To answer Southey's question on European Health Insurance Cards:
Medical information for Uk nationals traveling to Norway with EHIC
Doctors
There will be a standard fee. Ensure you consult a doctor who has a reimbursement arrangement with the NAV (Norwegian Employment and Organization). This includes medical practitioners. This is non-refundable in Norway but you may be able to seek reimbursement when you are back in the UK.
Dentists
You will usually have to pay the full cost of any dental treatment.
This is non-refundable in Norway but you may be able to seek reimbursement when you are back in the UK.
Hospital treatment
Charges are payable for specialist consultations and outpatient treatment. This is non-refundable in Norway but you may be able to seek reimbursement when you are back in the UK.
Normally, a doctor will refer you to hospital. In an emergency, you can get treatment from the nearest public hospital. Inpatient treatment, including necessary medication, is free of charge.
Prescriptions
You will have to pay for most prescribed medicines. However, if you are prescribed medicines by a doctor on a blue prescription (generally medication for chronic conditions), you should be charged less.
Hope this helps
