Acne Antibiotic Treatments
Oral Antibiotics
Although acne is not an infection, the bacterial organism
Proplonobacterium acnes, as you learned in Chapter 3, is nevertheless
believed to play an important role in acne development. These bacteria
are responsible for breaking down and converting the oils and debris
trapped within clogged pores into irritating, acne-causing fatty acids.
Both oral and topical antibiotics effectively suppress these bacteria.
Antibiotics are a mainstay of acne therapy. At one time, only oral
antibiotics were available. Tetracycline has been a favorite for over
thirty years. Erythromycin and minocycline are two other frequently
prescribed oral antibiotics. However, since the introduction of topical
antibiotics, oral antibiotics are now more frequently reserved for
treating the most severe forms of acne.
When used to treat infections, oral antibiotics usually begin to work in
a matter of hours. In treating acne, however, oral antibiotics usually
do not bring about improvement for about three weeks.
Fortunately, the three oral antibiotics most commonly
prescribed-tetracycline, erythromycin, and minocycline-have proven
themselves generally safe even for long-term use. Minor, and often
temporary, side effects include upset stomach, diarrhea, headache, and
vaginal yeast infections. Your doctor is best able to choose the right
oral antibiotic for your condition and may even switch you from one to
the other, depending upon your response to treatment. Some of the more
common brands of oral antibiotics prescribed include Achromycin
(tetracycline), Erythrocin, EES-400, and Eryc capsules (erythromycin),
and Minocin (minocycline).
