Can I combine antihistamine and decongestant for cold?

Patient: Can an antihistamine and a decongestant be taken at the same time

Doctor: Yes, antihistamine and decongestant combination may be used at the same time and work better together. Since the therape utic action of either group would combat the side effects of the other to some extent, the dosage of each drug can be adjusted depending on the desired effects and dose schedule for the treatment.
