There are many topical antibiotics available for the treatment of acne. Topical antibiotics are frequently a part of treatment regimens for all types of acne symptoms (Acne Types: 1-4). Most of the antibiotics are well tolerated, are minimally irritating and have few other side effects. Because you apply the treatment directly to the skin, you avoid the most common problem with oral antibiotic use, gastro-intestinal problems (e.g. upset stomach). For mild to moderate acne, topical antibiotics can provide some relatively quick improvement in acne sypmtoms.
Like oral antibiotics, topical antibiotics treat acne by inhibiting the growth of bacteria in the skin that triggers the inflammation associated with pimples. Unfortunately, topical antibiotics have two major drawbacks. First, the majority of people report that most of these treatments lose effectiveness over time, eventually to the point where it makes no real difference. Second, most topical antibiotics do not penetrate deeply into the skin. As a result, the use of topical antibiotics alone is generally insufficient for patients suffering from inflammatory acne (Acne Types: 3-4).

The scores listed by each medication represent their composite score on a Scale of 1 (worst) to 5 (best). The composite score is calculated by combining individual scores from several categories: Antibiotic Susceptibility (Scientific Reports), Effectiveness (User Reported) and Side Effects (User Reported).

Type of Treatment:Rx Medication – Antibiotic (Oral and Topical) - Lincosamide Family Official Name: Clindamycin Popular Brand Names: Cleocin, Dalacin, Duac (Clindamycin and Benzoyl Peroxide) and Zindaclin. Related Medications: Lincomycin, Novobiocin, Erythromycin, Azithromycin, Clarithromycin.
Clindamycin is a lincosamide family antibiotic that is a popular topical acne treatment. It commonly comes packaged alone or mixed with benzoyl peroxide. This antibiotic generally has a mild side effect profile when used topically. Clindamycin can be very effective, but clindamycin resistant bacteria are a growing problem in many counries.
One of the original oral antibiotics used to treat cystic acne, dapsone fell out of favor after the development of isotretinoin (Accutane). Recently, dapsone has been reformulated and FDA approved as a topical gel for the treatment of acne. The efficacy of topical dapsone is still being established. Dapsone has both antibacterial properties, and anti-inflammatory properties, which may be helpful in the treatment of inflammatory acne.
Type of Treatment:Rx Medication – Antibiotic (Oral and Topical) - Macrolide Family Official Name: Erythromycin Popular Brand Names: Aknemycin, E-Mycin, Benzamycin (erythromycin and Benzoyl Peroxide), Stiemycin and Eryacne. Related Medications: Azithromycin, Clarithromycin, Roxithromycin, Tylosin, Clindamycin.
Like clindamycin, erythromycin is a commonly prescribed topical treatment for acne, and often comes packaged alone or with benzoyl peroxide. Unfortunately, the majority of acne associated P. acnes bacteria in the United States and Europe are resistant to erythromycin.
Fusidic acid is a topical antibiotic that inhibits bacterial growth by preventing bacterial protein synthesis. Originally developed and marketed in the 60′s, fusidic has garnered renewed interest because of the emergence of widespread bacterial resistance to many common antibiotics. While fusidic acid is available in many countries, it is not approved for sale in the United States. Based on user reports, fusidic acid has a medium efficacy profile in the treatment of acne. It can be combined with many other medications, but it is not recommended for long term use.
Metronidazole (Metrogel) is commonly used as a treatment for Rosacea and other skin diseases. Metronidazole is also occasionally prescribed for the treatment of acne vulgaris. However, metronidazole tends to be an ineffective acne treatment. Propionibacterium acnes, the bacteria most commonly associated with acne vulgaris, is naturally resistant to metronidazole. .
Mupirocin is a well reviewed topical acne treatment that is composed of a mixture of pseudomonic acids, which were originally isolated from a bacteria, Pseudomonas fluorescens. It acts by inhibiting protein and RNA synthesis in susceptible bacteria. Many patients using mupirocin for the treatment of acne report favorable results during initial use, but notice a relatively rapid decrease in efficacy. This may be due to the fact that resistance to this class of antibiotic is relatively easily aquired by the target bacteria. Most strains Propionibacterium acnes are naturally resistant to mupirocin.
Type of Treatment:Rx Medication – Antibiotic (Topical) - Quinolone Family Official Name: Nadifloxacin. Popular Brand Names: Acuatim, Nadixa, Nadixin, Nadiflox and Nadoxin. Related Medications: Ciprofloxacin, Moxifloxacin, Ofloxacin, Levofloxacin, Norfloxacin, Sparfloxacin, Gatifloxacin.
Nadifloxacin is topical fluoroquinolone antibiotic that has been recently studied for its effectiveness in the treatment of acne. Nadifloxacin, a relative of the more common fluoroquinolone ciprofloxacin, is a broad spectrum antibiotic. Recent research has shown that nadifloxacin may be more effective at penetrating deep into the tissue than other topical antibiotics, making it a useful treatment for nodular and cystic acne. As a relatively new treatment for acne, nadifloxacin is not commonly prescribed by dermatologists and is not widely available.
Neomycin, bacitracin and polymixin B are commonly combined and sold as a topical antibacterial gel. The most common form of this medication is the popular OTC medication – Neosporin. Neosporin is commonly used to prevent infections in minor wounds and to accelerate healing. Neosporin is also occasionally used by acne patients as a spot treatment for pimples. However, there is little evidence that neosporin is an effective acne treatment (although it may be helpful to accelerate healing after popping a pimple).
Retapamulin is a recently approved member of the pleuromutilin family of antibiotics, a newly developed class of antibiotics. Like fusidic acid, retapamulin inhibits bacterial growth by preventing bacterial protein synthesis. Preliminary research has shown that Retapamulin is effective against a number of skin infections, including acne. It may be especially helpful in treating acne that fails to respond to more traditional antibiotic therapies.
Silver sulfadiazine is most commonly prescribed as a prophylactic antibiotic treatment to prevent infection in burn victims. It is also occasionally used in the treatment of acne. Silver sulfadiazine is a sulfa family antibiotic. It is poorly soluble and does not penetrate the skin well, making it poorly suited for use by those with nodular and cystic acne.
Type of Treatment:Rx Medication – Antibiotic (Topical) - Sulfa Family Official Name: Sulfacetamide. Popular Brand Names: Bleph, Cetamide, Clenia and Klaron. Related Medications: Sulfamethoxazole, Co-Trimoxazole, Silver Sulfadiazine, Dapsone, Sulfamylon.
Sulfacetamide is a sulfonamide family antibiotic that has shown good efficacy in the treatment of acne. Sulfacetamide commonly comes as a 10% solution packaged alone, or in combination with a 5% sulfur solution. Sulfur was one of the original treatmentsfor skin infections, with its use dating back to the ancient romans. Both sulfacetamide and sulfur have antibacterial properties, and sulfur itself is a keratolytic agent, which can help clear plugged pores.
Type of Treatment:Rx Medication – Antibiotic (Topical and Oral) - Tetracycline Family Official Name: Tetracycline. Popular Brand Names: Sumycin, Tetracap, Topicycline, Hostacyclin, Lupitetra. Related Medications: Doxycycline, Minocycline, Lymecycline, Oxytetracycline, (Tigecycline).
Topical tetracycline is available for the treatment of acne, but is rarely prescribed due to its poor efficacy and side effects profile.
