You may need any of the following:
- 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.
- Antiplatelets , such as aspirin, help prevent blood clots. Take your antiplatelet medicine exactly as directed. These medicines make it more likely for you to bleed or bruise. If you are told to take aspirin, do not take acetaminophen or ibuprofen instead.
- Prescription pain medicine may be given. Ask your healthcare provider how to take this medicine safely. Some prescription pain medicines contain acetaminophen. Do not take other medicines that contain acetaminophen without talking to your healthcare provider. Too much acetaminophen may cause liver damage. Prescription pain medicine may cause constipation. Ask your healthcare provider how to prevent or treat constipation.
- Take your medicine as directed. Contact your healthcare provider if you think your medicine is not helping or if you have side effects. Tell him or her 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.
You may be able to shower the day after your procedure. Remove your pressure bandage before you shower. Do not take baths or go in hot tubs or pools. Carefully wash around the wound with soap and water. Pat the area dry.
Care for your wound as directed:
Change your bandage when it gets wet or dirty. A small band-aid can be placed on your wound after you remove the pressure bandage. Monitor your wound everyday for signs of infection such as redness, swelling, or pus. Mild bruising is normal and expected. Do not put powders, lotions, or creams on your wound.
- Apply firm, steady pressure if bleeding occurs. A small amount of bleeding from your wound is possible. Apply pressure with a clean gauze or towel for 5 to 10 minutes. Call 911 if bleeding becomes heavy or does not stop.
- Do not lift anything heavier than 5 pounds for 48 hours. Heavy lifting can put stress on your wound and cause bleeding. Do not push or pull with the arm that was used for the procedure.
- Do not do vigorous activity for at least 48 hours. Vigorous activity may cause bleeding from your wound. Rest and do quiet activities. Short walks to the bathroom and around the house are okay. Do not walk or stand for more than 10 minutes. Ask your healthcare provider when you can return to your normal activities.
- Limit stair climbing to prevent bleeding from your wound. Plan activities on one floor and use stairs 2 times a day or less.
- Drink liquids to flush the contrast liquid from your body and prevent blood clots. Ask how much liquid to drink each day and which liquids are best for you.
- Restart your blood thinners as directed. Your healthcare provider may tell you to start taking your blood thinners after your procedure or he or she may have you wait a few days.
- Do not smoke. Nicotine and other chemicals in cigarettes and cigars can block your arteries. They can also increase your risk for heart disease, heart attack, and stroke. Ask your healthcare provider for information if you currently smoke and need help to quit. E-cigarettes or smokeless tobacco still contain nicotine. Talk to your healthcare provider before you use these products.
