For adults:
Take a dose of 500mg 3 times a day. In case of severe infection or deep localization, especially less susceptible bacteria, it is necessary to increase the dose by 1g x 3 times a day or 1.5g x 4 times a day.

For children, the dose should be calculated based on body weight, especially for young children. Recommendations may be based on dosages of 25 to 60 mg/kg body weight/day. For children with chronic infections or serious infections, deep localized, the dose should be increased to 100 mg/kg body weight/day and used for a maximum of 4 days. Children over 12 years old: take 3 times a day, 500mg once a day. Children from 5 to 12 years old: 3 times a day, 1 time 250mg. Children from 1 to 5 years old: 3 times a day, 1 time 125mg.

Although up to now Cephalexin has not been shown to have nephrotoxicity, however, Cephalexin is eliminated mainly by the kidneys, which can cause unnecessary accumulation when renal function is reduced by more than half of normal. often. The recommended maximum dose reduction to suit these subjects is 4g daily for children and 6g for adults.

Concomitant use of high doses of Vialexin 500 with strong diuretics or Aminoglycosides may affect the kidney function of the patient.

When Cholestyramine and Cephalexin are used at the same time, they will bind together in the intestines, reducing the absorption of each other. For Cephalexin, serum concentrations and half-life were increased and renal excretion was decreased when Vialexin 500 was co-administered with Probenecid. The effect of Metformin is increased, but the effectiveness of the typhoid vaccine is decreased when co-administered with Vialexin 500. Uricinogenic agents increase the effect of Cephalexin in Vialexin 500.
