Hi there, I was given a prescription for Citalopram 20mg. I took my first one Friday night at 9pm and everything was fine until 9am the next morning when I was hit with diarrhea and horrible neusea and increased heat and sweating. I did go to an emergency doctor who said he could give me nothing for the neusea as there was a slight possibility that I could get convulsions from the interaction of the two drugs and that I will just have to ride it out. It is now Sunday 6:30am and most of the symptoms have subsided but I have had no food and minimal water as this upset my stomach. I seem to be ok drinking water this morning. I still have a horrible headache and was wondering if it is safe to take a Paracetamol Osteo 675mg for the headache? It is the only painkiller I have in the house. Oh FYI I have decided not to continue taking the Citalopram, its just not worth it. Also, how long until this drug is out of my system?
