What is an otc medicine that dries up mucus in the sinuses? I'm not allergic to any medibations

Not medical advice: An antihistamine is used to dry up excess fluid in the sinuses and can also treat allergies. Side effects of an antihistamine include drowsiness, dizziness, headache, and upset stomach. You should ask your doctor if you have high blood pressure, heart disease, stomach ulcers, or if you are pregnant or breastfeeding as it can be secreted in breast milk.
