Cefuroxime is a semi-synthetic β-lactam antibiotic belonging to the second-generation cephalosporins. It is primarily used to treat a variety of infections caused by susceptible bacteria, such as otitis media, sinusitis, pharyngitis, pneumonia, urinary tract infections, and skin infections. Its mechanism involves inhibiting bacterial cell wall synthesis, leading to bacterial death. It has broad-spectrum activity against both Gram-positive and some Gram-negative bacteria.
The scientific name of cefuroxime is cefuroxime. Common brand names include Zinacef, Zinnat, among others. Different countries or regions may have different commercial names, so use should be based on a healthcare professional’s prescription.
This medication is classified as a second-generation cephalosporin within the β-lactam antibiotic group. It has broad-spectrum antibacterial properties and is suitable for treating moderate to severe bacterial infections. Its structural characteristics give it stronger activity against certain Enterobacteriaceae compared to first-generation cephalosporins.
Cefuroxime is approved for treating various bacterial infections, including otitis media, sinusitis, community-acquired pneumonia, urinary tract infections, and skin and soft tissue infections. In specific cases, it can also be used prophylactically in surgical procedures to reduce postoperative infection risk.
Minor side effects may include gastrointestinal discomfort such as diarrhea, nausea, or abdominal pain, which usually resolve within a few days after stopping the medication. Some patients may experience headaches or skin itching. If symptoms persist, consult a healthcare provider.
Individuals allergic to penicillin or cephalosporins should avoid use. Prior to use, detailed allergy history should be provided to the healthcare provider. Patients with hepatic or renal impairment may require dose adjustments to prevent drug accumulation and toxicity.
Concurrent use with antacids (such as aluminum or magnesium preparations) may reduce absorption; it is recommended to take at least 2 hours apart. Combining with anticoagulants (such as warfarin) may increase bleeding risk; regular coagulation monitoring is advised.
Oral formulations are usually taken twice daily, preferably with meals to enhance absorption. Injectable forms should be administered by healthcare professionals, with doses calculated based on infection severity and patient weight. Do not adjust doses or discontinue medication without medical advice. Complete the full course to prevent resistance development.
If a dose is missed and more than 4 hours remain before the next scheduled dose, take it as soon as remembered. If the timing is close to the next dose, skip the missed dose and resume the regular schedule. Do not double doses to make up for missed ones, as this may increase side effects.
Oral overdose may cause severe diarrhea or gastrointestinal discomfort; seek medical attention immediately. If signs of allergic reactions such as difficulty breathing or altered consciousness occur, seek emergency care and inform healthcare providers of the medication name and dosage taken.
Cefuroxime can be taken with or without food. However, if gastrointestinal symptoms such as stomach pain or nausea occur, taking it with food may help alleviate these symptoms. Absorption is not significantly affected by food intake, so patients can adjust timing based on personal tolerance.
If skin itching or rash occurs during cefuroxime use, what should be done?If skin redness, itching, or hives develop, it may be an early sign of an allergic reaction. Discontinue the medication immediately and contact a healthcare provider. Avoid continuing the medication on your own. Severe reactions may include difficulty breathing, requiring emergency care. Mild itching can be monitored but should not be ignored.
Is cefuroxime safe for use during pregnancy or breastfeeding?Cefuroxime is classified as a Category B drug during pregnancy, indicating relative safety for short-term use under medical supervision. During breastfeeding, the drug can pass into breast milk in low amounts with rare adverse effects on the infant. However, breastfeeding should be discussed with a healthcare provider, especially if the mother has breast cancer or if the infant is sensitive to medications.
What interactions should be considered when combining cefuroxime with other antibiotics or analgesics?Concurrent use with antacids (such as aluminum or magnesium preparations) within 2 hours may reduce absorption. Combining with diuretics (such as furosemide) requires kidney function monitoring to prevent increased nephrotoxicity. Alcohol should be avoided as it may induce disulfiram-like reactions (such as dizziness, nausea).
If mild diarrhea occurs during medication, should the drug be stopped immediately?Mild diarrhea may be due to disruption of intestinal flora and can be managed with hydration and electrolytes. If diarrhea persists beyond 48 hours or is accompanied by blood in stool or severe abdominal pain, discontinue the medication and seek medical attention. Further evaluation may be needed to rule out Clostridium difficile infection or other severe intolerance reactions.
