How do I bring my prescription medicine into the United States?
NARCOTICS AND DANGEROUS DRUGS ARE PROHIBITED ENTRY. THERE ARE SEVERE PENALTIES IF IMPORTED.
A traveler requiring medicines containing habit-forming drugs or narcotics (e.g. cough medicine, diuretics, heart drugs, tranquilizers, sleeping pills, depressants, stimulants, etc.) should:
Have all drugs, medicines, and similar products properly identified;
Carry only the quantity that might normally be used by an individual having a health problem requiring such drugs or medicine:
Have either a prescription or written statement from your personal physician that the medicine is being used under a doctor's direction and is necessary for your physical well-being while traveling.
Medication can be sent by post if the prescription or doctor's letter is included. A notation should be placed on the outside of the parcel stating, for example, "DOCTOR'S LETTER ATTACHED."
