how long does a stye last after you start the antibiotics in the eye

It all depends upon the severity. As you mentioned you started antibiotic eyedrops it should go within few days but if your eyelid infection persists or spreads beyond your eyelid, your doctor may recommend oral antibiotics. Pus-filled sty that won’t rupture or burst on its own has to lance and drain by your doctor to relieve pain and pressure.
