Pregnancy Category C: There are no adequate and well-controlled
studies in pregnant women. It is unknown whether LOVAZA can cause fetal harm
when administered to a pregnant woman or can affect reproductive capacity.
LOVAZA should be used during pregnancy only if the potential benefit to the
patient justifies the potential risk to the fetus.
Animal
DataOmega-3-acid ethyl esters have been shown to have an embryocidal
effect in pregnant rats when given in doses resulting in exposures 7 times the
recommended human dose of 4 grams/day based on a body surface area
comparison.
In female rats given oral gavage doses of 100, 600, and 2,000 mg/kg/day
beginning 2 weeks prior to mating and continuing through gestation and
lactation, no adverse effects were observed in the high dose group (5 times
human systemic exposure following an oral dose of 4 grams/day based on body
surface area comparison).
In pregnant rats given oral gavage doses of 1,000, 3,000, and 6,000 mg/kg/day
from gestation day 6 through 15, no adverse effects were observed (14 times
human systemic exposure following an oral dose of 4 grams/day based on a body
surface area comparison).
In pregnant rats given oral gavage doses of 100, 600, and 2,000 mg/kg/day
from gestation day 14 through lactation day 21, no adverse effects were seen at
2,000 mg/kg/day (5 times the human systemic exposure following an oral dose of 4
grams/day based on a body surface area comparison). However, decreased live
births (20% reduction) and decreased survival to postnatal day 4 (40% reduction)
were observed in a dose-ranging study using higher doses of 3,000 mg/kg/day (7
times the human systemic exposure following an oral dose of 4 grams/day based on
a body surface area comparison).
In pregnant rabbits given oral gavage doses of 375, 750, and 1,500 mg/kg/day
from gestation day 7 through 19, no findings were observed in the fetuses in
groups given 375 mg/kg/day (2 times human systemic exposure following an oral
dose of 4 grams/day based on a body surface area comparison). However, at higher
doses, evidence of maternal toxicity was observed (4 times human systemic
exposure following an oral dose of 4 grams/day based on a body surface area
comparison).
