A nurse is reinforcing teaching with a client who has a new prescription for enoxaparin. The nurse should identify which of the following over-the- counter products as unsafe for use with enoxaparin?

A. Garlic: Garlic supplements have antiplatelet properties that can increase the risk of bleeding when taken with anticoagulants like enoxaparin. Combining garlic with enoxaparin may potentiate hemorrhagic complications, requiring client education to avoid or monitor for bleeding. B. Docusate: Docusate is a stool softener that does not affect coagulation. It is safe to use with enoxaparin to prevent constipation, a common concern for clients on limited mobility or opioid therapy. C. Cimetidine: Cimetidine is an H2 receptor antagonist used for gastric acid suppression. It does not significantly interact with enoxaparin or alter its anticoagulant effect. It is generally safe for use concurrently. D. Calcium supplement: Calcium supplementation does not affect anticoagulation or platelet function. It is safe to use with enoxaparin and does not increase bleeding risk.
