What should you know about OTC blood pressure medication?

Blood pressure medicines work in different ways, and the right choice depends on readings, kidney function, other conditions, pregnancy status, and medicines already being taken. A supplement or cold remedy marketed for circulation is not a replacement for antihypertensive treatment and may raise blood pressure or interact with prescribed drugs. Hypertension often causes no noticeable symptoms, so a headache alone cannot show what the pressure is or what treatment is needed.

Do not borrow, share, stop, or change a blood pressure prescription without advice. Rest quietly, use a validated monitor correctly, and record repeated readings with the time and any symptoms. A clinician may recommend home checks or ambulatory blood pressure monitoring to see how pressure changes through the day. Ask a pharmacist to review painkillers, decongestants, supplements, and herbal products before using them. Continue an existing prescription as directed unless a clinician tells you otherwise.

Call emergency services for chest pain, severe breathlessness, fainting, new weakness or numbness on one side, trouble speaking, confusion, or a sudden severe headache. These symptoms can occur with serious problems such as stroke or angina and should not be managed with a pharmacy product. Seek prompt advice for repeatedly high readings, pregnancy-related concerns, or troublesome medicine effects.

How should I measure and record my pressure? Do I need ambulatory monitoring? Could any of my current medicines be raising it? What should I do if I miss a dose or develop dizziness?
