my son 16 years old. taking Prozac .was taken to the ER today (2,17,16). With uncontrollable shacking. head and neck bent over to one side. could talk and could tell me where he was and day of the week ect.... BP was 143 over 111. pulse 84 bpm. he was given demiral and then valium. catscan revealed nothing abnormal.. this went on for about 5 hours. is now resting at home asleep. No other meds or drugs involved!!! Could this be a reaction to the Prozac?
