How to take this antibiotic correctly in adults and children?

Adults and children over 10 years old

The average cephalexin dose, in this case, is 250-500 mg every 6 hours. The daily dose should be at least 1-2 g, and if necessary it can be increased to 4 g. The course of treatment lasts for 7-14 days. The minimum duration of treatment is 10 days in infections caused by beta-hemolytic group A streptococcus.

Adult patients with impaired renal function

In this case, the daily dose is reduced taking into account the QC value: with a QC of 5-20 ml/min, the maximum daily dose is 1.5 g/day; with CC less than 5 ml/min – 0.5 g/day. The daily dose is divided into 4 doses.

Children under 10 years old

The drug is recommended in the form of a suspension for oral administration. The average daily dose is 25-100 mg/kg of body weight with a body weight of less than 40 kg; frequency of admission – 4 times/day.

How long does Cephalexin stay in your system?

After oral administration, it is rapidly and well absorbed. Bioavailability is 90-95%. Food intake slows down absorption, but does not affect its completeness. The time to reach Cmax after oral administration of 0.25, 0.5 or 1 g is 1 hour, the value of Cmax is 9, 18 and 32 μg/ml, respectively. The therapeutic concentration persists for 4-6 hours. Binding with plasma proteins – 10 – 15%.


Side effects


Cephalexin enhances the effect of indirect anticoagulants. It enhances nephrotoxicity of aminoglycosides, polymyxins, phenylbutazone, furosemide. Salicylates and indomethacin slow down the excretion of the described antibiotic by the kidneys. Medications that reduce tubular secretion increase the drug concentration in the blood and slow down its excretion.

In a study of 12 healthy people who took a single dose (500 mg) of cephalexin and metformin, the values of Cmax and AUC increased, on average, by 34% and 24%, respectively, the value of renal clearance of metformin decreased by 14%. No adverse reactions were noted in this study. Information on the interaction of cephalexin and metformin after repeated administration is not available. The development of hypokalemia in patients treated with gentamicin and cephalexin at the same time has been described.

Like other beta-lactam preparations, probenecid inhibits the renal excretion of cephalexin.

Concurrent treatment with high doses of cephalosporins and nephrotoxic drugs such as aminoglycosides and strong diuretics can adversely affect kidney function.

During treatment with this drug, and also within 7 days after treatment with it, it is necessary to refuse to take oral contraceptives and use an alternative method of non-hormonal contraception.

While taking this antibiotic, a false-high concentration of creatinine is possible.

During the treatment period, ethanol is not recommended. In patients with impaired renal function, cumulation is possible (correction of the dosage regimen is required). In staph infections, there is cross-resistance between cephalosporins and isoxazolylpenicillins.

In addition, diarrheal disease is possible due to an imbalance in the intestinal flora. Follow cephalexin warnings to avoid severe side effects.
