If I'm not mistaken, there is 4mg of it in Coricidin C&C, which is probably what your friend is taking. In my less wise days, I once took 60 pills at once. So that was 240mg of it that didn't kill me, but I thought I was going to die. I would be more worried about the DXM than the chlorpheniramine maleate. This is dangerous stuff (DXM). The thought of it now makes me shudder. I cannot stress enough how damaging it can be to both your body and mind!! (well, not yours, but your friends).
