Amiloride and hydrochlorothiazide

Generic name: Amiloride And Hydrochlorothiazide
Drug class: Potassium sparing diuretics with thiazides

Usage of Amiloride and hydrochlorothiazide

Amiloride and hydrochlorothiazide combination is used alone or with other medicines to treat high blood pressure (hypertension). High blood pressure adds to the workload of the heart and arteries. If it continues for a long time, the heart and arteries may not function properly. This can damage the blood vessels of the brain, heart, and kidneys, resulting in a stroke, heart failure, or kidney failure. High blood pressure may also increase the risk of heart attacks. These problems may be less likely to occur if blood pressure is controlled.

This medicine is also used to treat water retention (edema) in patients with congestive heart failure.

Amiloride and hydrochlorothiazide are both diuretic medicines (water pills). They reduce the amount of water in the body by increasing the flow of urine, which helps lower the blood pressure. Amiloride keeps your body from losing too much potassium when urine flow is increased.

This medicine is available only with your doctor's prescription.

Warnings

It is very important that your doctor check your progress at regular visits to make sure this medicine is working properly and to decide if you should continue to take it. Blood and urine tests may be needed to check for unwanted effects.

Hyperkalemia (high potassium in the blood) may occur while you are using this medicine. Check with your doctor right away if you have stomach pain, confusion, irregular heartbeat, nausea or vomiting, nervousness, numbness or tingling in the hands, feet, or lips, trouble breathing, or weakness or heaviness of the legs.

Make sure your doctor knows if you are also taking potassium supplements or salt substitutes containing potassium, or certain diuretics such as spironolactone (Aldactazide®, Aldactone®), triamterene (Dyrenium®), or other products containing amiloride. Using these medicines together may cause serious problems.

This medicine may make you dizzy or drowsy. Avoid driving, using machines, or doing anything else that could be dangerous if you are not alert. Dizziness may be worse if you lose too much water from your body. You can lose water by sweating, having diarrhea, or vomiting.

This medicine may increase your risk of getting skin cancer (eg, non-melanoma skin cancer). Avoid sun exposure. Use a sunscreen when you are outdoors. Avoid sunlamps and tanning beds. Talk to your doctor if you have concerns about this risk.

Alcohol, narcotic pain relievers, or sleeping pills may cause you to feel more lightheaded, dizzy, or faint when used with this medicine. Tell your doctor if you are drinking alcohol or using pain relievers or sleeping pills.

Do not take other medicines unless they have been discussed with your doctor. This especially includes over-the-counter (nonprescription) medicines for appetite control, asthma, colds, cough, hay fever, or sinus problems, since they may tend to increase your blood pressure.
