ACUTE EXPOSURE INFORMATION
- WITH POISONING/EXPOSURE
- ACUTE INHALATION: Acute aspiration of talc causes cough, dyspnea, tachypnea, sneezing, vomiting, cyanosis, and pulmonary edema which may be delayed up to several hours. Cardiorespiratory arrest may occur following severe aspiration.
- CHRONIC INHALATION of industrial talc dusts or body talc produces talcosis due to talc, silica, and asbestos (talc pneumoconiosis) characterized by productive cough, dyspnea, rales, diminished breath sounds, limited chest expansion, interstitial fibrosis, and granulomas.
- INTRAVENOUS INJECTION of talc-containing tablets or capsules produces foreign body vascular granulomatas (microemboli) at the site of intramuscular or subcutaneous injection and widespread arterial wall granulomas. Angiothrombotic pulmonary arterial hypertension and cor pulmonale may develop. Pulmonary effects include nonproductive cough, fever, dyspnea, and granulomatosis. Subtle x-ray changes may develop showing symmetrical hilar and perihilar interstitial infiltrations which are only minimally reversible.
