Translation guide
The English word "analgesic" refers to a substance that relieves pain. In Japanese, the most common and natural way to express this is with the word 鎮痛剤 (chintsūzai), which specifically means a pain-relieving medicine. For everyday conversation, 痛み止め (itamidome) is more casual and widely understood. This guide covers how to talk about analgesics in medical, everyday, and commercial contexts.
