Generic Name: Cefoxitin sodium
Product Name: Mefoxin

Indication

Cefoxitin sodium is for the treatment of the following infections when they are caused by susceptible organisms:
– infections in the abdomen and pelvis
– female genital tract infections
– blood infection
– heart valve infection
– urinary tract infections
– respiratory tract infections
– bone and joint infections
– skin and skin structure infections
Cefoxitin sodium can also be used in combination with surgical drainage in the treatment of:
– abscesses
– organ perforation complicated by infection
– cutaneous infection
– infection of serous surfaces
Post operative infections following gastrointestinal, biliary or genital surgery may be treated with Cefoxitin.
In the treatment of any infection, it is important to isolate the bacteria and its antibacterial susceptibilities if possible before commencing treatment.

Action

Cefoxitin is from the cephalosporin family of antibiotics and is a second-generation cephalosporin. It kills bacteria by inhibiting production of an important component of bacterial cell walls. It is active against a large number of aerobic (those that require oxygen) and anaerobic (those that can grow without oxygen) bacteria. Some well-known bacteria that Cefoxitin is active against include:
– Staphylococcus aureus
– Streptococcus pneumoniae
– E. coli
– Neisseria gonorrhoea, the bug responsible for gonorrhoea
– Neisseria meningitidis (meningococcus)
– the food poisoning bugs Salmonella and Shigella
– Propionibacterium acnes, the bug responsible for the skin condition acne vulgaris
Cefoxitin is not active against Pseudomonas and Enterococci, which are bugs that can cause serious in-hospital infections.

Cefoxitin sodium for injection is to be used intravenously and intramuscularly.
Adults
– usual dose is 1-2g every eight hours, with 3g every 4-6 hours being used in serious infections

Renal impairment
– loading dose of 1-2g should be given
– dosage adjustment should then be made depending on renal function
Uncomplicated gonorrhoea
