From the Guidelines

Kennalog cream is not the most effective treatment for poison ivy rash, as studies have shown that over-the-counter corticosteroids, including 0.2% hydrocortisone lotion, 1.0% hydrocortisone ointment, 2.5% hydrocortisone ointment, and 2.5% hydrocortisone cream, do not improve symptoms 1. Instead, the most effective treatment for poison ivy rash involves washing the affected area with soap and water as soon as possible after exposure, which can remove up to 100% of poison ivy oils if done immediately 1. For symptomatic relief, cool compresses and oatmeal baths are frequently recommended, although they are supported by little evidence 1. If symptoms persist or worsen, oral steroids prescribed by a doctor may be more appropriate, especially for severe or widespread poison ivy rashes involving the face or genitals. It's essential to discontinue use and seek medical attention if the rash worsens or shows signs of infection like increased pain, swelling, warmth, or pus. Some key points to consider when treating poison ivy rash include:

  • Washing the affected area with soap and water as soon as possible after exposure
  • Avoiding over-the-counter corticosteroids that have not been shown to improve symptoms
  • Considering cool compresses and oatmeal baths for symptomatic relief
  • Seeking medical attention if symptoms persist or worsen.

From the FDA Drug Label

INDICATIONS AND USAGE Triamcinolone acetonide cream, 0.1% is indicated for the relief of the inflammatory and pruritic manifestations of corticosteroid-responsive dermatoses.

  • Kennalog cream, which is another name for triamcinolone acetonide cream, can be used for the treatment of poison ivy if it is a corticosteroid-responsive dermatosis.
  • The cream is used for relief of inflammatory and pruritic manifestations.
  • Poison ivy is a type of dermatosis that can cause inflammation and pruritus, so triamcinolone acetonide cream may be used to treat it 2.

From the Research

Kennalog Cream for Poison Ivy

  • Kennalog cream is a type of topical corticosteroid, however, the study 3 does not specifically mention the use of Kennalog cream for poison ivy.
  • The study 3 focuses on the treatment patterns and utilization of systemic corticosteroids for poison ivy dermatitis, and found that shorter duration oral corticosteroids are associated with an increased risk for return visits to healthcare clinicians.
  • The study 3 recommends treating poison ivy dermatitis with oral steroids for at least 14 days, but does not provide information on the use of topical corticosteroids like Kennalog cream.
  • There is no direct evidence in the study 3 to support the use of Kennalog cream for poison ivy, and its effectiveness for this condition is not evaluated.
