Tekturna HCT is used for:

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

Tekturna HCT is a direct renin inhibitor and thiazide diuretic combination. The direct renin inhibitor works by relaxing blood vessels. The diuretic helps the kidneys to remove fluid from the body, which lowers blood pressure and helps the heart to pump blood more easily.

Do NOT use Tekturna HCT if:

  • you are allergic to any ingredient in Tekturna HCT or to any other sulfonamide (sulfa) medicine (eg, sulfamethoxazole)
  • you have a history of angioedema (swelling of the hands, face, lips, eyes, throat, or tongue; difficulty swallowing or breathing; or hoarseness) caused by treatment with Tekturna HCT or another product that contains aliskiren
  • you are pregnant
  • you have severe kidney problems or are unable to urinate
  • you have either diabetes or kidney problems and you are also taking an angiotensin-converting enzyme (ACE) inhibitor (eg, lisinopril) or an angiotensin receptor blocker (ARB) (eg, losartan)
  • you are taking cyclosporine, dofetilide, itraconazole, or ketanserin

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