Home Treatment

Seek immediate medical help. DO NOT make a person throw up unless told to do so by Poison Control or a health care professional.

If the chemical is on the skin or in the eyes, flush with lots of water for at least 15 minutes.

If the chemical was swallowed, immediately give the person water or milk, unless instructed otherwise by a health care provider. DO NOT give water or milk if the patient is having symptoms (such as vomiting, convulsions, or a decreased level of alertness) that make it hard to swallow.

If the person breathed in the poison, immediately move him or her to fresh air.

Before Calling Emergency

If possible, determine the following information:

• Patient's age, weight, and condition (for example, is the person awake or alert?)
• Name of the product (ingredients and strengths, if known)
• When it was swallowed or inhaled
• How much was swallowed or inhaled

However, DO NOT delay calling for help if this information is not immediately available.
