Midamor FDA Prescribing Information: Side Effects
MIDAMOR (amiloride) is usually well tolerated and except for hyperkalemia (serum potassium levels greater than 5.5 mEq per liter † see BOXED WARNING), significant adverse effects have been reported infrequently. Minor adverse reactions were reported relatively frequently (about 20%) but the relationship of many of the reports to amiloride HCl is uncertain and the overall frequency was similar in hydrochlorothiazide treated groups. Nausea/anorexia, abdominal pain, flatulence, and mild skin rash have been reported and probably are related to amiloride. Other adverse experiences that have been reported with amiloride are generally those known to be associated with diuresis, or with the underlying disease being treated.
The adverse reactions for MIDAMOR (amiloride) listed in the following table have been arranged into two groups: (1) incidence greater than one percent; and (2) incidence one percent or less. The incidence for group (1) was determined from clinical studies conducted in the United States (837 patients treated with MIDAMOR (amiloride) ). The adverse effects listed in group (2) include reports from the same clinical studies and voluntary reports since marketing. The probability of a causal relationship exists between MIDAMOR (amiloride) and these adverse reactions, some of which have been reported only rarely.

|Body as a Whole|
Back pain |
Angina pectoris |
|Elevated serum potassium levels (> 5.5 mEq per Liter)***||None|
Skin rash |
Dryness of mouth
Joint pain |

** Reactions occurring in 3% to 8% of patients treated with MIDAMOR (amiloride) . (Those reactions occurring in less than 3% of the patients are unmarked.)
*** See BOXED WARNING.
Causal Relationship Unknown: Other reactions have been reported but occurred under circumstances where a causal relationship could not be established. However, in these rarely reported events, that possibility cannot be excluded. Therefore, these observations are listed to serve as alerting information to physicians.
- Activation of probable pre-existing peptic ulcer
