Medicines that cause blood vessels to dilate, or widen, are called vasodilators. They are used to treat heart failure and control high blood pressure because they cause blood vessels to relax so that blood can flow more easily through the body.
Edema is the medical term for swelling. It is a general response of the body to injury or inflammation. Edema can be isolated to a small area or affect the entire body. Medications, infections, pregnancy, and many medical problems can cause edema.
Edema results whenever small blood vessels become "leaky" and release fluid into nearby tissues. The extra fluid accumulates, causing the tissue to swell.
Follow the label directions on how often to take this medication. Take it at evenly spaced times, with meals, while you are awake.
The number of doses you take each day, the time allowed between doses and how long you need to take the medication will depend on your condition.
What Side Effects Could I Experience?
Possible side effects of vasodilators can include:
Headache; rapid, irregular or pounding heartbeat; numbness or tingling of the fingers or toes; loss of appetite and diarrhea: Your doctor will probably prescribe additional medication to control these side effects. If these symptoms are persistent or severe, contact your doctor.
Upset stomach, flushing of face or neck: Contact your doctor if these side effects are persistent or severe.
