Patient handout
Propranolol
You have been prescribed propranolol. This page explains what it is, what to expect, and when to call.
What it is
Propranolol is a beta-blocker, a blood-pressure medicine used here for the physical side of anxiety: the pounding heart, shaking hands, and trembling voice before a presentation, performance, or interview. It does not treat worry itself or generalized anxiety, and it is not habit-forming.
How to take it
- For performance anxiety, take it thirty to sixty minutes before the event, as prescribed. Take a test dose at home on a quiet day first to see how you respond.
- Do not take more than the prescribed amount in 24 hours.
- If prescribed daily, take it at the same times each day and do not skip days.
- With or without food.
What to expect, and when
- It works within thirty to sixty minutes and lasts about four to six hours.
- Your heart will feel steadier and your hands less shaky. Your thoughts will not change much, which is why it pairs best with practice and preparation.
- Mild tiredness or cold hands for a few hours are common.
- If you find you need it most days, tell us. A daily medication or therapy may serve you better.
Common side effects
Tiredness, cold hands and feet, dizziness or lightheadedness, slow heartbeat, vivid dreams, and, in some people, low mood or trouble sleeping with regular use.
Call the office the same day if
- Wheezing or trouble breathing (propranolol can tighten the airways; call 911 if severe)
- Fainting, or a heart rate below about 50 beats per minute with dizziness
- Chest pain or swelling of the legs
- Sweating, shakiness, or confusion if you have diabetes (it can mask low blood sugar)
- Rash, swelling of the face or lips, or trouble breathing (call 911)
Stopping
Occasional use can simply stop. If you take propranolol every day, do not stop abruptly: a sudden stop can cause a rebound rise in heart rate and blood pressure. We taper it together.
Good to know
- Do not take propranolol if you have asthma or another breathing condition unless we have discussed it. Tell us about diabetes, low blood pressure, a slow heart rate, or heart disease.
- Alcohol adds to the dizziness. Keep it light on days you use it.
- Tell other prescribers and your pharmacist, especially about other blood-pressure medicines and asthma inhalers.
