The most common side effect of heparin is bruising more easily.
Heparin, an anticoagulant (blood thinner), works by preventing the formation of blood clots. While it's effective at preventing and treating dangerous clots, it can also increase the risk of bleeding. Bruising, which is bleeding under the skin, is a visible manifestation of this increased bleeding tendency.
Other common side effects of heparin include:
- Bleeding that takes longer to stop: Minor cuts and injuries may bleed for an extended period.
- Irritation, pain, redness, or sores at the injection site: This is localized and related to the method of administration (injection).
While bruising is often the most common and noticeable side effect, it's crucial to be aware of other potential, and more serious, adverse effects of heparin therapy, such as:
- Heparin-induced thrombocytopenia (HIT): A serious condition where heparin paradoxically causes a decrease in platelet count, increasing the risk of blood clots.
- Major bleeding: Bleeding in the gastrointestinal tract, brain, or other vital organs. This is less common but can be life-threatening.
If you are taking heparin and experience unusual or excessive bruising, prolonged bleeding, or any other concerning symptoms, you should contact your healthcare provider immediately. They can assess your situation and adjust your treatment plan if necessary.
