Penicillin, also known as benzétacil, is an antibiotic that can be given by injection and, in some cases, can be taken orally. Oral benzetacil is best for low severity infections and should be taken every 6 hours outside meals.
It should never be indicated in the most severe cases, since once taken the pill will pass throughout the digestive tract and will undergo some modifications, decreasing its effect, in this case it is preferable the injection that takes the drug directly into the bloodstream.
