Before Using This Medicine

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For potassium-sparing diuretics, the following should be considered:

Allergies - Tell your doctor if you have ever had any unusual or allergic reaction to amiloride, spironolactone, or triamterene. Also tell your health care professional if you are allergic to any other substances, such as foods, preservatives, or dyes.

Pregnancy - Studies have not been done in pregnant women. However, this medicine has not been shown to cause birth defects or other problems in animals.

In general, diuretics are not useful for normal swelling of feet and hands that occurs during pregnancy. Diuretics should not be taken during pregnancy unless recommended by your doctor.

Breast-feeding - Although amiloride, spironolactone, and triamterene may pass into breast milk, these medicines have not been reported to cause problems in nursing babies.

Children - This medicine has been tested in children and, in effective doses, has not been shown to cause different side effects or problems in children than it does in adults.

Older adults - Signs and symptoms of too much potassium are more likely to occur in the elderly, who are more sensitive than younger adults to the effects of this medicine.

Other medicines - Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary.

  • Lithium (e.g., Lithane) - Use with potassium-sparing diuretics may cause high blood levels of lithium, which may increase the chance of side effects

Other medical problems - The presence of other medical problems may affect the use of potassium-sparing diuretics. Make sure you tell your doctor if you have any other medical problems, especially:

  • Diabetes mellitus (sugar diabetes) or
