Did sertraline stop working for anyone?

[Metalhead]

I’ve been on sertraline for about 2 years for PMDD. Initially I felt much better, then the effects seemed to wear off a bit but I still felt mostly ok, but the last couple of months I’ve really struggled and don’t feel like I’m getting any benefits from it anymore. Has this happened to anyone else? Do I need to increase the dose or switch to a different medication?

Yes. Me.

After a few years. Switched to Citalopram which is much better for me and still works after 7 years

Thanks raccoon, maybe a trip to the GP is in order then.
