PRECAUTIONS

Colitis

Systemic absorption of clindamycin has been demonstrated following topical use of this product. Diarrhea, bloody diarrhea, and colitis (including pseudomembranous colitis) have been reported with the use of topical clindamycin. If significant diarrhea occurs, EVOCLIN Foam should be discontinued. [See ADVERSE REACTIONS.]

Severe colitis has occurred following oral or parenteral administration of clindamycin with an onset of up to several weeks following cessation of therapy. Antiperistaltic agents such as opiates and diphenoxylate with atropine may prolong and/or worsen severe colitis. Severe colitis may result in death.

Studies indicate a toxin(s) produced by Clostridia is one primary cause of antibiotic-associated colitis. The colitis is usually characterized by severe persistent diarrhea and severe abdominal cramps and may be associated with the passage of blood and mucus. Stool cultures for Clostridium difficile and stool assay for C. difficile toxin may be helpful diagnostically.

Irritation

EVOCLIN Foam can cause irritation. Concomitant topical acne therapy should be used with caution since a possible cumulative irritancy effect may occur, especially with the use of peeling, desquamating, or abrasive agents. If irritation or dermatitis occurs, clindamycin should be discontinued.

Avoid contact of EVOCLIN Foam with eyes, mouth, lips, other mucous membranes or areas of broken skin. If contact occurs, rinse thoroughly with water.

EVOCLIN Foam should be prescribed with caution in atopic individuals.

Patient Counseling Information

See FDA-Approved patient labeling (PATIENT INFORMATION).

Instructions for Use

  • Patients should be advised to wash their skin with mild soap and allow it to dry before applying EVOCLIN Foam.
  • Patients should use enough EVOCLIN Foam to cover the face and to apply once daily.
  • Patients should dispense EVOCLIN Foam directly into the cap or onto a cool surface.
  • Patients should wash their hands after applying EVOCLIN Foam.

Skin Irritation

EVOCLIN Foam may cause irritation such as erythema, scaling, itching, burning, or stinging. Patients should be advised to discontinue use if excessive irritancy or dermatitis occur.

Colitis

In the event a patient treated with EVOCLIN Foam experiences severe diarrhea or gastrointestinal discomfort, EVOCLIN Foam should be discontinued and a physician should be contacted.

Nonclinical Toxicology

Carcinogenesis, Mutagenesis, Impairment of Fertility

The carcinogenicity of a 1.2% clindamycin phosphate gel similar to EVOCLIN Foam was evaluated by daily application to mice for two years. The daily doses used in this study were approximately 3 and 15 times higher than the human dose of clindamycin phosphate from 5 milliliters of EVOCLIN Foam, assuming complete absorption and based on a body surface area comparison. No significant increase in tumors was noted in the treated animals.

A 1.2% clindamycin phosphate gel similar to EVOCLIN Foam caused a statistically significant shortening of the median time to tumor onset in a study in hairless mice in which tumors were induced by exposure to simulated sunlight.

Genotoxicity tests performed included a rat micronucleus test and an Ames Salmonella reversion test. Both tests were negative.

Reproduction studies in rats using oral doses of clindamycin hydrochloride and clindamycin palmitate hydrochloride have revealed no evidence of impaired fertility.

Use In Specific Populations

Pregnancy

Pregnancy Category B: There are no adequate and well-controlled studies in pregnant women treated with EVOCLIN Foam. EVOCLIN Foam should be used during pregnancy only if the potential benefit clearly outweighs the potential risk to the fetus.

Reproduction studies have been performed in rats and mice using subcutaneous and oral doses of clindamycin phosphate, clindamycin hydrochloride and clindamycin palmitate hydrochloride. These studies revealed no evidence of fetal harm. The highest dose used in the rat and mouse teratogenicity studies was equivalent to a clindamycin phosphate dose of 432 mg/kg. For a rat, this dose is 84 fold higher, and for a mouse 42 fold higher, than the anticipated human dose of clindamycin phosphate from EVOCLIN Foam based on a mg/m² comparison.

Nursing Mothers

It is not known whether clindamycin is excreted in human milk following use of EVOCLIN Foam. However, orally and parenterally administered clindamycin has been reported to appear in breast milk. Because of the potential for serious adverse reactions in nursing infants, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.

If used during lactation and EVOCLIN Foam is applied to the chest, care should be taken to avoid accidental ingestion by the infant.

Pediatric Use

Safety and effectiveness of EVOCLIN Foam in children under the age of 12 have not been studied.

Geriatric Use

The clinical study with EVOCLIN Foam did not include sufficient numbers of subjects aged 65 and over to determine if they respond differently than younger subjects.
