What medicine is good for a sinus infection?

Sinus infections are best and most often treated with prescription antibiotics, according to the National Institute of Allergies and Infectious Diseases. This is because most sinus infections are bacterial. However, some sinus infections are viral or fungal and require other medications, according to WebMD.

According to Care2.com, using a neti pot helps clear sinuses that are irritated by a sinus infection. The neti pot flushes out any allergens or debris causing nasal irritation. A neti pot looks like a miniature tea pot and is filled with a warm saline solution. The solution is poured into one nasal passage with a tilted head, and the solution then drains out through the other passage.
