Appointment during pregnancy and lactation

Cefazolin crosses the placenta and affects the fetus, so the antibiotic during pregnancy can only be used if there is absolute evidence when there is a threat to the life of the mother. To date, it has not been clarified exactly what effect Cefazolin has on the fetus, therefore, when deciding on the use of antibiotics by pregnant women, it is necessary to carefully weigh the possible risk / intended benefit ratio.
To date, Cefazolin tests have been conducted only on pregnant rats. Moreover, the drug in large doses did not cause teratogenic effects, that is, did not lead to the formation of congenital malformations of the fetus. However, similar controlled studies on pregnant women for obvious reasons have not been conducted.
Cefazolin also penetrates into breast milk, although there it is detected in small concentrations. However, if necessary, its use during lactation should transfer the child to the artificial mixture at the time of treatment.

Dosage and method of use

For the prevention of postoperative infection - in / in 1 g for 0.5-1 h before surgery, 0.5-1 g - during surgery and 0.5-1 g - every 8 hours during the first days after surgery.
Patients with impaired renal function require a change in the dosage regimen in accordance with the CC values: with a CC of 55 ml / min or more or with a creatinine concentration in the plasma of 1.5 mg% or less, the full dose can be administered; with CC 54-35 ml / min or plasma creatinine concentration of 1.6-3.0 mg%, the full dose can be administered, but the intervals between injections should be increased to 8 hours; at CC 34–11 ml / min or plasma creatinine concentration 3.1–4.5 mg% - 1/2 dose at 12 h intervals; if QC is 10 ml / min or less, or when plasma creatinine concentration is 4.6 mg% or more, 1/2 of the usual dose every 18-24 hours. All recommended doses are administered after the initial loading dose of 500 mg.
Children 1 month and older - 25-50 mg / kg / day; in case of severe infection, the dose may be increased to 100 mg / kg / day. The frequency of administration is 3-4 times / day.
In children with impaired renal function, dosing regimen adjustment is carried out depending on the CC values: with CC 40–70 ml / min - 60% of the average daily dose and administered every 12 hours; with CC 20-40 ml / min - 25% of the average daily dose with an interval of 12 hours; if QC is 5-20 ml / min - 10% of the average daily dose every 24 hours.

For iv administration, the drug is diluted with 50-100 ml of 5% or 10% dextrose solution, 0.9% sodium chloride solution, Ringer's solution, 5% sodium bicarbonate solution.

How much prick Cefazolin?

The duration of Cefazolin use depends on the severity of the infection and the speed of recovery. The course of treatment lasts from 7 to 14 days. Do not use Cefazolin injections for less than 5 days or more than 15 days, because in this case there is a high risk of developing antibiotic-resistant types of microorganisms. These resistant microorganisms are able to cause an infection again, which will have to be treated again, only with the use of another, even stronger antibiotic. Unfortunately, there is a great risk that, to another antibiotic, the microorganism may be resistant. In this case, the prognosis for life is unfavorable, since there are very few antibiotics in the world that can cope with resistant microbes. And if they do not help, then you can only rely on the immunity of the sick.
That is why the use of antibiotics, including Cefazolin, must be treated responsibly. You can not throw injections as soon as the person becomes better, considering the treatment is over. A minimum of 5 days of Cefazolin injections should be made, overcoming pain and reluctance. This is especially true of children. After all, a child is faster and easier than an adult can “acquire” resistant types of microbes that will constantly cause infections that are difficult to treat.

Adverse reactions

The use of antibiotics, especially long-term can cause adverse reactions from various body systems:
    pruritus;
    rash in the form of urticaria;
    a sharp drop in platelet levels in the blood;
    leukemia symptoms;
    the occurrence of hemolytic anemia;
    ulcers in the mouth and lips;
    rapidly progressive stomatitis;
    manifestations of pancreatitis in acute form;
    vomiting and nausea;
    diarrhea;
    liver dysfunction;
    development of bronchospasm;
    pronounced swelling of the respiratory tract;
    appearance of skin toxic necrolysis;
    development of symptoms of granulocytopenia;
    the appearance of signs similar to interstitial nephritis;
    hair loss and severe itching in the genital area.
In addition, during the injection itself may begin sweating, accompanied by chills and a transition to muscle cramps, an attack of tachycardia, difficulty breathing, until it stops. If at least one of these symptoms occurs, drug administration immediately stops, the medication is replaced with another medication with the same therapeutic effect. In addition, intramuscular administration of the antibiotic can be painful and tissue consolidation often occurs in the area of ​​the injection.

Symptoms of overdose

Overdose after misuse of the antibiotic Cefazolin is permissible and it manifests itself with a number of symptoms, such as:
    Paresthesia;
    Sudden heart rhythm disturbances;
    Involuntary muscle contractions;
    Convulsive syndrome;
    Headaches;
    Dizziness;
    Vomiting.
The treatment of these symptoms is as follows: first, you need to immediately stop putting injections with the drug, and secondly, if the symptoms bother the patient too much, he needs to start taking medicines that can eliminate them. It is noticed that the body itself contributes to the withdrawal of the antibiotic - with an overdose, hemodialysis is accelerated, which contributes to the early completion of the whole process. Well, if the case is very difficult, then hospitalization occurs and mechanical blood cleaning is used - dialysis.

Patient Reviews

We offer you to read the reviews of people who used Cefazolin:
    Tosh

Good cheap drug. I was stabbed at the hospital for pneumonia. Very painful injections, therefore, for dilution, use not water, but Lidocaine or Novocain will be really easier. Pneumonia on this treatment was also quick, although it was frightening atypical, but it turned out to be the most typical, and besides, the little one could not resist the antibiotic Cefazolin.
    Alexandra

Good drug! Not to say that it hurts a lot, but I always do it with Novocaine. Treated them and exacerbation of pyelonephritis 2 times and orvi. Also, when having an rsi in a jar, after taking the medicine, I poured 1 ml of boiled water and dripped into my nose, since the nose was stuffed so that it began to lay my ears. Also, when the filling fell out, and under it there was a terrible inflammation that half the face was already swollen, took Cefazolin, and slightly moistened the ear stick with her saliva, collected powder and put it into the hole and stayed quiet the night before going to the dentist. (This is all the advice of my grandmother-doctor of the Soviet school).
    Marina

I was prescribed cefazolin injections for a complicated sore throat. Already after the first injection, the state of health worsened, it became shivering, threw it into heat, then into cold. Subsequent injections led to severe dizziness, headaches, and then rashes and severe itching that caused the whole body to itch. In addition, the injections were very painful, it turns out they needed to be diluted with lidocaine or novocaine, and I was injected with a usual solution in water for injection. The doctor said that this is definitely an allergic reaction, so the drug had to be replaced with another antibiotic. So, much depends on the professionalism of physicians.
