I was told Halls Fruit Breezers were ok for sore throat, since they don't have menthol. Or if you don't want to take those, hard candy, tea with honey, warm or cool washcloth on your throat/head/face...wherever feels best. Tylenol for pain. Humidifier, plain saline nasal spray, or warm baths/showers for congestion.
I was told no pseudofed when I was sick, but that was first tri, so maybe in second tri it is ok...just make sure you check with your dr.
