While generally safe, LMWH may still cause side effects, such as: - Bleeding: The most common side effect, ranging from minor bleeding to major hemorrhage. - Thrombocytopenia: A reduction in platelet count, although less common than with UFH. - Hypersensitivity Reactions: Rare, but can include skin reactions at the injection site. - Osteoporosis: Prolonged use can lead to bone density reduction, particularly important during pregnancy.
