Medicines that make your blood vessels get wider are called vasodilators. They’re used to treat heart failure and control high blood pressure because they cause your blood vessels to relax so that all-important fluid can flow more easily through your body.
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 to find out how often you should take them. Make it at evenly spaced times, with meals, while you are awake.
The number of doses you take each day, the time between doses, and how long you’ll need to take them will depend on your condition.
What Side Effects Could I Have?
Headache; rapid, irregular, or pounding heartbeat; numbness or tingling of the fingers or toes; loss of appetite; and diarrhea: Your doctor probably will prescribe more medicine to control these. If they linger or are severe, talk to your doctor.
Upset stomach, flushing of face or neck: Call your doctor if these side effects hang around or get serious.
If you get any of these, contact your doctor right away:
