In this episode of CoROM Conversations, Aebhric O'Kelly is joined by Dr Bill Vasios to discuss one of the most overlooked aspects of remote and austere medicine: the intelligent use of over-the-counter (OTC) medications in austere primary care.
Rather than focusing on advanced equipment and prescription drugs, this discussion explores how a carefully selected collection of inexpensive, widely available medications can effectively manage many of the illnesses and injuries encountered in remote, expeditionary, humanitarian and disaster settings.
The conversation emphasises clinical reasoning, careful assessment, conservative prescribing, and making the most of simple interventions before escalating treatment.

Key Take-Home Messages
Good assessment should always precede medication.
Oral hydration remains the cornerstone of treating dehydration.
Many common conditions can be managed safely with inexpensive OTC medications.
Every item carried should ideally have multiple uses.
Patient education and involvement improve outcomes.
Simple treatments, applied correctly, are often more effective than complicated ones.
