Cefixime: Uses, Dosage, Side Effects and More

Introduction: What is Cefixime?

If you've been prescribed Cefixime, you're taking a broad-spectrum antibiotic from the cephalosporin class, commonly used to treat a variety of bacterial infections. It works by inhibiting the growth of bacteria, making it a versatile option for conditions such as respiratory tract infections, urinary tract infections, and certain types of gastroenteritis. Cefixime is effective against a range of gram-positive and gram-negative bacteria. It is available in oral forms, typically as tablets or suspension. This guide provides a comprehensive overview of cefixime, covering its uses, dosage, side effects, drug interactions, and benefits.

Uses of Cefixime

Cefixime is approved for several medical uses, including:

1. Respiratory Tract Infections: It is commonly used to treat infections such as pneumonia, bronchitis, and sinusitis.
2. Urinary Tract Infections (UTIs): Cefixime is effective against bacteria that cause UTIs, including cystitis and pyelonephritis.
3. Gonorrhea: It is used to treat uncomplicated gonococcal infections.
4. Otitis Media: Cefixime can be prescribed for middle ear infections, especially in children.
5. Pharyngitis and Tonsillitis: It is also indicated for treating throat infections caused by bacteria.

How It Works

Cefixime works by disrupting the synthesis of the bacterial cell wall. In simpler terms, it interferes with the bacteria's ability to build and maintain their protective outer layer. Without a strong cell wall, bacteria cannot survive or multiply, leading to their eventual death. This mechanism makes cefixime effective against a wide variety of bacterial infections.

Dosage and Administration

The dosage of cefixime varies based on the type of infection and the patient's age.

• Adults: The standard dosage is usually 400 mg per day, taken as a single dose or divided into two doses.
• Children: For pediatric patients, the dosage is typically based on body weight, often around 8 mg/kg per day, not exceeding 400 mg.

Cefixime is available in tablet form and as an oral suspension. It is important to take cefixime with or without food as directed by a healthcare provider, and to complete the full course of treatment even if symptoms improve.

Side Effects of Cefixime

Like all medications, cefixime can cause side effects. Common side effects include:

• Diarrhea

• Headache

Serious side effects, though less common, may include:

• Severe gastrointestinal issues (such as colitis)
• Liver problems (indicated by jaundice)
• Blood disorders (such as low platelet count)

Patients should seek medical attention if they experience any severe or unusual symptoms.

Drug Interactions

Cefixime may interact with other medications, which can affect its efficacy or increase the risk of side effects. Major drug interactions include:

• Anticoagulants: Such as warfarin, which may increase bleeding risk.
• Probenecid: This medication can increase cefixime levels in the blood, potentially leading to toxicity.
• Other Antibiotics: Using multiple antibiotics can lead to reduced effectiveness or increased side effects.

Always inform your healthcare provider about all medications and supplements you are taking to avoid potential interactions.
