  • Blood thinners help prevent blood clots. Examples of blood thinners include heparin and warfarin. Clots can cause strokes, heart attacks, and death. The following are general safety guidelines to follow while you are taking a blood thinner:

    • Watch for bleeding and bruising while you take blood thinners. Watch for bleeding from your gums or nose. Watch for blood in your urine and bowel movements. Use a soft washcloth on your skin, and a soft toothbrush to brush your teeth. This can keep your skin and gums from bleeding. If you shave, use an electric shaver. Do not play contact sports.

    • Tell your dentist and other healthcare providers that you take anticoagulants. Wear a bracelet or necklace that says you take this medicine.

    • Do not start or stop any medicines unless your healthcare provider tells you to. Many medicines cannot be used with blood thinners.

    • Tell your healthcare provider right away if you forget to take the medicine, or if you take too much.

    • Warfarin is a blood thinner that you may need to take. The following are things you should be aware of if you take warfarin.

      • Foods and medicines can affect the amount of warfarin in your blood. Do not make major changes to your diet while you take warfarin. Warfarin works best when you eat about the same amount of vitamin K every day. Vitamin K is found in green leafy vegetables and certain other foods. Ask for more information about what to eat when you are taking warfarin.

      • You will need to see your healthcare provider for follow-up visits when you are on warfarin. You will need regular blood tests. These tests are used to decide how much medicine you need.

  • Prescription pain medicine may be given. Ask your PHP how to take this medicine safely.

  • Heart medicine is given to strengthen or regulate your heartbeat.

  • Diuretics decrease edema (excess fluid) that collects in a part of your body, such as your legs. Diuretics can also remove excess fluid from around your heart or lungs and decrease your blood pressure. You may urinate more often when you take this medicine.

  • Take your medicine as directed. Contact your PHP if you think your medicine is not helping or if you have side effects. Tell him if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits. Carry your medicine list with you in case of an emergency.

Follow up with your PHP or surgeon as directed:

Write down your questions so you remember to ask them during your visits.

Lifestyle changes:

  • Do not drink alcohol. Alcohol may worsen your heart condition or interact with your heart medicine. Tell your PHP if you drink alcohol and you need help to stop drinking.

  • Rest when you feel it is needed. Slowly start to do more each day. Return to your daily activities as directed.

Wound care:

Care for your wound as directed. When you are allowed to bathe or shower, you may need to carefully wash the incisions with soap and water. Dry the area and put on new, clean bandages as directed. Change your bandages when they get wet or dirty.

Contact your PHP or surgeon if:

  • You have a fever.

  • You have nausea or are vomiting.

  • You have redness, discharge, or pain in the incision area or where the catheter was inserted.

  • You have questions or concerns about your condition or care.

    • Trouble breathing
