Memorial Day is around the corner, and for many of our members, that means flights are booked, passports are ready, and itineraries are set. But there is one part of trip planning that often gets left until the last minute: preparing your body for what you are about to put it through. Different food, different water, different time zones, different illnesses. The destination research takes hours. The medical preparation usually takes zero.

At Griffin Concierge Medical, travel preparation is one of the most practical benefits of membership. Here is what that looks like: we build you a personalized Griffin Travel Pack tailored to your destination and health profile, administer many travel vaccines right in our office, and make sure you have the prescriptions you need before you leave. While you are away, your Griffin physician is accessible via telemedicine, and an on-call physician is a text or phone call away for any urgent issues, regardless of your time zone. If you need care abroad, we coordinate through our network of national and international healthcare professionals. And through our partnership with MedJet, Griffin members receive a 20% discount on medical transport membership for emergency evacuation coverage.

All we ask is about two weeks of lead time to prepare your travel pack and coordinate any vaccines. This article covers what goes into that preparation and why it matters more than most travelers realize.

Pre-Trip Medical Preparation: The 4-6 Week Window

The ideal time to start travel medical planning is four to six weeks before departure. Some vaccines require multiple doses over several weeks, and certain prophylactic medications need to be started before you arrive at your destination. That said, even a one-week runway is better than nothing - many preparations can be accelerated.

Here's what a comprehensive pre-trip consultation at Griffin Concierge Medical covers:

Destination Risk Assessment

Every destination has a specific risk profile. A business trip to London requires different preparation than a safari in Tanzania or a backpacking trip through Southeast Asia. We evaluate risks based on the CDC's destination-specific guidelines and WHO travel advisories, including endemic diseases, food and water safety, altitude, insect-borne illness risk, and access to medical facilities.

Vaccine Review and Administration

Travel vaccines fall into three categories: routine (vaccines every adult should have regardless of travel), recommended (based on destination-specific risks), and required (mandated for entry to certain countries).

Vaccine	When It's Indicated	Timing Notes
Hepatitis A	Most international destinations, especially developing countries	Single dose provides protection within 2-4 weeks; booster at 6-12 months for long-term immunity
Hepatitis B	All international travelers (if not already vaccinated)	3-dose series over 6 months; accelerated schedule available
Typhoid	South Asia, Africa, parts of Central/South America	Oral (4 doses over 1 week) or injectable (single dose, 2 weeks before travel)
Yellow Fever	Sub-Saharan Africa, tropical South America	Required for entry to many countries; single dose, at least 10 days before travel
Japanese Encephalitis	Rural Asia, extended stays	2-dose series, completed at least 1 week before travel
Rabies (Pre-Exposure)	High-risk destinations with limited medical access; animal contact expected	3-dose series over 4 weeks; simplifies post-exposure treatment if bitten
Meningococcal	Sub-Saharan "meningitis belt," Hajj pilgrimage	Single dose; required for Saudi Arabia entry during Hajj/Umrah

We also verify that routine immunizations - Tdap, MMR, influenza, COVID-19, and varicella - are current. Many adults are under-vaccinated for diseases they were immunized against as children, and booster status matters when traveling to areas with active transmission. We can administer most travel vaccines right in our office, so you do not need to find a separate travel clinic or pharmacy.

Let us know where you are traveling as early as possible so we can determine which vaccinations are recommended and order them if needed. Some vaccines require multiple doses or need time to take effect before departure.

Travel Prescriptions

Before you leave, we take care of two things. First, we make sure you have enough of your regular prescriptions to cover the full length of your trip, including a buffer in case of delays. Running out of a daily medication in a foreign country is a problem we never want our members to face. Second, we prescribe destination-specific medications you may need if you get sick while traveling. U.S.-licensed physicians cannot prescribe internationally, so if something comes up abroad, the medications in your travel pack are your first line of defense.

Common travel prescriptions include antibiotics for traveler's diarrhea (azithromycin or ciprofloxacin depending on your destination), anti-nausea medication (ondansetron), a broad-spectrum antibiotic for respiratory or skin infections, and altitude medication for high-elevation destinations. Your physician will tailor the list based on where you are going and your health profile, and every prescription comes in original pharmacy-labeled containers with clear instructions.

The Jet Lag Protocol: A Physiological Approach

Jet lag isn't just feeling tired. It's a circadian rhythm disruption with measurable effects on cognition, digestion, immune function, and hormone regulation. Your body's internal clock is anchored by light exposure, melatonin secretion, cortisol timing, and core body temperature - and when you cross multiple time zones, all of these signals are suddenly misaligned with the local environment.

Most people try to manage jet lag by willpower: stay awake until local bedtime, drink coffee, push through. This works poorly. A physiological approach works significantly better:

Eastward Travel (Hardest Direction)

Eastward travel requires advancing your circadian clock - going to sleep earlier and waking earlier than your body expects. This is harder than delaying it.

• Pre-trip: Shift your sleep schedule 30-60 minutes earlier per day for 3-4 days before departure
• On arrival: Seek bright morning light (outdoor sunlight is best) as early as possible. This is the single most powerful circadian signal.
• Melatonin: Take 0.5-3mg of melatonin at your target bedtime at the destination, starting the first night. Low doses (0.5-1mg) are often as effective as higher doses with fewer side effects.
• Avoid: Bright light in the evening at your destination for the first 2-3 days. Wear blue-light-blocking glasses after sunset if needed.
• Caffeine: Use strategically in the morning only. Avoid after noon local time.

Westward Travel (Easier Direction)

Westward travel requires delaying your clock - staying awake later and sleeping later. Most people adapt faster to westward travel.

• Pre-trip: Shift sleep schedule 30-60 minutes later per day for 2-3 days before departure
• On arrival: Seek bright light in the late afternoon and evening. Stay active and awake until a reasonable local bedtime.
• Avoid: Early morning bright light for the first few days (it will advance your clock in the wrong direction). Wear sunglasses if you're up early.
• Napping: Short naps (20-30 minutes) are acceptable if needed, but avoid sleeping more than 30 minutes or napping after 3 p.m. local time.

For members who use wearable devices like Oura Ring or Whoop, we use their sleep and HRV data to track circadian adjustment in real time and adjust the protocol if recovery is lagging.

The Griffin Travel Pack

One of the most tangible benefits of Griffin membership is the personalized travel pack your physician builds for you before each trip. This is not a generic first-aid kit from an airport pharmacy. It is a curated set of prescriptions and supplies tailored to your health profile, your destination, and the specific risks you are likely to encounter.

Each travel pack is tailored to the individual and the destination, but here are some common medications that may be included along with each member's specific prescriptions:

Depending on your destination, your pack may also include altitude medication (acetazolamide for elevations above 8,000 feet), malaria prophylaxis if you are traveling to an endemic region, and documentation including copies of all prescriptions, vaccination records, and a physician letter for any controlled medications. Every prescription comes in original pharmacy-labeled containers with your name, so there are no issues at customs.

We make sure every prescription you need is filled, labeled, and ready before you leave. Give us about two weeks before your travel date so we can tailor your pack to your destination and health profile. If your trip comes together quickly, reach out as soon as you can and we will do our best to accommodate.

Your Griffin Physician Travels With You

In traditional primary care, "call your doctor" from a foreign time zone means navigating a phone tree, leaving a message, and waiting days for a callback. For Griffin members, it means texting, calling, or messaging your physician directly. No phone trees, no hold queues. Time zone differences are managed, and urgent messages get responses regardless of the hour.

This matters because most travel health problems do not require an emergency room. Traveler's diarrhea, respiratory infections, UTIs, food poisoning, medication questions, skin reactions, and chronic condition flares can usually be managed remotely using the prescriptions in your travel pack and your physician's clinical guidance. Your physician already knows your history, your medications, and what you are carrying, so there is no cold-start problem when you call from overseas.

When you do need local care, we coordinate. Your Griffin physician can communicate with treating teams abroad, share your medical records, flag medication interactions, and ensure that any findings are integrated into your care plan when you return home. For members traveling in non-English-speaking countries, we can provide clinical notes and medication summaries in the local language so local providers have the context they need.

Medical Evacuation and MedJet

For serious emergencies abroad, not all international hospitals have the same capabilities. Medical evacuations can cost $25,000 to $250,000 or more, and standard health insurance almost never covers them.

Griffin Concierge Medical has partnered with MedJet to offer our members a 20% discount on medical transport membership. MedJet covers medical evacuation to the hospital of your choice in your home country, rather than just the nearest adequate facility. If you travel internationally more than once or twice a year, this coverage is worth considering.

If evacuation is needed, your Griffin physician coordinates with the receiving hospital, provides your medical records, and ensures continuity of care throughout the transfer.

In-Flight Health: The Overlooked Hours

Long-haul flights present their own set of health considerations that most travelers ignore:

• Deep vein thrombosis (DVT). Prolonged immobility on flights longer than four hours increases clotting risk. Move your legs regularly, do calf exercises in your seat, walk the aisle every 1-2 hours, and stay hydrated. For members with elevated DVT risk factors (prior clot history, oral contraceptive use, recent surgery, clotting disorders), we may recommend compression stockings or pre-flight low-molecular-weight heparin.
• Dehydration. Cabin humidity typically runs 10-20% - drier than most deserts. This accelerates dehydration and exacerbates jet lag symptoms. Drink water consistently throughout the flight and bring electrolyte packets. Avoid alcohol, which compounds dehydration and disrupts sleep quality.
• Respiratory illness. Aircraft cabin air is recirculated through HEPA filters, but proximity to other passengers in a confined space increases respiratory infection risk. Hand hygiene, avoiding touching your face, and considering a KN95 mask during high-transmission periods are reasonable precautions.
• Ear and sinus barotrauma. For members prone to ear or sinus pressure during descent, a nasal decongestant spray 30 minutes before landing can prevent painful pressure buildup.

Whether you are heading to Europe for two weeks or Southeast Asia for a month, your Griffin physician and patient care coordinator are here to make sure you travel prepared. Share your travel plans with us as early as possible and we will handle the rest: prescriptions, vaccines, travel pack, and a plan for staying connected while you are away. Contact your patient care coordinator, reach out through the Griffin app, or bring it up at your next visit.

Frequently Asked Questions

How far in advance should I see my doctor before international travel?

Ideally 4-6 weeks before departure. Some travel vaccines require multiple doses or take time to reach full efficacy. Certain destinations require proof of vaccination (such as yellow fever) that must be documented on an International Certificate of Vaccination. If your trip is less than four weeks away, it's still worth consulting - most preparations can be accelerated.

What vaccines do I need for international travel?

Required and recommended vaccines depend entirely on your destination, duration, activities, and personal health history. Common travel vaccines include hepatitis A and B, typhoid, yellow fever, Japanese encephalitis, meningococcal vaccine, and rabies pre-exposure prophylaxis. Your physician should also verify that routine immunizations (Tdap, MMR, influenza, COVID-19) are current. Griffin Concierge Medical provides destination-specific recommendations based on CDC and WHO guidelines.

What is the best way to manage jet lag?

Jet lag management involves strategic light exposure, melatonin timing, and sleep scheduling. For eastward travel, begin shifting your sleep schedule earlier several days before departure. Use morning bright light and evening melatonin at your destination to accelerate circadian adjustment. For westward travel, extend your day with evening light exposure. Staying hydrated, avoiding alcohol during flights, and strategic caffeine use also help. Your physician can provide a personalized protocol based on the specific time zones involved.

Do I need malaria prevention medication?

Malaria prophylaxis is recommended for travel to endemic regions in sub-Saharan Africa, South Asia, Southeast Asia, Central and South America, and parts of the Middle East. Options include atovaquone-proguanil (Malarone), doxycycline, and mefloquine, each with different dosing schedules and side effect profiles. Your physician can recommend the best option based on the specific malaria species in your destination and your individual health factors.

What prescriptions should I carry when traveling internationally?

At Griffin Concierge Medical, we commonly provide travel prescriptions including antibiotics for traveler's diarrhea, anti-nausea medication, a broad-spectrum antibiotic for respiratory or skin infections, and altitude sickness prevention for high-elevation destinations. Malaria prophylaxis is added when traveling to endemic regions. All prescriptions come in original pharmacy-labeled containers with clear instructions.

Should I get travel health insurance?

Yes, strongly recommended. Most domestic health insurance plans provide limited or no coverage outside the United States. Travel health insurance should cover emergency medical treatment, medical evacuation (which can cost $50,000-$250,000+ depending on location), and repatriation. For frequent international travelers, an annual travel health policy is often more cost-effective than per-trip coverage.
