This medication thins the blood and prevents blockage of blood vessels. It acts on certain blood elements involved in the coagulation process. Typically, it is used for deep vein thrombosis (blood clots). It may also be used for pulmonary embolism (a blood clot in the lungs). Even though you may not feel its effects, this medication takes effect within a few hours.

It must be injected under the skin (subcutaneously) in the abdominal region, according to the technique you were shown. Be sure to choose a different injection site each time.

WARNING: If you injure yourself, prolonged bleeding may occur. Report any excessive or unusual bleeding to your doctor. To reduce the risk of bleeding, do not consume alcohol, make any significant dietary changes, or take acetylsalicylic acid (ASA, e.g., Aspirin) unless prescribed by your doctor.
