can you drink alcohol on propranolol

Drinking alcohol while taking propranolol is generally not recommended because it can worsen side effects such as dizziness, lightheadedness, and drowsiness. Alcohol can amplify propranolol's blood pressure-lowering effects and increase the risk of fainting or falls. Although alcohol does not directly interfere with the medication's core function, it can increase propranolol's levels in the blood, making side effects more pronounced. It may be safer to avoid alcohol entirely when first starting propranolol or adjusting the dose. For immediate-release propranolol, having a drink about 8 hours after a dose may be safer, but this should only be done under medical advice. People with heart conditions, older adults, and those on other medications should be especially cautious or avoid alcohol altogether while on propranolol.
