Ask a doctor or pharmacist before using any other cold, cough, allergy, or sleep medicine. Antihistamines and decongestants are contained in many combination medicines. Taking certain products together can cause you to get too much of a certain drug. Check the label to see if a medicine contains an antihistamine, decongestant, or cough suppressant.
