Penicillin normally takes a few hours to about 5 days to take effect; however, it doesn't relieve pain. Penicillin is a combination of antibiotics that only protects the body from bacterial infection or treats the body against current infection. Penicillin normally inhibits the new bacteria, but it does not work when bacteria replicates.
Penicillin is mostly used to treat bacterial infection in the urinary track, chest and skin, as stated by NHS. Penicillin exists in various types, such as ampicillin, amoxicillin, flucloxacillin and phenoxymethylpenicillin, that react in different degrees. The human body has an immune system that attacks harmful bacteria before they replicate. The white blood cells are enough to fight the bacterial infection on their own, though sometimes antibiotics are taken to supplement the immune response.
Penicillin is taken to help the body in fighting bacterial infections, to block infection in cases of low body immunity and to supplement the human immunity in situations where an individual maybe exposed to bacterial infection. Bacteria protects itself through continuous rebuilding of its cell walls, but is killed by penicillin through damaging and penetrating the bacteria cell walls. Continuous use of penicillin may lead to adverse effects, such as diarrhea, feeling sick, rashes and allergic reactions.
