Dyazide is a medication that is a combination of two diuretics (water pills) called triamterene and hydrochlorothiazide.

Dyazide is primarily used for treating fluid retention and high blood pressure in individuals who have developed or are at risk of developing hypokalemia (low potassium levels) with hydrochlorothiazide alone.

Dyazide works by blocking the reabsorption of water, sodium, and potassium at the cortical diluting segment of the distal tubule, thus promoting the elimination of excess salt and fluid from the body.

Use and Dosage

Take this medication by mouth as directed by your doctor, usually once daily in the morning with or without food. It is best to avoid taking this medication within 4 hours of your bedtime to prevent having to get up to urinate.

If you also take certain drugs to lower your cholesterol (bile acid-binding resins such as cholestyramine or colestipol), take this product at least 4 hours before or at least 4 to 6 hours after these medications.

The dosage is based on your medical condition and response to treatment.

Use this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day. Keep taking this medication even if you feel well. Most people with high blood pressure do not feel sick.

Tell your doctor if your condition does not improve or if it worsens (for example, if your blood pressure readings increase).

Before taking this medication, tell your doctor or pharmacist if you are allergic to triamterene or hydrochlorothiazide; or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.

Before using this medication, tell your doctor or pharmacist your medical history, especially of: diabetes, gout, high level of potassium in the blood, kidney disease (including kidney stones), liver disease, lupus, and skin cancer.

This drug may make you dizzy. Alcohol or marijuana (cannabis) can make you dizzier. Do not drive, use machinery, or do anything that needs alertness until you can do it safely. Limit alcoholic beverages. Talk to your doctor if you are using marijuana (cannabis).

Severe sweating, diarrhea, or vomiting can increase the risk of lightheadedness or dehydration. Report prolonged diarrhea or vomiting to your doctor. To prevent dehydration, drink plenty of fluids unless your doctor directs you otherwise.

If you have diabetes, this product may affect your blood sugar. Check your blood sugar regularly as directed and share the results with your doctor. Your doctor may need to adjust your diabetes medication, exercise program, or diet.

This medication may affect your potassium levels. Before using potassium supplements or salt substitutes that contain potassium, consult your doctor or pharmacist.

This medication may make you more sensitive to the sun. It may also increase your risk for skin cancer, especially if you take it for a long time. Limit your time in the sun. Avoid tanning booths and sunlamps. Use sunscreen and wear protective clothing when outdoors. Tell your doctor right away if you get sunburned, have skin blisters/redness, or notice new or changed moles/skin lesions.

Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).

Older adults may be more sensitive to the effects of this drug, especially dizziness, or high blood potassium levels.

During pregnancy, this medication should be used only when needed. It may harm an unborn baby. Discuss the risks and benefits with your doctor.

It is unknown if triamterene passes into breast milk. Hydrochlorothiazide passes into breast milk but is unlikely to harm a nursing infant. Consult your doctor before breastfeeding.

What happens if I miss a dose?

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.

What happens if I overdose?

Seek emergency medical attention.
