Warnings

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.

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.
  • Myopia (nearsightedness) or glaucoma, or vision loss due to an increase in eye pressure: Tell your healthcare provider right away if you have some or all of the following symptoms of myopia or glaucoma:
    • sudden, severe pain in one eye
    • decreased or cloudy vision
    • nausea and vomiting
    • rainbow-like halos around lights
    • red eye
    • eye feels swollen
  • Electrolyte imbalances: Maxzide can dangerously alter your electrolyte levels. Electrolytes are important for the body to maintain normal functioning. Tell your doctor if you have a history of kidney disease.
  • Hepatic coma: Tell your doctor if you have a history of liver disease.
  • Renal stones: Treatment with Maxzide can cause kidney stones.
  • Hyperuricemia: Maxzide can increase your levels of uric acid, leading to gout. Symptoms of gout include:
    • pain
    • swelling
    • discolored, peeling, or itchy skin
  • Folic acid deficiency: Periodic blood tests are recommended for patients who may be affected by a decrease in folate levels.
  • Metabolic and endocrine effects: Maxzide can impair your body’s metabolism and endocrine system. Tell your doctor if you have diabetes or parathyroid problems.

    • swelling

Pregnancy

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.
