What is the preferred antibiotic for a stye that won't go away after a couple of weeks?

Primary aid is heat: Frequent warm compresses applied to the area involved will improve blood flow and hasten the localisation & drainage thru the outer or inner eyelid surface. An antibiotic drop or ointment with anti-staph activity like sulfacetamide, erythromucin or Bacitracin is applied at regular intervals. Failure to respond over a week or so may indicate need for incision & drainage.Ck with your dr.

Warm compresses: Warm compresses (wash cloth with hot water and hold it on the stye for 5-10 minutes, reheating as needed), or surgical incision and drainage, or steroid have been the only effective treatments demonstrated get rid of a stye. A stye is due to the orifice of an oil gland (mebomian gland) in the eyelid margin becoming inflamed, and not an infection, so antibiotics are not indicated.
