Interactions between your drugs
lansoprazole gefitinib
Applies to: Prevacid NapraPAC 500 (lansoprazole / naproxen) and gefitinib
By reducing the acidity level in the stomach, medications like lansoprazole may interfere with the absorption of gefitinib into the bloodstream and reduce its effectiveness. It is generally best to avoid using these medications together when possible. However, if you have no other alternatives for treatment, it is recommended that you take gefitinib 12 hours before or 12 hours after lansoprazole to help minimize the impact of the interaction. Talk to your doctor or pharmacist if you have any questions or concerns. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
naproxen lansoprazole
Applies to: Prevacid NapraPAC 500 (lansoprazole / naproxen) and Prevacid NapraPAC 500 (lansoprazole / naproxen)
Talk to your doctor before using naproxen together with lansoprazole. Using these medications together may affect the enteric coating of naproxen, causing the medication to be released too early in the body. This can make naproxen less effective. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
