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 (clindamycin phosphate) in 368 patients. Clindesse (clindamycin phosphate)
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 (clindamycin phosphate) , 1.6% of the patients
discontinued therapy due to adverse reactions. Adverse reactions occurred in
126 of 368 patients (34%) treated with Clindesse (clindamycin phosphate) and in 32 of 85 patients (38%)
treated with placebo.
Adverse reactions occurring in ≥ 1% of patients receiving Clindesse (clindamycin phosphate) in the
three clinical studies are shown in Table 1.
