The Food and Drug Administration policy on theimportation of prescription drugspurchased abroad is fairly clear.

Under most circumstances,federal guidelines prohibit the importation of such drugs for personal use, largely because medications sold in another country have not been approved by the FDA for use in this country.

If you’ve been honest in filling out your Customs declaration and have listed the foreign-bought medications, Customs legally could seize the drugs. However, the tendency is to look the other way if the drug in question is not a controlled substance and if the amount purchased doesn’t exceed a 90-day supply.

Certain Drugs Are Allowed

However, there are a few other conditions that govern the policy on such drugs.

  • The medication must not pose an unreasonable risk.
  • You must attest — in writing — that the drug is strictly for your personal use.
  • The amount of drug brought into the country should not exceed a three-month supply. If the drug is to be taken twice daily, that would mean no more than 180 units would be allowed.

Risk of Prescription Drugs being Confiscated by United States Customs

The FDA’s guidelines apply toprescription medications that are brought in from any country outside the United States, including Canada.

While most over-the-counter medications can be imported in amounts consistent with personal use, this policy does not extend to products that are OTC in other countries but available only by prescription in the United States.
