Experts reveal 5 common travel mistakes that could damage your medications

Travelers often focus on packing clothes, passports, and travel essentials, but experts say where medications are stored during a trip can be just as important.

Improper storage can expose medications to heat, humidity, or physical damage, potentially reducing their effectiveness when they are needed most. Health experts advise keeping medications in stable conditions and in their original packaging whenever possible.

Here are five common places travelers should avoid storing medications—and safer alternatives to consider.

Loose in a Plastic Bag

While combining multiple medications into a single plastic bag may seem convenient, experts warn that doing so can create confusion and increase the risk of taking the wrong medication or dosage, particularly during hectic travel schedules.

Loose pills are also more vulnerable to crushing or damage.

Instead, travelers are advised to keep medications in their original prescription bottles or packaging. Original containers can also help avoid complications during airport security screenings. Those who use pill organizers may want to fill them after arriving at their destination.

Hotel Bathrooms

Bathrooms are a common storage spot for medications, but experts say they are among the worst places to keep them.

The heat and humidity generated by showers and baths can degrade certain medications over time, potentially reducing their potency. Moisture exposure can also damage pills and packaging.

A bedroom drawer, dry countertop, or hotel safe is generally considered a safer alternative, particularly for controlled medications.

Checked Luggage

Medical professionals recommend keeping medications out of checked baggage whenever possible.

Checked luggage can be exposed to fluctuating temperatures and weather conditions during transit. In addition, lost or delayed baggage could leave travelers without access to essential medications.

Instead, medications should be packed in carry-on luggage, where they remain accessible and protected throughout the journey.

Direct Sunlight

Exposure to direct sunlight can raise medication temperatures and contribute to chemical degradation, potentially affecting effectiveness.

Experts recommend keeping medications away from windows in hotel rooms, vehicles, and other areas where they may be exposed to prolonged sunlight.

When outdoors, medications should remain covered and stored in a bag or other protective container.

Hot Cars

Leaving medications inside a parked vehicle can expose them to extreme temperatures, especially during warmer months.

Glove compartments, trunks, floorboards, and areas near heating vents can become particularly hot, creating conditions that may damage medications.

Experts suggest carrying medications in a small personal bag and keeping them away from direct sunlight and heat sources while traveling. 

For temperature-sensitive medications such as insulin or GLP-1 injections, insulated carriers or cold packs may help maintain appropriate storage conditions.
