FDA Regulations For Bringing in Medications From a Foreign Country
A 1998 amendment allows a United States resident to import up to 50 dosage units of a controlled medication without a valid prescription at an international land border. These medications must be declared upon arrival, be for your own personal use and in their original container. However, travelers should be aware that drug products which are not approved by the U.S. Food and Drug Administration (FDA) may not be acceptable for such importation.
It is against the law not to properly declare imported medications to U.S. Customs.
It is important to have medications in the originally-dispensed container.
Canadian law requires that Canadian pharmacies can only fill prescriptions written by a Canadian Doctor. This generally requires a trip to Canada, although some people like Tony have been able to fill prescriptions by mail.
