amoxicillin clavulanate prescribing information renal impairment dosage 875 creatinine clearance

Amoxyclav (amoxicillin-clavulanate) can be used in CKD, but the dose must be adjusted when kidney function is significantly reduced. Do not self-start it without a clinician checking your creatinine/eGFR and the reason for infection.
  • eGFR/GFR 30 mL/min or higher: usual dosing is generally acceptable.
  • eGFR/GFR 10-30: lower-strength tablet/suspension is usually given every 12 hours.
  • eGFR/GFR under 10: lower-strength form is usually given every 24 hours.
  • Avoid the 875/125 mg tablet if eGFR/GFR is under 30 mL/min.
  • On hemodialysis: a specific schedule and extra dose around dialysis may be needed.
The drug is cleared mainly through the kidneys, so taking an unadjusted dose in advanced CKD can increase side effects, including nausea, diarrhea, rash, and rarely kidney inflammation or seizures.
This matches the DailyMed prescribing information, and medical texts also state that amoxicillin-clavulanate doses require adjustment in impaired renal clearance.
If you share the tablet strength, your latest creatinine/eGFR, and whether you are on dialysis, I can help interpret whether the prescribed regimen fits the label.

antibiotic renal dosing chronic kidney disease nephrotoxic antibiotics guideline

There is no single antibiotic that is safe for every person with CKD. The right choice depends on the infection site, severity, culture result, allergies, and your eGFR/creatinine clearance. Many antibiotics are usable in CKD if the dose or interval is adjusted.
Antibiotics that usually do not need renal dose adjustment
  • Azithromycin
  • Doxycycline
  • Ceftriaxone (often used by injection)
  • Clindamycin
  • Linezolid
  • Nafcillin (hospital IV antibiotic)
Medical reference text lists nafcillin, ceftriaxone, doxycycline, azithromycin, and linezolid among antimicrobials not requiring renal-dose adjustment.
Often safe, but dose adjustment is commonly needed
  • Amoxicillin / Amoxyclav
  • Cephalexin, cefuroxime, cefixime, cefpodoxime, cefepime
  • Ciprofloxacin, levofloxacin
  • Co-trimoxazole / TMP-SMX
  • Piperacillin-tazobactam
  • Meropenem
Use cautiously or generally avoid unless closely monitored
  • Aminoglycosides: gentamicin, amikacin, tobramycin. They can damage kidneys.
  • Vancomycin: can be used, but requires drug-level and kidney-function monitoring.
  • TMP-SMX: may raise potassium and creatinine, especially with ACE inhibitors/ARBs or spironolactone.
  • Nitrofurantoin: generally not used when eGFR is below 30 mL/min/1.73 m² because it may not work adequately for UTI and side effects can increase.
For CKD, do not select an antibiotic only because it is “kidney-safe.” The dose must match your eGFR. The National Kidney Foundation medication guidance explains that many infection medicines can accumulate in CKD but can still often be used at a lower dose or less frequently.
If you tell me:
  1. your eGFR or creatinine,
  2. whether you are on dialysis, and
  3. the suspected infection, such as UTI, throat, chest, dental, or skin,
I can help identify which common options are usually considered and which need avoidance or dose adjustment.

KDIGO 2024 CKD blood pressure ACE inhibitor ARB albuminuria guidance

For people with CKD and high blood pressure, several medicines are safe and commonly used. The best option depends especially on whether there is protein/albumin in the urine, diabetes, heart failure, potassium level, swelling, and eGFR.

Often preferred in CKD

  1. ACE inhibitors
    Examples: ramipril, lisinopril, enalapril
    Often first choice if urine protein/albumin is high, because they lower BP and help protect kidneys.
  2. ARBs
    Examples: losartan, telmisartan, valsartan
    Similar kidney benefit to ACE inhibitors and often used if ACE inhibitors cause cough.
    Take either an ACE inhibitor or an ARB, not both together. Kidney function and potassium should be rechecked about 2 to 3 weeks after starting or increasing the dose. A small initial creatinine rise can occur; a rise of more than 30% needs medical review.
  3. Calcium-channel blockers
    Examples: amlodipine, nifedipine
    Generally safe at all CKD stages and commonly added when BP remains high. Amlodipine may cause ankle swelling.
  4. Diuretics ("water tablets")
    • Chlorthalidone, indapamide, hydrochlorothiazide: can work in mild to moderate CKD.
    • Furosemide, torsemide: often preferred if eGFR is low or there is leg swelling/fluid overload.
      These require monitoring of sodium, potassium, dehydration, and kidney function.
  5. Beta-blockers
    Examples: metoprolol, carvedilol, bisoprolol
    Useful when there is coronary artery disease, previous heart attack, heart failure, fast pulse, or arrhythmia. Some require dose adjustment in advanced CKD.

Important cautions

  • ACE inhibitor/ARB are usually continued even if eGFR is below 30, unless there is symptomatic low BP, uncontrolled high potassium, acute kidney injury, or a major creatinine rise. The KDIGO CKD guideline recommends ACEi/ARB particularly for CKD with moderate-to-severe albuminuria.
  • Avoid combining ACE inhibitor + ARB. This increases risks of acute kidney injury and high potassium.
  • Be cautious with spironolactone/eplerenone in CKD because potassium can become dangerously high. Use only with close lab monitoring.
  • Avoid NSAID painkillers such as ibuprofen, diclofenac, and naproxen, especially when taking an ACEi/ARB plus a diuretic. This combination can abruptly worsen kidney function.
  • Do not stop prescribed BP tablets suddenly without speaking to the prescriber.
Common combinations include:
  • Losartan or telmisartan + amlodipine
  • ACE inhibitor or ARB + diuretic
  • ACE inhibitor/ARB + amlodipine + diuretic when BP is difficult to control
Please share your current BP readings, eGFR/creatinine, urine protein report, potassium value, and current BP medicines for safer, more specific guidance.
