Use saline nasal spray
Do a saline rinse with a neti pot or squeeze bottle (use distilled, sterile, or previously boiled and cooled water)
Take a steamy shower or breathe in steam from a bowl of hot water
Apply a warm compress to the face and around the nose
Use a humidifier in the room
Stay hydrated and drink warm fluids
Try gentle nasal blowing and clearing
Sleep with your head elevated
Use an over-the-counter decongestant nasal spray (oxymetazoline or similar) for up to 3 days
Use an over-the-counter oral decongestant (if safe for you) such as pseudoephedrine or phenylephrine
Use an over-the-counter antihistamine if allergies are likely (e.g., cetirizine, loratadine, fexofenadine)
Use an over-the-counter steroid nasal spray for allergy-related congestion (e.g., fluticasone, mometasone)
Avoid smoking and strong irritants
Consider allergy triggers and reduce exposure (dust, pollen, pet dander)
Seek urgent care if you have severe facial pain, high fever, swelling around the eyes, trouble breathing, or symptoms after a serious injury
See a clinician if congestion lasts more than 10 days, keeps worsening, or is accompanied by thick/discolored discharge and significant facial pain
Stop and get medical advice if you have frequent nosebleeds or severe headache after using decongestant sprays
