Personal drug imports are generally permitted but not technically legal.

Since 2000, millions of Americans with inadequate or no drug coverage, as well as those seeking critical medications that are not available domestically, have purchased medication from foreign pharmacies, mostly using online pharmacies. This process is known as personal drug importation. The U.S. government generally does not stop individuals from importing medication for their own use (usually up to a three-month supply of non-controlled drugs), however, under most circumstances, it is technically illegal. According to the FDA, no one has ever been prosecuted for personal drug importation (importing small quantities of medication for personal use).

While the law allows the FDA and the U.S. Customs and Border Patrol to detain and refuse international prescription orders arriving through the mail, less than one percent are actually stopped. In these cases, under U.S. law, you will be informed by the FDA that your drug order has been detained or refused and that you are allowed to challenge their decision to take away your medication to try and have it released.  The U.S FDA regulates the safety and efficacy of medications sold in U.S. pharmacies. Medications dispensed from outside the U.S. are regulated for safety and efficacy by pharmaceutical/pharmacy regulatory authorities in other countries.
