Disaster Medicine 101: What to Do When Help Isn’t Coming

By: Dr. JR Dadivas, Founder of Prepped Health

When the Lights Go Out, You’re the First Responder

Most people think about food, water, and flashlights when disaster strikes. But what about your medications?

Natural disasters, civil unrest, power grid failures, and pandemics don’t just knock out infrastructure — they cut off access to pharmacies, clinics, and hospitals when you need them most.

Disaster medicine isn’t about panic. It’s about preparedness. And in a true emergency, your ability to stay calm, think clearly, and treat the people around you may depend on what you packed ahead of time.

Common Scenarios Where Disaster Medicine Applies

• Hurricanes, tornadoes, earthquakes, and wildfires

• Prolonged power outages (days to weeks)

• Flooded roads and collapsed infrastructure

• Civil unrest or lockdowns

• Mass casualty events

• Pandemic-related system overloads

These events strain or entirely eliminate access to:

• Emergency rooms

• Pharmacies

• First responders

• Clean water and power

What Happens to Medication Access During Disasters?

• Pharmacies close or run out of stock

• Supply chains are disrupted

• Medications that need refrigeration (like insulin) may spoil

• Refill requests may be delayed or denied

• Controlled substances become inaccessible

Core Categories of Meds to Have On Hand

1. Daily Maintenance Meds:

   • Blood pressure, diabetes, asthma, thyroid, mental health

   • Aim to keep at least a 30–90 day backup supply

2. Acute Illness Meds:

   • Antibiotics (e.g., Amoxicillin, Azithromycin)

   • Antivirals if appropriate (e.g., Valacyclovir)

   • Antifungals or anti-parasitics for specific risks

3. Emergency Meds:

   • Naloxone (Narcan)

   • EpiPen (for anaphylaxis)

   • Inhalers (albuterol)

   • Pain relievers (NSAIDs + acetaminophen)

4. GI + Dehydration Meds:

   • Loperamide

   • Ondansetron

   • Oral Rehydration Salts

5. Wound Care + Infection Prevention:

   • Topical antibiotic ointment (mupirocin)

   • Antiseptics (povidone-iodine, alcohol pads)

   • Hemostatic gauze

   • Sterile dressings and closure strips

6. Allergy + Inflammation:

   • Antihistamines (diphenhydramine, loratadine)

   • Oral steroids (if prescribed)

Med Storage Tips During Grid Failure

• Store meds in a cool, dry place (preferably airtight containers)

• Use portable coolers or medical-grade cold packs for insulin or biologics

• Rotate your emergency stock annually (watch expiration dates)

• Keep paper copies of prescriptions and allergy lists

• Use moisture absorbers and backup lighting in your med storage zone

The Urban Survival Kit: More Than First Aid

A true disaster-ready kit includes:

• Medications (Rx and OTC)

• Wound care and trauma supplies

• Gloves, CPR mask, Narcan

• Water purification tabs or filter

• Flashlight/headlamp

• Emergency blanket

• Fire starter

• Multitool

• N95 or KN95 masks

Bonus: Keep a PLB (personal locator beacon) like the ACR ResQLink or Garmin inReach Mini in your go-bag in case of total communication failure.

Final Takeaway: In a Disaster, Readiness Is Medicine

You won’t rise to the occasion — you’ll fall to your level of preparation.

Disaster medicine isn’t just about surviving the impact — it’s about making it through the aftermath. When emergency systems break down, you become the frontline.
