In this session, we will be discussing the consumer medication information for triamterene/hydrochlorothiazide, trade name DyazideTM and MaxzideTM.
What it’s for & How to take
Triamterene/Hydrochlorothiazide increases the amount of urine you will eliminate. This medication helps your body get rid of extra water and salt. Triamterene/hydrochlorothiazide is used to treat a buildup of fluid in your body, called edema. This medication is also used to treat high blood pressure.
Edema is when you have extra fluid in your body that causes swelling in your hands, feet or ankles. You may also feel shortness of breath or fluid in your abdomen. This is usually caused by some heart problem or a disease of your kidney or liver. Increasing the amount of urine you eliminate will help get rid of some of the extra fluid and decrease the symptoms of edema.
If high blood pressure is not treated, your blood vessels will harden, and this will eventually lead to a heart attack or a stroke. High blood pressure may also cause vision problems, kidney failure and eventually heart failure.
Triamterene/hydrochlorothiazide is usually taken 1-2 times daily or as directed by your doctor. This medication may be taken with or without food. If you are taking this medication twice daily, take the second dose in the afternoon, not at bedtime. Taking triamterene/hydrochlorothiazide at bedtime may cause you to get up to urinate after you have already gone to bed.
If you forget to take a dose, take it as soon as you remember. If it is near the time of your next dose, skip it and continue with your normal dose time. Do not take a double dose to make up the missed dose.
If you are taking triamterene/hydrochlorothiazide to treat your blood pressure, keep using this medication, even if you don’t feel sick. You may need to treat your high blood pressure for many years.
Your blood pressure should be checked often to make sure the medication is working correctly. You may need to have regular blood tests done while taking this medication. Lab tests are done to see how your body tolerates this medication.
