Clostridium difficile-Associated Diarrhea (CDAD)
Clostridium difficile-associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents, including clindamycin, and may range in severity from mild diarrhea to fatal colitis. Treatment with antibacterial agents alters the normal flora of the colon leading to overgrowth of C. difficile.
C. difficile produces toxins A and B which contribute to the development of CDAD. Hypertoxin producing strains of C. difficile cause increased morbidity and mortality, as these infections can be refractory to antimicrobial therapy and may require colectomy. CDAD must be considered in all patients who present with diarrhea following antibiotic use. Careful medical history is necessary since CDAD has been reported to occur over two months after the administration of antibacterial agents.
If CDAD is suspected or confirmed, ongoing antibiotic use not directed against C. difficile may need to be discontinued. Appropriate fluid and electrolyte management, protein supplementation, antibiotic treatment of C. difficile, and surgical evaluation should be instituted as clinically indicated [see ADVERSE REACTIONS].
Use with Condoms and Vaginal Contraceptive Diaphragms
This cream contains mineral oil that may weaken latex or rubber products such as condoms or vaginal contraceptive diaphragms. Therefore, the use of such barrier contraceptives is not recommended concurrently or for 5 days following treatment with Clindesse (clindamycin phosphate) . During this time period, condoms may not be reliable for preventing pregnancy or for protecting against transmission of HIV and other sexually transmitted diseases.
Patient Counseling Information
Vaginal Intercourse and Use with Vaginal Products
Instruct the patient not to engage in vaginal intercourse, or use other vaginal products (such as tampons or douches) during treatment with this product.
Use with Condoms and Vaginal Contraceptive Diaphragms
Advise the patient that this cream contains mineral oil that may weaken latex or rubber products such as condoms or vaginal contraceptive diaphragms. Therefore, do not use barrier contraceptives concurrently or for 5 days following treatment with Clindesse (clindamycin phosphate) . During this time period, condoms may not be reliable for preventing pregnancy or for protecting against transmission of HIV and other sexually transmitted diseases [see WARNINGS AND PRECAUTIONS].
Fungal Vaginal Infections
Accidental Exposure to the Eye
Inform the patient that Clindesse (clindamycin phosphate) contains ingredients which cause burning and irritation of the eye. In the event of accidental contact with the eye, rinse the eye with copious amounts of cool tap water and consult a physician.
Carcinogenesis, Mutagenesis, Impairment of Fertility
Long-term studies in animals have not been performed with clindamycin to evaluate carcinogenic potential. Genotoxicity tests performed included a rat micronucleus test and an Ames test. Both tests were negative. Fertility studies in rats treated orally with up to 300 mg/kg/day (29 times the recommended human dose based on body surface area comparisons) revealed no effects on fertility or mating ability.
Use In Specific Populations
Pregnancy Category B
Clindesse (clindamycin phosphate) should be used during pregnancy only if clearly needed. There are no adequate and well-controlled studies of Clindesse (clindamycin phosphate) in pregnant women.
Another intravaginal formulation containing 2% clindamycin phosphate has been studied in pregnant women during the second trimester. In women treated for seven days, abnormal labor was reported in 1.1% of patients who received that clindamycin vaginal cream formulation compared with 0.5% of patients who received placebo.
Reproduction studies have been performed in rats and mice using oral and parenteral doses of clindamycin up to 600 mg/kg/day (58 and 29 times, respectively, the recommended human dose based on body surface area comparisons) and have revealed no evidence of harm to the fetus due to clindamycin.
Because animal reproduction studies are not always predictive of human response, Clindesse (clindamycin phosphate) should be used during pregnancy only if clearly needed.
Caution should be exercised when Clindesse (clindamycin phosphate) is administered to a nursing woman. It is not known if clindamycin is excreted in human milk following the use of vaginally administered clindamycin. Clindamycin has been detected in human milk after oral or parenteral administration.
Because of the potential for serious adverse reactions in nursing infants, a decision to continue or discontinue nursing should take into account the importance of the drug to the mother.
The safety and efficacy of Clindesse (clindamycin phosphate) in the treatment of bacterial vaginosis in post-menarchal females have been established on the extrapolation of clinical trial data from adult women. The safety and efficacy of Clindesse (clindamycin phosphate) in pre-menarchal females have not been established.
Clinical studies with Clindesse (clindamycin phosphate) did not include sufficient numbers of subjects 65 years of age or older to determine whether they respond differently than younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients.This monograph has been modified to include the generic and brand name in many instances.
