Does Omeprazole expire? 

Does Omeprazole expire? 

Yes, Omeprazole does expire. The formulation usually has a shelf life of about 3 to 4 years, depending on the brand and dosage. Powder for Omeprazole suspension can remain good for 2 to 3 years. 

However, once you have added water and made the suspension, it can not last more than 20-30 days in the refrigerator and hardly a week without a refrigerator. 

This is because adding water changes the form of the drug and the stability changes with it. Water is ideal for bacterial growth. Storing it at refrigerator temperature can slow down the process, but it can’t prevent it. 

What are the dangers associated with using expired Omeprazole? 

The possible outcome of taking an expired Omeprazole preparation is a therapeutic failure. This can result in painful consequences if Omeprazole is a part of your ulcer treatment regimen. 

If you’re a healthy person who’s taking an expired Omeprazole tablet to relieve heartburn, it won’t harm you. If it has expired for a month or two, you might be able to achieve the outcome you’re looking for. 

However, if it has expired for quite a while, you may not see any difference in your heartburn. The Food and Drug Administration (FDA) recommends avoiding using expired medications (1). 

There is no safety data available when it comes to the use of expired meds and there are potential risks. 

What to do if you have taken expired Omeprazole?

Expired Omeprazole will not cause a health risk and you don’t have to rush to the ER if you have accidentally consumed one. However, it is not recommended to continue using expired Omeprazole. It’s an OTC medication and you can easily get a new one without any prescription.
