how long does it take omeprazole to work

Omeprazole generally starts to work within 1 to 4 days, with many people feeling some relief from symptoms such as heartburn or acid reflux within 2 to 3 days. However, it may take up to 4 weeks for omeprazole to reach its full effectiveness and provide complete symptom relief. If there is no improvement after about two weeks, it is advised to consult a doctor, as adjustments may be needed. The duration can depend on the condition being treated, with longer use sometimes required for chronic conditions like GERD or ulcers.
