Propranolol
About Propranolol
Propranolol is a prescription medication used to manage high blood pressure, chest pain (angina), and uneven heartbeats. It is also commonly prescribed to help prevent migraine headaches, reduce essential tremors, and manage the physical symptoms of situational anxiety. By helping to ease the strain on your heart and blood vessels, this medicine helps keep your cardiovascular system running smoothly.
To get the most benefit, you should take Propranolol consistently at the same times every day, exactly as your doctor has directed. You can take this medicine with or without food, but it is important to choose one way and stick to it with every dose. Making healthy lifestyle choices, such as eating a low-salt diet and getting regular gentle exercise, can further support the medicine's effects on your heart health.
Some people may experience mild side effects like tiredness, cold fingers or toes, or trouble sleeping when they first start taking this medicine. If you notice any serious side effects, such as a very slow heart rate, severe dizziness, or shortness of breath, you should contact your doctor immediately.
Talk to your doctor before starting Propranolol if you have a history of asthma, chronic obstructive pulmonary disease (COPD), diabetes, or certain heart conditions like heart block. Do not take this medicine if you have a very slow heart rate, severe low blood pressure, or uncontrolled heart failure.
This medicine can interact with alcohol, which may cause your blood pressure to drop too low, and smoking, which can reduce how well the medicine works. If you are pregnant, planning to become pregnant, breastfeeding, or are an older adult, consult your doctor to ensure this treatment is safe for you.

Patients Concern
Disease/Condition Glossary
Blood pressure: Blood pressure is the force that the heart uses to pump blood around the body, and when it stays too high (a condition called hypertension), it can strain the heart, harden blood vessels, reduce blood flow, and lead to serious problems like chest pain, heart attack, stroke, or kidney failure. A healthy reading of blood pressure is usually between 90/60 mmHg and 120/80 mmHg, where the top number (systolic) shows the pressure when the heart beats, and the bottom number (diastolic) shows the pressure when the heart rests.
