Dyazide

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

Usage of Dyazide

Dyazide contains a combination of hydrochlorothiazide and triamterene. Hydrochlorothiazide is a thiazide diuretic (water pill) that helps prevent your body from absorbing too much salt, which can cause fluid retention.

Triamterene is a potassium-sparing diuretic that also prevents your body from absorbing too much salt and keeps your potassium levels from getting too low.

Dyazide is a prescription medicine used to treat fluid retention (edema) and high blood pressure (hypertension).

Dyazide is usually given to people in whom other diuretics have caused hypokalemia (low potassium levels in your blood).

Dyazide side effects

Get emergency medical help if you have signs of an allergic reaction to Dyazide (hives, difficult breathing, swelling in your face or throat) or a severe skin reaction (fever, sore throat, burning eyes, skin pain, red or purple skin rash with blistering and peeling).

Stop taking this medicine and call your doctor at once if you have:

blurred vision, tunnel vision, eye pain, or seeing halos around lights;

a light-headed feeling, like you might pass out;

fast, slow, or uneven heart rate;

signs of liver or pancreas problems - loss of appetite, upper stomach pain (that may spread to your back), nausea or vomiting, fast heart rate, dark urine, jaundice (yellowing of the skin or eyes);

high potassium level - nausea, weakness, tingly feeling, feeling weak or tired, slow heartbeats, loss of movement;

low potassium level - leg cramps, constipation, irregular heartbeats, fluttering in your chest, increased thirst or urination, numbness or tingling, muscle weakness or limp feeling;

Before taking Dyazide

You should not use Dyazide if you are allergic to hydrochlorothiazide or triamterene, or if:

you have kidney disease or are unable to urinate;

you have high potassium levels (hyperkalemia);

you are taking diuretics similar to triamterene, such as amiloride or spironolactone; or

you are taking potassium supplements (unless your doctor tells you to).

Diuretics such as triamterene can raise your blood potassium to dangerous levels. This is more likely to occur if you have kidney disease, diabetes, severe illness, or if you are an older adult. Ask your doctor about your individual risk.

To make sure Dyazide is safe for you, tell your doctor if you have ever had:

diabetes;

cirrhosis or other liver disease;

heart disease, heart rhythm disorder;

gout;

cataracts or glaucoma;

an allergy to sulfa drugs or penicillin;

kidney stones; o

if you are on a low-salt diet.

It is not known whether Dyazide will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant.

You should not breastfeed while using Dyazide.

Dyazide is not approved for use by anyone younger than 18 years old.

Warnings

You should not use Dyazide if have kidney disease, urination problems, high levels of potassium in your blood, or if you are taking other diuretics similar to triamterene. Do not use potassium supplements, salt substitutes, or low-sodium milk unless your doctor has told you to.

Dyazide can raise your blood potassium to dangerous levels, especially if you have kidney disease, diabetes, severe illness, or if you are an older adult. Call your doctor right away if you have signs of high potassium: nausea, slow or unusual heart rate, numbness, tingling, muscle weakness, or loss of movement in any part of your body.

Drinking alcohol can further lower your blood pressure and may increase certain side effects of Dyazide.

Avoid a diet high in salt. Too much salt will cause your body to retain water and can make this medication less effective.

Do not use potassium supplements, salt substitutes, or low-sodium milk while you are taking Dyazide, unless your doctor has told you to.

Avoid becoming overheated or dehydrated during exercise and in hot weather. Follow your doctor's instructions about the type and amount of liquids you should drink. In some cases, drinking too much liquid can be as unsafe as not drinking enough.
