Immediately call poison control center or doctor. Do not induce vomiting unless told to do so by poison control
center or doctor. Do not give any liquid to the person. Do not give anything by mouth to an unconscious
Move to fresh air. If person is not breathing, call 911 or ambulance, then give artificial respiration, preferably
mouth-to-mouth if possible.

11. TOXICOLOGICAL INFORMATION
SUBCHRONIC TOXICITY [Specific to Active Ingredient(s)]
In a 90-day subchronic feeding study in rats, the NOEL was 50 mg/kg/day. Changes in body weight and organ
weights were observed at higher dose levels. Maximum tolerated dose (MTD) was suggested to be between
250 and 1,000 mg/kg/day. No immunotoxic effects were observed in a study in mice when (S)-Hydroprene was
fed (diet) at dose levels up to and including 1,200 mg/kg/day, continuously for 30 days.
DEVELOPMENTAL/REPRODUCTIVE TOXICITY [Specific to Active Ingredient(s)]
Parental reproductive performance in rats remained unaffected up to a dose level of 7,500 ppm, when
evaluated in a 2-generation reproduction/toxicity study. Histologically, all females of 7,500 ppm dose group
had cytoplasmic vacuolation in the ovaries and regression of corpora lutea, but without affecting reproductive
performance. The NOEL for pup development was 1,500 ppm. No teratogenic or fetotoxic effects were
observed in rats when pregnant animals were exposed (gavage) to (S)-Hydroprene at levels up to 1,000
mg/kg/day (highest dose tested) during days 6 to 15 of gestation. NOEL for maternal toxicity was 1,000
mg/kg/day. Minor skeletal anomalies observed at lower dose levels were absent in the high dose animals,
indicating an observation unrelated to the dose treatment.
MUTAGENICITY [Specific to Active Ingredient(s)]
(S)-Hydroprene is not a mutagen.
