The answer so far
A prescription from home does not automatically let you take a medicine into another country. Rules can depend on the substance, quantity, traveller and route. Check official requirements for departure, transit and destination, and contact the relevant embassy or authority if you need clarification.12

Identify the substance and route
Find the generic substance name, product name, form and quantity. Check the departure country, each country where you enter or transit, and your final destination. An authority may classify a product differently from a seller who calls it a supplement or peptide.12
Documents and permissions
Depending on the country and substance, you may need a prescription, clinician’s letter, certificate, permit or declaration. Do not assume a general allowance or Schengen document applies everywhere. Check the official guidance for your destination and circumstances, and allow time to obtain any permission.23
EU and Schengen: why the distinction matters
The European Union and the Schengen travel area do not have identical members. A Schengen certificate for certain controlled medicines is not a universal EU medicine passport.
For example, French Customs describes a particular authorisation for a person resident in France travelling to another Schengen country with a narcotic medicine. It gives that authorisation a maximum validity of 30 days. This is one way of obtaining a document and describes its validity; it is not permission for every substance or a universal allowance. Check the issuing authority and the rules for your exact route. See the France and Germany guides.45
If the medicine is restricted or prohibited
A seller offering international shipping, or an airport letting an item through security, does not establish that it is legal at your destination. The CDC advises discussing alternatives with a health professional before travel if the destination does not allow the medicine. Ask the responsible authority about your particular journey. This article is not individual legal advice.13
Recheck before travelling
Laws and procedures can change. Save the official source and the date you checked it. Make sure it covers your circumstances and transit stops. If information is missing or unclear, contact the relevant embassy or authority. Product quality and storage temperature are separate from import permission.12
Find a country guide
Choose a guide for official places to check and known gaps: United Kingdom, United States, Italy, Spain, France, Germany, Japan, United Arab Emirates, Australia, Canada, Thailand, Mexico.
Rules may also apply where you depart or transit. A country guide cannot confirm the status of every product or replace checking current requirements.12
