What is Keflex?

Keflex, also known as cephalexin, is an antibiotic belonging to the cephalosporin class. It’s used to fight bacteria in the body and is particularly effective due to its ability to disrupt the bacteria’s cell wall synthesis, leading to cell death. Originally derived from fungi, cephalosporins have evolved to include a broad range of antibiotics, making Keflex one of the most prescribed antibiotics for bacterial infections.

How Does Keflex Work?

Mechanism of Action

Keflex works by interfering with the formation of the bacteria’s cell wall, causing it to rupture and the bacteria to die. This makes it effective in reducing the bacterial proliferation in the infected area.

Spectrum of Efficacy

Keflex is effective against a wide range of bacteria. It primarily targets gram-positive bacteria, including Streptococcus and Staphylococcus species, and also some gram-negative bacteria like E. coli. This makes it versatile in treating various infections.

Common Uses of Keflex

Keflex is commonly prescribed for several types of infections:

• Respiratory Tract Infections: Such as bronchitis and pharyngitis.
• Ear Infections: Including otitis media.
• Skin Infections: Like cellulitis and impetigo.
• Urinary Tract Infections (UTIs): Effective against UTIs when caused by susceptible bacteria.

Dosage and Administration

Proper dosage is crucial for the effectiveness of Keflex. Typically, the dosage varies based on the type and severity of the infection, patient age, and kidney function. Most adult dosages range from 250 mg to 1 gram every 6 to 12 hours. It’s imperative to complete the full prescribed course even if symptoms improve early to prevent resistance.

Possible Side Effects

While generally well-tolerated, Keflex can cause side effects:

• Gastrointestinal issues like diarrhea, nausea, and vomiting.
• Possible allergic reactions, including rash or anaphylaxis in severe cases.
• Superinfections due to prolonged use, although rare.

Patients should be informed of potential reactions and advised to seek medical attention if side effects are severe.
