Medicines:

You may need any of the following:

• Antibiotics may be given to treat a bacterial infection.
• NSAIDs , such as ibuprofen, help decrease swelling, pain, and fever. NSAIDs can cause stomach bleeding or kidney problems in certain people. If you take blood thinner medicine, always ask your healthcare provider if NSAIDs are safe for you. Always read the medicine label and follow directions.
• Blood thinners help prevent blood clots. Clots can cause strokes, heart attacks, and death. Many types of blood thinners are available. Your healthcare provider will give you specific instructions for the type you are given. The following are general safety guidelines to follow while you are taking a blood thinner:
  • Watch for bleeding and bruising. 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 a blood thinner. Wear a bracelet or necklace that says you take this medicine.
  • Do not start or stop any other medicines or supplements unless your healthcare provider tells you to. Many medicines and supplements cannot be used with blood thinners.
  • Take your blood thinner exactly as prescribed by your healthcare provider. Do not skip a dose or take less than prescribed. Tell your provider right away if you forget to take your blood thinner, or if you take too much.
• 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.
• Take your medicine as directed. Contact your healthcare provider if you think your medicine is not helping or if you have side effects. Tell your provider 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.

Manage STP:

• Apply a warm compress to your arm or leg. This will help decrease swelling and pain. Wet a washcloth in warm water. Do not use hot water. Apply the warm compress for 10 minutes. Repeat this 4 times each day.
• Wear pressure stockings as directed. Pressure stockings improve blood flow and help prevent clots in your legs. Wear the stockings during the day. Do not wear them when you sleep.
• Elevate your leg or arm above the level of your heart as often as you can. This will help decrease swelling and pain. Prop your leg or arm on pillows or blankets to keep it elevated comfortably.

Prevent STP:

• Maintain a healthy weight. This will help decrease your risk for another blood clot. Ask your healthcare provider what a healthy weight is for you. Ask him or her to help you create a weight loss plan if needed.
• Do not smoke. Nicotine and other chemicals in cigarettes and cigars can damage blood vessels and increase your risk for blood clots. 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.
• Change your body position or move around often. Move and stretch in your seat several times each hour if you travel by car or work at a desk. In an airplane, get up and walk every hour. Move your legs by tightening and releasing your leg muscles while sitting. You can move your legs while sitting by raising and lowering your heels. Keep your toes on the floor while you do this. You can also raise and lower your toes while keeping your heels on the floor.
• Exercise regularly to help increase your blood flow. Walking is a good low-impact exercise. Talk to your healthcare provider about the best exercise plan for you.
• Do not inject non-prescription drugs. Talk to your healthcare provider if you need help to quit.

Follow up with your doctor or hematologist as directed:

You may need to come in regularly for scans to check for blood clots. Your blood may checked to see how long it takes to clot. Your doctor or specialist will tell you if you need to have this test and how often to have it. Write down your questions so you remember to ask them during your visits.
