I have started experiencing pain and stiffness in my lower back few days ago. I took naprocen, one tablet, and 4 hours later another one because pain persisted. As it is otc, I guess that it can not have serious side effects. What dose of naprocen is recommended in this type of pain?
Although it is otc, it is not safe to take it as you like it. There are instructions on the label of each otc that should be followed. Maximal dose of naproxen that should be used is 250-500mg twice daily. It is also recommended not to take it for longer then 10 days. So, if your pain in back keeps persistent, visit your doctor and ask for another way for pain management.
