Can zoloft (sertraline) cause narcolepsy? i've been taking it for awhile but recently have had day sleeping. falling asleep for few secs repeatedly.

Not cause: If you have narcolepsy, it is NOT caused by Zoloft, (sertraline) but since a major adverse reaction from this drug is drowsiness, this may explain a significant bad reaction. Could discuss with doctor, stop for a few days and see if things improve.

Sleepiness: Zoloft (sertraline) is unlikely to cause sleepiness. You should evaluate your sleep habits and maintain a regular sleep pattern. Make a virtual apt to discuss your condition in detail in the mean time follow sleep hygiene protocols.I hope that was helpful.
