Constant dripping or runny nose? Stop the drip with the right antihistamines or decongestants.
Find the right medicineClear mucus can come from an irritated nose, but it doesn't rule out an infection. Green or yellow mucus shows that white blood cells have been fighting an infection, but antibiotics are rarely needed for a runny nose. See a doctor if only one nostril runs, as something may be stuck in it. Fluid or blood leaking from the nose after a head injury needs Triple Zero (000). Sneezing with itchy eyes points to hay fever or sneezing; a sore throat and aches to cold and flu; and pain in your face to sinus pain.
Some medicines, including anti-inflammatories, ACE inhibitors and some diuretics, can cause a runny nose. Decongestants can help a runny nose from a cold, but using them for more than a few days at a time can make symptoms worse. Antihistamines alone aren't effective for a cold but can ease allergy symptoms. A saltwater rinse can wash out mucus and allergens. Mucus running down the back of your throat (post-nasal drip) can cause a cough. See your doctor if a runny nose isn't improving, gets worse or comes with a high fever.
