Skin prick testing in patients using beta-blockers: a retrospective analysis.

Rationale: The use of beta-blockers is a relative contraindication in allergen skin testing yet there is a paucity of literature on adverse events in this circumstance. We examined a population of skin tested patients on beta-blockers to look for any adverse effects.

Methods: Charts from 2004-2008 in a single allergy clinic were reviewed for any patients taking a beta-blocker when skin tested.
