Care Advice for a Sty

What You Should Know About a Sty:

  • A sty is a minor infection of an eyelash.
  • A sty usually comes to a head and forms a pimple in 3 to 5 days.
  • Most often, it drains and heals in a few more days.
  • Most styes can be treated at home.
  • Here is some care advice that should help.

Apply Heat to Bring to a Head:

  • Put a warm, wet washcloth to the eye. Do this for 10 minutes 3 times a day. Reason: this helps the sty come to a head.
  • Continue the warm wet cloth even after the sty begins to drain. Reason: to help remove the discharge and heal the sty.
  • Caution: do not rub the eye. Reason: rubbing can cause more styes.

Open the Pimple:

  • Age limit: your child is over 5 years old and cooperative.
  • When the center of the sty becomes yellow, you can open it. Do this by using tweezers. Pull out the eyelash that goes through the pimple. This will start drainage and healing.
  • Another option is to wait for drainage to start on its own. Most often, this occurs in another 1-2 days.
  • Caution: do not squeeze the red lump. Reason: this can cause an eyelid infection.

Antibiotic Eye Medicine:

  • Most single styes respond to the treatment with heat. They don't need prescription antibiotic eyedrops.
  • If there is more than one sty, your child may need antibiotic eyedrops. Also, antibiotics may be needed if styes keep coming back. This usually happens to children who rub their eyes often.

Contact Lenses:

  • Children who wear contact lenses need to switch to glasses until the sty heals.
  • Reason: to prevent damage to the cornea.
  • Disinfect the contacts before wearing them again.
  • Discard them if they are disposable.

What to Expect:

  • A sty usually comes to a head and forms a pimple in 3 to 5 days.
  • Most often, it drains and heals in a few more days.

Return to School:

  • Children with a sty usually do not need to miss any school.

Call Your Doctor If:

  • Eyelid gets red or swollen
  • Sty comes to a head, but does not drain by 3 days
  • More styes occur
  • Sty is not gone by 10 days
  • You think your child needs to be seen
  • Your child becomes worse

There are cases of measles in NC, and we are aware of exposures in Chapel Hill, Durham, and Wake County. We can give the MMR dose early to families who want it. This applies to infants 6-12 months who have not gotten a dose yet or kids under 4-5 years who have not gotten their second MMR dose. At this time, the NC DHHS and health departments are not recommending this unless traveling or living in an area with sustained transmission. 2 doses of the MMR vaccine are highly effective (97%) at preventing measles infections. At CHCAC, children receive their first dose at 12 months of age and a second dose at 4 years of age, ensuring they are fully protected as soon as possible, in accordance with the most up-to-date AAP recommendations. Some infants aged 6 months to 11 months who travel internationally or in high-prevalence areas may need a dose to protect them; however, they still require the 1-year and 4-year-old doses as well. If you are ever concerned about a possible exposure to measles, please CALL before entering our office. DO NOT ENTER the office. NC DHHS keeps a list of areas with measles exposures here . This is a highly contagious illness, and special precautions must be taken to prevent spread. The virus can be present in the air for 2 hours after an infected person is in the room, and 90% of susceptible patients can be infected. As always, if you have questions, we are here to help make sense of it all!
