Stye ointment is a medicine that is used in treating a stye, an eye infection that affects the sebaceous gland along the lash line. The condition starts as a red painful lump that becomes filled with a yellow or clear fluid after about 3 days.
There are different stye ointments in the market that are used in treating the condition. Non-prescription drugs cannot be used in treating styes, according to Stye.com. The ointment usually helps to relieve the symptoms of stye, such as burning, itching and stinging. A stye is usually caused by a combination of bacteria and a blocked oil gland, according to WebMD.
