Cefuroxime axetil

Common Uses

Cefuroxime axetil is prescribed to treat a wide range of infections caused by susceptible bacteria. It is commonly used for the following conditions:

• Respiratory Tract Infections: This includes pharyngitis (sore throat), tonsillitis, acute bacterial sinusitis, and bacterial flare-ups of chronic bronchitis.
• Ear Infections: It is used to treat middle ear infections, also known as acute otitis media.
• Skin Infections: It treats uncomplicated infections of the skin and skin structures.
• Urinary Tract Infections: It is effective against certain uncomplicated bladder and urinary tract infections.
• Lyme Disease: It is used to treat early-stage Lyme disease (erythema migrans) in adults and children.
• Gonorrhea: It may be used to treat uncomplicated gonorrhea of the urethra or cervix.

Important Considerations

This medication only treats bacterial infections. It will not work for viral infections, such as the common cold, flu, or most coughs. Using antibiotics when they are not needed increases the risk of developing an infection later that resists antibiotic treatment.

Mechanism of Action

Cefuroxime axetil belongs to a class of medications known as cephalosporin antibiotics. It works by interfering with the way bacteria construct their cell walls. These walls are essential for the bacteria to maintain their shape and protect themselves from the surrounding environment.

When a person takes cefuroxime axetil, the medication binds to specific proteins within the bacterial cell. This action blocks the bacteria from completing the final steps of building their cell walls. Without a strong, intact wall, the internal pressure of the bacterial cell causes it to burst and die.

Targeting Bacteria

Because this medication specifically targets the processes used by bacteria to build cell walls, it is effective against various types of bacterial infections. However, it is important to note the following:

• Bactericidal action: Cefuroxime is considered bactericidal, meaning it actively kills the bacteria rather than just stopping their growth.
• Bacterial specificity: This drug only works against bacterial infections. It does not work for viral infections, such as the common cold or the flu.
• Resistance: Using antibiotics when they are not needed can lead to antibiotic resistance, making future infections harder to treat.

Common Side Effects

Many people taking cefuroxime axetil experience mild side effects. These may include:

• Diarrhea
• Nausea or vomiting
• Stomach pain
• Dizziness or drowsiness
• Vaginal itching or discharge
• Diaper rash in infants and children

Serious Side Effects

Contact a healthcare provider immediately if you experience any of the following serious symptoms:

• Signs of an allergic reaction, such as hives, skin rash, itching, or swelling of the face, lips, tongue, or throat
• Difficulty breathing or swallowing
• Severe stomach cramps or watery or bloody diarrhea, which may occur during treatment or several months after stopping the medication
• Yellowing of the skin or the whites of the eyes
• Dark-colored urine
• Unusual bruising or bleeding
• Seizures
• Extreme tiredness or weakness

Rare but severe skin reactions can also occur. Seek emergency medical help for a fever, sore throat, burning eyes, or a red or purple skin rash that spreads and causes blistering and peeling.

Allergic Reactions

Serious and occasionally fatal hypersensitivity reactions, including anaphylaxis, have occurred. People with a history of allergy to penicillin or other beta-lactam antibiotics should use this medication with caution, as cross-sensitivity can occur. If an allergic reaction occurs, the medication must be discontinued immediately.

Diarrhea and Colitis

Treatment with antibacterial agents can change the normal flora of the colon, leading to the overgrowth of Clostridioides difficile. This can cause Clostridioides difficile-associated diarrhea (CDAD), which ranges in severity from mild diarrhea to life-threatening inflammation of the colon. This may occur during treatment or several months after the medication is stopped.

Seizure Risk

Several cephalosporins have been associated with triggering seizures, particularly in individuals with kidney impairment when the dosage was not appropriately reduced based on their kidney function. If seizures occur, the drug should be discontinued.

Lyme Disease Treatment

The Jarisch-Herxheimer reaction has been reported following the start of treatment for Lyme disease with cefuroxime axetil. Symptoms may include fever, chills, muscle pain, and headache. This is a common consequence of the antibiotic's effect on the bacteria that cause Lyme disease and usually resolves on its own.

Phenylketonuria (PKU)

The oral suspension form of this medication may contain phenylalanine (aspartame). Individuals with phenylketonuria should check the specific product labeling before use to ensure it is safe for their dietary requirements.

Laboratory Test Interference

Cefuroxime axetil may interfere with certain medical tests, potentially leading to inaccurate results. These include:

• False-positive results in urine glucose tests using copper reduction methods (such as Benedict's or Fehling's solution).
• False-negative results in blood glucose tests using ferricyanide methods.
• A positive direct Coombs' test, which can affect blood cross-matching procedures.

Drug Resistance

Using cefuroxime axetil in the absence of a proven or strongly suspected bacterial infection is unlikely to provide benefit and increases the risk of developing drug-resistant bacteria.

Pregnancy

Animal reproduction studies have not demonstrated a risk to the fetus; however, there are no adequate and well-controlled studies in pregnant women. Because animal studies do not always predict human response, cefuroxime axetil should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

If you are pregnant or planning to become pregnant, discuss the necessity of this treatment with your healthcare provider to determine the best course of action.

Breastfeeding

Cefuroxime is excreted in human breast milk. When a nursing mother takes this medication, the infant may be exposed to small amounts of the drug. While generally considered compatible with breastfeeding, potential effects on the nursing infant may include:

• Disruption of the natural bacteria in the digestive tract, which may cause diarrhea.
• Fungal infections, such as oral thrush or diaper rash.
• The possibility of an allergic reaction or sensitization to the medication.

It is important to consult with a healthcare professional to weigh the benefits of breastfeeding against any potential risks to the infant while taking this medication. They may recommend monitoring the infant for any changes in bowel habits or signs of an allergic reaction.

Oral Formulations

Cefuroxime axetil is provided in forms intended for oral administration. These include:

• Tablets: These are film-coated tablets designed to be swallowed.
• Powder for Oral Suspension: This is a powder that is mixed with water by a pharmacist to create a liquid medication.

The tablets and the oral suspension are not interchangeable. Patients should use only the specific formulation prescribed by their healthcare provider, as the way the body absorbs the medication can differ between the tablet and liquid forms.

FDA Approval Status

Cefuroxime axetil is approved by the U.S. Food and Drug Administration (FDA) as a second-generation cephalosporin antibiotic. It is available in various oral forms, including tablets and oral suspensions, for the treatment of specific infections caused by susceptible bacteria.

Approved Indications

The FDA has approved cefuroxime axetil for the treatment of several conditions, including:

• Pharyngitis and tonsillitis
• Acute bacterial otitis media (ear infections)
• Acute bacterial maxillary sinusitis
• Acute bacterial exacerbations of chronic bronchitis and secondary bacterial infections of acute bronchitis
• Uncomplicated skin and skin-structure infections
• Uncomplicated urinary tract infections
• Uncomplicated gonorrhea
• Early Lyme disease (erythema migrans)

Safety and Regulatory Oversight

There are currently no boxed warnings or Risk Evaluation and Mitigation Strategies (REMS) required for cefuroxime axetil. However, the FDA requires labeling to include warnings regarding potential hypersensitivity reactions, particularly in patients with a history of penicillin allergy, and the risk of Clostridioides difficile-associated diarrhea, which is a risk with nearly all antibacterial agents.

Generic Availability

Cefuroxime axetil is available as a generic medication. Generic drugs are typically less expensive than brand-name versions while providing the same therapeutic effect. Choosing the generic form is a common way to reduce the cost of treatment.

Factors Influencing Cost

Several factors can influence the final price of a cefuroxime axetil prescription:

• Dosage Form: The cost may vary between the oral tablets and the liquid suspension.
• Treatment Duration: The total price is affected by the number of days the medication is prescribed to treat a specific infection.
• Pharmacy Pricing: Prices can vary between different retail pharmacies, mail-order pharmacies, and geographic locations.

Insurance and Coverage

Most health insurance plans, including Medicare Part D and Medicaid, cover the generic version of cefuroxime axetil. The actual out-of-pocket cost for a patient will depend on their specific insurance plan's formulary, copayments, and deductibles. For individuals without insurance, pharmacy discount cards or coupons may be available to help lower the retail price.
