Symptoms
Zinc oxide poisoning can cause these symptoms:
- Fever, chills
- Cough
- Diarrhea
- Mouth and throat irritation
- Nausea and vomiting
- Stomach pain
- Yellow eyes and skin
Most of the harmful effects of zinc oxide come from breathing in the gas form of zinc oxide at industrial sites in the chemical or welding industry. This leads to a condition known as metal fume fever. Symptoms of metal fume fever include a metallic taste in the mouth, fever, headache, chest pain, and shortness of breath. Symptoms start about 4 to 12 hours after breathing in the fumes and may result in serious injury to the lungs.
Home Care
If someone swallows a lot of zinc oxide, give them water or milk right away. Do NOT give water or milk if the person is vomiting or has a decreased level of alertness.
If the chemical is on the skin or in the eyes, flush with lots of water for at least 15 minutes.
If the chemical is breathed in (inhaled), move the person to fresh air.
Call your health care provider or poison control center.
