General information
Cefoxitin is a cephalosporin antibiotic.

Cephalosporin antibiotics are a class of antibiotics with a broad spectrum of action. It is similar to penicillin in both its chemical structure and mode of action.

Due to the similarity between cephalosporins and penicillin, cross-sensitivity is possible and a small percentage of those allergic to penicillin may also develop an allergic reaction to cephalosporins.

Cefoxitin is a broad-spectrum antibiotic effective in treating a variety of bacterial infections including infections of the respiratory, urinary and gastro-intestinal tract, as well as certain skin, soft tissue, bone and joint infections. Cefoxitin is also used in treating gonorrhoea, septicaemia, an invasion of the bloodstream by micro-organisms, and endocarditis, an infection of the membrane lining the heart. Cefoxitin is generally used to treat severe infections, or before an operation to prevent infection after surgery.

It is important to note that this medication is only effective against bacterial infections - if your infection is the result of a viral or fungal infection, it will be ineffective.

Antibiotic resistance occurs when a bacterium develops the ability to defend itself against the effect of an antibiotic. It may also occur with cephalosporins. The most common causes for resistance are patients not completing prescribed antibiotic courses allowing the bacteria to recover from treatment, and the use of antibiotics for non-bacterial infections, such as cold and flu.

How does Cefoxitin work?
Cefoxitin weakens the bacterial cell wall and allows water to enter the cell, causing cells to burst.
