Overview of Keflex

Keflex is a commonly prescribed antibiotic medication that belongs to the class of drugs known as cephalosporins. It is primarily used to treat bacterial infections in various parts of the body, including the skin, respiratory tract, and urinary tract. Keflex works by interfering with the formation of the bacterial cell wall, which ultimately leads to the destruction of the bacteria.

Common conditions treated by Keflex include:

  • Skin infections, such as cellulitis or impetigo
  • Respiratory tract infections, including bronchitis and pneumonia
  • Urinary tract infections, such as cystitis or pyelonephritis

By targeting the specific bacteria causing these infections, Keflex helps to alleviate symptoms, prevent complications, and promote recovery.

How Keflex works in the body to fight bacterial infections

When Keflex is ingested, it is absorbed into the bloodstream and distributed throughout the body. It then reaches the specific site of infection, where it exerts its antimicrobial effects. Keflex inhibits the synthesis of the bacteria’s cell wall by interfering with the enzymes responsible for its production.

Without a properly functioning cell wall, bacteria become structurally unstable and unable to grow or reproduce. This weakens their ability to survive and causes them to eventually die off. By targeting the cell wall, Keflex effectively eliminates the bacteria responsible for the infection.

It is important to note that Keflex is only effective against bacterial infections and does not have any impact on viral infections, such as the common cold or flu.

Keflex dosing and administration

Recommended dosage for different conditions

Skin infections:

The recommended dosage for treating skin infections with Keflex is 250-500 mg taken orally every 6 hours for 7-14 days. In more severe infections, higher doses may be required, up to a maximum of 4 grams per day.

Urinary tract infections (UTIs):

For uncomplicated UTIs, the usual adult dose of Keflex is 250 mg every 6 hours, or 500 mg every 12 hours, for 7-14 days. For more severe or complicated UTIs, higher doses may be necessary. In pediatric patients, the recommended dose is 25-50 mg/kg/day in divided doses.

Respiratory infections:

In the treatment of respiratory tract infections, the usual adult dose of Keflex is 250-500 mg every 6 hours for 7-14 days, depending on the severity of the infection. For pediatric patients, the recommended dose is 25-50 mg/kg/day in divided doses.

How to take Keflex

Keflex should be taken orally with or without food. It is important to follow the prescribed dosage and the specific instructions given by the healthcare provider. The duration of treatment may vary depending on the condition being treated.

If a dose is missed, it should be taken as soon as possible. However, if it is almost time for the next scheduled dose, the missed dose should be skipped and the regular dosing schedule should be followed. Double doses should not be taken to make up for a missed dose.

Precautions and important considerations

When taking Keflex, it is important to consider the following:

  • Food interactions: Keflex can be taken with or without food, as it does not significantly affect absorption.
  • Allergies: Individuals with a known allergy to cephalosporin antibiotics should not take Keflex.
  • Renal impairment: Dosage adjustments may be necessary for individuals with impaired renal function. Consultation with a healthcare professional is recommended.
  • Pregnancy and breastfeeding: Keflex is generally considered safe to use during pregnancy and while breastfeeding. However, it is important to consult with a healthcare provider for individualized advice.
  • Drug interactions: Certain medications may interact with Keflex, including medications that affect renal function and the effectiveness of birth control pills. It is advisable to discuss all current medications with a healthcare provider before starting Keflex.
