Can you use expired Propranolol? 

Can you use expired Propranolol?

You can use a recently expired Propranolol and the drug will most likely work with its full potency. However, I would not recommend you to take Propranolol which has expired for over a year, especially if you have chronic hypertension or any active cardiac problem. 

What are the dangers associated with the use of expired Propranolol?

Propranolol does not necessarily become toxic once it expires and it can outlive its expiry date, but it gradually starts to become less potent. The thing with drug expiry is that there is no guarantee when the process of drug degradation begins. 

In fact, a drug can start to become less potent much earlier than another batch of the same drug, made by the same manufacturers. This is how tricky it is when it comes to expired meds as no one can tell you how much potency has already been lost (1). 

This is why it’s best to stick to the Propranolol which is still in effect. If you’re a long-term user, your Propranolol should get finished before it even comes near its expiry date. 

What to do if you have taken expired Propranolol?

There isn’t much to do if you have taken expired Propranolol as the drug will not harm you. However, it may not control your blood pressure effectively. This is why it’s best to talk to your healthcare provider and get a new prescription. 

If you happen to have a Propranolol bottle on your shelf, make sure you check the expiry date before you consume it. Going for a new batch of Propranolol is better than risking your health just to finish the expired one.
