and children aged 1 year and over, either on its own or in combination with other medicines, to treat high blood pressure. Diovan is also prescribed to older adults for the treatment of a heart condition (a condition where the heart isn't able to pump blood enough throughout the entire body) and also to increase the chance of surviving the event of a heart attack. Diovan is a member of a class of drugs known as angiotensin II receptor antagonists. Valsartan is a drug that blocks the actions of a few natural substances that enlarge blood vessels, which allows for blood flow to move more easily as well as the heart to pump faster.


Do not take Diovan while you are expecting. Stop taking this medication and inform your doctor immediately if you find yourself pregnant. If you suffer from diabetes, avoid taking Diovan together with any other medicine that contains an ingredient called aliskiren (a blood pressure medication). You might also have to stay clear of taking Diovan with an aliskiren in the event that you suffer from kidney problems.

In rare instances, Diovan could cause an illness that causes the destruction of skeletal muscle tissue, resulting in kidney failure. Contact your physician immediately in the event of unresolved muscular pain, tenderness, or weakness. This is especially true when you experience unusual tiredness, a fever, and dark-colored urine.

Before you take this drug

Do not take Diovan if you have an allergy to the chemical valsartan. If you have diabetes, don't take Diovan together with any medication containing the ingredient aliskiren (a blood pressure medication). It may be necessary to stay clear of taking Diovan with the aliskiren in the event that you suffer from renal disease. To ensure that Diovan is safe for you, inform your doctor if you've ever experienced:

  • An unrelated heart condition to the one treated by Diovan.
  • If you're on a diet that has low salt levels.
  • The liver condition.
  • Kidney disease (or kidney disease if you're taking dialysis).

Avoid using it if you are expecting. Stop taking the medicine and inform your doctor when you discover that you are pregnant. Valsartan may cause death or injury to the unborn baby when you use the medication in the third or second trimester. Do not breastfeed.

How to take Diovan?

Follow Diovan exactly as directed by your physician. Follow the directions on the prescription label, and make sure you read all the prescription guides and instructions sheets. Your doctor may modify your dosage. Use the medicine daily at the same time every day, either with or without meals. If your child cannot take a tablet in its entirety, the pharmacist may mix the medication into a liquid. Your dosage requirements could be altered if you switch to an alternative version of the drug valsartan. Make sure you are using only the medicine that your doctor prescribes. Doses are determined by the weight of children and teens. Your child's dose could be altered if he or she is overweight or loses weight.

Your blood pressure is likely to be checked regularly. The kidneys may also require a check. Contact your physician if you have a fever, nausea, diarrhea, or sweat more than normal. It is possible to become dehydrated when you take Diovan. It could take between 2 and 4 weeks until your blood pressure is at a level that is manageable. If you are suffering from hypertension, you should continue using Diovan, even if you feel good. High blood pressure can have no signs. The treatment you receive could also involve fitness, diet and lifestyle modifications, and other medicines. Follow the instructions of your physician attentively. Keep at room temperature, away from heat and moisture.
