Edema is the medical term for swelling. Body parts swell from injury or inflammation. It can affect a small area or the entire body. Medications, infections, pregnancy, and many other medical problems can cause edema.
Edema happens when your small blood vessels become "leaky" and release fluid into nearby tissues. That extra fluid builds up, which makes the tissue swell.
Follow the label. If you are taking a single dose a day, take it in the morning with your breakfast or right afterward. If you’re taking more than one dose a day, take your last dose no later than 4 p.m.
The number of doses you take each day, the time between doses, and how long you need to take it will depend on the type of diuretic you’re prescribed and your condition.
Extreme tiredness or weakness: Both should get better as your body adjusts to the medication. If not, call your doctor.
Muscle cramps, thirst, loss of appetite, nausea, or vomiting: If you have any of these, make sure you’re taking your potassium supplement correctly, if you were prescribed one. Call your doctor if these symptoms last.
Dizziness, lightheadedness: Try getting up more slowly when you’re lying or sitting.
Blurred vision, confusion, headache, increased sweating, and restlessness: If these stick around a while or are severe, talk to your doctor.
