There are two categories of medications to treat the different types of sinus congestion. They are known as antihistamines and decongestants.
Antihistamines are used for a runny nose. They help dry the sinus congestion and slow the drips. Antihistamines are also commonly used to treat seasonal allergies.
Decongestants are used for that stuffy, full feeling in your head. They reduce the swelling in your nasal passages which allows mucous to drain.
Many medications combine one of these decongestants or antihistamines with other medications to make multi-symptom treatments. They are sold under numerous brand names.
