Drain opening agents can be found in many homes. Small children may drink them if given the opportunity. Common exposures include the agent splashing into the eyes when being poured as well as eye or airway burns from fumes from the "foaming" drain openers. All inhalations, eye exposures, or ingestions of these agents are extremely dangerous.

Expectations (prognosis)

The prognosis (probable outcome) depends on how rapidly the alkali was diluted. Eye exposure can be extremely dangerous and difficult to manage, and loss of vision is common. Extensive damage to the mouth, throat, and stomach are possible. The ultimate outcome depends on the extent of this damage. Damage continues to occur to the esophagus and stomach for several weeks after the alkali was swallowed. Death may occur as long as a month after the alkali was swallowed.
