Hi, I have been on Pristiq 50mg. I went to a GP this morning as I have developed a swollen tongue to the point that I have teeth imprints on my tongue as Its too big. I also have diarrhoea, hot sweats, dizziness and last night I had muscle twitching, but that went away. I have stopped taking this drug, last pill was 7.30am yesterday. But I have noticed that the swelling has not gone down at all. Should I go back to doctors?
