Who Can Administer Prophylaxis? Authorized Healthcare Professionals by Role and State

Administration of prophylactic medications (e.g., post-exposure prophylaxis for HIV, rabies, anthrax; pre-exposure PrEP; antimicrobial surgical prophylaxis) is governed by state scope-of-practice laws, institutional policy, and medication-specific protocols.

Commonly Authorized Professionals

Professional	Typical Authority	Notes
Physicians (MD/DO)	Full independent	Prescribe and administer
Physician Assistants (PA)	Delegated, supervised	Per delegation agreement
Nurse Practitioners (NP)	Independent or collaborative	Varies by state (full/reduced/restricted practice)
Registered Nurses (RN)	Physician order/protocol	Cannot independently prescribe; administer per order
Licensed Practical/Vocational Nurses (LPN/LVN)	RN/physician direction	Scope narrower than RN; IV push may be restricted
Pharmacists	Protocol/CDTM	Many states allow PEP/PrEP dispensing/administration per protocol
Paramedics/EMTs	Medical director protocol	Emergency PEP (e.g., occupational exposure)
Medical Assistants (MA)	Direct supervision	Injections only if state law + delegation permit; no independent assessment
Chiropractors (DC)	Very limited	Few states allow any injection therapy; not for systemic prophylaxis

Critical Requirements

• Current BLS/ACLS as required.
• Competency validation for specific route (IM, IV, SubQ, ID).
• Medication-specific training (e.g., HIV PEP protocol, rabies PEP schedule).
• Documentation: order, administration, lot/expiry, site, patient education, adverse event monitoring.

Always verify current state statutes, board rules, and facility policies. Scope of practice evolves legislatively.
