Antibiotic

抗生物質 (Kōsei busshitsu)

A class of medication used to treat bacterial infections by killing or inhibiting the growth of bacteria. Antibiotics are not effective against viruses, so they are not prescribed for common colds or influenza. In Japan, antibiotics require a doctor's prescription and are dispensed at a pharmacy. Completing the full prescribed course is essential to prevent antibiotic-resistant bacteria from developing.

Japan has historically over-prescribed antibiotics for respiratory illnesses, but updated guidelines now discourage routine antibiotic use for viral conditions like colds.
