Generic Name: triamterene/hydrochlorothiazide (trye-AM-ter-een/HYE-droe-KLOR-oh-THYE-a-zide)
Brand Name: Examples include Dyazide and Maxzide
Dyazide can increase potassium levels in your body. This is more likely to occur in elderly patients, patients who are severely ill, or patients with kidney problems and diabetes. If not treated, high potassium levels can be fatal. Potassium levels must be closely monitored, especially in people with any of these problems or illnesses. Lab tests will be required, so be sure to keep your appointments. If you develop burning, numbness, or tingling; muscle weakness; tiredness; or an irregular heartbeat, notify your doctor right away.
Dyazide is used for:
Treating fluid retention (edema) and high blood pressure in certain patients. It may be used alone or with other medicines. It may also be used to treat other conditions as determined by your doctor.
Dyazide is a diuretic (water pill), and is a combination of a potassium-sparing diuretic (triamterene) and a thiazide diuretic (hydrochlorothiazide). It works by making the kidneys eliminate sodium (salt) and water from the body, which helps to lower blood pressure. The triamterene component helps minimize potassium loss.
Do NOT use Dyazide if:
- you are allergic to any ingredient in Dyazide or any other sulfonamide (eg, sulfamethoxazole)
- you are unable to urinate, or you have severe kidney problems or high blood potassium
- you are taking another potassium-sparing diuretic (eg, amiloride, spironolactone), another medicine that contains triamterene, an aldosterone blocker (eg, eplerenone), a salt substitute containing potassium, or dofetilide
Contact your doctor or health care provider right away if any of these apply to you.
Before using Dyazide:
Some medical conditions may interact with Dyazide. Tell your doctor or pharmacist if you have any medical conditions, especially if any of the following apply to you:

- if you are taking any prescription or nonprescription medicine, herbal preparation, or dietary supplement
- if you have allergies to medicines, foods, or other substances

- if you have a history of kidney stones or irregular heartbeat
- if you are on a low-salt (sodium) diet

Some MEDICINES MAY INTERACT with Dyazide. Tell your health care provider if you are taking any other medicines, especially any of the following:
- Aldosterone blockers (eg, epleronone), potassium-sparing diuretics (eg, amiloride, spironolactone), potassium supplements, or salt substitutes containing potassium because high blood potassium levels may occur
- Amphotericin B, corticosteroids (eg, prednisone), corticotrophin (ACTH), or chlorpropamide because the risk of blood electrolyte problems may be increased
- Nonsteroidal anti-inflammatory drugs (NSAIDs) (eg, indomethacin) because they may decrease Dyazide's effectiveness and the risk of kidney problems may be increased
- Angiotensin-converting enzyme (ACE) inhibitors (eg, enalapril) because the risk of high blood potassium and kidney problems may be increased by Dyazide
- Certain chemotherapy medicines or dofetilide because the risk of serious side effects may be increased by Dyazide
- Diazoxide, digoxin, or lithium because their actions and the risk of their side effects may be increased by Dyazide

How to use Dyazide:
Use Dyazide as directed by your doctor. Check the label on the medicine for exact dosing instructions.
- Take Dyazide by mouth with or without food. If stomach upset occurs, take with food to reduce stomach irritation.
- Dyazide may increase the amount of urine or cause you to urinate more often when you first start taking it. To keep this from disturbing your sleep, try to take your dose before 6 PM.
- If you take cholestyramine or colestipol, ask your doctor or pharmacist how to take it with Dyazide.
- Patients who take medicine for high blood pressure often feel tired or run down for a few weeks after starting treatment. Be sure to take your medicine even if you may not feel "normal." Tell your doctor if you develop any new symptoms.
- If you miss a dose of Dyazide, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.
Ask your health care provider any questions you may have about how to use Dyazide.
Important safety information:
- Dyazide may cause dizziness. This effect may be worse if you take it with alcohol or certain medicines. Use Dyazide with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.
- Dyazide may cause dizziness, light-headedness, or fainting; alcohol, hot weather, exercise, or fever may increase these effects. To prevent them, sit up or stand slowly, especially in the morning. Sit or lie down at the first sign of any of these effects.

- Dyazide has a sulfonamide called hydrochlorothiazide in it. Hydrochlorothiazide can cause certain eye problems (myopia, angle-closure glaucoma). Your risk may be increased if you are allergic to sulfonamide medicines (eg, sulfamethoxazole) or to penicillin antibiotics (eg, amoxicillin). Untreated angle-closure glaucoma can lead to permanent vision loss. If these eye problems occur, symptoms usually occur within hours to weeks of starting Dyazide. Contact your doctor right away if you experience symptoms such as vision changes (eg, decreased vision clearness) or eye pain.
- If vomiting or diarrhea occurs, you will need to take care not to become dehydrated. Contact your doctor for instructions.
- Tell your doctor or dentist that you take Dyazide before you receive any medical or dental care, emergency care, or surgery.
- Diabetes patients - Dyazide may affect your blood sugar. Check blood sugar levels closely. Ask your doctor before you change the dose of your diabetes medicine.

- Dyazide may interfere with certain lab tests. Be sure your doctor and lab personnel know you are taking Dyazide.
- Lab tests, including liver, kidney, or lung function; blood pressure; blood electrolyte levels (eg, potassium); and blood glucose levels, may be performed while you use Dyazide. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.
- Use Dyazide with caution in the ELDERLY; they may be more sensitive to its effects, especially high blood potassium levels.
- Dyazide should be used with extreme caution in CHILDREN; safety and effectiveness in children have not been confirmed.
