Common Side Effects of Propranolol Hydrochloride
Before taking propranolol, your doctor will want to know about any health conditions you have had and any medicines you take. Give your doctor a complete and up-to-date list of these. In the list of all the medicines that you take, include vitamins, over-the-counter medicines, herbal remedies, and supplements. Your doctor will want to check to make sure propranolol does not have interactions with your other medicines.

Propranolol comes as tablets, extended-release capsules, and a liquid form. Take propranolol as directed by your doctor. If you miss a dose, take it as soon as you realize it, unless it is almost time for the next dose. Do not double a dose to make up for a missed one.

Symptoms of a propranolol overdose include:
  • Slow or uneven heartbeat
  • Weakness
  • Dizziness
  • Fainting
It is important to take your propranolol exactly as directed, even if you feel well. Stopping propranolol can be dangerous and worsen your condition. Tell your doctor if you do not think propranolol is working for you.

Make sure other doctors you see know that you're taking propranolol. Propranolol can interfere with some medical tests. If you need any surgery, including dental procedures, tell your doctor or dentist that you are taking propranolol. Your doctor may decide to have you stop taking propranolol for a brief time.

If you have chest pain that gets worse or happens more often while taking propranolol, get emergency help, or call 911 right away.
