Hi, I am 33 year old and have been on Pristiq 50mg for a month for anxiety and at first only had the really dry mouth and insomnia as I took the tablet at night but changed to the morning. 3 weeks ago I had a Implanon inserted as well.. since then I have noticed that my left arm will get stiff and my fingers get tingly and numb.. especially in the hours of taking Pristiq. Spoke to my pharmacist yesterday and she said that the tingling etc isn’t a common side effect but to speak to my doc which I will do next week. I’m wondering if anyone else has had similar problems, I know it takes a while for our bodies to get used to these kinds of drugs but I’m not sure if maybe it’s the Implanon and Pristiq both being new for me and just stick it out or if me and Pristiq just aren’t a match. I don’t have the tingly or numbness when I miss a tablet. Very weird!!
