Been on Cipralex for a week then stopped and having difficulty passing urine with low stream, it hurts and is very painful. How long will this last?

See below. Cipralex (Escitalopram) is an antidepressant of the "selective serotonin reuptake inhibitor (SSRI)" class. This class of drugs has been associated with difficulty voiding and urinary retention. If such is the case, it could take several days before improving. Since you're having significant pain, possible UTI or severe retention that may require antibiotics or catheterization. Recommend contact MD.
