Midamor is a medication approved by the FDA in the year 1967 for its use in retaining potassium in the body of patients who are suffering from diabetes or some other heart diseases. It contains Amiloride as its active constituent and works by preventing the kidneys from sending out potassium from the blood. It allows the salt and water to be filtered from the blood but not potassium. Listed as one of the essential medications by world health organization, this medication stays true to its functionality if it is administered in the right manner.

Medical Uses

Midamor is used to help balance the potassium levels in the body. Low potassium levels are a real danger in patients who have heart failure or hypertension and use other drugs to reduce the salt content in the blood. Due to this specific reason the drug is referred to as potassium-sparing diuretic. It is used in conjunction with other diuretics in the treatment of blood pressure.

Dosing guide

Midamor must be taken by mouth and along with food. A pill in the dosage strength of 5 mg is usually taken along with other antihypertensive or diuretic medication. If the dose is not enough, 2 tablets can be taken by having a daily dose of up to 10 mg. But usually the dose need not be increased more than 10 mg.

As there is a tendency to have increased urination while consuming Midamor, take the last dose before 6 pm to avoid any sleep disturbances. For patients with congestive heart failure, the potassium levels usually come to the desired levels after an initial dieresis. Such people must be monitored constantly and their dose must be re-evaluated.

People having high blood potassium levels, kidney disease or have trouble urinating should discuss it before a doctor before taking Midamor.
