Full Prescribing Info
Contents
Imiquimod.
Description
Each 0.25 gm single use sachet contains: Imiquimod 12.5 mg, Cream base q.s.
Imiquimod is an immune response modifier for topical administration. Imiquimod has a molecular formula of C14H16N4 and a molecular weight of 240.3.
Chemical Name: 1-(2-methylprophyl)-1H-imidazo[4,5-c]quinolin-4-amine.
Action
Pharmacology: Pharmacodynamics: Actinic Keratosis: In a study of 18 subjects with AK comparing Imiquimod Cream to vehicle, increases from baseline in week 2 biomarker levels were reported for CD3, CD4, CD8, CD11c, and CD68 for Imiquimod Cream treated subjects; however, the clinical relevance of these findings is unknown.
Superficial Basal Cell Carcinoma: An open label study in six subjects with sBCC suggests that treatment with Imiquimod Cream may increase the infiltration of lymphocytes, dendritic cells, and macrophages into the tumor lesion; however, the clinical significant of these findings is unknown.
External Genital Warts: Imiquimod has no direct antiviral activity in cell culture. A study in 22 subjects with genital/perianal warts comparing Imiquimod Cream and vehicle shows that Imiquimod Cream induces mRNA encoding cytokines including interferon-α at the treatment site. In addition HPVL1 mRNA and HPV DNA are significantly decreased following treatment. However, the clinical relevance of these findings is unknown.
Mechanism of Action: The mechanism of action of Imiquimod Cream in treating AK and sBCC lesions is unknown.
Pharmacokinetics: Systemic absorption of imiquimod across the affected skin of 58 subjects with AK was observed with a dosing frequency of 3 applications per week for 16 weeks. Mean peak serum drug concentrations at the end of week 16 were approximately 0.1, 0.2, and 3.5 ng/mL for the applications to face (12.5 mg imiquimod, 1 single-use packet), scalp (25 mg, 2 packets) and hands/arms (75 mg, 6 packets), respectively. (See Table 1.)

The application surface area was not controlled when more than one packet was used. Dose proportionality was not observed. However it appears that systemic exposure may be more dependent on surface area of application than amount of applied dose. The apparent half-life was approximately 10 times greater with topical dosing than the 2 hour apparent half-life seen following subcutaneous dosing, suggesting prolonged retention of drug in the skin. Mean urinary recoveries of imiquimod and metabolites combined were 0.08 and 0.15% of the applied dose in the group using 75 mg (6 packets) for males and females, respectively following 3 applications per week for 16 weeks.
Systemic absorption of imiquimod was observed across the affected skin of 12 subjects with genital/perianal wart, with an average dose of 4.6 mg. Mean peak drug concentration of approximately 0.4 ng/mL was seen during the study. Mean urinary recoveries of imiquimod and metabolites combined over the whole course of treatment, expressed as percent of the estimated applied dose, were 0.11 and 2.41% in the males and females, respectively.
Nonclinical Toxicology: Carcinogenesis, Mutagenesis and Impairment of Fertility: In an oral (gavage) rate carcinogenicity study, imiquimod was administered to Wistar rats on a 2X/week (up to 6 mg/kg/day) or daily (3 mg/kg/day) dosing schedule for 24 months. No treatment related tumors were noted in the oral rat carcinogenicity study up to the highest doses tested in this study of 6 mg/kg administered 2X/week in female rats (87X MRHD based on weekly AUC comparisons), 4 mg/kg administered 2X/week in male rates (75X MRHD based on weekly AUC comparisons) or 3 mg/kg administered 7X/week to male and female rats (153X MRHD based on weekly AUC comparisons).
In a dermal mouse carcinogenicity study, Imiquimod Cream (up to 5 mg/kg/application imiquimod or 0.3% imiquimod cream) was applied to the backs of mice 3X/week for 24 months. A statistically significant increase in the incidence of liver adenomas and carcinomas was noted in high dose male mice compared to control male mice (251X MRHD based on weekly AUC comparisons). An increased number of skin papillomas was observed in vehicle cream control group animals at the treated site only. The quantitative composition of the vehicle cream used in the dermal mouse carcinogenicity study is the same as the vehicle cream used for Imiquimod Cream, minus the active moiety (imiquimod).
In a 52-week dermal photoco-carcinogenicity study, the median time to onset of skin tumor formation was decreased in hairless mice following chronic topical dosing (3X/week; 40 weeks of treatment followed by 12 weeks of observation) with concurrent exposure to UV radiation (5 days per week) with the Imiquimod Cream vehicle alone. No additional effect on tumor development beyond the vehicle effect was noted with the addition of the active ingredient, imiquimod, to the vehicle cream.
Imiquimod revealed no evidence of mutagenic or clastogenic potential based on the results of five in vitro genotoxicity tests (Ames assay, mouse lymphoma L5178Y assay, Chinese hamster ovary cell chromosome aberration assay, human lymphocyte chromosome aberration assay and SHE cell transformation assay) and three in vivo genotoxicity tests (rate and hamster bone marrow cytogenetics assays and a mouse dominant lethal test).
Daily oral administration of imiquimod to rats, throughout mating, gestation, parturition and lactation, demonstrated no effects on growth, fertility or reproduction, at doses up to 87X MRHD based on AUC comparisons.
Indications/Uses
Actinic Keratosis: Imiquimod Cream is indicated for the topical treatment of clinically typical, nonhyperkeratotic, nonhypertrophic actinic keratoses on the face or scalp in immunocompetent adults.
Superficial Basal Cell Carcinoma: Imiquimod Cream is indicated for the topical treatment of biopsy-confirmed, primary superficial basal cell carcinoma (sBCC) in immunocompetent adults, with a maximum tumor diameter of 2.0 cm, located on the trunk (excluding anogenital skin), neck, or extremities (excluding hands and feet), only when surgical methods are medically less appropriate and patient follow-up can be reasonably assured.
The histological diagnosis of superficial basal cell carcinoma should be established prior to treatment, since safety and efficacy of Imiquimod Cream have not been established for other types of basal cell carcinomas, including nodular and morpheaform (fibrosing or sclerosing) types.
External Genital Warts: Imiquimod Cream is indicated for the treatment of external genital and perianal wart/condyloma acuminata in patients 12 years old or older.
Limitations of Use: Imiquimod Cream has been evaluated in children ages 2 to 12 years with molluscum contagiosum and these studies failed to demonstrate efficacy.
Unevaluated Populations: The safety and efficacy of Imiquimod Cream in immunosuppressed patients have not been established.
Imiquimod Cream should be used with caution in patients with pre-existing autoimmune conditions.
The efficacy and safety of Imiquimod Cream have not been established for patients with Basal Cell Nevus Syndrome or Xeroderma Pigmentosum.
Dosage/Direction for Use
The application frequency for Imiquimod Cream is different for each indication.
Imiquimod Cream is not for oral, ophthalmic, or intravaginal use.
Actinic Keratosis: Imiquimod Cream should be applied 2 times per week for a full of 16 weeks to a defined treatment area on the face or scalp (but not both concurrently). The treatment area is defined as one contiguous area of approximately 25 cm2 (e.g., 5 cm x 5 cm) on the face (e.g. forehead or one cheek) or on the scalp. Examples of 2 times per week application schedules are Monday and Thursday, or Tuesday and Friday. Imiquimod Cream should be applied to the entire treatment area and rubbed in until the cream is no longer visible. No more than one packet of Imiquimod Cream should be applied to the contiguous treatment area at each application. Imiquimod Cream should be applied prior to normal sleeping hours and left on the skin for approximately 8 hours, after which time the cream should be removed by washing the area with mild soap and water. The prescriber should demonstrate the proper application technique to maximize the benefit of Imiquimod Cream therapy.
It is recommended that patients wash their hands before and after applying Imiquimod Cream. Before applying the cream, the patient should wash the treatment area with mild soap and water and allow the area to dry thoroughly (at least 10 minutes).
Contact with the eyes, lips and nostrils should be avoided.
Local skin reactions in the treatment area are common. A rest period of several days may be taken if required by the patient's discomfort or severity of the local skin reaction. However, the treatment period should not be extended beyond 16 weeks due to missed doses or rest periods. Response to treatment cannot be adequately assessed until resolution of local reactions. Lesions that do not respond to treatment should be carefully reevaluated and management reconsidered.
Superficial Basal Cell Carcinoma: Imiquimod Cream should be applied 5 times per week for a full 6 weeks to biopsy-confirmed superficial basal cell carcinoma. An example of a 5 times per week application schedule is to apply Imiquimod Cream, once per day, Monday through Friday. Imiquimod Cream should be applied prior to normal sleeping hours and left on the skin for approximately 8 hours, after which time the cream should be removed by washing the area with mild soap and water. The prescriber should demonstrate the proper application technique to maximize the benefit of Imiquimod Cream therapy.
It is recommended that patients wash their hands before and after applying Imiquimod Cream. The patient should wash the treatment area with mild soap and water before applying the cream, and allow the area to dry thoroughly.
The target tumor should have a maximum diameter of 2 cm and be located on the trunk (excluding anogenital skin), neck, or extremities (excluding hands and feet). The treatment area should include a 1 cm margin of skin around the tumor. Sufficient cream should be applied to cover the treatment area, including 1 centimeter of skin surrounding the tumor. Imiquimod Cream should be rubbed into the treatment area until the cream is no longer visible. (See Table 2.)

Contact with the eyes, lips and nostrils should be avoided.
Local skin reactions in the treatment area are common. A rest period of several days may be taken if required by the patient's discomfort or severity of the local skin reaction.
Early clinical clearance cannot be adequately assessed until resolution of local skin reactions (e.g. 12 weeks post-treatment). Local skin reactions or other findings (e.g. infection) may require that a patient be seen sooner than the post-treatment assessment for clinical clearance. If there is clinical evidence of persistent tumor at the post-treatment assessment for clinical clearance, a biopsy or other alternative intervention should be considered. Lesions that do not respond to therapy should be carefully re-evaluated and management reconsidered; the safety and efficacy of a repeat course of Imiquimod Cream treatment have not been established. If any suspicious lesion arises in the treatment area at any time after a determination of clinical clearance, the patient should seek a medical evaluation.
External Genital Warts: Imiquimod Cream should be applied 3 times per week to external genital/perianal warts. Imiquimod Cream treatment should continue until there is total clearance of the genital/perianal warts or for a maximum of 16 weeks. Examples of 3 times per week application schedules are: Monday, Wednesday, Friday or Tuesday, Thursday, Saturday. Imiquimod Cream should be applied prior to normal sleeping hours and left on the skin for 6-10 hours, after which time the cream should be removed by washing the area with mild soap and water. The prescriber should demonstrate the proper application technique to maximize the benefit of Imiquimod Cream therapy.
It is recommended that patients wash their hands before and after applying Imiquimod Cream.
A thin layer of Imiquimod Cream should be applied to the wart area and rubbed in until the cream is no longer visible. The application site should not be occluded. Following the treatment period the cream should be removed by washing the treated area with mild soap and water.
Local skin reactions at the treatment site are common. A rest period of several days may be taken if required by the patient's discomfort or severity of the local skin reaction. Treatment may resume once the reaction subsides. Non-occlusive dressings such as cotton gauze or cotton underwear may be used in the management of skin reactions.
Overdosage
Topical overdosing of Imiquimod Cream could result in an increased incidence of severe local skin reactions and may increase the risk for systemic reactions.
The most clinically serious adverse event reported following multiple oral imiquimod doses of >200 mg (equivalent to imiquimod content of >16 packets) was hypotension, which resolved following oral or intravenous fluid administration.
Contraindications
None.
Special Precautions
Local Inflammatory Reactions: Intense local inflammatory reactions including skin weeping or erosion can occur after few applications of Imiquimod Cream and may require an interruption of dosing. Imiquimod Cream has the potential to exacerbate inflammatory conditions of the skin, including chronic graft versus host disease.
Severe local inflammatory reactions of the female external genitalia can lead to severe vulvar swelling. Severe vulvar swelling can lead to urinary retention. Dosing should be interrupted or discontinued for severe vulvar swelling.
Administration of Imiquimod Cream is not recommended until the skin is completely healed from any previous drugs or surgical treatment.
Systemic Reactions: Flu-like signs and symptoms may accompany, or even precede, local inflammatory reactions and may include malaise, fever, nausea, myalgias and rigors. An interruption of dosing should be considered.
Ultraviolet Light Exposure: Exposure to sunlight (including sunlamps) should be avoided or minimized during use of Imiquimod Cream because of concern for heightened sunburn susceptibility. Patients should be warned to use protective clothing (e.g., a hat) when using Imiquimod Cream. Patients with sunburn should be advised not to use Imiquimod Cream until fully recovered. Patients who may have considerable sun exposure, e.g. due to their occupation, and those patients with inherent sensitivity to sunlight should exercise caution when using Imiquimod Cream.
Imiquimod Cream shortened the time to skin tumor formation in an animal photocarcinogenicity study. The enhancement of ultraviolet carcinogenicity is not necessarily dependent on phototoxic mechanisms. Therefore, patients should minimize or avoid natural or artificial sunlight exposure.
Unevaluated Uses: Actinic Keratosis: Safety and efficacy have not been established for Imiquimod Cream in the treatment of actinic keratosis with repeated use, i.e. more than one treatment course, in the same area.
The safety of Imiquimod Cream applied to areas of skin greater than 252 cm (e.g. 5cm X 5cm) for the treatment of actinic keratosis has not been established.
Unevaluated Uses: Superficial Basal Cell Carcinoma: The safety and efficacy of Imiquimod Cream have not been established for other types of basal cell carcinomas (BCC), including nodular and morpheaform (fibrosing or sclerosing) types. Imiquimod Cream is not recommended for treatment of BCC subtypes other than the superficial variant (i.e., sBCC). Patients with sBCC treated with Imiquimod Cream should have regular follow-up of the treatment site.
The safety and efficacy of treating sBCC lesions on the face, head and anogenital area have not been established.
Unevaluated Uses: External Genital Warts: Imiquimod Cream has not been evaluated for the treatment of urethral, intra-vaginal, cervical, rectal, or intra-anal human papilloma viral disease.
Effects on Ability to Drive & Operate Machines: No studies on the effects on the ability to drive and use machines have been performed. From the adverse reactions noted in Adverse Reactions, it is unlikely that treatment will have any effect on the ability to drive and use machines.
Use in Children: AK and sBCC are not conditions generally seen within the pediatric population. The safety and efficacy of Imiquimod Cream for AK or sBCC in patients less than 18 years of age have not been established.
Safety and efficacy in patients with external genital/perianal warts below the age of 12 years have not been established.
Imiquimod Cream was evaluated in two randomized, vehicle-controlled, double-blind trials involving 702 pediatric subjects with molluscum contagiosum (MC) (470 exposed to Imiquimod Cream; median age 5 years, range 2-12 years). Subjects applied Imiquimod Cream or vehicle 3 times weekly for up to 16 weeks. Complete clearance (no MC lesions) was assessed at Week 18. In Study 1, the complete clearance rate was 24% (52/217) in the Imiquimod Cream group compared with 26% (28/106) in the vehicle group. In Study 2, the clearance rates were 25% (60/253) in the Imiquimod Cream group compared with 28% (35/126) in the vehicle group. These studies failed to demonstrate efficacy.
Similar to the studies conducted in adults, the most frequently reported adverse reaction from 2 studies in children with molluscum contagiosum was application site reaction. Adverse events which occurred more frequently in Imiquimod Cream-treated subjects compared with vehicle-treated subjects generally resembled those seen in studies in indications approved for adults and also included otitis media (5% Imiquimod Cream vs. 3% vehicle) and conjunctivitis (3% Imiquimod Cream vs. 2% vehicle).
Erythema was the most frequently reported local skin reaction. Severe local skin reactions reported by Imiquimod Cream-treated subjects in the pediatric studies included erythema (28%), edema (8%), scabbing/crusting (5%), flaking/scaling (5%), erosion (2%) and weeping/exudate (2%).
Systemic absorption of imiquimod across the affected skin of 22 subjects aged 2 to 12 years with extensive MC involving at least 10% of the total body surface area was observed after single and multiple doses at a dosing frequency of 3 applications per week for 4 weeks. The investigator determined the dose applied, either 1,2 or 3 packets per dose, based on the size of the treatment area and the subject's weight. The overall median peak serum drug concentrations at the end of week 4 was between 0.26 and 1.06 ng/mL except in a 2-year old female who was administered 2 packets of study drug per dose, had a Cmax of 9.66 ng/mL after multiple dosing. Children aged 25 years received doses of 12.5 mg (one packet) or 25 mg (two packets) of imiquimod and had median multiple-dose peak serum drug levels of approximately 0.2 or 0.5 ng/mL, respectively. Children aged 6-12 years received doses of 12.5 mg, 25 mg, or 37.5 mg (three packets) and had median multiple dose serum drug levels of approximately 0.1, 0.15, or 0.3 ng/mL, respectively.
Among the 20 subjects with evaluable laboratory assessments, the median WBC count decreased by 1.4*109/L and the median absolute neutrophil count decreased by 1.42*109/L.
Use in Elderly: Of the 215 subjects treated with Imiquimod Cream in the AK clinical studies, 127 subjects (59%) were 65 years and older, while 60 subjects (28%) were 75 years and older. Of the 185 subjects treated with Imiquimod Cream in the sBCC clinical studies, 65 subjects (35%) were 65 years and older, while 25 subjects (14%) were 75 years and older. No overall differences in safety or effectiveness were observed between these subjects and younger subjects. No other clinical experience has identified differences in responses between the elderly and younger subjects, but greater sensitivity of some older individuals cannot be ruled out.
Use In Pregnancy & Lactation
Pregnancy: Pregnancy Category C.
Note: The Maximum Recommended Human Dose (MRHD) was set at 2 packets per treatment of Imiquimod Cream (25 mg imiquimod) for the animal multiple of human exposure ratios presented in this label. If higher doses than 2 packets of Imiquimod Cream are used clinically, then the animal multiple of human exposure would be reduced for that dose. A non-proportional increase in systemic exposure with increase in systemic exposure with increase dose of Imiquimod was noted in the clinical pharmacokinetic study conducted in actinic keratosis subjects. The AUC after topical application of 6 packets of Imiquimod Cream was 8 fold greater than the AUC after topical application of 2 packets of Imiquimod Cream in actinic keratosis subjects. Therefore, if a dose of 6 packets per treatment of Imiquimod Cream was topically administered to an individual, then the animal multiple of human exposure would be either 1/3 of the value provided in the label (based on AUC comparisons). The animal multiples of human exposure calculations were based on weekly dose comparisons for the carcinogenicity studies described in this label. The animal multiples of human exposure calculations were based on daily dose comparisons for the reproductive toxicology studies described in this label.
Systemic embryofetal development studies were conducted in rats and rabbits. Oral doses of 1, 5 and 20 mg/kg/day imiquimod were administered during the period of organogenesis (gestational days 6-15) to pregnant female rats. In the presence of maternal toxicity, fetal effects noted at 20 mg/kg/day (577X MRHD based on comparisons) included increased resorptions, decreased fetal body weights, delays in skeletal ossification, bent limb bones, and two fetuses in one litter (2 of 1567 fetuses) demonstrated exencephaly, protruding tongues and low-set ears. No treatment related effects on embryofetal toxicity or teratogenicity were noted at 5 mg/kg/day (98X MRHD based on AUC comparisons).
Intravenous doses of 0.5, 1 and 2 mg/kg/day imiquimod were administered during the period of organogenesis (gestational days 6-18) to pregnant female rabbits. No treatment related effects on embryofetal toxicity or teratogenicity were noted at 2 mg/kg/day (1.5X MRHD based on BSA comparisons), the highest dose evaluated in this study, or 1 mg/kg/day (407X MRHD based on AUC comparisons).
A combined fertility and peri- and post-natal development study was conducted in rats. Oral doses of 1, 1.5, 3 and 6 mg/kg/day imiquimod were administered to male rats from 70 days prior to mating through the mating period and to female rats form 14 days prior to mating through parturition and lactation. No effects on growth, fertility, reproduction or post-natal development were noted at doses up to 6 mg/kg/day (87X MRHD based on AUC comparisons), the highest dose evaluated in this study. In the absence of maternal toxicity, bent limb bones were noted in the F1 fetuses at a dose of 6 mg/kg/day (87X MRHD based on AUC comparisons). This fetal effect was also noted in the oral rat embryofetal development study conducted with imiquimod. No treatment related effects on teratogenicity were noted at 3 mg/kg/day (41X MRHD based on AUC comparisons).
There are no adequate and well-controlled studies in pregnant women. Imiquimod Cream should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
Nursing Mothers: It is not known whether imiquimod is excreted in human milk following use of Imiquimod Cream. Because many drugs are excreted in human milk, caution should be exercised when Imiquimod Cream is administered to nursing women.
Adverse Reactions
Most common adverse reactions (incidence >28%) are application site reactions or local skin reactions: itching, burning, erythema, flaking/scaling/dryness, scabbing/crusting, edema, induration, excoriation, erosion, ulceration. Other reported reactions (≥1%) include fatigue, fever, and headache.
Because clinical trials are conducted under widely varying conditions, adverse reaction 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.
Clinical Trials Experience: Actinic Keratosis: The data described as follows reflect exposure to Imiquimod Cream or vehicle in 436 subjects enrolled in two double-blind, vehicle-controlled studies. Subjects applied Imiquimod Cream or vehicle to a 25 cm2 contiguous treatment area on the face or scalp 2 times per week for 16 weeks (See Tables 3 and 4.)

Local skin reactions were collected independently of the adverse reaction "application site reaction" in an effort to provide a better picture of the specific types of local reactions that might be seen. The most frequently reported local skin reactions were erythema, flaking/scaling/dryness, and scabbing/crusting. The prevalence and severity of local skin reactions that occurred during controlled studies are shown in the following table. (See Table 5.)

The adverse reactions that most frequently resulted in clinical intervention (e.g., rest periods, withdrawal from study) were local and skin application site reactions. Overall, in the clinical studies, 2% (5/215) of subjects discontinued for local skin/application site reactions. Of the 215 subjects treated, 35 subjects (16%) on Imiquimod Cream and 3 of 220 subjects (1%) on vehicle cream had at least one period. Of these Imiquimod Cream subjects, 32 (91%) resumed therapy after a rest period.
In the AK studies, 22 of 678 (3.2%) of Imiquimod-treated subjects developed treatment site infections that required a rest period off Imiquimod Cream and were treated with antibiotics (19 with oral and 3 with topical).
Of the 206 Imiquimod Cream subjects with both baseline and 8-week post-treatment scarring assessments, 6 (2.9%) had a greater degree of scarring scores at 8-weeks post-treatment than at baseline.
Clinical Trials Experience: Superficial Basal Cell Carcinoma: The data described as follows reflect exposure to Imiquimod Cream or vehicle in 364 subjects enrolled in two double-blind, vehicle-controlled studies. Subjects applied Imiquimod Cream or vehicle 5 times per week for 6 weeks. The incidence of adverse reactions reported by > 1% of subjects during the studies is summarized as follows. (See Table 6.)

The adverse reactions that most frequently resulted in clinical interventions (e.g., rest periods, withdrawal from study) were local skin and application site reactions; 10% (19/185) of subjects received rest periods. The average number of doses not received per subject due to rest periods was 7 doses with a range of 2 to 22 doses; 79% of subjects (15/19) resumed therapy after a rest period. Overall, in the clinical studies, 2% (4/185) of subjects discontinued for local skin/application site reactions.
In the sBCC studies, 17 of 1266 (1.3%) Imiquimod-treated subjects developed treatment site infections that required a rest period and treatment with antibiotics.
Clinical Trials Experience: External Genital Warts: In controlled clinical trials for genital warts, the most frequently reported adverse reactions were local skin and application site reactions.
Some subjects also reported systemic reactions. Overall, 1.2% (4/327) of the subjects discontinued due to local skin/application site reactions. The incidence and severity of local skin reactions during controlled clinical trials are shown in the following table. (See Table 9.)

Remote site skin reactions were also reported. The severe remote site skin reactions reported for females were erythema (3%), ulceration (2%), and edema (1%); and for males, erosion (2%), and erythema, edema, induration, and excoriation/flaking (each 1%). Selected adverse reactions judged to be probably or possibly related to Imiquimod Cream are listed as follows. (See Table 10.)

Click on icon to see table/diagram/image

Adverse reactions judged to be possibly or probably related to Imiquimod Cream and reported by more than 1% of subjects included: Application Site Disorders: burning, hypopigmentation, irritation, itching, pain, rash, sensitivity, soreness, stinging, tenderness.
Remote Site Reactions: bleeding, burning, itching, pain, tenderness, tinea cruris.
Body as a Whole: fatigue, fever, influenza-like symptoms.
Central and Peripheral Nervous System Disorders: headache.
Gastro-Intestinal System Disorders: diarrhea.
Musculo-Skeletal System Disorders: myalgia.
Clinical Trials Experience: Dermal Safety Studies: Provocative repeat insult patch test studies involving induction and challenge phases produced no evidence that Imiquimod Cream causes photoallergenicity or contact sensitization in healthy skin; however, cumulative irritancy testing revealed the potential for Imiquimod Cream to cause irritation, and application site reactions were reported in the clinical studies.
Post-marketing Experience: The following adverse reactions have been identified during post-approval use of Imiquimod Cream. 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. (See Table 11.)
