What drugs may interact with amiloride HCL?

- Nonsteroidal anti-inflammatory drugs (NSAIDs) (e.g., indomethacin), because they may decrease amiloride’s effectiveness and increase the risk of kidney problems and high blood potassium levels.

What is the dose of amiloride HCL for an adult?
The initial dose is 10mg, which may be given as a single or divided dose. This may be increased if necessary to a maximum of 20mg daily.
When diuresis has been achieved, the dosage may be reduced by 5mg increments to the least amount required.
In conjunction with other diuretic therapy:
When amiloride HCL is used with a diuretic which is given on an intermittent basis, it should be given at the same time as the diuretic.
Congestive heart failure:
The initial dose is 5-10mg daily, together with the usual dosage of the diuretic concurrently employed. Where diuresis is not achieved dosage of both agents may be increased if necessary, however, the maximum dose for amiloride HCL is 20mg a day.
Once diuresis is achieved, reduction in dosage of both agents may be attempted for maintenance therapy. The dosage of both drugs is determined by diuresis and the level of plasma potassium.
The recommended dose is 5-10mg daily, together with the usual antihypertensive dosage of the thiazide concurrently employed. It is not usually necessary to exceed 10mg of amiloride HCL daily; in any event, not more than 20mg a day should be given.
Hepatic cirrhosis with ascites:
When used in conjunction with another diuretic, treatment should be commenced with a small amiloride HCL dose of 5mg, plus a low dosage of the other diuretic agent. If necessary, dosage of both agents may gradually be increased until there is effective diuresis.
The maximum dose for amiloride HCL is 20mg daily. Maintenance doses may be lower than those required to initiate diuresis; reduction in the daily dosage should therefore be attempted when the patient’s weight is stabilized.
Dosage in the elderly should be carefully adjusted according to renal function, blood electrolytes and diuretic response. The elderly are more susceptible to electrolyte imbalance and more likely to experience hyperkalaemia since renal reserve may be reduced.
What is the dose of amiloride HCL for a child?
The dosage has not been established in pediatric patients. It may be unsafe for your child. It is always important to fully understand the safety of the drug before using. Please consult with your doctor or pharmacist for more information.
