Can I take Lanzoprole and Naproxen together?

Why this happens

Lansoprazole increases the pH (reduces the acidity) of the stomach. Because naproxen needs a certain level of acidity to dissolve and be absorbed efficiently, the presence of lansoprazole can slightly alter its absorption profile. This is generally considered a 'beneficial' interaction because the protective effect on the stomach outweighs the minor change in drug absorption.

What you should do

It is safe and common to take these together. In fact, if you are taking naproxen long-term, your doctor likely prescribed lansoprazole specifically to prevent stomach ulcers. Take them exactly as directed by your healthcare professional. If you notice any unusual stomach pain or black, tarry stools, contact your doctor immediately.
