Warfarin is the highest-priority interaction because CoQ10 may reduce its anticoagulant effect; INR monitoring and prescriber approval are required. Ask a qualified clinician before use with other anticoagulants or antiplatelets, blood-pressure or diabetes medicines, before surgery, or during pregnancy or breastfeeding. Do not use during chemotherapy or radiation unless the oncology team specifically approves it.\u003c\/p\u003e\n\n\u003cdiv style=\"border-left: 3px solid #B99A5B; background: #FBF8F1; padding: 12px 16px; margin: 20px 0;\"\u003e\n  \u003cp style=\"margin: 0;\"\u003e\u003cstrong\u003eSafety notice:\u003c\/strong\u003e This is a dietary supplement, not a medicine.

Do not combine L-tyrosine with monoamine oxidase inhibitors (MAOIs). Obtain prescriber approval before use with levodopa or other Parkinson’s medicines, thyroid medicines, prescription stimulants, decongestants, psychiatric medicines, high-dose caffeine, or other catecholamine-raising products.
