The indication of Edecrin is the treatment of edema when an agent with greater diuretic potential is required despite other commonly used antidiuretics.


The oral capsules are available in 25 mg strength.

Side Effects

The most common side effects of Edecrin include:

  • Anorexia
  • Malaise
  • Abdominal pain
  • Nausea
  • Headache
  • Fatigue
  • Fever
  • Chills
  • Acute gout
  • hypoglycemia

For a full list of side effects that apply to you, reach out to your doctor or pharmacist.


General Weakness, muscle cramps, paresthesias, thirst, anorexia, and electrolyte abnormalities may occur following diuresis and these may be exacerbated by salt restriction.

Loop diuretics have been shown to increase the excretion of magnesium.

In some patients, NSAIDs can reduce the diuretic and antihypertensive effects of diuretics. Therefore, when Edecrin and NSAIDs are used, the patient should be observed closely to determine if the desired effect of the diuretic is obtained.


Common medications that interact with Edecrin are listed:

  • Lithium 
  • Aminoglycosides
  • Cephalosporins
  • NSAIDs
  • Warfarin 

For more information, do not hesitate to contact your doctor or pharmacist.


Store at controlled room temperature (77ºF). 

Pharmacist Tips

  • To prevent a rapid or substantial loss of fluid or electrolyte than is indicated or necessary, doses must be carefully regulated.
  • A few patients may require initial and maintenance doses as high as 200 mg twice daily. 

Higher doses, most frequently required in patients with severe, refractory edema, should be tapered up gradually.

  • It is usually possible to reduce the dosage and frequency of administration once the dry weight has been achieved.
