Pregnancy & Breastfeeding
8.1 Pregnancy Pregnancy Category C. There are no well-controlled trials in pregnant women treated with Clindamycin Phosphate 1.2% and Tretinoin 0.025% Gel. Clindamycin Phosphate 1.2% and Tretinoin 0.025% Gel should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Clindamycin Phosphate 1.2% and Tretinoin 0.025% Gel was tested for maternal and developmental toxicity in New Zealand White Rabbits with topical doses of 60, 180 and 600 mg/kg/day. Clindamycin Phosphate 1.2% and Tretinoin 0.025% Gel at 600 mg/kg/day (approximately 12 times the recommended clinical dose assuming 100% absorption and based on body surface area comparison) was considered to be the no-observed-adverse-effect level (NOAEL) for maternal and developmental toxicity following dermal administration of Clindamycin Phosphate 1.2% and Tretinoin 0.025% Gel for 2 weeks prior to artificial insemination and continuing until gestation day 18, inclusive. For purposes of comparisons of the animal exposure to human exposure, the recommended clinical dose is defined as 1 g of Clindamycin Phosphate 1.2% and Tretinoin 0.025% Gel applied daily to a 60 kg person. Clindamycin Teratology (Segment II) studies using clindamycin were performed orally in rats (up to 600 mg/kg/day) and mice (up to 100 mg/kg/day) (583 and 49 times amount of clindamycin in the recommended clinical dose based on body surface area comparison, respectively) or with subcutaneous doses of clindamycin up to 180 mg/kg/day (175 and 88 times the amount of clindamycin in the recommended clinical dose based on body surface area comparison, respectively) revealed no evidence of teratogenicity. Tretinoin In oral Segment III studies in rats with tretinoin, decreased survival of neonates and growth retardation were observed at doses in excess of 2 mg/kg/day (~78 times the recommended clinical dose assuming 100% absorption and based on body surface area comparison).
