Top 10 List of Safety Tips for Enoxaparin
| When taking enoxaparin (blood thinner) | |
|---|---|
| 1. | Take exactly as directed. Take enoxaparin the same time each day. Do not take extra doses or skip any doses. |
| 2. | Prepare exact dose. Ask your doctor, nurse, or pharmacist to teach you how to measure your dose.You may need to inject the full contents of a prefilled syringe, or discard a portion of the medicine in the syringe before injection. Do not expel the air bubble from the 30 mg and 40 mg syringes before injecting the medicine. It helps push the medicine into the body so it will not leak back out the injection site. |
| 3. | Inject the medicine. Follow the instructions below to inject the medicine into fatty areas of the abdomen, about 2 inches from the belly button. Do not inject the medicine into muscle, as this can cause a painful bruise. |
| 4. | Rotate injection sites. Write down the date, time, and location of the injection site for every dose. Use the opposite side of the abdomen each time you inject your medicine to prevent the skin from hardening. |
| To prevent the spread of diseases | |
| 5. | Don't reuse or recycle. Dispose of used syringes in a sealable hard plastic or metal container (e.g.,empty detergent bottle or a special sharps container from your pharmacy). Keep this container away from children. When the container is full, seal the lid before placing it in the trash. Do not recycle or reuse syringes. |
| To avoid serious side effects (bleeding) | |
| 6. | Tell your doctor about new medicines. Avoid starting or stopping other medicines without informingthe doctor who prescribed enoxaparin. This includes prescription medicines and nonprescription medicines such as aspirin, ibuprofen (Motrin, Advil), and naproxen (Aleve), which can increase your risk of bleeding. |
| 7. | Take precautions. Use an electric razor. Avoid sharp objects and fall risks (climbing a ladder, for example). |
| 8. | Tell your dentist and doctor. Let your physicians and dentists know you are taking enoxaparin before any surgery or procedure is scheduled and before any new medicine is prescribed or taken. |
| When you should call your doctor | |
| 9. | Signs of bleeding or clot. Call your doctor immediately if you experience any signs of bleeding or clot formation, which are listed below. |
| 10. | Injection site redness. Call your doctor if you develop redness, swelling, burning, or pain in the abdomen where you injected the medicine. |

Public Health Advisory
Caution with spinal anesthesia
Patients on enoxaparin who undergo spinal or epidural anesthesia or spinal puncture are at risk for bleeding into their spine. This may cause long-term or permanent paralysis. The risk of bleeding is greater in those who take nonsteroidal anti-inflammatory drugs such as Celebrex (celecoxib), Motrin (ibuprofen), and Aleve (naproxen). These patients should tell their doctor they are taking enoxaparin and immediately report any signs of spinal bleeding, especially tingling, numbness, and muscle weakness in the legs.
