Home Care

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

Poison Control

Your local poison control center can be reached directly by calling the national toll-free Poison Help hotline (1-800-222-1222) from anywhere in the United States. This national hotline 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.

Note: Activated charcoal does not effectively treat (adsorb) sodium bisulfate poisoning.

For skin exposure, treatment may include:

Hospital admission may be necessary to continue treatment. Surgery may be required if the esophagus, stomach or intestine have developed holes (perforation) from exposure to the acid.

Outlook (Prognosis)

How well a person does depends on how rapidly the sodium bisulfate was diluted and neutralized. There is a good chance of recovery if proper treatment is given soon after the poison was swallowed. Without prompt treatment, extensive damage to the mouth, throat, eyes, lungs, esophagus, nose, and stomach are possible, depending on how exposure occurred.�Holes (perforations) in the esophagus and stomach may result in serious infections in both the chest and abdominal cavities, which may result in death.

Damage to the esophagus may occur as late as 2 to 3 weeks after swallowing the poison. Death may occur up to 1 month or longer after swallowing the poison. Those who recover may have continued stomach or esophagus problems, including cancer.
