When travelling to Norway, you may bring medicines for personal use. There are limits to the amounts you can bring with you.
It is the Norwegian Medicines Agency that is responsible for regulations concerning medicines. The rules vary depending on whether you are travelling to or from Norway, and they depend on the type of medicine. There are also different rules for what you may bring on holiday and what you may receive as a shipment.
