SIDE EFFECTS

Clinical Study 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 to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

The data described below reflect exposure to Clindesse in 368 patients. Clindesse was studied in three clinical studies: placebo-controlled (n=85), active-controlled (n=263), and single-arm (n=20). The population was female, aged 18 to 78, who were diagnosed with bacterial vaginosis. Patient demographics in the trials were 51% Caucasian, 36% Black, 10% Hispanic, and 3% Asian, other or unknown. All patients received 100 mg clindamycin phosphate cream intravaginally in a single dose.

Of the 368 women treated with a single dose of Clindesse, 1.6% of the patients discontinued therapy due to adverse reactions. Adverse reactions occurred in 126 of 368 patients (34%) treated with Clindesse and in 32 of 85 patients (38%) treated with placebo.

Adverse reactions occurring in ≥2% of patients receiving Clindesse in the placebo-controlled clinical trial are shown in Table 1.

The use of clindamycin may result in the overgrowth of non-susceptible fungal organisms in the vagina and may require antifungal treatment

Other reactions reported by <1% of those women treated with Clindesse include:

Dermatologic: Pruritic rash

Gastrointestinal: Diarrhea, vomiting

General: Fatigue

Immune System: Hypersensiitivity

Nervous System: Dizziness

Reproductive System: Dysfunctional uterine bleeding, dysmennorrhea, intermenstrual bleeding, pelvic pain, vaginal burning, vaginal irritation, vulvar erythema, vulvitis, vulvovaginal discomfort, vulvovaginal dryness, vulvovaginitis

Other Clindamycin Formulations

Clindesse affords minimal peak serum levels and systemic exposure (AUCs) of clindamycin compared to an oral or intravenous dose of clindamycin [see CLINICAL PHARMACOLOGY]. Data from well-controlled trials directly comparing clindamycin administered orally to clindamycin administered vaginally are not available.

The following additional adverse reactions and altered laboratory tests have been reported with the oral or parenteral use of clindamycin:

Gastrointestinal: Abdominal pain, esophagitis, nausea, Clostridium difficile-associated diarrhea [see WARNINGS AND PRECAUTIONS].

Hematopoietic: Transient neutropenia (leukopenia), eosinophilia, agranulocytosis, and thrombocytopenia have been reported. No direct etiologic relationship to concurrent clindamycin therapy could be made in any of these reports.

Hypersensitivity Reactions: Maculopapular rash, vesiculobullous rash, and urticaria have been observed during drug therapy. Generalized mild to moderate morbilliform-like skin rashes are the most frequently reported of all adverse reactions. Cases of erythema multiforme, some resembling Stevens-Johnson syndrome, have been associated with clindamycin. A few cases of anaphylactoid reactions have been reported.

Liver: Jaundice and abnormalities in liver function tests have been observed during clindamycin therapy.

Musculoskeletal: Cases of polyarthritis have been reported.

Renal: Although no direct relationship of clindamycin to renal damage has been established, renal dysfunction as evidenced by azotemia, oliguria, and/or proteinuria has been observed in rare instances.

Postmarketing Experience

The following adverse reactions have been identified during postapproval use of Clindesse. 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.

Dermatologic: Rash

Gastrointestinal: Hematochezia

Reproductive System: Vaginal erythema, vulvovaginal pruritis, vaginal discharge, vaginal swelling, vaginal bleeding, vaginal pain

DRUG INTERACTIONS

No formal drug interaction studies have been conducted for Clindesse.

Neuromuscular Blocking Agents

Orally or intravenously administered clindamycin has neuromuscular blocking properties that may enhance the action of other neuromuscular blocking agents. Therefore, it should be used with caution in patients receiving such agents.
