Cephalexin 500mg Capsules are a prescription oral antibiotic medication used to treat a wide range of bacterial infections. Cephalexin belongs to the cephalosporin class of antibiotics, which work by stopping the growth and multiplication of bacteria. Each capsule contains 500 mg of the active ingredient cephalexin, making it an effective, doctor-recommended choice for fighting infections in both adults and children.
Uses and Indications
Cephalexin 500mg Capsules are used to treat infections caused by susceptible bacteria, including:
-
Respiratory Tract Infections: Such as bronchitis, tonsillitis, throat infections (pharyngitis), and sinusitis.
-
Ear Infections (Otitis Media): Bacterial ear infections.
-
Skin and Soft Tissue Infections: Including cellulitis, wound infections, and impetigo.
-
Bone Infections (Osteomyelitis): Treatment of bacterial bone infections.
-
Genitourinary Tract Infections: Such as urinary tract infections (UTIs, cystitis) and kidney infections (pyelonephritis).
-
Dental Infections: Prescribed for some dental abscesses or gum infections.
How Does Cephalexin Work?
Cephalexin fights bacteria by targeting their cell walls, causing the walls to break down and the bacteria to die. It is not effective against viral infections such as colds or the flu.
Dosage and Administration
-
Standard Adult Dose: 250 mg to 1000 mg every 6 to 12 hours, as prescribed by your doctor. For most infections, 500 mg every 12 hours is typical.
-
Children: Dosing is based on weight and infection severity—your doctor will provide appropriate instructions.
-
Directions: Take capsules with or without food. Swallow whole with a glass of water. Complete the full course, even if you feel better, to prevent antibiotic resistance.
