Bringing medication to Belgium: three months, a certificate, and one hard prohibition

Belgium's rules for travellers' medication come from the FAMHP — the Federal Agency for Medicines and Health Products — and key off the Royal Decree of 6 September 2017 regulating narcotic and psychotropic substances. If your medicine contains a listed substance, you need "an official accompanying document proving that you were prescribed these medicines as part of a medical treatment."

The agency's own examples map neatly onto the medicine cabinets this site's readers actually carry: "sleep-inducing medicines and sedatives; strong analgesics (e.g. analgesics containing morphine); medicines for the treatment of ADHD (e.g. medicines containing the active substance methylphenidate); medicines used in substitution therapy (e.g. methadone, buprenorphine)."

Ordinary medicines outside the decree's lists — blood-pressure treatment, antibiotics, contraception — carry no special Belgian formality, though original packaging and a pharmacy list remain the sensible defaults for anything crossing a border. When in doubt, the agency's named advisers are your doctor or pharmacist, or its published substance list.

The FAMHP splits arrivals into two groups, and the paperwork differs.

Living in another Schengen country: the instrument is a Schengen declaration validated by the competent authorities of the country where you are domiciled — the standardised certificate our Schengen certificate guide explains. You obtain it at home, before travelling, from your own country's issuing authority.

Living outside the Schengen area — the United States or the United Kingdom: you must justify the medicines with "a valid medical prescription or a certificate validated by the government." In practice that means travelling with the prescription itself and, where your origin country issues one, its validated export certificate; the International Narcotics Control Board publishes per-country requirements.

Two limits apply to everyone. The supply may not exceed three months of treatment. And if your stay runs past thirty days — or past whatever limit your origin country's document carries — the agency's instruction is to "contact a doctor in Belgium" so the treatment is followed up correctly. That is not bureaucratic filler: it is the designed handover point from imported supply to a Belgian prescriber.

One FAMHP sentence deserves its own section, because it is the rule expats break innocently: "It is forbidden to have narcotic or psychotropic substances sent to Belgium."

The scenario is always the same. The three-month supply runs low, a refill is sitting at a US pharmacy, and a family member offers to post it. That parcel is illegal at the Belgian border — not irregular, not subject to a form, forbidden. The same applies to mail-order pharmacies shipping internationally.

The lawful route is the one the agency built into its own rules: before month three, be in front of a Belgian doctor. As a resident you will in any case have registered at your commune and affiliated to a mutualité — and once you are in that system, a Belgian GP can assess your treatment and prescribe its continuation domestically, reimbursed like any other care, with no parcels and no border risk. The three-month cap and the see-a-doctor instruction are two halves of one design: Belgium gives you a bridge, not a pipeline.
