U.S. Law: U.S. government officials have stated that individuals who order non-controlled prescription drugs from Canada or other foreign sources (up to a three-month supply) for their own use are not being pursued or prosecuted. However, it is technically not legal for individuals to import most prescription drugs.
Coverage by Insurance: For a drug to be reimbursable from a health reimbursement account or flexible spending account it must be approved for sale in the U.S. and prescribed by a licensed U.S. physician, although drugs which you personally import are typically not reimbursable. If you have pharmacy insurance coverage, you may want to check with your benefits administrator to determine whether drugs ordered from outside the U.S. will be covered or reimbursed.
