약물의 분류: 각성제 임신부 약물등급(US FDA): C
임신부 안전 및 기형발생정보 :Caffeine intake in humans does not appear to increase the risk of congenital anomalies. There are conflicting data on whether caffeine is associated with an increased risk of miscarriage or a decrease in birth weight. The studies suggesting these adverse effects identify 200-300 mg/day (equivalent to about 2-3 cups of coffee or 4-6 cans of cola) as the dose above which toxicity might occur.
모유수유부 약물등급(Medication and Mother’s MilK): L2
모유수유 안전 및 유해성정보 :Caffeine is excreted in human milk but milk caffeine concentrations are only about 1% of maternal plasma concentrations. The half-life of caffeine in the milk was 4 hours. Because newbornbiotransformation of caffeine is limited, even small regular doses of caffeine might produce clinically significant plasma concentrations. Although the American Academy of Pediatrics classified caffeine among drugs that are usually compatible with breastfeeding, the possibility of infant irritability or sleep disturbances was noted. A prospective cohort study examined 885 infants born to mothers with documented caffeine intake during pregnancy and the first 3 months of breastfeeding. Nearly 20% were considered to be heavy consumers (at least 300 mg/day) during pregnancy and 14.3% were heavy consumers 3 months postpartum. No association was seen with nighttime awakening in the infants at 3 months of age. The accidental exposure of a premature infant to a high dose of caffeine (300 mg/kg) was associated with irritability, tachycardia, tachypnea, diuresis, electrolyte abnormalities, hyperglycemia, and metabolic acidosis, but these symptoms resolved over a period of 96 hours with only supportive treatment. No long-term effect was noted.
