A member asked:
Please tell me how long it takes for penicillin to take effect?
A doctor has provided 1 answer
Question unclear: If you mean how long to begin to have improvement of symptoms it may take some time because they are often the result of the body's reaction to the organism. Also depends upon what the pcn is treating. If strep throat, never. Pcn begins to inhibit the growth of bacteria and then the wbcs help finish the job. This is complex.
