Drinking lots of water is key to thinning mucus. It makes it easier to get rid of. Drinking water, herbal teas, and clear broths keeps your body balanced.

Antihistamines are great for allergy-related post nasal drip. They stop histamine, a chemical that causes allergy symptoms. Common antihistamines like diphenhydramine and loratadine are found in most pharmacies and help reduce nasal secretions.
