Dalteparin is prescribed to treat and prevent blood clots in certain situations. This "blood thinner" works by slowing down clot formation, allowing the body to naturally break down the clots. The most common side effects include pain at the injection site, bruising, and bleeding. Before using this medication, tell your healthcare provider if you have any allergies, a bleeding disorder, or high blood pressure.
Dalteparin sodium (Fragmin®) is a prescription medication approved to prevent blood clots in certain situations. In addition, it is approved to treat blood clots in people with cancer (but not in people without cancer). It is also approved to prevent complications in people who have recently had a heart attack or unstable angina (a type of chest pain that may indicate a heart attack is imminent). Dalteparin is taken by injection just below the skin.
As with any medicine, dalteparin may cause side effects. However, not everyone who uses it will experience side effects. In fact, many people tolerate it quite well.
If side effects do occur, in most cases, they are minor and either require no treatment or are treated easily by you or your healthcare provider. Serious side effects are less common, but do sometimes occur.
Some of the common side effects of this medication include:
- Pain at the injection site
- Elevated liver enzymes (found using a blood test).
