Ancef's generic name is cefazolin [1].
What is Cefazolin used for?
Cefazolin is an antibiotic that belongs to the cephalosporin class. It is used to treat a variety of bacterial infections, including those affecting the skin, bones, blood, urinary tract, and heart valves [2]. It is also frequently administered before certain surgical procedures to prevent infection [2].
How does Cefazolin work?
Cefazolin works by killing bacteria. It interferes with the formation of the bacterial cell wall, leading to the death of the bacteria [3].
When was Cefazolin first approved?
Cefazolin was first approved by the U.S. Food and Drug Administration (FDA) in December 1978 [1].
Are there different forms of Cefazolin?
Cefazolin is available as a powder that is reconstituted into a solution for injection [4]. It can be administered intravenously or intramuscularly [4].
What are the potential side effects of Cefazolin?
Common side effects of cefazolin can include diarrhea, nausea, vomiting, and pain or inflammation at the injection site [5]. More serious side effects, though less common, can include allergic reactions, kidney problems, and changes in blood cell counts [5].
What bacterial infections does Cefazolin treat?
Cefazolin is effective against a range of gram-positive and some gram-negative bacteria. It is commonly used for infections caused by Staphylococcus and Streptococcus species [2]. It is a common choice for surgical prophylaxis due to its efficacy against skin flora bacteria like Staphylococcus aureus [2].
Who manufactures Cefazolin?
Cefazolin is manufactured by several pharmaceutical companies, including Fresenius Kabi USA, Inc., Aurobindo Pharma USA, Inc., and Amneal Pharmaceuticals LLC, among others [1].
What is the typical dosage of Cefazolin?
Dosage varies depending on the type and severity of the infection, as well as the patient's kidney function [6]. Cefazolin is typically administered every 6 to 12 hours [6].
Can Cefazolin be used in children?
Yes, cefazolin can be used in children to treat bacterial infections, with dosages adjusted based on the child's weight [7].
What is the difference between Cefazolin and other cephalosporins?
Cefazolin is a first-generation cephalosporin, which generally means it has broader activity against gram-positive bacteria and more limited activity against gram-negative bacteria compared to later generations [8]. Other cephalosporins have varying spectrums of activity and are used for different types of infections [8].
What are the risks of taking Cefazolin?
The primary risks associated with cefazolin are allergic reactions, which can range from mild rashes to severe anaphylaxis [5]. Individuals with a known allergy to cephalosporins or penicillins may be at higher risk [5]. There is also a risk of developing Clostridioides difficile-associated diarrhea [5].
Can Cefazolin be used if I am pregnant or breastfeeding?
Cefazolin may be used during pregnancy if clearly needed, as its risks to the fetus are not well-established but generally considered low [9]. It is also excreted in breast milk in small amounts, so caution may be advised for breastfeeding mothers [9]. It is important to discuss these risks with a healthcare provider [9].
