Medication safety after exposure to airport x-rays
Medication safety is a crucial aspect of travel preparation, especially when it comes to exposure to airport X-rays. Here are some insights and guidelines to ensure medication safety after passing through airport X-rays:
Impact of Airport X-rays on Medications:
According to experts, the X-ray machines used in airport security screenings emit low levels of radiation that are generally considered safe for medications. This radiation dose is significantly lower than what is required for food preservation or parasite destruction. The FDA has confirmed that food, drinks, and medications passed through X-ray security scanning should not cause any harm or adverse effects. Additionally, the FDA's Center for Devices and Radiological Health (CDRH) ensures that all X-ray systems used for security purposes are built to safely utilise radiation.
Regulations and Guidelines:
Before travelling with prescription drugs and medications, it is essential to familiarise yourself with the regulations of the country you are visiting. Here are some general guidelines to follow:
- Always check with your pharmacist or the medication manufacturer if you have concerns about X-ray exposure affecting your medication.
- Keep all medications in your carry-on luggage to avoid potential damage from checked baggage scanners.
- If you have concerns about X-ray exposure, you have the right to request a visual inspection of your medications. This request must be made before sending any items through the X-ray machine, and it's helpful to keep your medications separate from other carry-on items to facilitate the process.
- For liquid medications, inform a TSA official at the start of the screening process. Different countries have specific regulations regarding liquid medications. For example, the UK requires proof, such as a letter from a doctor or a copy of the prescription, for liquid medications exceeding 100 millilitres (3.38 ounces).
- Some countries have regulations for controlled substances, such as cannabis, codeine, fentanyl, and testosterone. These substances may require additional documentation and must be in carry-on baggage.
- If your medication requires refrigeration or special storage, make the necessary arrangements in advance, especially if you are flying.
Alternative Screening Methods:
If you prefer to avoid X-ray screening altogether, there are alternative methods available:
- Manual Inspection: You can request a manual inspection or visual inspection of your medications by a TSA agent. This option is allowed by the Federal Aviation Administration regulations for domestic flights.
- Alternative Screening Equipment: Some airport security systems use non-ionizing radiation, such as metal detectors, to scan for prohibited items. These devices do not expose travellers to high levels of radiation.
In conclusion, while airport X-ray exposure is generally considered safe for medications, travellers can take proactive steps to ensure medication safety. Being informed about regulations, requesting alternative inspection methods, and properly storing medications can help maintain the effectiveness and safety of your medications during air travel.

Regulations for carrying prescription drugs through airport security
While it's true that every item brought onto an airplane must be screened, you should be able to bring prescription drugs on your flight without difficulty. Here are some regulations for carrying prescription drugs through airport security:
Liquid Medications
According to the Transportation Security Administration (TSA), passengers are allowed to carry liquid medications in "reasonable quantities for the flight." Liquid medications do not have to be placed in a zip-top bag, unlike other liquids, and they will be subject to additional screening. If your liquid prescription medications come in larger containers or bottles, pack them separately in your carry-on luggage.
Medications in Solid Form
Unlimited amounts of pills or medications in solid form are permitted through carry-on baggage checkpoints or in checked bags. The TSA does not require passengers to have medications in prescription bottles, but states have individual laws regarding the labelling of prescription medication.
Controlled Substances
Some countries, such as the UK, have strict regulations for controlled substances, which may include cannabis, codeine, fentanyl, and testosterone. Controlled substances must be in carry-on baggage and accompanied by a letter of proof that each medicine was prescribed for the traveller. This letter must include the traveller's name, dates of travel, the prescribing doctor's signature, and a list of the medications with their respective dosages.
X-Ray Screening
Some travellers may be concerned about the potential effects of baggage X-rays on their medications. However, most medications are not affected by the low doses of radiation emitted by airport screening machines. If a drug could be affected by X-ray screening, it would likely be indicated on the label or package insert. If you are still concerned, you can request a manual inspection of your carry-on bag, which the TSA states you have the right to do.
Additional Considerations
It is recommended to carry only the prescription drugs and medical liquids you need during your flight in your carry-on bag. This ensures that you have access to your medications during the flight and avoids the risk of losing them in checked baggage. Additionally, consider contacting TSA Cares at least 72 hours before your flight if you have any specific questions or concerns about packing and presenting your prescription medications at the screening checkpoint.

Liquid medication rules at airports
Medications are usually allowed through airport security x-ray machines. The x-ray machines emit low levels of radiation that have not been consistently shown to affect medications. If a drug is affected by x-ray screening, it will be indicated on the label or package insert. If you are concerned, you can request a TSA agent to perform a security check by hand.
Liquid medications are subject to the same rules as other liquids at airport security. You are allowed to bring a quart-sized bag of liquids, including liquid medications, in your carry-on luggage. Each liquid item must be in a travel-sized container that is 3.4 ounces (100ml) or less. Any liquid that is over this amount must be packed in your checked baggage. However, the TSA does allow larger amounts of medically necessary liquids, gels, and aerosols, but these must be declared to TSA officers at the checkpoint for inspection.
If you have liquid medications that require refrigeration or injection via syringes, you may need to make special travel arrangements. It is recommended to check with your pharmacist before travelling with prescriptions to ensure that your medications are travel-ready. For example, you may need to keep your medications in a temperature-controlled bag or have access to an ice machine or ice packs during your trip.
Additionally, if you are travelling with liquid medications that are duty-free, you may carry these in your carry-on bag if they were purchased internationally and you are travelling to the United States with a connecting flight. The liquids must be packed in a transparent, secure, tamper-evident bag by the retailer and not show signs of tampering when presented to TSA for screening.

How to request a visual inspection of your medication
Although medications are usually screened by X-ray at airports, passengers can request a visual inspection of their medication instead. This request must be made before any items are sent through the X-ray tunnel.
- Keep your medication easily accessible: When preparing to go through security, ensure that your medication is easily accessible and separate from your other carry-on items. This could be in a pouch or bag that can be quickly removed for inspection.
- Inform the TSA officer: Before placing your items on the conveyor belt, inform the TSA officer that you would like a visual inspection of your medication. You can simply state your preference for a manual check instead of X-ray screening.
- Provide relevant documentation: If you are carrying prescription medication, it is advisable to have a copy of your prescription or a letter from your doctor stating the details of your medication. This documentation can help expedite the inspection process and ensure that your medication is properly identified.
- Be prepared for additional screening: Keep in mind that requesting a visual inspection may result in additional screening procedures. TSA officers may open and physically inspect your medication and carry-on baggage. They may also ask you to open containers or provide further information about your medication.
- Plan ahead for special considerations: If your medication requires special handling, such as refrigeration or injection via syringes, make sure to communicate this to the TSA officers. They will work with you to ensure that your medication is properly screened while adhering to any necessary storage or handling requirements.
- Stay informed about regulations: Different countries may have specific regulations regarding the amount and type of medication allowed. For example, the UK government requires proof, such as a doctor's letter or prescription, for liquid medications exceeding 100 milliliters (3.38 ounces). Familiarize yourself with the regulations of your departure and destination airports to ensure you comply with any special requirements.
Remember, while X-ray screening is generally considered safe for medications, you have the right to request a visual inspection if you have concerns. By following the above steps, you can ensure a smooth and efficient process when requesting a visual inspection of your medication at airport security.

The effects of extreme heat on medications
Medications are generally safe to pass through airport x-ray machines. The machines emit low levels of radiation that have not been consistently shown to affect medications. If there were any danger, it would be indicated on the label or package insert. The FDA, which oversees labelling, has stated that it knows of no drugs that have special instructions to avoid airport x-ray machines.
However, some medications are sensitive to extreme heat. High temperatures can degrade or damage certain medications, such as inhalers, EpiPens, and insulin. Heat can also increase skin sensitivity from sun exposure for those taking certain medications, such as some antifungals and antibiotics. Additionally, some medications can interfere with thermoregulation and/or fluid balance, amplifying the risk of harm from hot weather. For example, diuretics, some antipsychotics, some antidepressants, and some antihypertensive agents can increase the risk of dehydration and heat stroke.
Older patients and those with altered cognition are particularly vulnerable to the effects of extreme heat while taking certain medications. It is important for these individuals to have a point of contact to check on them and to be aware of the symptoms that may indicate drug interactions with heat.
To mitigate the effects of extreme heat on medications, patients can be counselled on how to best store their medications when temperatures are high. For example, using a temperature-controlled lunch bag or storing medications in a cool, dry place. When travelling, it is recommended to keep medications in a hotel room with access to a refrigerator or ice machine.
