From the Guidelines
For a 16-year-old with poison ivy, the most effective treatment is to wash the affected area with soap and lukewarm water as soon as possible to remove any remaining plant oils, as this can remove up to 100% of poison ivy oils if done immediately after contact 1.
Initial Treatment
- Wash the affected area with soap and lukewarm water to remove any remaining plant oils
- This should be done as soon as possible, as the effectiveness of washing decreases over time, with a 50% reduction in effectiveness at 10 minutes, 25% at 15 minutes, and 10% at 30 minutes 1
Symptomatic Relief
- Apply cool compresses to the affected area to help relieve itching and inflammation, as suggested by the 2024 American Heart Association and American Red Cross guidelines for first aid 2
- Oatmeal baths may also be considered for relief of local symptoms from exposure to poison ivy, oak, or sumac, although the evidence for this is limited 2
- Topical corticosteroids, such as hydrocortisone cream, may be used to reduce itching and inflammation, but their effectiveness is uncertain and they may not be available over the counter 1, 3
Additional Measures
- Avoid scratching the affected area to prevent infection and secondary skin damage
- Over-the-counter antihistamines, such as diphenhydramine or cetirizine, may be used to help control itching, but their effectiveness is uncertain and they may not provide significant relief 2, 3
- If the rash is severe, covers a large portion of the body, affects the face or genitals, shows signs of infection, or doesn't improve within a week, seek medical attention as prescription-strength steroids or antibiotics may be necessary 1, 2, 3

From the Research
Treatment Overview
The treatment for contact dermatitis caused by Toxicodendron radicans (poison ivy) in a 16-year-old adolescent depends on the severity of the reaction.
- The nurse practitioner can manage the majority of poison ivy cases, but if there is systemic involvement, a physician consultation is necessary 5.
- Treatment approaches include washing the area immediately with a solvent suitable for lipids and the use of anti-inflammatory agents, especially corticosteroids 6.
Supportive Therapy
Supportive therapy can be prescribed to assist the patient, and teaching preventive measures is also important 5.
- Prophylactic measures include avoidance, protective clothing, barrier creams, and hyposensitization 6.
- Clinicians should educate their patients on how to identify and avoid contact with poison ivy and related plants 7.
Current Therapies
Although extensive efforts have been made to develop therapies that prevent and treat contact dermatitis to these plants, there lacks an entirely effective method, besides complete avoidance 8.
