Cephalexin is an antibiotic medication used to treat a variety of bacterial infections. It is a first-generation cephalosporin, a type of antibiotic that is effective against a wide range of bacteria. Cephalexin is typically used to treat infections of the skin, urinary tract, respiratory tract, and bones and joints.
Cephalexin works by interfering with the ability of bacteria to build their cell walls. This leads to the death of the bacteria. Cephalexin is a safe and effective antibiotic that is generally well-tolerated. The most common side effects of cephalexin include diarrhea, nausea, and vomiting. Allergic reactions to cephalexin are rare.
Cephalexin is a prescription medication that is available in both capsule and liquid form. It is typically taken twice a day with or without food. The dosage of cephalexin will depend on the type of infection being treated and the patient's age and weight.

Sepsis
Sepsis is a life-threatening condition that occurs when the body's response to an infection damages its own tissues and organs. Sepsis can be caused by any type of infection, but it is most commonly caused by bacterial infections.
- Severe sepsis: This is a more severe form of sepsis that is characterized by organ dysfunction. Organ dysfunction means that an organ is not working properly.
