Frequently asked questions (FAQ)
Can I get Concerta refilled while staying in Japan?
Only from a psychiatrist registered in the ADHD drug program, usually after an assessment with your medical records. It is not a same-day refill, so bring enough for your stay (up to the 1-month limit) or apply for advance approval for more.
