The Dangers and Ineffectiveness of Antibiotics for Acne
Information on this Outdated and, at Best, Temporary Acne Treatment
The Essential Information
Antibiotics should only be used for a maximum of 3-6 months and they only work for about half of people with acne. When they do work at all, they provide only temporary relief. They do not dramatically clear the skin on their own, and must always be combined with other treatments. Perhaps even more concerning is the fact that antibiotics create strains of resistant bacteria that can then be spread from person to person. For all of these reasons, doctors are prescribing antibiotics for acne less than in previous decades.
Antibiotics have been a mainstay of acne treatment for decades, despite the fact that it is well known that they never completely clear acne and must always be administered alongside topical treatments.1-6 They should only be used for a maximum of 3 months and thus, even when they do help reduce acne, offer only temporary relief. Oral antibiotics help kill acne bacteria (P. acnes) in people who are not resistant to their effects and also help reduce inflammation.7-10 Topical antibiotics do not kill acne bacteria, but do help reduce inflammation.11Oral and topical antibiotics should never be used at the same time.
It has long been noted that antibiotics only work for about half of the population, and produce only moderate effectiveness.12 When they do help, they often only work for a short period of time. Acne tends to "get used to" both oral and topical antibiotic treatments and become resistant to it.7,13 It has become accepted practice that antibiotics must always be used in conjunction with other topical treatments because this helps reduce the chance for resistance, and because antibiotics do not work well enough on their own. As more research comes to light, it appears antibiotics are not helping clear acne as well as they once did. Researchers theorize this may be directly related to increased bacterial resistance across the population.13
A large study conducted by the British Journal of Dermatology studied 4274 acne patients and found that since 1991 an average of 51% of patients harbored colonies of resistant bacteria.14 Other studies have shown similar levels of antibiotic resistant acne bacteria.15-20 Interestingly, researchers are finding similar levels of resistance in both patients treated with antibiotics and those untreated as well, although those untreated have somewhat lower levels of resistance.21 This is because it is quite easy to pass antibiotic resistant strains of bacteria to people close to you.22
How Resistance Happens
On a microscopic level, geneticists and biologists are finding multiple possible reasons why this occurs. The first reason is gene mutation within a bacteria cell.8,23-25 Bacteria have also been observed banding together and producing biofilms, a coating which slows penetration of antibacterial medication.10
All antibiotics are well known to create resistant strains of bacteria, and these resistant strains of bacteria now colonize upwards of half of the population.26-27 However, antibiotics have side effects beyond creating resistant bacteria. Oral antibiotics have more side effects than topical antibiotics and commonly cause gastrointestinal disorders (diarrhea, nausea, stomach cramps) and skin reactions. Depending on which antibiotic is prescribed, neurological problems (dizziness, vertigo) and photosensitivity (increased sensitivity to the sun) are also common. Less frequent side effects include permanent bluish-gray discoloration of the skin, permanent yellow/gray/brown discoloration of teeth, and sudden outbreaks of acne. In rare cases, oral antibiotics can cause auto-immune diseases (i.e. lupus), irreversible hearing loss, and heart problems which can lead to death.22,28-31
Topical antibiotics have fewer side effects but can also be absorbed through the skin and into the body and cause gastrointestinal problems. Upon application, topical antibiotics commonly cause peeling, skin irritation, including redness, dryness, and burning.22,28
Neither oral nor topical antibiotics should be used while attempting to become pregnant, while pregnant, or while breast feeding unless specifically directed by a physician.28
What to Do about It
First, if your doctor attempts to prescribe antibiotics for your acne, ask her why she wants you to do this and if there are other options you can try instead. If you are prescribed antibiotics from a doctor, do not stop your course before speaking with her about it since this can make it more likely that you will create resistant strains of bacteria that will be with you for the rest of your life.
Also, keep in mind that benzoyl peroxide kills 99.9% of bacteria almost instantly and when used correctly will reliably and completely clear acne. It will never cause antibiotic resistance or the potential for systemic or long-term side effects and can be used for as long as you need to use it until you naturally grow out of acne.
If you have severe, widespread and deeply scarring acne, Accutane (isotretinoin) is also an option, but comes with severe and potentially long-term side effects and must be entered into carefully alongside a trusted physician.
I took oral and/or topical antibiotics for a year or so altogether during high school and college which is far longer than is prudent. Oral antibiotics did nothing for me and my skin did not improve nor get worse while on them. My skin worsened when I was put on clindamycin (clindamycin phosphate 1%), a topical antibiotic, but in retrospect this was likely because I stopped using benzoyl peroxide and instead started using clindamycin and sulfur, the two prescriptions my doctor wanted me to try. Antibiotics for me were like a bad joke - promising help but delivering nothing. It is more than likely that I now harbor colonies of resistant bacteria. Accutane cleared me up temporarily, but my acne returned post-Accutane. The Acne.org Regimen here at Acne.org finally got me cleared up for good."
