Millions of people have high blood pressure. If you\u2019re one of them, you\u2019ll probably have a cold, allergies, or aches and pains at one time or another. Before you reach for help at the drug store, you need to know that some over-the-counter medicines may not be safe for you to take.\nIt\u2019s good for everyone, whether you have high blood pressure or not, to know that over-the-counter doesn\u2019t mean risk-free. You can learn how to stay safe by talking to your doctor and following a few simple rules.\nWhat Is High Blood Pressure?\nHigh blood pressure, also called hypertension, typically refers to blood pressure that is 140\/90 or above. Blood pressure of 180\/120 is considered severe hypertension.\nThe first number is your systolic blood pressure, which is your blood pressure when your heart beats while pumping blood. The second number is your diastolic blood pressure, which is your blood pressure when the heart is at rest between beats.\nFor reference, normal blood pressure for adults is around 120\/80, and this can increase when you\u2019re excited, scared, or active, but should return to normal fairly quickly.\nRELATED:\u00a0Am I at Risk for High Blood Pressure?\nWhat Is the Difference Between OTC and\u00a0Prescription Medicines\nOver-the-counter (OTC) medicines are drugs you can buy without a prescription from your doctor.

Always read the labels and talk to your doctor or pharmacist if you aren\u2019t sure what something means.\nRemember: taking OTC medicines without taking to your doctor can put you at risk if your blood pressure is high.
