I'm feeling pretty woebegone with a nasty headcold, but when I stopped in at the druggist to pick up a cold remedy, the directions on most cautioned that they should not be taken by anyone who takes an MAO-I or "a Parkinson's medication." What does that mean, I wonder? I settled for chicken broth and Vicks vap-o-rub. I took an antihistamine that has been in the cupboard for a while (not very effective) and a couple ibuprofen. What do you all take for congestion and coughing?
