Just started Remeron(Mirtazapine) 15 mg a night for anxiety. 5 days after I started it, I developed a sore throat and flu feelings. Told my doctor and he said its more than likely a virus, and not from the medication. I have had the sore throat now 6 days, and it hasn't turned into anything else, and i just got checked for strep which was negative. The adverse severe side effects state sore throat, fever, flu like symptoms, etc... so ofcourse I am worried. If it were from the Remeron, would it have happened just after 5 days of taking it? My doctor is really waving it off
