Why this happens

Both drugs can reduce the production of prostaglandins, which are natural chemicals that help protect the lining of the stomach and maintain blood flow to the kidneys. When used together, their effects on the kidneys can be additive, potentially leading to reduced kidney function or fluid retention.

Ensure you stay well-hydrated by drinking plenty of water. If you notice swelling in your ankles, a significant change in how often you urinate, or severe stomach pain, contact your doctor immediately.
