Enoxaparin is a blood-thinning medicine that reduces the formation of harmful blood clots in your body.
This medicine is used to treat deep vein thrombosis (blood clots in the leg veins) and pulmonary embolism (blood clots in a lung artery). It is also used to prevent blood clots from forming in individuals with unstable angina (chest pain that occurs randomly or unexpectedly) or who have had a heart attack.
Enoxaparin may be used to treat other conditions as decided by your doctor.
Enoxaparin is to be injected subcutaneously (into the fatty layer under the skin, usually in the abdomen area).
Your doctor or nurse may administer the injection for you. If you or your caregiver had been given the proper training on the preparation and injection techniques of this medicine, you or your caregiver may do the administration.
Remember to rotate the injection sites. Do not inject into the same area all the time. New injection sites should be at least 1.5 inches away from the previous injection site. Do not inject near the navel (belly button).
This medicine is available as a pre-filled syringe or multidose vial. Make sure you know how to use the specific drug preparation you have been given. If you have problems or do not understand the instructions, ask your doctor or pharmacist.
The dose of this medicine will be decided by your doctor. Your doctor will advise you on the treatment timeframe depending on the type and severity of your disease.
Ensure that you keep all appointments with your doctor so that you do not miss any doses. Your doctor also needs to regularly monitor your response to Enoxaparin.
If you miss an appointment or miss an injection, alert your doctor or nurse. A replacement appointment or injection should be given as soon as possible.
If you or a caregiver had been trained to administer this medicine and missed a dose, inject the missed dose as soon as you remember and return to your normal dosing schedule.
DO NOT double a dose under any circumstances.
Inform your doctor or pharmacist immediately if you forgot to administer your dose.
