If you have rhinitis, you want to calm the inflammation in your nose’s mucus membranes. You’ll want a decongestant, like pseudoephedrine or phenylephrine. A decongestant will help reduce nasal tissue swelling.
If you’re dealing with allergies or a runny nose, you should look for an antihistamine, like diphenhydramine for nighttime use or non-drowsy fexofenadine.
Products containing pseudoephedrine can be found behind your pharmacist’s counter.
Use as directed.
