Medical Preparedness for Disasters: The Filipino Family Guide to Medicine, First Aid, and Post-Flood Illness

When people prepare for typhoons and earthquakes, the shopping list usually looks the same: water, canned goods, flashlight, batteries, radio. What almost never makes the list is medicine — and that is the gap that hurts families the most once the water goes down and the roads stay closed.

In disaster response work, the pattern repeats itself. In the first 24 hours, the emergencies are physical: trauma, drowning, collapsed structures. But from day three onward, the queue at any medical station is filled with something different — people with diabetes who ran out of insulin, people with hypertension who left their maintenance meds at home, wounds that were never cleaned properly, and children with fever and diarrhea. These are not dramatic emergencies. They are preventable ones.

This guide covers medical preparedness for Filipino families: what to stock, how to protect your maintenance medicines, what PhilHealth and DOH provide during declared emergencies, and the two illnesses that follow flooding almost every single year.

Why medicine is the most overlooked part of a go bag

Food and water have a comfortable margin. Most families can stretch what is in the kitchen for two or three days without much planning. Medicine has no margin at all. If you take one tablet a day and you have three tablets left, you have three days — no substitutions, no rationing that is actually safe.

Three things make this worse during a disaster:

• Pharmacies close or run out. After a major typhoon, the nearest open botika may be several barangays away, and the supply chain that restocks it is on the same flooded road you are.
• Prescriptions become unreachable. If your records are only at one clinic and that clinic is closed or damaged, refilling a controlled medicine gets complicated fast.
• Evacuation happens in a hurry. Families grab children, documents, and phones. The blister pack on the kitchen shelf is the thing everyone assumes someone else picked up.

The fix is not expensive. It is mostly a matter of deciding in advance where the medicine lives and how much of it you keep ahead.

The 7-day rule for maintenance medicines

If anyone in your household takes daily maintenance medication — for hypertension, diabetes, heart conditions, asthma, epilepsy, thyroid, mental health, or any chronic condition — the target is simple: always hold at least seven days of supply beyond what you are currently using.

How to build that buffer without doubling your budget in one month:

1. Ask your doctor at your next check-up whether an early or slightly larger refill is appropriate for emergency preparedness. Many will agree; some medicines have restrictions, so this is a conversation, not a decision to make alone.
2. Build the buffer gradually. Buy a few extra tablets each refill cycle rather than a full extra month at once.
3. Rotate, do not stockpile. Use the oldest supply first and replace it with the newest. Medicine that expires in the cabinet has helped nobody.
4. Store the buffer where you will actually take it — inside or beside the go bag, not in the bedroom drawer.

The same rotation discipline you use for canned goods works here. If you have not set that habit yet, the method in Never Let Your Typhoon Supplies Expire Again transfers directly to medicine.

What belongs in a household medical kit

Separate your kit into two layers. The first layer handles injuries. The second layer handles the illnesses that show up days later.

Layer 1 — Wound and injury care

• Sterile gauze pads and roller gauze
• Adhesive bandages in several sizes
• Adhesive tape
• Antiseptic solution (povidone-iodine is the common choice in Philippine households)
• Clean water set aside specifically for wound irrigation
• Disposable gloves — at least a few pairs
• Scissors and tweezers
• Elastic bandage for sprains and pressure

Layer 2 — Illness and comfort

• Oral rehydration salts (ORS) — the single most valuable item on this list
• Paracetamol, in both adult and pediatric forms if you have children
• Any personal maintenance medicines, with a written list of names and dosages
• Thermometer
• Alcohol or hand sanitizer
• Insect repellent
• Extra eyeglasses, and contact lens supplies if applicable

A note on ORS: after a flood, dehydration from diarrhea is one of the most common reasons families end up needing medical help, and it is one of the easiest to manage early. ORS sachets are inexpensive, last for years, and take almost no space. Ten sachets in a go bag is a reasonable starting point for a family.

One item that belongs beside the kit rather than inside it is a working light source. Cleaning and dressing a wound properly at night without a flashlight is far harder than people expect, and a phone screen held in your teeth is not a solution.

The paper that matters: your medical information sheet

Write this on one page, put it in a resealable plastic bag, and place a copy in every go bag. Also photograph it and keep the photo on your phone.

• Full name, birthdate, and blood type of each family member
• Chronic conditions for each person
• Complete list of current medicines, with dosage and frequency
• Known allergies — especially drug allergies
• PhilHealth number (PIN) for each member
• Name and contact number of your usual doctor or health center
• Emergency contact who lives outside your area

The reason this page matters is not bureaucratic. If a family member is treated by someone who has never met them, that sheet is the difference between careful treatment and guesswork. It is especially critical for drug allergies and for anyone on medication that cannot be stopped abruptly.

Keep this page with your other documents. If your family communication plan is not settled yet, pair this with the approach in Emergency Radio and Communication When Cell Networks Are Down — the medical sheet and the contact plan should live in the same pouch.

PhilHealth and DOH: what to know before you need it

During declared calamities, government health services usually adjust to reduce barriers to care. What changes, and how, is announced case by case — so treat the following as things to verify rather than assume:

• Know your PhilHealth PIN and keep it written down. Membership records can usually be confirmed even without a physical card, but knowing your number makes admission far smoother.
• Know where your nearest Barangay Health Station and Rural Health Unit are, and know a second option in a different direction — the nearest facility may be the one that flooded.
• Follow DOH and your LGU health office announcements during an emergency. Medical missions, free medicine distribution, and temporary treatment areas are announced through these channels, and locations change daily in the first week.
• Do not delay care while waiting for paperwork. Coverage questions can be sorted out afterward; a worsening infection cannot.

Benefit rules and special calamity provisions change over time. Check the current official announcements rather than relying on what applied during the last typhoon.

Leptospirosis and dengue: the two that follow the flood

These two deserve their own section because they arrive predictably, and because both are far more manageable when caught early.

Leptospirosis

Transmitted through contact with water contaminated by animal urine — which describes most floodwater in an urban area. It enters through cuts, scratches, or prolonged skin exposure, and symptoms typically appear days to weeks after wading.

What actually reduces risk:

• Avoid wading whenever there is any alternative. This is the only measure that works reliably.
• If you must enter floodwater, cover open wounds first and wear boots if you have them.
• Wash with clean water and soap immediately afterward, and clean any cuts properly.
• If you develop fever, severe muscle pain (especially in the calves), headache, or reddened eyes after flood exposure, seek medical attention and say clearly that you waded in floodwater. That detail changes how you are assessed.

Preventive antibiotic treatment after high-risk exposure is sometimes provided through health centers, but it is a medical decision — ask, do not self-medicate.

Dengue

Mosquito populations rise in the weeks after flooding because standing water multiplies breeding sites. The prevention is unglamorous and effective: eliminate standing water around your home — tires, buckets, plant saucers, roof gutters, discarded containers, and anything else holding water for more than a few days.

Warning signs that need immediate medical attention include persistent vomiting, severe abdominal pain, bleeding from gums or nose, and a sudden drop in fever accompanied by the person becoming weak or restless. Do not wait these out at home.

For both illnesses, the practical principle is the same: fever after a flood is not something to observe for several days. Get it checked.

Keeping the family healthy in an evacuation center

Crowded shared spaces change the risk profile. Respiratory infections and gastrointestinal illness spread quickly, and children and elderly family members are affected first.

• Handwashing before eating and after using the toilet — this single habit prevents more illness in evacuation centers than anything else available.
• Drink only water you are confident about. If in doubt, boil it or use treated water. Keep the food handling basics from How to Store Emergency Water and Food Safely in mind — they matter more, not less, when you are away from home.
• Wear footwear at all times, including at night. Cuts on the feet in a wet, crowded environment are the classic route to infection.
• Keep your medicine kit with you, not in a shared pile.
• Speak up early about a family member’s condition. Health workers on site can plan around a known chronic illness; they cannot plan around one they learn about during a crisis.

Decision points

When something happens, use these to decide quickly:

1. Fever after flood exposure → seek care, and mention the flood exposure. Do not wait to see if it passes.
2. Down to three days of maintenance medicine → start arranging a refill now, not when the last tablet is gone.
3. Wound exposed to floodwater → clean it with clean water and soap immediately, and have it evaluated if it is deep, dirty, or shows redness and swelling within a day.
4. Diarrhea in a child → start ORS early. The point of ORS is to prevent dehydration, not to treat it once it is severe.
5. Anything you are unsure about in a person with a chronic condition → get it checked sooner than you would for a healthy adult.

What to do today

Pick the first item and do it now. The rest can follow this week.

• Count the remaining days of every maintenance medicine in your household. Write the number down.
• Write the one-page medical information sheet and put it in a plastic bag.
• Add ten ORS sachets to your kit.
• Check the expiry date on everything already in your first aid kit and throw out what has lapsed.
• Save your PhilHealth PIN and your nearest health center’s number in your phone — and on paper.
• Walk around your house once and empty anything holding standing water.

If you have children, one more thing worth doing this week: check that their individual bags include a small share of the medical supplies. The priorities in Go Bag ng Bata apply here — light, but genuinely useful.

Summary

Medical preparedness is not about buying a large kit. It is about three decisions made in advance: hold seven days of maintenance medicine, write the medical information sheet, and stock ORS. Those three cover the majority of what actually goes wrong in Filipino households after a typhoon or earthquake.

The illnesses that follow a disaster are rarely dramatic. They are fever, dehydration, infected wounds, and interrupted treatment for conditions people were already managing well. All four respond to preparation that costs very little and takes an afternoon to set up.

The families who come through a disaster in the best shape are usually not the ones with the biggest supply of goods. They are the ones who decided, before anything happened, where the medicine is kept and who carries it.
