To rid the body of nasal drainage and excess mucus quickly, rinse out the nose with a saltwater solution, also known as nasal irrigation, twice each day, according to ABC News. A combination of medical treatments and home remedies also provide cures for sinus drainage stemming from acute or chronic sinusitis, explains WebMD. Treatments for bacterial infections causing sinus drainage include antibiotics and over-the-counter decongestants to eliminate the infection and reduce mucus from developing in the sinuses.
Sinus drainage stemming from allergies is treated with antihistamines or allergy shots to desensitize the patient's sensitivity to the known allergen. People with sinus drainage that leads to swelling within the sinus membranes are commonly treated with steroids. Chronic sinusitis can also be treated with surgery to enlarge the sinus passages or remove blockages that are causing infections and excess drainage.
Nonsteroidal anti-inflammatory drugs help reduce pain and discomfort associated with sinus drainage but may not serve as a cure for the underlying medical condition causing the drainage, according to WebMD.
Patients should drink plenty of fluids to thin the mucus and rest to give the body time to recover from an infection causing sinus drainage, recommends WebMD. Install a humidifier in the home, and breath steam vapors to minimize swelling of the nasal passages and reduce congestion that accompanies drainage.
