Why this happens

Omeprazole reduces the amount of acid in your stomach. Some aspirin tablets have a special coating (enteric coating) designed to dissolve only when they reach the gut. By making the stomach less acidic, omeprazole might cause this coating to break down too early in the stomach, or it may slightly alter how the aspirin is absorbed into the bloodstream. Despite this, the overall effect of the aspirin is usually not changed enough to be a concern.

You can take these medicines together. In fact, doctors often prescribe them together specifically to protect the stomach lining if you need to take aspirin long-term.
