What are antihistamines and how can they help with clearing a stuffed-up nose?

ANSWER

You may need this type of medicine if your nose is stuffy because of allergies. Histamines are chemicals in your body that cause allergic symptoms, including a stuffy nose. Antihistamines help prevent allergic reactions by blocking these chemicals.

Some of these meds can make you sleepy, so read the label. They work best if you take them before your allergies begin, but they can work after the fact, too.
