<s>[INST] I am naproxin 500mg (440mg) twice a day, 8 hours apart. This is for a fall I had yesterday. I fell backwards on my pelvic area and now have pain there and upper buttocks. I went to Urgent Care and have no fractures. The naproxin only decreases pain for 3 hours. I would like to take 600 mg of ibuprophen in between. How would I schedule the 2 medications? Thank you [/INST] Hello, You can safely take ibuprofen and naproxen together. Keep in mind that you may experience severe gastritis while combining the drugs together. You can take drugs pantoprazole to tackle gastritis related side effects. Hope I have answered your query. Let me know if I can assist you further.
