Antibiotic Treatment
I. Definition:
Antibiotics are generally very safe. They are
most commonly used to treat acne, but some other skin disorders, such as rosacea, skin
infections and perioral dermatitis, also respond to antibiotic treatment. Since
antibiotics do not cure, but only suppresses most of these skin disorders, it may be
necessary to continue taking them for months or even years.
II. Action:
- There is a bacteria that normally lives on the
skin called Propionibacterium acnes. This bacteria feeds on the sebum produced by
the skin's oil glands. Sometimes, this bacteria multiplies and causes inflammation and
skin disease. Antibiotics reduce the number of these bacteria.
III. Side effects:
- Out of countless women using oral contraceptives
who have taken antibiotics, a few have become pregnant. It is debatable as to whether the
failure of the contraceptive is due to the antibiotic or the established 1.0% failure rate
of the pill. Some experts recommend that women on antibiotic treatment use a second method
of birth control in addition to oral contraceptives if trying to avoid pregnancy while on
antibiotic treatment.
- Tetracycline, doxycycline, and minocycline make
you more sensitive to sunlight. In other words, it is easier to get a sunburn while taking
these medications, so you should use a sunscreen of SPF 15 or higher if the doctor
prescribed one of these antibiotics.
- Ten percent of female patients will develop a
yeast infection while taking antibiotics. The onset of genital itching and vaginal
discharge suggests the beginning of a yeast infection. If this occurs, call your
dermatologist and he will prescribe treatment. The antibiotic may be continued. It is
thought that eating yogurt two to three times a week will help prevent yeast infections.
- If you find out you are pregnant, call the doctor
immediately and stop the antibiotic treatment. If you are trying to get pregnant
antibiotics should not be used for most skin disorders.
- Many antibiotics cause temporary nausea and
abdominal cramps. If diarrhea or vomiting occurs, you should stop the medication and call
your dermatologist.
- Any antibiotic can cause an allergic reaction. If
you have had an antibiotic reaction be sure to tell the doctor. Allergic reactions can
range from harmless skin rashes to very serious breathing difficulties. If think you are
having an allergic reaction to your antibiotic call the doctor immediately.
IV. Safety:
- Most antibiotics are very safe when used as
prescribed by your physician.
V. How to use:
- Tetracycline should be taken with water on an
empty stomach, either 1 hour before meals or 2 hours after meals. You should not
take it with milk or dairy products because this will decrease the absorption of the
medicine.
- Do not take tetracycline
with iron, calcium or antacids. You should wait at least 2 hours before taking tetracycline if you must take one of these medicines or
vitamins.
- Do not take tetracycline
if you are nursing an infant, if you are under 8 years old, or if your are taking
barbiturates, lithium or phenytoin (Dilantin).
- Erythromycin, doxycycline, and minocycline should
all be taken with food. This will decrease the chances of developing an upset stomach.
Doxycycline and minocycline should not be taken with dairy products.
- Erythromycin should not be taken if you are on
Seldane, theophylline, or blood thinners such as Coumadin.
- It takes 4-6 weeks before you will see significant
results while taking antibiotic treatment for most skin conditions. It takes 2-3 months to
get the full effect of the medicine, so be patient.
