I keep seeing posts on social about neuropsychiatric side-effects tied to Singulair (montelukast). I’ll admit up front: I haven’t dug into every study yet, but what really jumps off the screen is how many parents and patients say they were never warned that this drug has carried an FDA black-box warning since 2020 (and red-flag data were around as far back as 2008!).
Why do we still see these horror stories week after week?
A couple of questions for the community
Your Experience : Were you (or your child) prescribed Singulair or its generic without any mention of the black-box risk? How did you find out?
Side-Effects Timeline : If you noticed mood changes, anxiety, or worse, how quickly did your prescriber connect the dots?
Reminder: If anyone you know is on montelukast and shows any mental-health shifts, most guidelines now say stop immediately and contact a professional.
It’s past time we held the system to its own “do no harm” standard…patient safety shouldn’t be optional.
