ADHD Medication Shortage Grips Japan Amid Soaring Demand
Since last fall, Concerta, a vital medication for treating ADHD, has faced a nationwide shortage, impacting both new and existing patients. Despite initial assurances, Janssen Pharmaceutical now estimates it will take “more than several months” for the oral medication to be fully restocked. This ongoing scarcity is particularly worrying given the rising rates of ADHD diagnoses in Japan, especially among adults, and Concerta’s status as one of only three available adult ADHD treatments.
