Maxzide

Maxzide is a prescription medication used to treat high blood pressure and edema (swelling). It is a single medication containing two drugs, triamterene and hydrochlorothiazide. Triamterene and hydrochlorothiazide belong to a group of drugs called diuretics, which causes the kidneys to get rid of sodium and water while holding on to potassium.

This medication comes as a tablet. it is usually taken once daily, with or without food.

Common side effects of Maxzide include frequent urination, weakness, fatigue, and headache.

Maxzide can cause dizziness. Do not drive or operate heavy machinery until you know how this medication affects you.

Serious side effects have been reported with Maxzide including:

• Hyperkalemia: Maxzide can raise your body's potassium to harmful levels, possibly causing the heart to stop beating. Tell your doctor if you have kidney disease or diabetes.
• Metabolic or respiratory acidosis: Maxzide can increase your potassium levels, leading to acidosis.

  • difficulty breathing or swallowing
  • hoarseness
  • swelling

Maxzide can cause dizziness. Do not drive or operate heavy machinery until you know how it affects you.

Do not take Maxzide if you:

• have high potassium levels
• take other potassium-sparing medications such as spironolactone (Aldactone) and amiloride (Midamor)
• take potassium supplements
• have a history of poorly functioning kidneys
• are allergic to either triamterene or hydrochlorothiazide

Medications can interact with certain foods. In some cases, this may be harmful and your doctor may advise you to avoid certain foods. In the case of Maxzide, salt substitutes containing potassium should be avoided.

Before taking Maxzide, tell your doctor about all of your medical conditions. Especially tell your doctor if you:

• have a history of kidney, liver, heart, or parathyroid disease
• have diabetes
• have high potassium levels
• have a history of kidney stones, gout, or lupus
• are allergic to triamterene or hydrochlorothiazide
• have a history or glaucoma
• are pregnant or breastfeeding

Tell your doctor about all the medicines you take including prescription and non-prescription medicines, vitamins, and herbal supplements.

Tell your doctor if you are pregnant or plan to become pregnant.

The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.

Maxzide falls into category C. It is not known if Maxzide will harm your unborn baby. There are no well-controlled studies that have been done in pregnant women. This medication may be given to a pregnant woman if her healthcare provider believes that its benefits to the pregnant woman outweigh any possible risks to her unborn baby.

Tell your doctor if you are breastfeeding or plan to breastfeed.

You should not take Maxzide if you are breastfeeding. It may be excreted in your breast milk and may harm your nursing child.

Take Maxzide exactly as prescribed.

This medication comes as a tablet. it is usually taken once daily, with or without food.

If you miss a dose, take the missed dose as soon as you remember. If it is almost time for the next dose, skip the missed dose and take your next dose at the regular time. Do not take two doses of Maxzide at the same time.

Take Maxzide exactly as prescribed by your doctor. Follow the directions on your prescription label carefully.

Your doctor will prescribe the appropriate dosage depending on your condition and response to the medication. The dosages range from 37.5 to 75 mg (triamterene) and 25 to 50 mg (hydrochlorothiazide).

If you take too much Maxzide, call your healthcare provider or local Poison Control Center, or seek emergency medical attention right away.

• Store Maxzide at 20º to 25ºC (68º to 77ºF).
• Keep this and all medicines out of the reach of children.

Hyperkalemia

Abnormal elevation of serum potassium levels (greater than or equal to 5.5 mEq/liter) can occur with all potassium-conserving diuretic combinations, including Maxzide. Hyperkalemia is more likely to occur in patients with renal impairment, diabetes (even without evidence of renal impairment), or elderly or severely ill patients. Since uncorrected hyperkalemia may be fatal, serum potassium levels must be monitored at frequent intervals especially in patients first receiving Maxzide, when dosages are changed or with any illness that may influence renal function.
