An antibiotic is a substance that is used specifically to inhibit the growth of bacteria. However, these substances are ineffective against viruses.

In bacteria, antibiotics work by targeting the internal growth mechanisms, but since the mechanism of viruses is completely different, antibiotics are deemed ineffective.
