Augmentin (Amoxicillin/Clavulanate) Dosing with GFR of 57 mL/min/1.73m²

Yes, you can safely take Augmentin with a GFR of 57 mL/min/1.73m² without dose adjustment, as this level of renal function is considered mild impairment and does not require modification of the standard dosing regimen. 1

Understanding Renal Function and Medication Dosing

A GFR of 57 mL/min/1.73m² falls into the category of mild-to-moderate renal impairment (GFR category G3a: 45-59 mL/min/1.73m²). According to the KDOQI guidelines, this level of kidney function requires consideration for medication dosing, but many medications can still be used at standard doses.

Augmentin-Specific Considerations:

  • Amoxicillin and clavulanic acid (the components of Augmentin) are primarily excreted by the kidneys
  • Dose adjustment is generally not required until GFR falls below 30 mL/min/1.73m²
  • With your GFR of 57, standard dosing is appropriate

Dosing Recommendations Based on Renal Function

GFR Range (mL/min/1.73m²) Augmentin Dosing Recommendation
>60 (Normal to mild) Standard dosing
30-60 (Moderate) Standard dosing
10-30 (Severe) Reduced dose or extended interval
<10 (Kidney failure) Significantly reduced dose

Monitoring Recommendations

While taking Augmentin with your current renal function:

  • Monitor for signs of efficacy (improvement in infection symptoms)
  • Watch for potential side effects (gastrointestinal disturbances, rash)
  • Be aware of potential drug interactions
  • Consider periodic assessment of kidney function if on extended therapy

Important Precautions

  1. Temporary suspension of medication may be warranted during:

    • Acute illness with dehydration
    • Before procedures with IV contrast
    • Episodes of acute kidney injury
  2. Avoid concurrent use of other potentially nephrotoxic medications when possible, particularly:

    • NSAIDs (ibuprofen, naproxen)
    • Certain diuretics
    • Other medications that may affect kidney function

When to Seek Medical Attention

Contact your healthcare provider if you experience:

  • Worsening kidney function
  • Signs of allergic reaction
  • Severe diarrhea
  • No improvement in infection symptoms after 2-3 days

Remember that while your current GFR of 57 allows for standard Augmentin dosing, any significant decline in kidney function may necessitate dose adjustment in the future.
