Suddenly stopping Citalopam can cause SSRI withdrawal syndrome
characterized by nausea, electric shock like feeling, sweating, insomnia, confusion, vertigo, trmor and nightmares. Binovum withdrawal can cause spotting, change in menstrual cycle, mood swings, weight gain etc.
Hope this helps. Please let me know if there is any thing else and do keep me posted. Take care!
