Dyazide contains triamterene and hydrochlorothiazide, two diuretics that work together to help the body remove extra salt and water while reducing excessive potassium loss. It is mainly used to treat high blood pressure and edema in people who need hydrochlorothiazide but are at risk of developing low potassium levels.

High Blood Pressure

Dyazide may be prescribed to help control hypertension, or high blood pressure. High blood pressure makes the heart work harder and can gradually damage blood vessels, the heart, kidneys, and other organs.

Hydrochlorothiazide helps the kidneys remove extra sodium and water through urine. This reduces the amount of fluid circulating in the bloodstream, which can help lower blood pressure.

Triamterene is added because hydrochlorothiazide can sometimes cause potassium levels to become too low. Triamterene helps the body hold onto more potassium while still allowing excess fluid to be removed.

Edema and Fluid Retention

Dyazide may also be used to treat edema, which means excess fluid has collected in the body’s tissues.

Edema may cause swelling in the legs, ankles, feet, or other areas. By increasing urine production, Dyazide helps the body remove excess sodium and water, which can reduce this swelling.

The combination is particularly intended for people who develop low potassium while taking hydrochlorothiazide alone or who need a thiazide diuretic but cannot safely risk developing low potassium.

How Does Hydrochlorothiazide Work?

Hydrochlorothiazide is a thiazide diuretic, sometimes called a water pill.

It acts on the kidneys and increases the removal of sodium and water through urine. As the body loses excess fluid, swelling may decrease and blood pressure may become easier to control.

However, hydrochlorothiazide can also increase potassium loss. This is why it is combined with triamterene in Dyazide.

How Does Triamterene Work?

Triamterene is a potassium-sparing diuretic.

It also helps the kidneys remove sodium and water, but unlike hydrochlorothiazide, it reduces potassium loss. This helps lower the chance that potassium levels will fall too low during treatment.

Triamterene does not always completely prevent low potassium, and in some people it can cause potassium to become too high, so blood tests may be needed during treatment.

Why Are These Two Diuretics Combined?

The two ingredients are combined because they complement each other.

Hydrochlorothiazide provides much of the blood pressure-lowering and fluid-removing effect, while triamterene helps limit the potassium loss caused by hydrochlorothiazide.

This makes Dyazide especially useful for people who need a thiazide diuretic but have already developed hypokalemia, or low potassium, or are considered at higher risk for it.

Is Dyazide Usually the First Treatment Used?

Not always. Current prescribing information states that the triamterene-hydrochlorothiazide combination is generally not intended as the first treatment for high blood pressure or edema, unless avoiding low potassium is particularly important.

It is commonly considered when hydrochlorothiazide alone has caused low potassium or when a healthcare provider believes that low potassium could be especially risky.

Can Dyazide Be Used With Other Blood Pressure Medicines?

Yes. Dyazide may sometimes be used together with other antihypertensive medicines.

Because combining blood pressure medicines can lower blood pressure more strongly, your healthcare provider may need to adjust the doses and monitor you for dizziness, weakness, or blood pressure that becomes too low.

Why Is Potassium Monitoring Important?

Potassium is an important mineral that helps control the normal function of the heart, muscles, and nerves.

Hydrochlorothiazide may lower potassium, while triamterene may raise it. Although combining the two helps balance these effects, potassium can still become either too low or too high in some people.

Your healthcare provider may therefore order blood tests to check your potassium level, kidney function, and other electrolytes during treatment.

Does Dyazide Cure High Blood Pressure?

No. Dyazide helps control high blood pressure, but it does not permanently cure it.

You may need to continue taking the medication even if you feel well because high blood pressure often does not cause noticeable symptoms. Do not stop taking Dyazide unless your healthcare provider tells you to.

Important Reminder

Dyazide combines hydrochlorothiazide, a thiazide diuretic, with triamterene, a potassium-sparing diuretic. Together, they help remove excess salt and water while reducing the risk of potassium becoming too low.

Dyazide is mainly used for hypertension or edema in people who develop low potassium with hydrochlorothiazide alone or in whom low potassium needs to be avoided. Because the medication can affect potassium levels, kidney function, blood pressure, and fluid balance, regular monitoring may be needed during treatment.

Dyazide contains triamterene and hydrochlorothiazide and is taken by mouth as a tablet. It should be used exactly as directed by your healthcare provider.

The usual dose is one or two tablets taken once daily. Each commonly used tablet contains 37.5 mg of triamterene and 25 mg of hydrochlorothiazide. Your healthcare provider will decide whether you need one or two tablets based on your blood pressure, swelling, potassium level, kidney function, and response to treatment.

When Should You Take Dyazide?

Dyazide is often taken in the morning because it increases urine production.

Taking it earlier in the day can make it less likely that you will need to wake up during the night to urinate. If your healthcare provider gives you a different schedule, follow their instructions.

Try to take your dose at about the same time every day. This makes the medication easier to remember and helps you follow a consistent treatment routine.

Can Dyazide Be Taken With Food?

Dyazide can generally be taken with or without food. If it causes stomach discomfort, ask your healthcare provider or pharmacist whether taking it with food may help.

Swallow the tablet with water. Do not take more tablets than prescribed.

Recommended Dosage

For triamterene/hydrochlorothiazide tablets containing 37.5 mg/25 mg, the usual dosage is one or two tablets once daily. Potassium levels and your response to treatment should be monitored while you are taking the medication.

Taking more than the prescribed amount can increase the risk of problems with potassium, sodium, fluid balance, blood pressure, and kidney function.

Why Does the Dose Need to Be Individualized?

Dyazide affects both fluid levels and electrolytes in your body.

Hydrochlorothiazide helps the kidneys remove extra sodium and water, while triamterene helps reduce potassium loss. However, triamterene can sometimes cause potassium to become too high.

For this reason, your healthcare provider may order blood tests to monitor your:

  • Potassium level
  • Sodium and other electrolytes
  • Kidney function
  • Blood pressure

The dose may be adjusted depending on these results and how well your symptoms are controlled.

Taking Dyazide for High Blood Pressure

If you are taking Dyazide for hypertension, continue taking it even if you feel well.

High blood pressure often does not cause obvious symptoms, so feeling normal does not necessarily mean your blood pressure is controlled without medication.

Your healthcare provider may check your blood pressure regularly to see whether your treatment is working.

Taking Dyazide for Edema

If you are taking Dyazide for fluid retention or swelling, you may notice that you urinate more after taking the medication.

Over time, removing excess fluid can help reduce swelling in areas such as the feet, ankles, and legs.

Your healthcare provider may also monitor your weight because sudden changes in body weight can sometimes reflect changes in fluid retention.

Drink Fluids as Directed

Because Dyazide increases the removal of water from your body, dehydration can occur if too much fluid is lost.

However, this does not mean everyone taking Dyazide should automatically drink extra water. Some people with heart, kidney, or liver problems may have restrictions on how much fluid they should drink.

Follow your healthcare provider’s instructions about your daily fluid intake.

Be Careful With Potassium

Do not start potassium supplements or potassium-containing salt substitutes unless your healthcare provider recommends them.

Triamterene helps the body retain potassium, so taking additional potassium may cause potassium levels to become dangerously high in some people.

What If You Miss a Dose?

If you forget a dose, take it when you remember unless it is almost time for your next scheduled dose.

If your next dose is due soon, skip the missed dose and continue with your normal schedule. Do not take extra tablets to make up for a missed dose.

Do Not Stop Dyazide on Your Own

Do not stop taking Dyazide simply because your blood pressure improves or your swelling goes away.

Stopping treatment may cause your blood pressure or fluid retention to worsen. Speak with your healthcare provider before making any changes to your treatment.

What If You Take Too Much?

Taking too much triamterene/hydrochlorothiazide can cause serious problems with electrolytes and fluid balance. Symptoms may include increased urination, nausea, vomiting, weakness, and low blood pressure.

If you take significantly more than prescribed, seek medical advice promptly.

Important Reminder

The usual dose of Dyazide is one or two 37.5 mg/25 mg tablets taken once daily. Take it at the same time each day, preferably earlier in the day if possible, and use only the amount prescribed by your healthcare provider.

Because Dyazide can affect potassium levels, kidney function, blood pressure, and hydration, regular monitoring may be needed throughout treatment.

Your healthcare provider may order blood tests to monitor your kidneys while you are taking this medication. Tell them if you notice a major decrease in urination, swelling, or unusual weakness.

Liver Problems

Use Dyazide carefully if you have liver disease. Changes in fluid and electrolyte levels can be more serious in people with severe liver problems.

Tell your healthcare provider if you have a history of liver disease before starting treatment.

Gout and High Uric Acid

Hydrochlorothiazide, one of the ingredients in Dyazide, can increase uric acid levels in the blood.

This may trigger or worsen gout attacks in some people. Tell your healthcare provider if you have gout or a history of high uric acid levels.

Allergic Reactions

Some people may have an allergic reaction to Dyazide.

Seek immediate medical care if you develop hives, severe rash, swelling of the face, lips, tongue, or throat, or difficulty breathing.

Blood Sugar Changes

Dyazide may affect blood sugar levels.

If you have diabetes, your healthcare provider may recommend checking your blood sugar more closely. The dose of insulin or other diabetes medicine may sometimes need to be adjusted.

Pregnancy and Breastfeeding

If you are pregnant, planning to become pregnant, or breastfeeding, talk to your healthcare provider before taking Dyazide.

Your healthcare provider can review the possible benefits and risks and decide whether this medication is appropriate for you.

Medication Interactions

Dyazide can interact with other medicines, including lithium, digoxin, other blood pressure medicines, potassium supplements, and medications that can affect kidney function or potassium levels.

Before starting Dyazide, tell your healthcare provider about all prescription medicines, over-the-counter products, vitamins, and supplements you take.

Important Reminder

Because Dyazide can affect kidney function, potassium, sodium, blood sugar, uric acid, and fluid balance, regular blood tests may be needed during treatment.

Do not start potassium supplements, potassium-containing salt substitutes, or new medications without first checking with your healthcare provider.

What Should I Do If I Miss a Dose of Dyazide?

If you miss a dose of Dyazide, take it as soon as you remember. However, if it is almost time for your next scheduled dose, skip the missed dose and continue with your regular schedule. Do not take two doses at the same time or take extra medicine to make up for the missed dose.

Can Dyazide Be Used During Pregnancy or Breastfeeding?

If you are pregnant, planning to become pregnant, or breastfeeding, talk to your healthcare provider before taking Dyazide. Your healthcare provider can review the possible benefits and risks and decide whether this medication is appropriate for you.

What Should I Avoid While Taking Dyazide?

Avoid using potassium supplements or potassium-containing salt substitutes unless your healthcare provider specifically recommends them. Triamterene, one of the ingredients in Dyazide, can increase potassium levels in the blood. Alcohol may also increase dizziness or lightheadedness, especially when standing up quickly. Use caution until you know how Dyazide affects you. Before starting any new prescription medicine, over-the-counter medication, vitamin, or supplement, check with your healthcare provider or pharmacist to make sure it is safe to use with Dyazide.
