How to Safely Ship Insulin and Refrigerated Medications: Legal Rules, Packing Tips, and Best Practices

Quick Answer: Shipping insulin and refrigerated medications is highly regulated and usually limited to DEA-registered entities. If allowed, medicines must be packed in insulated coolers with gel packs to stay cold during transit. Always check legal requirements and shipping company guidelines before mailing.

Mailing prescription drugs to your loved ones seems like a good idea in many situations: your friend has forgotten his insulin at home, or your daughter has left for a 2-week holiday without her medication. However, shipping prescribed drugs in the U.S. is very restricted, and only a few people or entities can legally do so.

Shipping prescribed drugs nationally

According to the U.S. Postal Service, you can only send prescription drugs through the mail if you are an entity registered by the Drug Enforcement Administration (DEA). For example, drug manufacturers, pharmacies, medical practitioners, or other authorized drug dispensers generally fall into that category. I

t is illegal for an individual to mail prescription drugs in the U.S.A., even if it's within your state. It does not matter if it's a drug that someone has forgotten at your place, even if you have convincing documentation that you're doing it in good faith and it's a widely used medicine like insulin or others. The only exceptions in which you're allowed to ship prescription medicines are:

• If you or the recipient are exempted from DEA registration (military, law enforcement, or civil defense).
• If you're mailing a drug back to its manufacturer (or the pharmacy).

Shipping prescribed drugs internationally

Similar restrictions apply to shipping prescription medications internationally. First, you can only ship drugs to the U.S. if it's officially approved by the Food and Drug Administration (FDA). If you're willing to ship drugs outside of the U.S., you must comply with the destination country's regulations about drug importation. Note that in most countries, it's illegal for individuals to import prescription drugs via mail. Instead, it must be sent by an official company (pharmacy, drug manufacturer, etc.).
