Traveling internationally? It could be illegal to bring along these medications, according to a pharmacist

As summer travel season gears up, 77% of Americans expect to pack a prescription medication for the trip — but nearly half don’t check to see whether it’s even legal to bring those meds into other countries.

Additionally, more than a quarter of Americans have had medications confiscated during international travel, according to a May 2024 survey of 1,048 respondents by SingleCare, a free prescription savings service.

"Certain medications that are commonly prescribed in the United States might be illegal or strictly regulated in other countries," Dr. Jennifer Bourgeois, PharmD, a pharmacy and health expert based in Dallas-Fort Worth, told Fox News Digital.

Here are some important details on this topic.  

4 types of medications that may be illegal for international travel

"Generally, medications that have a high potential for abuse or dependency are more likely to face strict regulations," Bourgeois warned.

These include controlled substances, which are tightly regulated because of their potential for addiction and misuse, she said.

Stimulants, which are used for conditions such as ADHD and are considered illegal in some countries, are also included in that category.

Bourgeois shared the following list of prescription drugs that may be illegal to transport across the border.

No. 1: Narcotics and opioids

Medications such as oxycodone, hydrocodone and codeine are heavily regulated or banned in many countries due to their potential for abuse, according to Bourgeois.

No. 2: Psychotropic drugs

Drugs for mental health conditions, such as amphetamines (Adderall), benzodiazepines (Xanax) and certain antidepressants, may be restricted.

No. 3: Medicinal cannabis

"Even if they are legal in some U.S. states, cannabis and cannabis-derived products are illegal in many countries," Bourgeois cautioned.

No. 4: Strong painkillers

Some countries restrict strong painkillers, such as tramadol, which is an opioid sold under the brand names ConZip and Ultram, to treat moderate to severe pain.

How to check legality before traveling

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

"In severe cases, travelers may be detained, prosecuted and even jailed."

Legal issues can also lead to delays and complications in travel plans, she added.

Before packing your prescriptions when traveling abroad, Bourgeois recommends checking your destination country’s embassy or consulate websites and laws regarding medication. 

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

If there are specific restrictions for your medication in the country you plan to visit, it’s best to follow the directions from the country’s embassy so you can continue to take your medication while traveling. 

"Bringing prohibited medications into a foreign country can have the potential for serious consequences."

"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," said Bourgeois.

If you know that you’ll need a refill of your prescription while you are away, check with your pharmacy two weeks before you leave.

The U.S. Centers for Disease Control and Prevention (CDC) recommends making an appointment with your health care provider or a travel health specialist at least one month before you leave, as stated on its website.

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

If your medication is absolutely not allowed in the destination country, Bourgeois suggests consulting with your health care provider to discuss alternatives and potential adjustments to your treatment plan.

What to know before packing prescriptions

Even if your medications are permitted in the country you’re visiting, it’s still important to follow some basic guidelines when traveling internationally, according to Bourgeois.

First, it’s important to always have a copy of your prescription or a medical document signed by your doctor explaining why the medication is essential for you to have.

"Exceeding personal use quantities can raise suspicions."

On its website, the CDC also recommends leaving a copy of your prescriptions at home with a family member or friend in case you lose your copy or need an emergency refill.

"Also, keep all medications in their original packaging to clearly display the prescription label," Bourgeois advised.

Additionally, she said, make sure the name on the prescription matches the name on your passport.

"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."

Also, be sure to declare your medications at customs if required by the destination country, she said.

5 additional medication travel tips

Bourgeois shared the following additional things to consider when bringing medication across the border.

No. 1: Keep time zones in mind

"Taking daily medications for chronic conditions can be confusing when you travel across the world," she cautioned.

"In severe cases, travelers may be detained, prosecuted and even jailed."

"Pay attention to time-zone differences and take the medication according to your last dose, not the local time of day."

No. 2: Check OTC rules

"It is important to check your destination country's laws for over-the-counter medications, too," Bourgeois said.

"Carry only the quantity [of medicine] you need for the duration of your trip, plus a small buffer," an expert advised. "Exceeding personal use quantities can raise suspicions." (iStock)

"For example, pseudoephedrine — commonly known as the brand drug Sudafed, which is purchased over the counter in the U.S. — is prohibited in Japan and Mexico."

No. 3: Don’t buy from non-pharmacy sellers

If you are traveling internationally, don’t buy any medications that are not sold at the pharmacy, Bourgeois said.

Common over-the-counter medications for travel include antidiarrheals, motion sickness meds, allergy medicines and medications for pain and fever.

No. 5: Understand disease risks

If you are traveling outside the U.S., it is important to understand the risk of diseases in the countries you plan to visit. 

"Diseases such as Hepatitis A, yellow fever and typhoid can be prevented through vaccinations," Bourgeois said.

"Talk to your pharmacist about vaccine-preventable diseases and request a travel health consultation to ensure you are protected," she continued. 

"It’s vital that you do not wait until the last minute to get your vaccinations, as it typically takes up to 14 days for antibodies to build."
