What medications promote drainage?

Home remedies that open and hydrate the sinuses may promote drainage. See Home Remedies section for information on increasing daily fluid intake, inhaling steam, taking expectorants and pain relievers, and nasal saline irrigation.

If environmental allergies cause sinusitis, an antihistamine may help reduce swelling of the mucous membranes. Allergens stimulate white blood cells in the blood and tissues to release histamine into the circulation. This causes fluid to leak from blood vessels into the tissues of the nasal passageways, leading to nasal congestion.
