How should I use Tekturna HCT
Use Tekturna HCT (Aliskiren Hydrochlorothiazide) exactly as directed on the label, or as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended.
Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose. Use the medicine exactly as directed.
You may take this medicine with or without food, but take it the same way every time. Avoid taking this medicine with a high-fat meal, which can make it harder for your body to absorb aliskiren.
You may have very low blood pressure while taking hydrochlorothiazide and aliskiren. Call your doctor if you are sick with vomiting or diarrhea, or if you feel light-headed.
It may take up to 4 weeks before your blood pressure improves. 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 medicine for the rest of your life.
Your blood pressure will need to be checked often.
Your doctor may also check your skin because hydrochlorothiazide can increase your risk of developing non-melanoma skin cancer. Ask your doctor about skin symptoms to watch for.
If you need surgery or medical tests, tell the surgeon ahead of time that you are using hydrochlorothiazide and aliskiren. You may need to stop using the medicine for a short time.
Store at room temperature away from moisture and heat.
Keep the tablets in their original container, along with the packet or canister of moisture-absorbing preservative.
Take the medicine as soon as you can, but skip the missed dose if it is almost time for your next dose. Do not take two doses at one time.
