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?

Rationale: A. Docusate: Docusate is a stool softener that does not interfere with coagulation or increase bleeding risk. It is often safely used in clients taking anticoagulants to prevent straining during bowel movements, which is especially important in post-operative or cardiovascular patients. B. Cimetidine: While cimetidine may interact with some medications metabolized by the liver, it does not significantly affect bleeding risk when used with enoxaparin. However, it should still be used cautiously due to potential drug interactions and altered metabolism. C. Calcium supplement: Calcium supplements do not interfere with the anticoagulant action of enoxaparin. They are commonly used for bone health and are generally safe, provided they are taken at recommended doses without excessive vitamin D. D. Garlic: Garlic, especially in supplement form, can have antiplatelet effects and may increase the risk of bleeding when taken with anticoagulants like enoxaparin. Clients should be advised to avoid herbal products like garlic, ginkgo, or ginseng without provider approval.
