Customs and Personal-Import Rules for Prescription Drugs
Bringing prescription drugs into the U.S. from abroad, including GLP-1 drugs, is subject to specific and often misunderstood federal rules.

Federal law generally restricts personal importation of prescription drugs into the U.S. to narrow circumstances, even when the drug is legally purchased abroad — a common point of confusion for patients considering cross-border purchasing to save money.
Limited enforcement discretion isn't a legal guarantee
U.S. Customs and the FDA have historically exercised discretion around small, personal-use quantities in some cases, but this discretion isn't a legal right, isn't guaranteed case by case, and doesn't apply to bulk quantities or products intended for resale.
State-level importation programs are different
Separate from personal importation, some states have pursued federally authorized bulk drug importation programs (from Canada, for example) at the pharmacy or state level — a distinct, regulated pathway rather than an individual traveler bringing medication across the border.
