Stibine gas is an industrial byproduct that contains antimony. Stibine poisoning is uncommon, but it usually occurs due to inhalation exposure.

The toxic mechanism of stibine is not clear but likely involves inhibition of enzymes that protect the body from oxidative stress.

Acute stibine poisoning is a cause of hemorrhagic gastroenteritis, arrhythmia, and hemolysis. Chronic exposure (often in the workplace) can cause pneumonitis, dermatitis, and headache.

Treatment is supportive, utilizing intravenous (IV) fluids, electrolyte supplementation, and blood transfusion. Stibine poisoning is not typically lethal if supportive care is provided.
