Safe Use of Anticoagulants
WHAT YOU NEED TO KNOW:
Anticoagulants are medicines used to treat or prevent blood clots by thinning your blood. These medicines can be used to treat conditions, such as pulmonary embolism or venous thrombosis. The medicines may be used to prevent deep vein thrombosis (DVT) or blood clots after surgery or long-term bedrest.
Return to the emergency department if:
- You have a nose bleed that lasts longer than 10 minutes.
- You cough up or vomit blood.
- You have a sudden, severe headache, or you cannot move one side of your body.
- You are dizzy and cannot keep your balance.
- You are confused or have trouble speaking.
- You have difficulty breathing or chest pain.
Contact your healthcare provider if:
- You forget to take your medicine or you take too much.
- You have nausea, and you are vomiting.
- You bleed when you brush your teeth or blow your nose.
- Your urine or bowel movements are dark in color or have blood in them.
- You have excessive bruising or your legs have reddish-purple spots that look like a rash.
- You have a sore throat, fever, and chills.
- You become pregnant.
- You have questions or concerns about your condition or care.
Take your anticoagulants safely:
- Always take your medicine exactly as prescribed by your healthcare provider. Take your medicine at the same time every day. This will help keep a steady level of medicine in your body.
- Take 1 dose of medicine at a time. If you forget to take a dose, do not take 2 doses. Too much anticoagulant in your body may increase your risk of bleeding and change medicine levels in your blood.
- Do not stop taking your medicine. Follow your healthcare provider's directions.
- Do not take aspirin or products containing aspirin unless prescribed by your healthcare provider. Many over-the-counter medicines contain aspirin. Aspirin may increase your risk of bleeding.
- Do not start or stop taking any other medicines (prescribed or over the counter) or supplements. Ask your healthcare provider before changing any medicine or supplement. Certain medicines and supplements can cause excessive bleeding or cause your anticoagulant to not work properly.
Tell all of your healthcare providers that you are taking anticoagulants. Keep a current list of medicines and their dosages with you at all times.
- Wear a bracelet or necklace that says you take this medicine.
- You may need regular blood tests so your healthcare provider can decide how much medicine you need. The dose may need to be changed because of your test results. Write down changes to your dose of medicine.
- Use a soft washcloth and a soft toothbrush. If you shave, use an electric razor. Avoid activities that can cause bruising or bleeding.
- If you take warfarin, some foods can change how your blood clots. Do not make major changes to the foods you eat while you are taking warfarin. Warfarin works best when you eat about the same amount of vitamin K every day. Vitamin K is found in green leafy vegetables, broccoli, grapes, and other foods. Ask for more information about what to eat when you take warfarin.
- Avoid drinking alcohol while taking anticoagulants. Alcohol can increase your risk of bleeding.
