Indications

You can use Cephalexin to treat one of the following bacterial infections:

  • Respiratory tract infection (including pneumonia, bronchitis, tonsillitis, and strep throat)
  • Bone infection (osteomyelitis)
  • Sinus infection (sinusitis)
  • Ear infection (otitis media)

Cephalexin is often used for common infections in patients who have an allergy to penicillin.

Mechanism of Action

Cephalexin is a part of a group of antibiotics known as cephalosporins. It works by preventing bacteria from cell wall formation, thereby causing them to die and preventing the infection from further spreading.

Among the bacteria which Cephalexin is effective against are the following: Streptococcus pneumoniae, Streptococcus pyogenes, Staphylococcus aureus, E.coli, and Klebsiella pneumonia.

How Supplied

Cephalexin comes as a tablet, capsule, and oral suspension. Cephalexin tablets are available in two strengths: Cephalexin 250 mg and Cephalexin 500 mg.

Dosage and Administration

The following information includes general considerations for how Cephalexin should be used:

  • If Cephalexin tablets bother your stomach, take them with milk or food. They can be taken without food as well.
  • Shake the oral suspension before each use.
  • For most infections, Cephalexin tablets should be taken two or four times a day.
  • It is important to keep an even level of Cephalexin in your body, so try to take it at about the same times.
  • Although you may start feeling better after the first few days of treatment with Cephalexin, you should continue taking the drug for the full treatment course. Your infection may not be treated completely if you stop using Cephalexin pills too soon.
