How It Works
ASA helps prevent the formation of
blood clots. This can decrease the chance that a blood clot will form and block
an already-narrowed artery.
Brand-name ASA is no more effective than generic or store
brands.
Why It Is Used
ASA may be given to people who
have
peripheral arterial disease (PAD). It may also be used after bypass surgery or
angioplasty to prevent the formation of blood clots
after these procedures.
How Well It Works
ASA may lower the risk for heart attack and stroke in people with peripheral arterial disease.1, 2
Side Effects
All medicines have side effects. But many people don't feel the side effects, or they are able to deal with them. Ask your pharmacist about the side effects of each medicine you take. Side effects are also listed in the information that comes with your medicine.
Here are some important things to think about:
- Usually the benefits of the medicine are more important than any minor side effects.
- Side effects may go away after you take the medicine for a while.
- If side effects still bother you and you wonder if you should keep taking the medicine, call your doctor. He or she may be able to lower your dose or change your medicine. Do not suddenly quit taking your medicine unless your doctor tells you to.
Call 911 or other emergency services right away if you have:
- Trouble breathing.
- Swelling of your face, lips, tongue, or throat.
- Coughing up blood, vomiting blood, or passing black, tarry, or bloody stools. (These are signs of bleeding inside your body.)
Call your doctor right away if you have any unusual bleeding, such as:
- Blood spots under your skin.
- A nosebleed that you cannot stop.
- Bleeding gums when you brush your teeth.
Call your doctor if you have:
Common side effects of this medicine include:
- Stomach pain or discomfort.
- Nausea.
See Drug Reference for a full list of side effects. (Drug
Reference is not available in all systems.)
What To Think About
Talk to your doctor before you start taking ASA every day.
For more information about taking daily ASA, see the topic Low-Dose ASA Therapy.
Taking medicine
Medicine is one of the many tools your doctor has to treat a health problem. Taking medicine as your doctor suggests will improve your health and may prevent future problems. If you don't take your medicines properly, you may be putting your health (and perhaps your life) at risk.
There are many reasons why people have trouble taking their medicine. But in most cases, there is something you can do. For suggestions on how to work around common problems, see the topic Taking Medicines as Prescribed.
Advice for women
If you are pregnant, breast-feeding, or trying to get pregnant, do not use any medicines unless your doctor tells you to. Some medicines can harm your baby. This includes prescription and over-the-counter medicines, vitamins, herbs, and supplements. And make sure that all your doctors know that you are pregnant, breast-feeding, or planning to get pregnant.
Checkups
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments. And call your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
