Detailed description
For trips of up to 30 days to member states of the Schengen Agreement, you may bring medically prescribed narcotics. You must carry a certificate completed by your treating physician. This certificate must be authenticated before your trip. You need a separate certificate for each prescribed narcotic. The certificate is valid for a maximum of 30 days. This regulation also applies if you are carrying narcotics that are available by prescription in your country of origin but not in your destination country.
Only you personally are permitted to carry the narcotics, along with the required documentation. No one authorized by you may carry them.
