The following drug information is obtained from various newswires, published
medical journal articles, and medical conference presentations.
Company: EnviroDerm Pharmaceuticals
Approval Status: Approved September 1996
Treatment Area: skin protectant for poison ivy, poison oak, and poison sumac
IvyBlock has been approved as a poison ivy, poison oak, and
poison sumac skin protectant. Ivy Block should be applied to skin
at least 15 minutes before possible contact with the poisonous
plants and re-applied every four hours for continued protection.
The lotion may be removed with soap and water.
Mechanism of Action
According to EnviroDerm, Ivy Block lays down an active barrier
on the skin with a special formula that helps block skin contact
with urushiol, the oil in the plants which triggers the rash,
thereby serving to help protect against poison ivy, poison oak, and
poison sumac rash.
Clinical data can be found in the August 1995 issue of the
Journal of the American Academy of Dermatology.
Poison ivy can affect two out of three Americans, and of these,
15% may have severe allergic reactions, which require medical
treatment. In 1994, more than nine million Americans sought
remedies for the irritation caused by poison ivy, oak, and sumac.
According to the National Safety Council, these poisonous plants
are the largest cause of occupational contact dermatitis for
outdoor workers in many areas of the country.
