I have a cold, and have been on 75 mg sertraline for a little over 2 months. I took 30 mg of DayQuil about 6 hours ago, and just took another 15 mg now and Zoloft right after. Definitely should have looked up info before but I researched possible interactions and read a lot of stuff about serotonin syndrome and now I'm kind of freaking out. Is it okay that I took the DayQuil in small doses? I'm not going to take it again. cant tell if reading all this stuff is scaring me or if I should be worried.
