⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Colitis: Clindamycin can cause severe colitis, which may result in death. Diarrhea, bloody diarrhea, and colitis (including pseudomembranous colitis) have been reported with the use of clindamycin. Neuac ® (clindamycin phosphate and benzoyl peroxide) Gel, 1.2%/5% should be discontinued if significant diarrhea occurs.
( 5.1 ) Ultraviolet light and environmental exposure (including use of tanning beds or sun lamps): Minimize sun exposure following drug application. ( 5.2 )
5.1Colitis Systemic absorption of clindamycin has been demonstrated following topical use of clindamycin. Diarrhea, bloody diarrhea, and colitis (including pseudomembranous colitis) have been reported with the use of topical and systemic clindamycin. If significant diarrhea occurs, Neuac ® (clindamycin phosphate and benzoyl peroxide) Gel, 1.2%/5% should be discontinued.
Severe colitis has occurred following oral and parenteral administration of clindamycin with an onset of up to several weeks following cessation of therapy. Antiperistaltic agents such as opiates and diphenoxylate with atropine may prolong and/or worsen severe colitis. Severe colitis may result in death.
Studies indicate a toxin(s) produced by Clostridia is one primary cause of antibiotic-associated colitis. The colitis is usually characterized by severe persistent diarrhea and severe abdominal cramps and may be associated with the passage of blood and mucus. Stool cultures for Clostridium difficile and stool assay for C. difficile toxin may be helpful diagnostically.
5.2Ultraviolet Light and Environmental Exposure Benzoyl peroxide, a component of Neuac ® (clindamycin phosphate and benzoyl peroxide) Gel, 1.2%/5%, may cause increased sensitivity to sunlight. Minimize sun exposure (including use of tanning beds or sun lamps) following drug application. [ See Nonclinical Toxicology (13.1) ] Patients who may be required to have considerable sun exposure due to occupation and those with inherent sensitivity to the sun should exercise particular caution.
🤒 Adverse Reactions ▾
6 ADVERSE REACTIONS The following adverse reaction is described in more detail in the Warnings and Precautions section of the label: Colitis [ see Warnings and Precautions (5.1) ]. The most common local adverse reactions (≥5%) are erythema, peeling, dryness, and burning. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Medimetriks Pharmaceuticals, Inc. at 973-882-7512 or the FDA at 1-800-FDA-1088 or www.fda.gov/medwatch .
6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared with rates in the clinical trials of another drug and may not reflect the rates observed in practice. During clinical trials, 397 subjects used clindamycin phosphate and benzoyl peroxide gel, 1.2%/5% once daily for 11 weeks for the treatment of moderate to moderately severe facial acne vulgaris. All subjects were graded for facial local skin reactions (erythema, peeling, burning, and dryness) on the following scale: 0 = absent, 1 = mild, 2 = moderate, and 3 = severe.
The percentage of subjects that had symptoms present before treatment (at baseline) and during treatment is presented in Table 1. Table 1. Local Skin Reactions With Use Of Clindamycin Phosphate and Benzoyl Peroxide Gel, 1.2%/5% Combined Results From Five Trials (n=397) % of Subjects Using Clindamycin Phosphate and Benzoyl Peroxide Gel, 1.2%/5% with Symptom Present Before Treatment (Baseline) During Treatment Symptom Mild Moderate Severe Mild Moderate Severe Erythema 28% 3% 0 26% 5% 0 Peeling 6% <1% 0 17% 2% 0 Burning 3% <1% 0 5% <1% 0 Dryness 6% <1% 0 15% 1% 0 (Percentages derived by number of subjects receiving clindamycin phosphate and benzoyl peroxide gel, 1.2%/5% with symptom score/number of enrolled subjects receiving clindamycin phosphate and benzoyl peroxide gel, 1.2%/5%).
6.2Postmarketing Experience The following adverse reactions have been identified during post approval use of clindamycin phosphate and benzoyl peroxide gel, 1.2%/5%. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Anaphylaxis, as well as allergic reactions leading to hospitalization, has been reported in postmarketing use with clindamycin phosphate and benzoyl peroxide gel, 1.2%/5%.
Urticaria, application site reactions, including discoloration have been reported.
🔄 Drug Interactions ▾
7 DRUG INTERACTIONS Neuac ® (clindamycin phosphate and benzoyl peroxide) Gel, 1.2%/5% should not be used in combination with erythromycin-containing products because of its clindamycin component. ( 7.1 )
7.1Erythromycin Avoid using Neuac ® (clindamycin phosphate and benzoyl peroxide) Gel, 1.2%/5% in combination with erythromycin-containing products due to its clindamycin component. In vitro studies have shown antagonism between erythromycin and clindamycin. The clinical significance of this in vitro antagonism is not known.

🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Clindamycin: Clindamycin is a lincosamide antibacterial [ see Clinical Pharmacology (12.4) ]. Benzoyl Peroxide: Benzoyl peroxide is an oxidizing agent with bacteriocidal and keratolytic effects, but the precise mechanism of action is unknown.
12.3Pharmacokinetics A comparative trial of the pharmacokinetics of clindamycin phosphate and benzoyl peroxide gel, 1.2%/5% and 1% clindamycin solution alone in 78 subjects indicated that mean plasma clindamycin levels during the 4-week dosing period were less than 0.5 ng/mL for both treatment groups. Benzoyl peroxide has been shown to be absorbed by the skin where it is converted to benzoic acid. Less than 2% of the dose enters systemic circulation as benzoic acid.
12.4Microbiology Clindamycin binds to the 50S ribosomal subunits of susceptible bacteria and prevents elongation of peptide chains by interfering with peptidyl transfer, thereby suppressing protein synthesis. In Vivo Activity: No microbiology studies were conducted in the clinical trials with this product. In Vitro Activity: The clindamycin and benzoyl peroxide components individually have been shown to have in vitro activity against Propionibacterium acnes , an organism which has been associated with acne vulgaris; however, the clinical significance of this in vitro activity is not known.
Drug Resistance: There are reports of an increase of P. acnes resistance to clindamycin in the treatment of acne. In patients with P. acnes resistant to clindamycin, the clindamycin component may provide no additional benefit beyond benzoyl peroxide alone.
