Cephalexin, a widely used antibiotic, is often prescribed to adults for the treatment of various bacterial infections. The standard dosage of cephalexin for adults is 250mg or 500mg, taken orally every 6-8 hours for 7-14 days, depending on the severity and type of infection.

Cephalexin 500mg Dosage for Adults: Indications and Effectiveness
Cephalexin 500mg is commonly prescribed for adults to treat bacterial infections such as respiratory tract infections, skin infections, urinary tract infections, and bone infections. The medication works by interfering with the bacterial cell wall synthesis, ultimately leading to the death of the bacteria. Studies have shown that cephalexin is effective against a wide range of bacteria, including Staphylococcus aureus, Streptococcus pneumoniae, and Escherichia coli.
Proper Dosage and Administration
