Travelan – Preventing Travellers’ Diarrhoea Overseas
Page Contents
Nobody tells you one bad meal can end your trip before it’s started
Nobody tells you that the thing that could ruin your dream trip isn’t a missed flight, a lost bag, or even a dodgy Airbnb. It’s dinner. One plate of something, somewhere, on day three – and suddenly your once-in-a-lifetime adventure through night markets and temple ruins becomes a very intimate relationship with a hotel bathroom.
I’ve watched this play out from the sidelines several times with my husband.
He’s been laid up – properly, miserably unwell – more than once during trips through Asia. Not “delicate tummy for a day” unwell. The kind of unwell where you cancel plans, cancel meals, even cancel trips and spend a chunk of a trip you paid good money for staring at hotel ceiling tiles instead of temple carvings. Read how we were evacuated in Tibet due to being unwell due to food related issues. Following too many episodes to even be able to count, he discovered Travelan and he has not looked back!

Now it’s just part of how we pack. Passports, chargers, Travelan. Every time we’re heading to Asia, it’s already in his kit before I’ve even finished my own packing list.
This article shares Travelan as a product our family has personally relied on while travelling through Asia. It is general information only and not personal medical advice – always read the label, follow the directions for use and speak with your pharmacist or GP about what’s appropriate for your own health before you travel.
What Travelan actually Is
Travelan is an over-the-counter oral medication, available at pharmacies across Australia, designed to help reduce the risk of travellers’ diarrhoea before it starts – rather than just treating it once it’s already wrecked your day. It’s made from hyperimmune bovine colostrum containing natural anti-E. coli antibodies and it’s taken as a caplet before meals.
The way it works is clever. Rather than doing something to your gut directly, it works in the gastrointestinal tract itself. If you happen to eat or drink something contaminated with E. coli – which is one of the most common causes of travellers’ diarrhoea, alongside other bugs picked up through food and water – Travelan is designed to bind to the bacteria and the toxins they produce, stopping them from attaching to the intestinal wall in the first place.
It’s not a cure. It’s not a substitute for common-sense hygiene – you still want to be sensible about where you eat and drink. But as a preventative layer, sitting quietly in the background while you actually enjoy your trip, it’s built for exactly the situations solo and group women travellers find themselves in most – new food stalls, unfamiliar water, a schedule packed too tight to lose a day to being sick.
Why this matters more when you’re travelling solo or in a small group
If you’re travelling with a partner and things go wrong, there’s someone to fetch you water, cancel the excursion and sit with you. If you’re a woman travelling solo, or heading off with a small group of women you’ve only just met, being unwell is different. There’s no one whose job it is to look after you. You’re managing it – and the itinerary and everyone else’s plans – largely on your own.
That’s precisely the gap something like Travelan is designed to sit in. It’s not about being paranoid or overly cautious. It’s about giving yourself one less thing to worry about so you can actually be present for the trip you saved for and looked forward to – the street food stalls in Georgetown, the market breakfasts before a trek, the meals you didn’t plan for but said yes to anyway because that’s half the joy of travelling.
Food safety isn’t something anyone wants to dwell on before a trip. But being able to say yes to the food, rather than eating cautiously out of fear, is part of what makes a trip feel like an adventure instead of an exercise in risk management.
Where it fits on your packing list
For destinations across Asia, Africa and South America in particular – where street food and market meals are half the reason you’re going – Travelan is worth discussing with your pharmacist or GP before you fly, alongside your usual pre-travel health prep. It’s available at major pharmacies Australia-wide and you can also buy it here online, so it’s an easy addition to your pre-trip pharmacy run alongside your usual sunscreen and insect repellent stock-up.
As always, read the label and follow the directions for use and if diarrhoea symptoms do occur and persist beyond 48 hours, see a healthcare practitioner rather than relying on any preventative product alone. This is general information, not personal medical advice – what’s right for your own gut, medication list and health history is worth a quick chat with your pharmacist before you go.
The bigger picture
None of this is about scaring you off street food or market stalls – quite the opposite. Some of the best meals of my life have come from places with no menu in English and a queue of locals out front. The goal is simply to stack the odds in your favour, so a dodgy stomach doesn’t get to decide how your trip goes.
If you’re planning your own adventure through Asia – whether that’s our Sri Lanka trip, exploring Malaysia solo, trekking in the Andes or somewhere further afield – a little preventative planning goes a long way toward making sure it’s the food stalls you remember, not the bathroom.
