Further Outpatient Care


With most cases involving outpatient treatment, complete resolution of symptoms should occur within 3 weeks of therapy.

Complications include infection and hyperpigmentation of the involved area.

Weekly follow-up visits are recommended to document the progress of treatment.


Further Inpatient Care

Water hemlock

See the list below:

  • Symptoms of cicutoxin should manifest within 2 hours of observation in the ED.
  • In a symptomatic patient, close monitoring of respiratory status is essential.
  • Care is mostly supportive with particular attention to fluid balance (because of GI loss); benzodiazepines are used for possible seizures.


Currently, pharmaceutical companies and the United States military actively research protective agents to prevent contact dermatitis from resin skin exposure.

Currently, Hylands produces an over-the-counter barrier product called Ivyblock, which is reported to prevent dermatitis preexposure. The active ingredient is bentoquatam (5%). It must be applied before possible exposure and reapplied at least every 4 hours. It may give the user a false sense of security since it may wash or be wiped off easily. It should be applied 15 minutes before risk of exposure. In adults and children aged 6 years and older, apply every 4 hours for continued protection or sooner if needed.

Oral or injectable forms of the resin have been studied in the past in order to desensitize the individual. Results were inconsistent at best. Currently, diluted forms of the resin for oral ingestion can be found in the food supplement section of pharmacies. This is not approved by the US Food and Drug Administration. Past reports have documented individuals chewing on the leaves in order to desensitize the individual, which clearly has potentially dangerous consequences.
