Introduction

What are the uses of this drug and why it is prescribed by doctors? This is the question many patients have when doctors prescribe them with Keflex. Keflex, or cephalexin, is a drug used to treat a myriad of different bacterial infections as it is one of the well-known antibiotics in the market. It is most useful in treating pneumonia, boils, or any skin related infections. In this article we will focus on the general working action of the drug and its mechanisms.

What is Keflex?

Keflex, or cephalexin, is defined as an antibiotic that is generally targeted towards gram-positive infections. Moreover, it is effective in treating skin, bone or pneumonia infections as well. And is a member of the psuedomonic acid group. Unlike other forms of antibiotics, Keflex works in a slightly different way by stopping the staphylococcus bacteria from multiplying in number.

Keflex (cephalexin) is an oral antibiotic that belongs to a class of drugs called cephalosporins. It works by kiling the bacteria or preventing them from growing. All viruses like the flu also the cold, are not bacterial infections so this drug cannot be useful for them.

Consider it a specialist in destroying bacteria that focuses in certain parts of your body.
