If the person swallowed a lot of zinc oxide, immediately give the person water or milk. DO NOT give water or milk if the patient 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 doctor or poison control.
Before Calling Emergency
Determine the following information:
- Patient's age, weight, and condition
- Name of the product (as well as the ingredients and strength, if known)
- Time it was swallowed
- Amount swallowed
Poison Control
The National Poison Control Center (1-800-222-1222) can be called from anywhere in the United States. This national hotline number will let you talk to experts in poisoning. They will give you further instructions.
This is a free and confidential service. All local poison control centers in the United States use this national number. You should call if you have any questions about poisoning or poison prevention. It does NOT need to be an emergency. You can call for any reason, 24 hours a day, 7 days a week.
Take the container with you to the hospital, if possible.

What to Expect at the Emergency Room
The health care provider will measure and monitor the patient's vital signs, including temperature, pulse, breathing rate, and blood pressure. Symptoms will be treated as appropriate.
Outlook (Prognosis)
Zinc oxide is not very toxic (poisonous) when you mistakenly eat it. Most of the harmful effects come from breathing in the gas form of zinc oxide at industrial sites in the chemical industry. This leads to a condition known as "metal fume fever."
Either way, long-term recovery is very likely.
