How do you bring prescription drugs over the border into the US from Mexico?
<|assistant|>
Prescription drugs may be brought over the border into the US from Mexico by individuals possessing a valid prescription from a licensed US provider. Any medications crossing the border must be declared to Customs and Border Protection upon entry into the United States. In most cases, the individual taking the medication will need to fill out a form verifying their identification, the medication’s name and purpose, the quantity being carried and intended destination in the US. In addition, some medications require a certificate of authenticity for importation.
