Drugs used to treat this and similar conditions

You may need extra oxygen

if your blood oxygen level is lower than it should be. You may get oxygen through a mask placed over your nose and mouth or through small tubes placed in your nostrils. Ask before you take off the mask or oxygen tubing.

Medicines:

• 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 help prevent blood clots. This medicine makes it more likely for you to bleed or bruise.

Tests:

You may need a series of blood tests to show how many platelets are in your blood. You may need blood tests every 2 to 3 days.

RISKS:

You may get a blood clot in your limb. This may become life-threatening. Medicines used to prevent or treat blood clots may cause bleeding. Without treatment, you may develop tissue death on a limb and need an amputation.
