What is amoxicillin Clav 875/125 mg used for?

3 min read

Did you know amoxicillin-clavulanate is one of the most frequently prescribed antimicrobial combinations in primary care worldwide? The 875/125 mg formulation, commonly known by the brand name Augmentin, is used to treat a wide array of bacterial infections, extending the antibiotic's effectiveness against resistant bacteria.

Quick Summary

This combination antibiotic, comprising amoxicillin and clavulanic acid, is prescribed for various bacterial infections, including those of the ears, sinuses, lungs, skin, and urinary tract. Its dual-action formula overcomes bacterial resistance, providing a more robust treatment option for certain illnesses.

Key Points

  • Dual-Action Antibiotic: Combines amoxicillin, a penicillin-type antibiotic, with clavulanic acid, a beta-lactamase inhibitor.

  • Broad-Spectrum Efficacy: Treats a wide range of bacterial infections, including those of the respiratory tract, sinuses, ears, skin, and urinary tract.

  • Fights Resistant Bacteria: The clavulanic acid component overcomes bacterial resistance, making it effective where amoxicillin alone might fail.

  • Common Prescriptions: Frequently prescribed for conditions like acute bacterial sinusitis and community-acquired pneumonia.

  • Take as Directed: Must be taken exactly as prescribed and the full course completed to prevent antibiotic resistance.

  • Increased GI Side Effects: Associated with a higher risk of gastrointestinal side effects, including diarrhea, compared to amoxicillin alone.

  • Not for Viral Infections: This medication is ineffective against viruses such as the common cold or flu and should only be used for bacterial infections.

Understanding the components of amoxicillin clav 875/125 mg

Amoxicillin clavulanate is a combination antibiotic containing 875 mg of amoxicillin and 125 mg of clavulanic acid. This combination is crucial for combating antibiotic resistance.

  • Amoxicillin: This penicillin-type antibiotic kills bacteria by disrupting their cell wall synthesis. It is effective against various bacteria.
  • Clavulanic Acid: This component inhibits beta-lactamase enzymes produced by some bacteria that can break down amoxicillin. By blocking these enzymes, clavulanic acid allows amoxicillin to work effectively against resistant strains.

The combination provides a broader spectrum of activity, treating infections caused by bacteria resistant to amoxicillin alone.

What infections does amoxicillin clav 875/125 mg treat?

Amoxicillin clav 875/125 mg is used for various bacterial infections, particularly those caused by beta-lactamase-producing bacteria.

Common FDA-approved indications

Key uses, as approved by the FDA and supported by clinical guidelines, include:

  • Acute Bacterial Rhinosinusitis (Sinus Infection): Often a preferred initial treatment, especially over amoxicillin alone.
  • Acute Otitis Media (Ear Infection): Effective for bacterial ear infections, especially when resistance is a concern.
  • Lower Respiratory Tract Infections: Used for conditions like community-acquired pneumonia, particularly in patients with certain risk factors.
  • Skin and Soft Tissue Infections: Treats infections like cellulitis caused by beta-lactamase-producing bacteria.
  • Urinary Tract Infections (UTIs): Used for UTIs caused by susceptible bacteria.

Other uses

Beyond approved indications, it may be used off-label for conditions such as bite wounds, diabetic foot infections, dental infections, and exacerbations of COPD.

Amoxicillin vs. Amoxicillin Clavulanate: A comparison

Adding clavulanic acid to amoxicillin significantly impacts the bacteria the drug can target and its side effects. The table below highlights key differences:

Feature Amoxicillin (alone) Amoxicillin Clavulanate (e.g., 875/125 mg)
Active Ingredients Amoxicillin Amoxicillin + Clavulanic Acid
Mechanism of Action Inhibits bacterial cell wall synthesis Inhibits bacterial cell wall synthesis AND inactivates beta-lactamase enzymes
Bacterial Coverage Effective against a range of susceptible bacteria, but vulnerable to beta-lactamase producing strains Broader spectrum, effective against both susceptible and many beta-lactamase producing bacteria
Indications Often first-line for common infections like ear infections or strep throat caused by susceptible strains Preferred for infections where bacterial resistance is suspected or confirmed
Gastrointestinal Side Effects Generally milder GI upset Higher incidence of gastrointestinal issues like diarrhea and nausea
Risk of Resistance Increased risk of treatment failure if resistance is present Helps overcome resistance, but overprescription can still contribute to resistance development

Important considerations when taking this medication

Proper use of amoxicillin clav 875/125 mg is essential. Always follow your doctor's instructions.

  • Finish the prescription: Do not stop taking the medication early, even if symptoms improve, as this can lead to antibiotic resistance.
  • Take with food: Consuming with a meal can reduce gastrointestinal side effects like nausea and diarrhea.
  • C. difficile risk: A less common but serious side effect is Clostridium difficile-associated diarrhea (CDAD). Seek medical attention for severe, watery diarrhea.
  • Allergies: Inform your doctor of any history of penicillin allergy as severe allergic reactions are possible.
  • Organ function: Dosage adjustments may be needed for individuals with liver or kidney issues.

Conclusion

Amoxicillin clav 875/125 mg is a combination antibiotic effective against a range of bacterial infections, including those resistant to amoxicillin alone. Its ability to overcome bacterial resistance makes it valuable for conditions like sinusitis and pneumonia. To maintain its effectiveness and combat resistance, it's crucial to take the full prescribed course and be aware of potential side effects. Consult a healthcare professional for diagnosis and treatment. For detailed information, refer to the official FDA prescribing information for Augmentin.

Frequently Asked Questions

It is typically taken by mouth with a meal or snack every 12 hours (twice a day) to minimize stomach upset. It's crucial to take it exactly as prescribed by your doctor and to finish the entire course of medication.

Amoxicillin clavulanate contains clavulanic acid, which helps amoxicillin fight bacteria that have become resistant to amoxicillin alone. The plain amoxicillin is not protected against these resistant bacteria.

No, like all antibiotics, amoxicillin clavulanate is only effective against bacterial infections and will not treat viral infections such as colds or the flu.

Common side effects include diarrhea, nausea, vomiting, and skin rash. Taking the medication with food can help reduce stomach upset.

Take the missed dose as soon as you remember. However, if it is almost time for your next dose, skip the missed dose and continue your regular schedule. Do not take a double dose.

Yes, amoxicillin clavulanate may decrease the effectiveness of oral birth control pills. It is recommended to use an alternative method of contraception while taking this medication.

The combination of amoxicillin and clavulanic acid is generally considered a Pregnancy Category B drug, but it should only be used if clearly needed and under a doctor's supervision.

Yes, serious side effects can occur, including severe allergic reactions (anaphylaxis), liver problems, and Clostridium difficile diarrhea. Seek immediate medical attention if you experience severe symptoms.
