Diovan HCT may cause birth defects or fetal death if you take it while you are pregnant. If you think you may be pregnant, contact your doctor right away. If you are planning to become pregnant, talk with your doctor about other treatment options.


Diovan HCT is used for:

Treating high blood pressure. It may also be used for other conditions as determined by your doctor.

Diovan HCT is an angiotensin II receptor blocker and diuretic combination. The angiotensin II receptor blocker works by relaxing the blood vessels. Exactly how the diuretic works to decrease blood pressure is not known, but it helps the kidneys to eliminate fluid and sodium from the body.

Do NOT use Diovan HCT if:

  • you are allergic to any ingredient in Diovan HCT or to any other sulfonamide medicine (eg, sulfamethoxazole)
  • you are pregnant
  • you are unable to urinate
  • you are taking a medicine that contains aliskiren and you also have diabetes or kidney problems. Check with your doctor or pharmacist if you are not sure if a medicine you take contains aliskiren
  • you are taking dofetilide or ketanserin

Contact your doctor or health care provider right away if any of these apply to you.
