According to Med-Health.net, Triamcinolone acetonide is a topical corticosteriod cream. It can be used to treat a number of skin conditions, including redness due to poison ivy. Some mild forms of the drug are available over the counter, but usually a dermatologist writes a prescription for the steroid cream.
Med-Health.net cautions that children who use Triamcinolone acetnide are more likely to develop side effects than adults; children absorb more of the substance through the skin and thus have a higher chance of overdosing. Med-Health.net warns that pregnant or breast feeding women must not use Triamcinolone acetonide, as the steroid ingredients can have negative effects on the child. Using this medication while taking other steroids or medications must be avoided, because it can result in an overdose.
