So I have been on anti-depressants for 15months now. i was on Citalopram to start off with and my dosage went up and down through the months. but now i have been put on these new meds... Mirtazapine 30mg So this is the issue, i have missed a period and was wondering if any one else has suffered from this side affect whilst on this medication. And before any one say, "are you pregnant"....I'm not. i've done a test... i've done a few lol and they have all come back negative. And god dam it, the longest 5minutes of my life. but any way that is important. i need to know if any one else has had missed periods or none at all whilst on Mirtazapine?? I need to make sure its not my body going crazy (along with my mind) I'm beginning to worry.
