Okay so my doctor put me on celexa (citalopram) with my percocet and i'm scared to take it. because i've heard of people having crazy thoughts should i be concerne?

Not too much concern: Those two drugs have very different mechanisms of action and should have different effects on you.The Celexa, (citalopram)over time,should help with any depression/anxiety issues you may be experiencing and shouldn't cause you to have "crazy thoughts."If anything it should help organize thoughts better.The Percocet sometimes alters people's mentation but I don't think taking them together will make that worse.
