I have a cold, and i used afrin nasal spray. i sniffled up after using it, & i felt some driplets go into my lungs, from my nostrils. is this bad?

This side effect: from nasal sprays is expected and does not cause problems. The constituents in Afrin and other nasal sprays do not cause lung inflammation or infection, similar to the constituents used in inhalers. As, or more often, people swallow excess Afrin which is more of a problem. Follow administration directions explicitly, especially not taking for more than a few days at a time. You can be "hooked."
