How propranolol is taken

Propranolol is typically taken orally and comes in tablet, capsule or liquid form. Since it can be used to treat such a wide range of conditions and comes in a variety of forms, there’s no ‘average’ dose and your doctor will be able to provide more information on the appropriate dosage for your condition.

However, once you’ve started taking propranolol, you shouldn’t stop or alter your dosage without speaking to a doctor first. Suddenly stopping can cause conditions to get worse, while changing the dosage could have a range of negative effects.

If you miss a dose, simply take the next one as soon as you remember. However, if it’s nearing the time that you’re scheduled to take your next dose, you shouldn’t take the missed dose. It’s important not to double up on doses, since this can cause a variety of unpleasant symptoms.

Things to avoid

Propranolol can interact with a wide range of different medications, including prescribed drugs, over-the-counter medicine and even herbal remedies, and can also have several negative effects on those dealing with existing conditions.

There are potentially hundreds of interactions, so it’s vital to ensure you discuss your current medication with your doctor before starting on a course of the drug. Just some of these include:


  • Other blood pressure medication
  • Drugs used to treat problems with heart rhythm
  • Various anaesthetics
  • Malaria medication
  • Phenothiazines
  • Asthma medication
  • Non-steroidal anti-inflammatory drugs like ibuprofen
  • Blood thinners

Omeprazole and alcohol

When taking propranolol, it’s usually not recommended to drink alcohol, since this can contribute to lower blood pressure caused by the drug.

It can also make side effects like dizziness and fainting more likely, so you should steer clear while taking the medication.

Is It Safe to Use Propranolol During Pregnancy?

Propranolol is rarely recommended for pregnant women and breastfeeding mums, since studies have shown it can have serious negative effects.

Beta blockers like this have been shown to increase the risk of birth defects and are usually only prescribed when there’s no other alternative.
