New federal regulations may affect Americans who import prescription medications from Canada and other countries. Some US consumers have been using Canadian mail-order pharmacies to save money on medications that are more expensive in the US.

These consumers are now concerned about new US Customs requirements set to take effect later this month. The requirements have raised concerns among patients and pharmacy operators about the impact on their access to affordable medications.

Further details on the regulations and their potential impact are available, including the story of a patient who relies on a Canadian pharmacy for a generic blood thinner medication.
