Practical tips you can use today

Measure blood pressure at the same time each day and write down the results — that simple habit helps your clinician spot trends. If a medication makes you drowsy or dizzy, don’t drive until you know how it affects you. Never stop beta-blockers suddenly; missing doses or stopping abruptly can raise heart rate and blood pressure.

Watch for red flags: chest pain, fainting, severe shortness of breath, or a sudden blood pressure reading above 180/120 — those need immediate medical attention. For less urgent problems like persistent fatigue, swelling, or a new cough after starting a heart drug, book an appointment and bring a list of every medication and supplement you take.

If you’re buying meds online, pick pharmacies that require a prescription, show clear contact details, and have verifiable licensing. When in doubt, call your local pharmacist and ask if the product and dosing look right — pharmacists catch many errors before they become problems.
