I have been giving regular doses of ibuprofen to my son for the last two days because of throat inflamation, headaches, fever, etc. Twice, however, he has gotten really frantic and started acting paranoid, seeing things that weren't there. The second time he said he heard my voice in his head, and that his brain was "rushing" way too fast. Both episodes passed in a few minutes. I read that "pseudopsychosis" was a potential side effect of ibuprofen, and am wondering if these episodes will pass, or if I need to do something more than wait.
