In brief: Within 12 hours
If you stop the medication, sympoms of stomach upset should abate within 12 hours.
However, if you have been on the medicine for awhile and you develop abdominal complaints, it could be a sign of a more serious and persistent problem such as an ulcer or gastritis. Persistent discomfort should be assessed by your doctor.
