My father was put on vyvanse 20mg about a year ago and his doctor has switched him to 70mg about a month ago. Please keep in mind my father has always been strange like into conspiracy theories, the end of the world stuff. Two days ago I received an alarming text from him at 4am (he barley sleeps) saying he can't go home and he needs help. He told me to be careful. Then he went missing. To sum up the story he believes that drug dealers are after him (they supply crack cocaine to someone that lives in his building) he says they chased him in their suburbans and faught him (he has no marks) he refuses to go back to his apartment because he believes they are trying to kill him. I called the police who advised me to get a mental assessment but I don't want to pass my father off as crazy. Are delusions and paranoia associated with this drug?
