Your body usually balances the chemicals it produces, however sometimes it needs some help from outside forces. Amiloride is used specially to counteract hypertension
and congestive heart failure
. Usually these diseases come about from an overload of sodium in the body. In that case, Amiloride
, more commonly known to doctors as a Potassium-sparing diuretic, is used to keep potassium in the body but release sodium. More specifically, it keeps sodium and water from being absorbed in the kidneys
. Unlike other diuretics Amiloride keeps the potassium from seeping out as well. This helps normalize the functions of the heart
and the kidney
Sometimes because of the great potassium intake the body handles, patients using this drug experience hyperkalemia, which is a simply high blood
potassium level. Using ACE inhibitors and spironolactone
usually triggers this condition. However, this is easily managed by adjusting the dosage of Amiloride. And also, to help regulate the bodily fluids this drug is usually taken with thiazide and loop diuretics. Doctors usually prescribe Amiloride with another drug to combat the hyperkalemia.
Using drugs that increase the levels of potassium in the body is very delicate. If you are taking any medication for high blood pressure
, potassium supplements, or diabetes
then you should inform your doctor. Lithium is especially dangerous to be taking while on Amiloride. And also medication like captopril
, and lisinopril
can be dangerous when taking Amiloride. Drugs like spironolactone can increase your potassium to a dangerous level when taken with Amiloride, so inform your doctor about these and all other drugs that you are taking. If patients have had liver
, kidney or heart disease then they should inform their doctors immediately. Since Amiloride increases the body’s potassium, the organs recovering from diseases might be susceptible to the change. Having a renal disease is particularly hard if you plan on taking Amiloride since this makes the body more susceptible to hyperkalemia.
Amiloride has some common and negligible side effects like headache
, fatigue, upset stomach
, gas, nausea
, muscle cramps, and frequent urination
. Some rare side effects include impotence, vertigo
, heart burn, back and chest pain
. A difficult but common side effect is drowsiness, so patients on this drug should be careful not to drive or operate heavy machinery. Patients that experience skin rashes, yellow eyes or skin, difficulty breathing or an irregular heartbeat
should contact your doctor immediately. Side effects of a serious nature should always be reported to the treating physician.
Amiloride is usually sold under the name Midamor
in 5mg and 10 mg tablets. These tablets are usually yellow and diamond shaped. Doses usually start out at 5mg daily and then are slowly increased if the patient’s doctor sees fit, but higher doses usually put patients at risk for high blood potassium levels. The effects of the drug last the entire day, but usually it is the most effective 6-8 hours after first taking it. Since the aim of Amiloride is to regulate sodium levels, patients are encouraged to follow a low-sodium diet and exercise regularly. Also it is best to stay away from potassium rich foods like bananas, prunes and raisins while on Amiloride.
