⚠️ 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. ZIANA Gel should be discontinued if significant diarrhea occurs. ( 5.1 ) • Ultraviolet Light and Environmental Exposures: Avoid exposure to sunlight and sunlamps. Wear sunscreen daily. ( 5.2 )
5.1Colitis Systemic absorption of clindamycin has been demonstrated following topical use of this product. Diarrhea, bloody diarrhea, and colitis (including pseudomembranous colitis) have been reported with the use of topical clindamycin. When significant diarrhea occurs, ZIANA Gel should be discontinued.
Severe colitis has occurred following oral or 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 Exposure to sunlight, including sunlamps, should be avoided during the use of ZIANA Gel, and patients with sunburn should be advised not to use the product until fully recovered because of heightened susceptibility to sunlight as a result of the use of tretinoin.

Daily use of sunscreen products and protective apparel (e.g., a hat) are recommended.
Weather extremes, such as wind or cold, also may be irritating to patients under treatment with ZIANA Gel.
🤒 Adverse Reactions ▾
6 ADVERSE REACTIONS Observed local adverse reactions in patients treated with ZIANA Gel were skin erythema, scaling, itching, burning, and stinging. Other most commonly reported adverse events (≥1% in patients treated with ZIANA Gel) were nasopharyngitis, pharyngolaryngeal pain, dry skin, cough, and sinusitis. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Bausch Health US, LLC at 1-800-321-4576 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch
6.1Clinical Studies Experience Because clinical trials are conducted under prescribed conditions, adverse reaction rates observed in the clinical trial may not reflect the rates observed in practice. The adverse reaction information from clinical trials does, however, provide a basis for identifying the adverse reactions that appear to be related to drug use for approximating rates. The safety data presented in Table 1 (below) reflects exposure to ZIANA Gel in 1853 patients with acne vulgaris.
Patients were 12 years and older and were treated once daily for 12 weeks. Adverse reactions that were reported in ≥1% of patients treated with ZIANA Gel were compared to adverse reactions in patients treated with clindamycin phosphate 1.2% in vehicle gel, tretinoin 0.025% in vehicle gel, and the vehicle gel alone: Table 1: Adverse Reactions Reported in at Least 1% of Patients Treated with ZIANA Gel: 12-Week Studies ZIANA Gel N=1853 N (%) Clindamycin N=1428 N (%) Tretinoin N=846 N (%) Vehicle N=423 N (%) PATIENTS WITH AT LEAST ONE AR 497 (27) 342 (24) 225 (27) 91 (22) Nasopharyngitis 65 (4) 64 (5) 16 (2) 5 (1) Pharyngolaryngeal pain 29 (2) 18 (1) 5 (1) 7 (2) Dry skin 23 (1) 7 (1) 3 (<1) 0 (0) Cough 19 (1) 21 (2) 9 (1) 2 (1) Sinusitis 19 (1) 19 (1) 15 (2) 4 (1) NOTE: Formulations used in all treatment arms were in the ZIANA vehicle gel.
Cutaneous safety and tolerance evaluations were conducted at each study visit in all of the clinical trials by assessment of erythema, scaling, itching, burning, and stinging: Table 2: ZIANA Gel-Treated Patients with Local Skin Reactions Local Reaction Baseline N=1835 N (%) End of Treatment N=1614 N (%) Erythema 636 (35) 416 (26) Scaling 237 (13) 280 (17) Itching 189 (10) 70 (4) Burning 38 (2) 56 (4) Stinging 33 (2) 27 (2) At each study visit, application site reactions on a scale of 0 (none), 1 (mild), 2 (moderate), and 3 (severe), and the mean scores were calculated for each of the local skin reactions.
In Studies 1 and 2, 1277 subjects enrolled with moderate to severe acne, 854 subjects treated with ZIANA Gel and 423 treated with vehicle. Analysis over the 12-week period demonstrated that cutaneous irritation scores for erythema, scaling, itching, burning, and stinging peaked at 2 weeks of therapy, and were slightly higher for the ZIANA-treated group, decreasing thereafter. One open-label 12-month safety study for ZIANA Gel showed a similar adverse reaction profile as seen in the 12-week studies.
Eighteen out of 442 subjects (4%) reported gastrointestinal symptoms.
🔄 Drug Interactions ▾
7 DRUG INTERACTIONS • Concomitant use of topical medications with a strong drying effect can increase skin irritation. Use with caution. ( 7.1 ) • ZIANA Gel should not be used in combination with erythromycin-containing products because of its clindamycin component. ( 7.2 )
7.1Concomitant Topical Medication Concomitant topical medication, medicated or abrasive soaps and cleansers, soaps and cosmetics that have a strong drying effect, and products with high concentrations of alcohol, astringents, spices or lime should be used with caution. When used with ZIANA Gel, there may be increased skin irritation.
7.2Erythromycin ZIANA Gel should not be used in combination with erythromycin-containing products due to its clindamycin component. In vitro studies have shown antagonism between these two antimicrobials. The clinical significance of this in vitro antagonism is not known.
7.3Neuromuscular Blocking Agents Clindamycin has been shown to have neuromuscular blocking properties that may enhance the action of other neuromuscular blocking agents. Therefore, ZIANA Gel should be used with caution in patients receiving such agents.
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS
8.1Pregnancy Pregnancy Category C. There are no well-controlled trials in pregnant women treated with ZIANA Gel. ZIANA Gel should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
ZIANA Gel was tested for maternal and developmental toxicity in New Zealand White Rabbits with topical doses of 60, 180 and 600 mg/kg/day. ZIANA Gel at 600 mg/kg/day (approximately 12 times the recommended clinical dose assuming 100% absorption and based on body surface area comparison) was considered to be the no-observed-adverse-effect level (NOAEL) for maternal and developmental toxicity following dermal administration of ZIANA Gel for 2 weeks prior to artificial insemination and continuing until gestation day 18, inclusive.
For purposes of comparisons of the animal exposure to human exposure, the recommended clinical dose is defined as 1 g of ZIANA Gel applied daily to a 60 kg person. Clindamycin Teratology (Segment II) studies using clindamycin were performed orally in rats (up to 600 mg/kg/day) and mice (up to 100 mg/kg/day) (583 and 49 times amount of clindamycin in the recommended clinical dose based on body surface area comparison, respectively) or with subcutaneous doses of clindamycin up to 180 mg/kg/day (175 and 88 times the amount of clindamycin in the recommended clinical dose based on body surface area comparison, respectively) revealed no evidence of teratogenicity.
Tretinoin In oral Segment III studies in rats with tretinoin, decreased survival of neonates and growth retardation were observed at doses in excess of 2 mg/kg/day (~78 times the recommended clinical dose assuming 100% absorption and based on body surface area comparison). With widespread use of any drug, a small number of birth defect reports associated temporally with the administration of the drug would be expected by chance alone. Thirty cases of temporally associated congenital malformations have been reported during two decades of clinical use of another formulation of topical tretinoin.
Although no definite pattern of teratogenicity and no causal association have been established from these cases, five of the reports describe the rare birth defect category, holoprosencephaly (defects associated with incomplete midline development of the forebrain). The significance of these spontaneous reports in terms of risk to the fetus is not known. Dermal tretinoin has been shown to be fetotoxic in rabbits when administered in doses 40 times the recommended human clinical dose based on body surface area comparison.
Oral tretinoin has been shown to be fetotoxic in rats when administered in doses 78 times the recommended clinical dose based on body surface area comparison.
8.3Nursing Mothers It is not known whether clindamycin is excreted in human milk following use of ZIANA Gel. However, orally and parenterally administered clindamycin has been reported to appear in breast milk. Because of the potential for serious adverse reactions in nursing infants, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.
It is not known whether tretinoin is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when ZIANA Gel is administered to a nursing woman.
8.4Pediatric Use Safety and effectiveness of ZIANA Gel in pediatric patients under the age of 12 have not been established. Clinical trials of ZIANA Gel included patients 12-17 years of age. [See Clinical Studies (14) .]
8.5Geriatric Use Clinical studies of ZIANA Gel did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects.

🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Clindamycin [See Microbiology (12.4) .] Tretinoin Although the exact mode of action of tretinoin is unknown, current evidence suggests that topical tretinoin decreases cohesiveness of follicular epithelial cells with decreased microcomedo formation. Additionally, tretinoin stimulates mitotic activity and increased turnover of follicular epithelial cells causing extrusion of the comedones.
12.3Pharmacokinetics In an open-label, multiple-dose study treating 12 subjects with moderate to severe acne, the percutaneous absorption of tretinoin following 14 consecutive daily applications of approximately 4 g of ZIANA Gel was minimal. Quantifiable tretinoin plasma concentrations ranged from 1.0 to 1.6 ng/mL, with unquantifiable plasma concentrations in 50% to 92% of subjects at any given timepoint following administration. The plasma concentrations of the key tretinoin metabolites, 13-cis-retinoic acid and 4-oxo-13-cis-retinoic acid, ranged from 1.0 to 1.4 ng/mL and from 1.6 to 6.5 ng/mL, respectively.
Plasma concentrations for clindamycin generally did not exceed 3.5 ng/mL, with the exception of one subject whose plasma concentration reached 13.1 ng/mL.
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 bacterial protein synthesis. Clindamycin has 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 activity against P. acnes was not examined in clinical trials with ZIANA Gel. P. acnes resistance to clindamycin has been documented.
Resistance to clindamycin is often associated with resistance to erythromycin.
