How to Travel with Biologic Medications
A complete guide to keeping your biologic safe during flights, road trips, and international travel
Key Takeaways
- Always carry your biologic in your carry-on luggage — not checked bags
- Use a medical travel cooler with gel packs (never dry ice directly against medication)
- Carry a letter from your prescriber for airport security and customs
- Most biologics can tolerate short periods at room temperature — check your medication's specific limit
- Notify BiologicHealthPlus in advance to coordinate delivery timing around your travel
Before You Travel: Preparation Checklist
- ✅ Request a letter from your prescriber explaining your diagnosis and medication
- ✅ Purchase a medical travel cooler with gel refrigerant packs
- ✅ Know your medication's room temperature tolerance window
- ✅ Carry enough medication for your trip plus extra in case of delays
- ✅ Research your destination's refrigeration options (hotel mini-fridge, medical facilities)
- ✅ If traveling internationally, research import requirements for your destination country
- ✅ Notify BiologicHealthPlus of travel plans to adjust delivery schedule
Airport Security and TSA
Injectable medications and necessary supplies (syringes, needles, auto-injector pens) are permitted through TSA security. Declare your medication and cooling supplies at the checkpoint. Gel packs that are frozen or slushy may be permitted; fully liquid gel packs may not pass the liquid rule without medical documentation.
Your prescriber's letter explaining your medication will help security officers understand the medical necessity of your cooler and supplies.
