Boils (Abscesses)
What is a boil?
A boil is a tender, red lump in the skin. It is painful
even when not being touched. Boils are usually 1/2 to 1
inch across.
What is the cause?
Boils are caused by a bacterial infection of a hair root or
skin pore. The bacteria that cause boils are called
Staphylococcus (also called staph bacteria).
How long does it last?
Without treatment, the body will fight off the infection.
After about a week, the center of the boil becomes soft and
mushy (filled with pus). The overlying skin then develops a
pimple or becomes thin and pale. The boil is now ready for
draining. Without lancing, it will drain by itself in 3 or
4 days. Until it drains, a boil is extremely painful.
How can I take care of my child?
- Antibiotics
Boils heal faster and are less likely to recur if your
child receives an antibiotic that kills staph bacteria.
Your child's antibiotic is __________________________.
Your child's dosage is _________ given _______ times a
day for _______ days.
- Lancing or draining the boil
In general, it's better not to open a boil on your own
child because it's a very painful procedure. Until the
boil comes to a head or becomes soft, apply warm
compresses 3 times a day for 20 minutes. When the boil
is ready, contact your child's health care provider.
Once opened, the boil will drain pus for 2 or 3 days and
then heal. Since the pus is contagious, the boil must be
covered by a large 4 x 4 inch gauze bandage and
tape. This bandage should be changed and the
area washed with an antiseptic soap 3 times a day.
- Prevention of more boils
Boils can become a recurrent problem. The staph
bacteria on the skin can be decreased by showering and
washing the hair daily with an antibacterial soap.
Showers are preferred because during a bath bacteria are
just moved to other parts of the skin.
- Contagiousness
The pus in boils is contagious. Make sure that other people in
your family do not use your child's towel or washcloth.
Any clothes, towels, or sheets that are contaminated with
drainage from the boils should be washed with Lysol. Any
bandages with pus on them should be carefully thrown
away.
- Common mistakes in the treatment of boils
Sometimes friends or relatives may advise you to squeeze
a boil until you get the core out. The pus in a boil
will come out easily if the opening is large enough.
Squeezing is not only very painful but also
carries the risk that bacteria will be forced into the
bloodstream. Squeezing can also cause other boils in the
same area. Squeezing boils on the face is dangerous.
When should I call my child's health care provider?
Call during office hours if:
- The boil is not better within 48 hours after starting the
antibiotic.
- The boil has come to a head and needs to be opened.
- You have other concerns or questions.
