Prescription drugs could be illegal and confiscated while traveling overseas — here’s which to leave at home: experts

These meds won’t fly.

A pharmaceutical expert for Fox News is warning about what medications can and cannot be packed for trips overseas. The advice comes ahead of what’s anticipated to be an explosive summer of air travel and applies to the 77% of Americans who plan to travel with medications, according to a recent SingleCare survey.

“Generally, medications that have a high potential for abuse or dependency are more likely to face strict regulations,” pharmaceutical researcher Jennifer Bourgeois told Fox News Digital, stressing that controlled substances typically top the list.

“Bringing prohibited medications into a foreign country can have the potential for serious consequences, such as confiscation of medications, fines and possible arrest.”

Bourgeois specifically flagged painkillers like oxycodone, hydrocodone, codeine and tramadol along with amphetamines like Adderall, plus nervous flyer favorite Xanax, a benzodiazepine.

“Cannabis and cannabis-derived products” might also cause unwanted drama as they remain illegal in many parts of the globe.

The best way to make it through airport security and abroad with no issues is by first and foremost keeping medications in their clearly distinguishable, original packaging with the patient’s name present.

“Carry only the quantity you need for the duration of your trip, plus a small buffer,” Bourgeois said.

“Exceeding personal use quantities can raise suspicions.”

While overseas, check the nation’s over-the-counter rules — embassy or consulate websites are great sources for this — and only ever buy from legitimate pharmacies as well.

“You may also consult with your doctor, pharmacist or travel agent, who may be able to provide advice tailored to your destination,” she added.

“For instance, many countries allow only a 30-day supply of certain medicines, and require that you carry a prescription or a medical certificate from your health care provider.”

Bourgeois also said it’s especially important to give your home pharmacy at least two weeks’ notice if you may need a prescription refill while away.

“The pharmacist may need to request refills or a ‘vacation override’ from your insurance,” Bourgeois noted.
