Patient question
Before buying OTC drugs or supplements, what should patients with cardiovascular disease check?
Answer reviewed by Gao Yuxia, Chief Physician
Professional answer
Tell the doctor or pharmacist your full medical conditions, allergy history, and all prescription drugs, OTC drugs, and supplements you are taking. Ask whether they may affect blood pressure, heart rate, bleeding risk, or existing treatment. Do not assume safety just because of 'natural' or 'health' labels, and do not use them as a substitute for proper medical care.
