The Ultimate Pre-Trip Health Checklist (Physician-Approved)

From our experience treating returned travelers, roughly 22% to 64% of international travelers experience some form of illness during or after their trip, and the majority of these cases are preventable with basic pre-travel preparation. This checklist covers everything you need to handle before departure: vaccinations, prescription medications, travel insurance, a well-stocked health kit, and destination-specific precautions. The ideal window to start is 4 to 6 weeks before your flight, though even last-minute travelers can cover the essentials. Below is the exact process we recommend to every patient heading abroad.

Why You Need a Pre-Trip Health Checklist

Most travelers spend weeks researching restaurants and booking excursions but spend zero minutes thinking about their health. We see the consequences of that gap regularly. A 2023 study published in the Journal of Travel Medicine found that only 36% of US travelers to developing countries sought pre-travel health advice, despite the CDC recommending a consultation for nearly all international trips.

The reality is that travel health preparation is not complicated. It just requires starting early enough. Vaccines take time to build immunity (some need multiple doses over weeks). Prescription medications like antimalarials need to be started before you leave. And if you wait until the week before your trip, your options narrow considerably.

This checklist is organized by timeline so you can work through it whether you have six weeks or six days.

The 4-to-6-Week-Out Checklist

Starting a full month or more before departure gives you the widest range of options for vaccines, medications, and insurance. This is the ideal window.

1. Research Your Destination's Health Requirements

Every country has a different health risk profile. Before you do anything else, look up your destination on the CDC Travelers' Health page to find out:

• Which vaccines are recommended or required
• Whether malaria prophylaxis (antimalarial medication) is needed
• Current disease outbreaks or health advisories
• Food and water safety precautions

Some countries require proof of vaccination for entry. Yellow fever vaccination, for example, is mandatory for travelers entering parts of sub-Saharan Africa and South America. Without the certificate, you may be denied boarding or turned away at immigration.

Wandr's destination health hub provides country-specific guides with all the vaccine, medication, and health precautions you need in one place, saving you from piecing together information across multiple government websites.

2. Schedule Vaccinations

Vaccines are the single most effective thing you can do to protect yourself abroad. The specific vaccines you need depend on where you're going, how long you're staying, and what activities you have planned.

Routine vaccines to confirm are up to date:

• Measles, mumps, rubella (MMR)
• Tetanus, diphtheria, pertussis (Tdap), boosted every 10 years
• Influenza (seasonal flu)
• COVID-19 (current formulation)
• Polio (if traveling to endemic areas)

Travel-specific vaccines to discuss with a provider:

• Hepatitis A (recommended for most developing countries, 2-dose series)
• Hepatitis B (recommended for longer trips or potential medical exposure)
• Typhoid (recommended for South Asia, Africa, parts of Latin America)
• Yellow fever (required for parts of Africa and South America)
• Japanese encephalitis (recommended for rural areas of Southeast Asia)
• Rabies (recommended for adventure travelers, rural stays, or countries with limited medical access)
• Meningococcal (required for Hajj pilgrimage, recommended for sub-Saharan Africa's "meningitis belt")

The timing matters. Hepatitis A needs at least 2 weeks before departure for the first dose to take effect. Yellow fever requires vaccination at least 10 days before arrival in a mandatory-vaccination country. Rabies pre-exposure prophylaxis requires a 3-dose series over 21 to 28 days. Starting early gives you room to complete multi-dose series and build full immunity.

You can book vaccine appointments through Wandr to skip the hassle of calling multiple pharmacies to check availability and pricing. Most travelers save $100 or more compared to traditional travel clinic consultations, which typically charge a $75 to $150 office visit fee on top of vaccine costs.

3. Get Prescription Travel Medications

Depending on your destination, you may need prescription medications that your regular doctor might not think to prescribe. According to a 2024 analysis in Travel Medicine and Infectious Disease, fewer than half of primary care physicians feel confident advising patients on travel-specific prescriptions.

Common travel prescriptions to discuss:

• Antimalarials (atovaquone-proguanil/Malarone): Required for travel to malaria-endemic regions. Malarone is started 1 to 2 days before arrival. See our complete malaria prevention guide for a detailed comparison.
• Traveler's diarrhea antibiotics (ciprofloxacin or azithromycin): A standby prescription you carry in case of moderate to severe symptoms. Traveler's diarrhea affects 30% to 70% of travelers to high-risk destinations according to the CDC. Our traveler's diarrhea guide covers when and how to use these.
• Altitude sickness medication (acetazolamide/Diamox): Recommended if you're trekking above 2,500 meters (8,200 feet) or ascending rapidly. Start 24 hours before reaching altitude. See our altitude sickness guide.
• Motion sickness medication (meclizine): Available over-the-counter or by prescription. Ideal for cruises, boat excursions, and winding mountain roads.
• Anti-nausea medication: For travelers prone to nausea from motion, altitude changes, or unfamiliar foods.

With Wandr, you can get all these prescriptions online and have them shipped directly to your door, no travel clinic appointment needed. Most orders arrive within 3 to 5 business days, and you'll save hundreds compared to a traditional travel clinic visit.

4. Review Your Health Insurance and Get Travel Insurance

This is the step most travelers skip, and it's the one that can cost you the most. Your domestic health insurance likely does not cover medical care abroad. Medicare provides zero international coverage. Most private plans cover only emergency care and may require you to pay upfront and file for reimbursement later.

Travel medical insurance typically costs $30 to $150 for a two-week trip and can cover:

• Emergency medical treatment and hospitalization
• Medical evacuation (which can cost $50,000 to $200,000+ without insurance)
• Trip cancellation and interruption
• Emergency dental care
• Repatriation of remains

According to the US Travel Insurance Association, the average medical evacuation from a developing country costs $100,000 or more. A helicopter evacuation from a remote trekking region can exceed $250,000. For the cost of a decent dinner out, travel insurance eliminates that financial risk entirely.

In our clinical experience, the travelers who need evacuation are rarely the ones who expected to. A broken ankle on a cobblestone street, an allergic reaction in a rural area, acute appendicitis in a country with limited surgical facilities: these are everyday scenarios our providers have seen treated.

The 2-to-4-Week-Out Checklist

With a few weeks to go, shift your focus to assembling supplies and handling logistics.

5. Build Your Travel Health Kit

A well-packed health kit covers the gaps between prevention and treatment. You don't need to bring a pharmacy, but you do need the basics for the most common travel health issues.

Essential items for every international trip:

• Prescription medications (in original labeled containers, with copies of prescriptions)
• Oral rehydration salts (ORS packets) for dehydration from diarrhea or heat
• Loperamide (Imodium) for mild diarrhea symptom management
• Antibiotic prescription (ciprofloxacin or azithromycin, if prescribed)
• Pain relievers: ibuprofen (Advil)
• Antihistamine (cetirizine/Zyrtec) for allergic reactions
• 1% hydrocortisone cream for insect bites and skin irritation
• Adhesive bandages, gauze, medical tape
• Thermometer (digital, compact)
• Sunscreen (SPF 30 or higher, broad-spectrum)
• Insect repellent containing 20% to 30% DEET or 20% picaridin (CDC-recommended concentrations)
• Hand sanitizer (at least 60% alcohol)
• Water purification tablets or a filtered water bottle (for destinations with unsafe tap water)

For specific destinations, add:

• Permethrin-treated clothing or bed net (malaria-endemic regions)
• Altitude medication if trekking (see your prescription list)
• EpiPen (if you have known severe allergies)
• Motion sickness medication (cruises, winding roads)
• Electrolyte packets beyond ORS (for hot climates or high-altitude trekking)

Keep all prescription medications in their original pharmacy-labeled bottles. Some countries require proof that your medications were legally prescribed, and having the label simplifies any questions at customs.

6. Handle Medication Logistics

If you take daily medications (blood pressure, birth control, antidepressants, insulin, or others), plan ahead:

• Carry enough supply for the entire trip plus 7 extra days in case of delays
• Keep medications in carry-on luggage, never checked bags
• Bring a letter from your prescribing physician listing your medications, dosages, and medical conditions (especially for controlled substances)
• Check your destination's drug import laws (some common medications are controlled or banned in certain countries)
• Set phone reminders for any medications that need to be taken at specific times, and adjust for time zone changes

If you use injectable medications (insulin, biologics), carry a physician's letter and keep supplies in a temperature-controlled case. Most airlines allow medical supplies through security with documentation.

7. Copy and Store Important Documents

Create digital and physical copies of:

• Passport (photo page)
• Travel insurance policy and emergency contact number
• Vaccination records (International Certificate of Vaccination, the "yellow card," if applicable)
• Prescription copies and physician letters
• Emergency contact information (both at home and at your destination)
• Embassy or consulate contact information for your destination country

Store digital copies in a secure cloud service and email them to yourself. Keep physical copies separate from the originals. If your passport is lost or stolen, having copies dramatically speeds up the replacement process at your country's embassy.

The 1-Week-Out Checklist

You're almost there. This final week is about confirming everything is in place.

8. Confirm Vaccination Records and Prescription Supply

Verify that:

• All vaccines are complete and documented (allow enough time for immunity to develop)
• Prescription medications have arrived and are correctly labeled
• Antimalarials are on hand with clear start dates noted (Malarone: start 1 to 2 days before arrival)
• Your travel health kit is packed and accessible
• Travel insurance documents are accessible digitally and in print

9. Check for Last-Minute Health Advisories

Health conditions change. A disease outbreak, a natural disaster, or a new travel advisory can appear at any time. In the week before departure:

• Check the CDC Travelers' Health Notices for your destination
• Check the US State Department travel advisories
• Review the WHO Disease Outbreak News for any new alerts
• If a new advisory appears for your destination, contact your travel health provider to discuss whether additional precautions are needed

10. Prepare for Jet Lag and In-Flight Health

Long-haul flights come with their own health considerations:

• Hydration: Cabin air humidity drops to 10% to 20% (compared to a comfortable 30% to 65% at home). Drink water consistently throughout the flight and limit alcohol and caffeine, both of which are dehydrating.
• Deep vein thrombosis (DVT) prevention: Flights over 4 hours increase DVT risk. Stand and walk the aisle every 1 to 2 hours. Flex your ankles and calves while seated. Compression socks reduce risk further. The CDC notes that the risk of DVT roughly doubles for flights over 4 hours.
• Jet lag management: Adjust your sleep schedule 1 to 2 hours toward your destination time zone in the days before departure. Melatonin (0.5 to 3 mg) taken at bedtime in your destination's time zone works well for resetting your circadian rhythm, according to a Cochrane Review analysis.
• Carry-on essentials: Keep all medications, a change of clothes, and critical documents in your personal bag, not your checked luggage.

Day-of-Departure Final Check

Before you walk out the door, run through this quick confirmation:

• Prescription medications packed in carry-on (original containers)
• Travel health kit accessible
• Vaccination records (physical and digital copies)
• Travel insurance card or policy number easily reachable
• Antimalarial medication started (if applicable per your dosing schedule)
• Destination emergency numbers saved in your phone
• Embassy contact information saved
• Insurance company's international emergency hotline saved

What If You Only Have a Few Days Before Your Trip?

Not everyone has six weeks. If you're leaving soon, here's what to prioritize:

1. Get prescriptions filled immediately. Online platforms like Wandr can ship medications within 3 to 5 business days. For same-day needs, some medications are available at most local pharmacies with a prescription.
2. Get expedited vaccines. Hepatitis A provides some protection even with just one dose given days before departure. Yellow fever is effective after 10 days but may still be administered closer to departure in urgent situations.
3. Buy travel insurance now. Most policies can be purchased up to the day before departure. Some even cover pre-existing conditions if purchased within 14 to 21 days of your initial trip deposit.
4. Pack a basic health kit. Even if you can't get prescription antibiotics in time, ORS packets, loperamide, pain relievers, insect repellent, and sunscreen are available at any pharmacy without a prescription.

The key principle: something is always better than nothing. Even partial preparation dramatically reduces your risk.

Common Mistakes We See in Returned Travelers

From our clinical experience, these are the patterns we see repeatedly:

• Skipping antimalarials because "it's only a short trip." Malaria doesn't care about your itinerary length. A single infected mosquito bite is enough. The CDC recommends prophylaxis for all travel to malaria-endemic areas regardless of trip duration.
• Packing medications in checked luggage. Lost luggage means lost medications. Always keep prescriptions in your carry-on.
• Assuming your domestic insurance works abroad. We've seen travelers receive $80,000+ hospital bills in countries where their insurance had zero coverage.
• Drinking tap water or using ice without checking local safety. Traveler's diarrhea is the most common travel illness worldwide, affecting up to 70% of travelers to high-risk regions. Bottled or purified water only.
• Waiting until the last minute. The most common thing we hear from sick travelers is "I meant to get prepared, but I ran out of time." Starting four to six weeks early solves this entirely.

Frequently Asked Questions

How far in advance should I start preparing for international travel health?

Ideally, start 4 to 6 weeks before departure. This gives enough time for multi-dose vaccine series, prescription medication shipping, and insurance research. Some vaccines like rabies require 3 doses over 21 to 28 days, so starting early keeps all options open.

Do I need to see a doctor before traveling internationally?

The CDC recommends a pre-travel health consultation for most international trips, especially to developing countries. You don't necessarily need an in-person visit. Online travel health platforms like Wandr provide physician consultations and prescriptions remotely, often at a lower cost than traditional travel clinics.

What vaccines do I need for international travel?

It depends on your destination. Common travel vaccines include hepatitis A, typhoid, yellow fever, and Japanese encephalitis. You should also confirm your routine vaccines (MMR, Tdap, flu, COVID-19) are current. Check the CDC's destination pages or Wandr's travel health guides for country-specific recommendations.

How much does pre-trip health preparation cost?

Costs vary by destination and needs. Vaccines range from $50 to $350 each. Prescription medications (antimalarials, antibiotics) range from $20 to $200 depending on the drug and duration. Travel insurance averages $30 to $150 for a two-week trip. Traditional travel clinics add $75 to $150 in consultation fees. Online platforms like Wandr eliminate the consultation fee and often offer lower medication pricing.

Can I get travel medications without visiting a travel clinic?

Yes. Online travel health platforms like Wandr allow you to complete a health questionnaire reviewed by a licensed physician, receive prescriptions digitally, and have medications shipped to your home. This typically saves both time and money compared to in-person travel clinics.

What should I pack in a travel health kit?

At minimum: prescription medications, ORS packets, loperamide, pain relievers, antihistamines, adhesive bandages, sunscreen (SPF 30+), insect repellent with 20% to 30% DEET, hand sanitizer, and a digital thermometer. Add destination-specific items like bed nets or altitude medication as needed.

Is travel insurance really necessary?

Medical evacuation alone can cost $50,000 to $250,000+ without insurance. Most domestic health plans provide zero or minimal international coverage, and Medicare covers nothing abroad. For $30 to $150, travel medical insurance eliminates catastrophic financial risk. From our clinical experience, the travelers who need it most are rarely the ones who expected to.

What if I'm leaving in less than a week?

Prioritize prescriptions (some can be filled same-day at local pharmacies), get at least a first dose of hepatitis A vaccine, purchase travel insurance (available up to the day before departure), and assemble a basic health kit from your local pharmacy. Partial preparation is always better than none.
