Side Effects (Adverse Reactions)
6 ADVERSE REACTIONS The most frequently reported (≥1%) adverse reactions were erythema,scaling, dryness, and/or burning/stinging. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Encube Ethicals Private Limited at 1-833-285-4151 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reactions rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. In the multi-center, controlled clinical trial, signs and symptoms of local cutaneous irritation were monitored in 258 acne subjects who used Adapalene gel, 0.3% once daily for 12 weeks. Of the subjects who experienced cutaneous irritation (erythema, scaling, dryness, and/or burning/stinging), the majority of cases were mild to moderate in severity, occurred early in treatment and decreased thereafter. The incidence of local cutaneous irritation with Adapalene gel, 0.3% from the controlled clinical trial is provided in the following table: Table 1: Physician assessed local cutaneous irritation with Adapalene gel Incidence of Local Cutaneous Irritation with Adapalene gel, 0.3% (N = 253*) Maximum Severity Scores Higher Than Mild Moderate Severe Erythema 66 (26.1%) 33 (13.0%) 1 (0.4%) Scaling 110 (43.5%) 47 (18.6%) 3 (1.2%) Dryness 113 (44.7%) 43 (17.0%) 2 (0.8%) Burning / Stinging 72 (28.5%) 36 (14.2%) 9 (3.6%) * Total number of subjects with local cutaneous data for at least one post-Baseline evaluation. Table 2: Patient reported local cutaneous adverse reactions with Adapalene Gel Adapalene Gel, 0.3% Vehicle Gel N = 258 N = 134 Related* Adverse Reactions Dry Skin Skin Discomfort 57 (22.1%) 36 (14%) 15 (5.8%) 4 (1.6%) 6 (4.5%) 2 (1.5%) 0 (0.0%) 0 (0.0%) * Selected adverse reactions defined by investigator as Possibly, Probably or Definitely Related The following adverse reactions occurred in less than 1 % of subjects: acne flare, contact dermatitis, eyelid edema, conjunctivitis, erythema, pruritus, skin discoloration, rash, and eczema. In a one-year, open-label safety trial of 551 subjects with acne who received Adapalene gel, 0.3%, the pattern of adverse reactions was similar to the 12-week controlled study. 6.2 Postmarketing Experience The following adverse reactions have been identified during post approval use of adapalene: Immune system disorders: angioedema, face edema, lip swelling Skin disorders: application site pain Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate the frequency or establish a causal relationship to drug exposure.
Contraindications
4 CONTRAINDICATIONS Adapalene gel, 0.3% is contraindicated in patients who have known hypersensitivity to adapalene or any excipient of adapalene gel, 0.3% [see WARNINGS AND PRECAUTIONS (5.1) ].

Pregnancy and Breastfeeding
8.1 Pregnancy Risk Summary Available data from clinical trials with Adapalene Gel, use in pregnant women are insufficient to establish a drug-associated risk of major birth defects, miscarriage or other adverse maternal or fetal outcomes. In animal reproduction studies, oral administration of adapalene to pregnant rats and rabbits_ during organogenesis at dose exposures 40 and 81 times, respectively, the human exposure at the maximum recommended human dose (MRHD) of 2 g resulted in fetal skeletal and visceral malformations ( see Data ) . The background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defects, loss, or other adverse outcomes. In the U.S. general population the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies are 2 to 4% and 15 to 20%, respectively. Data Animal Data No malformations were observed in rats treated with oral adapalene doses of 0.15 to 5.0 mg/kg/day, up to 8 times the MRHD based on a mg/m 2 comparison. However, malformations were observed in rats and rabbits when treated with oral doses of ≥ 25 mg/kg/day adapalene (40 and 81 times the MRHD, respectively, based on a mg/m 2 comparison). Findings included cleft palate, microphthalmia, encephalocele, and skeletal abnormalities in rats and umbilical hernia, exophthalmos, and kidney and skeletal abnormalities in rabbits. Dermal adapalene embryofetal development studies in rats and rabbits at doses up to 6.0 mg/kg/day (9.7 and 19.5 times the MRHD, respectively, based on a mg/m 2 comparison) exhibited no fetotoxicity and only minimal increases in skeletal variations (supernumerary ribs in both species and delayed ossification in rabbits).
Overdosage
10 OVERDOSAGE Chronic ingestion of the drug may lead to the same side effects as those associated with excessive oral intake of vitamin A.
