Amoxicillin-Clavulanate Dosage for Bladder Infections (UTIs)

For uncomplicated bladder infections (cystitis), typical adult dosing of amoxicillin-clavulanate (Augmentin) is:

• 500 mg/125 mg every 12 hours for 5–7 days, OR
• 875 mg/125 mg every 12 hours for 5–7 days.

The higher dose (875 mg) is often preferred for better coverage of resistant bacteria. For complicated UTIs or pyelonephritis, treatment may extend to 10–14 days.

Important Considerations

• Always follow your prescriber's exact instructions. Dose may vary by infection severity, kidney function, local resistance patterns, and patient factors.
• Take with food to reduce stomach upset.
• Complete the full course even if symptoms improve.
• Report allergic reactions (rash, swelling, difficulty breathing) immediately.

This antibiotic combines amoxicillin with clavulanate to overcome beta-lactamase resistance. It is not first-line for all UTIs; trimethoprim-sulfamethoxazole or nitrofurantoin may be preferred depending on guidelines and allergies.
