What is Tekturna HCT?
Tekturna HCT contains a combination of hydrochlorothiazide and aliskiren. Hydrochlorothiazide is a thiazide diuretic (water pill) that helps prevent your body from absorbing too much salt, which can cause fluid retention. Aliskiren is an anti-hypertensive (blood pressure lowering) medicine. t works by decreasing substances in the body that narrow blood vessels and raise blood pressure.
Tekturna HCT is a prescription medicine used to treat high blood pressure (hypertension).
Tekturna HCT may be used to lower high blood pressure in adults when one medicine to lower high blood pressure is not enough. It may also be used as the first choice to lower high blood pressure if your doctor determines that you are likely to need more than one medicine.
You should not use Tekturna HCT if you are unable to urinate, or if you are allergic to sulfa drugs.
Do not use Tekturna HCT if you are pregnant. If you become pregnant, stop taking this medicine and tell your doctor right away.
If you have diabetes, do not use Tekturna HCT together with certain heart or blood pressure medicines (such as Accupril, Benicar, Capoten, Cozaar, Diovan, Lotensin, Mavik, Prinivil, Vasotec, any many others).
Before you take Tekturna HCT, tell your doctor if you have asthma, low or high levels of potassium in your blood, kidney or liver disease, glaucoma, gout, lupus, diabetes, or an allergy to sulfa drugs or penicillin.
You should not use Tekturna HCT if you are allergic to aliskiren or hydrochlorothiazide, or if you are also using itraconazole (Sporanox) or cyclosporine (Gengraf, Neoral, Sandimmune).
Do not use potassium supplements or salt substitutes while you are taking Tekturna HCT, unless your doctor has told you to. It may take up to 4 weeks for this medication to control your blood pressure. Keep using this medicine as directed, even if you feel well. High blood pressure often has no symptoms. You may need to use blood pressure medication for the rest of your life.
