Cephalexin belongs to cephalosporin antibiotic of the first generation. It acquires bactericidal properties. It disrupts the synthesis of microorganisms’ cell wall. It is resistant to lactamases.
This antibiotic has a wide range of effects. It is active against:
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.
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.
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.
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%.
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.
There is an list of drugs that have a detrimental effect on infections. They are also assigned to expectant mothers because they cannot harm the fetus.
One of the side effects of this antibacterial agents’ nature is the development of a possible allergy.
In order to avoid such consequences as dysbiosis, it is better to use a complex of vitamins prescribed by a gynecologist along with antibiotics. Their incorrect intake can also negatively affect the health of the expectant mother and fetus.
Watch the video why it is dangerous to take antibiotics during pregnancy:
This antibiotic of the first generation is prescribed for oral administration. Like most antibiotics from the group of cephalosporins, excretion occurs in breast milk in very small amounts and is clinically insignificant.
Cephalosporins are widely used in pediatric practice with good tolerance, even in the neonatal period, so it is unlikely to bring damage to baby health.
Keep in mind there is the possibility of false negative results of cultures in febrile children whose mothers take antibiotics, as well as the possibility of gastroenteritis, changing the intestinal flora.
Patients with a history of allergic reactions to penicillins and carbapenems may have an increased sensitivity to cephalosporin antibiotics.
During treatment with this antibiotic, a positive direct Coombs test is possible, as well as a false positive urine reaction to glucose.
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.
It is used to treat dogs with diseases of the respiratory tract, the gastrointestinal tract, the genitourinary system and skin, localized infections of soft tissues, osteomyelitis caused by microorganisms sensitive to this substance.
The dosage is individual. The duration of therapy is for 5 or more days at a dose of 10-15 mg of cephalexin per 1 kg of animal weight 2 times a day (in severe cases, the dose can be doubled).
|Small dogs (less than 15 kg of live weight)||0, 5 tablets 2 times a day|
|Medium-sized dogs (16 – 34 kg of live weight)||0.5 – 1 tablet twice a day|
|Big dogs (35 – 50 kg of live weight)||1 tablet twice a day|
In rare cases, nausea and vomiting may occur. The drug should be discontinued with the appearance of these symptoms.
