Aspirin and heart disease
Blood thinners - aspirin; Antiplatelet therapy - aspirin
How Aspirin Helps You
Aspirin may be used to prevent heart or artery disease. It can also help prevent strokes.
Aspirin helps get more blood flowing to your legs. It can treat a heart attack and prevent blood clots when you have an abnormal heartbeat. You probably will take aspirin after you have treatment for clogged arteries.
You will usually take aspirin as a pill. Talk to your doctor before taking aspirin every day. Your doctor may change your dose from time to time.
Aspirin can have side effects: diarrhea, a skin rash, itching, nausea, or stomach pain. Before you start taking aspirin, tell your doctor if you have bleeding problems. Tell your doctor if have stomach ulcers. Also tell your doctor if you are pregnant or breastfeeding.
Take your aspirin with food and water. This can reduce side effects. You may need to stop taking this medicine before surgery or dental work. Always talk to your doctor before you stop taking this medicine. If you had a heart attack or a stent placed, be sure to ask your heart doctor if it is ok to stop taking aspirin.
You may need medicine for other health problems. Ask your doctor if this is safe.
If you miss a dose of your aspirin, take it as soon as possible. If it is time for your next dose, take your usual amount. Do NOT take extra pills.
Store your medicines in a cool, dry place. Keep them away from children.
