"when the major attack occurs, penicillin won't work"

Is that true? People routinely take the same antibiotic at different times in their lives without loss of effectiveness. There is a danger of reduced effectiveness if an antibiotic is overused, and over time new strains of a bacteria might appear which are resistant to the antibiotic, but I never heard there was significant danger of an antibiotic becoming ineffective after a single use.

I don't know, am asking that too.
