<s>[INST] Im on citalopram 20mg and have been for about 2 months (2nd time of being on it) recently ive been forgetting to take it only every couple of days ill possibly forget 1. ive been feeling worse than ever these past few days despite things going well with friends and work i was wondering if the missed doses being the issue or if i needed to up the dose? i know i probably dont need to up the dose but i just want/need something to sort me out and get me back to normal as soon as possibly as im just exhausted with feeling so down. [/INST] His admire your concern. Citalopram is antidepressant and use to treat mood disorder. It has short half like of 21 hours. So it can be possible that if you do not take it for one or two days then it produces with Chat Doctor. Though it is not common but yes occur in some patients. For this you have to take it daily or add low dose benzodiazepine to prevent such feeling if you forget to take it. The dose is appropriate and no need to up the dose. So continue to take same medicines and get well soon. If needed then consult psychiatrist for further assistance. Thank you. </s>
