What kind of pills or treatment can somebody get for eyelid swelling?

Depends: Eyelid swelling can be indicative of numerous conditions. It could be as benign as a chalazion (stye) or as serious as orbital cellulitis. It is important to seek the care of an ophthalmologist if there is any pain with eye movement, decrease in vision, or persistent swelling that doesn't improve.

Depends on the cause: Eyelids can swell from allergies, masses, infections and injury. Treatment for the swelling is directed at the specific cause. Since eyelid infections are serious and can lead to severe vision loss and worse, any swelling should be evaluated by an eye doctor.
