Toxicity to Animals
Special Remarks onMay cause adverse reproductive effects and birth defects (teratogenic)
Chronic Effects on Humans
Special Remarks on otherAcute Potential Health Effects:
Toxic Effects on HumansSkin: May cause skin irritation.
Eyes: May cause eye irritation.
Inhalation: Dust may cause respiratory tract irritation.
Ingestion: May be harmful if swallowed. May cause flushing, headache, somnolence, nausea and vomiting. May
also cause hypotension followed by hypertension, bradycardia, tachycardia, arteriospasm, fluid and electrolyte
imbalance, and possible seizures. It may also affect the kidneys. Blurred vision and conjunctival hemorrhage,
anxiety, difficulty breathing are rare complications.
Chronic Potential Health Effects:
Ingestion: Prolonged or repeated ingesiton may cause allergic (anaphylactoid) reaction.
Note: Uterine rupture or tears may result from high dose Oxytocin. The use of Oxytocin to induce labor may
result in intrauterine transplacental hyponatremia which may cause neonatal seizures and respiratory depression.
It may also cause neonatal hyperbilirubinemia and jaundice (effects on the liver).
