Taking omeprazole and sertraline together can increase the amount of sertraline in your bloodstream. This may increase the risk of side effects from sertraline, such as feeling sick (nausea), tremors, sleep problems, or feeling agitated. In rare cases, it could lead to a serious condition called serotonin syndrome, which causes high body temperature, sweating, and confusion.

Why this happens
Sertraline is broken down in the liver by certain proteins (enzymes). Omeprazole can slow down these proteins, which means the sertraline stays in your body longer and reaches higher levels than intended.
What you should do
You can take these medicines together, but you should be aware of increased side effects. If you notice you are feeling more anxious, shaky, or unwell after starting omeprazole, speak to your doctor. They may suggest a lower dose of sertraline or a different type of indigestion medicine (like famotidine or lansoprazole) that is less likely to interfere.
