Strattera - Patient Info

(Page 3)

These findings were observed at doses that caused slight maternal toxicity. The no-effect dose for these findings was 30 mg/ kg/ day. The 100-mg/ kg dose is approximately 23 times the maximum human dose on a mg/ m 2 basis; plasma levels (AUC) of atomoxetine at this dose in rabbits are estimated to be 3.3 times (extensive metabolizers) or 0.4 times (poor metabolizers) those in humans receiving the maximum human dose.

Rats were treated with up to approximately 50 mg/ kg/ day of atomoxetine (approximately 6 times the maximum human dose on a mg/ m 2 basis) in the diet from 2 weeks (females) or 10 weeks (males) prior to mating through the periods of organogenesis and lactation. In 1 of 2 studies, decreases in pup weight and pup survival were observed. The decreased pup survival was also seen at 25 mg/ kg (but not at 13 mg/ kg). In a study in which rats were treated with atomoxetine in the diet from 2 weeks (females) or 10 weeks (males) prior to mating throughout the period of organogenesis, a decrease in fetal weight (female only) and an increase in the incidence of incomplete ossification of the vertebral arch in fetuses were observed at 40 mg/ kg/ day (approximately 5 times the maximum human dose on a mg/ m 2 basis) but not at 20 mg/ kg/ day.

No adverse fetal effects were seen when pregnant rats were treated with up to 150 mg/ kg/ day (approximately 17 times the maximum human dose on a mg/ m 2 basis) by gavage throughout the period of organogenesis. No adequate and well-controlled studies have been conducted in pregnant women.

STRATTERA should not be used during pregnancy unless the potential benefit justifies the potential risk to the fetus.

Labor and Delivery

Parturition in rats was not affected by atomoxetine. The effect of STRATTERA on labor and delivery in humans is unknown.

Nursing Mothers

Atomoxetine and/ or its metabolites were excreted in the milk of rats. It is not known if atomoxetine is excreted in human milk. Caution should be exercised if STRATTERA is administered to a nursing woman.
