Recording adverse reactions to medication taken at work

Summary A law firm asked whether an adverse reaction to medication taken at work for a personal condition counted as a work-related injury. Under OSHA’s former recordkeeping guidance, OSHA said the on-site reaction was presumed work-related regardless of the medication’s purpose. OSHA marks this 1997 letter as archived and says it may no longer represent agency policy.

Dear Mr. Allen:

Thank you for your letter dated July 28, 1997, referencing our letter to David Coble of ELB (October 13, 1992), and requesting additional determinations for other situations regarding recordkeeping responsibilities. Please excuse the delay in our response. I will respond by restating each question and then answering it. I will cite the Recordkeeping Guidelines for Occupational Injuries and Illnesses by page and Q&A number(s) whenever possible.

1) If an employee took prescribed medication on site for allergies or any other non-work related condition rather than an injection, would an adverse reaction to the medication (i.e., rash) that surfaces at work be properly analyzed as a work related injury?

Yes. The first criterion for determining recordability is whether or not the case results from a work accident or an exposure in the work environment (Chart 2, page 32). Since the employee took the prescribed medication on site work relationship is presumed even though it was for allergies or any other non-work related condition. This case should be evaluated as an injury since the adverse reaction resulted from a single incident or something that happened in one instant; e.g., the taking of the prescribed medication (D, Distinguishing between injuries and illnesses, page 37 and D-3, page 38).

2) Does it matter if the prescription medication is being taken for a work related injury or for a non-work related condition?

No. See the above answer.

As you are aware, on February 2 [1996], OSHA published in the Federal Register a Notice of Proposed Rulemaking (NPRM) which presents its proposed revision to the injury and illness recordkeeping requirements. Included in the NPRM are proposed exemptions to our current definition of work relationship. We hope to address the issues raised in the scenarios you presented above through the revision to the recordkeeping requirements.

I hope you find this information useful. If you have any further questions, please contact us at Area Code: (202) 219-6463.

Sincerely,

Bob Whitmore
Chief
Division of Recordkeeping Requirements
