I have had lower back pain for the past day. I took 4 ibuprofen yesterday afternoon. I began to notice I was feeling depressed and overwhelmed- crying endlessly for no apparent reason. I have gone from extreme anger to extreme depression. Again this morning, my back pain was unbearable so I took 3 more ibuprofen this morning.

My question is, can ibuprofen cause depression and/or psychosis? Thanks!
