Edecrin (ethacrynic acid) is a loop diuretic (water pill) used to treat fluid retention (edema) in people with congestive heart failure, liver disease, or a kidney disorder such as nephrotic syndrome. Common side effects of Edecrin include:

Using too much Edecrin can lead to serious water and mineral loss (dehydration). Tell your doctor if you have unlikely but serious symptoms of dehydration including loss of appetite, confusion, severe dizziness, fainting, unusual dry mouth, thirst, severe headache, fast or irregular heartbeat, muscle cramps or spasms, nausea, vomiting, numbness and tingling, seizure, decrease in amount of urine, or unusual weakness or tiredness.

The smallest dose of Edecrin should be given to produce gradual weight loss (about 1 to 2 pounds per day). Onset of diuresis usually occurs at 50 to 100 mg for adults. After diuresis has been achieved, the minimally effective dose (usually from 50 to 200 mg daily) may be given on a continuous or intermittent dosage schedule. Edecrin may interact with lithium, digoxin, blood thinners, other diuretics, steroids, cancer medicines, cephalosporin antibiotics, aspirin and other salicylates, NSAIDs (nonsteroidal anti-inflammatory drugs), amikacin, gentamicin, netilmicin, streptomycin, or tobramycin. During pregnancy, Edecrin should be used only when prescribed. It is unknown if this drug passes into breast milk. Consult your doctor before breastfeeding.
