Standard amoxicillin dosage for uncomplicated UTIs in adults typically ranges from 500mg to 875mg, taken twice daily for 7-10 days. However, your doctor will personalize your treatment based on several key factors.
Severity and Type of Infection
The severity of your UTI and the specific bacteria causing the infection significantly impact the prescribed dosage and duration. More severe infections or those caused by resistant bacteria might require higher doses or a longer treatment course. Your doctor will perform a urine culture to identify the responsible bacteria and determine its susceptibility to amoxicillin.
Kidney Function
Your kidney’s ability to filter waste products, including medication, influences dosage. Individuals with impaired kidney function may require lower doses or less frequent administration to avoid medication buildup. Creatinine clearance tests help doctors assess kidney function and adjust prescriptions accordingly.
Patient Characteristics
Other individual factors, such as age, weight, and overall health, can also affect dosage. For example, elderly patients or those with other underlying health conditions might need modified dosages to minimize side effects or maximize efficacy.
Potential Drug Interactions
Amoxicillin can interact with certain medications. Inform your doctor about all medications you are currently taking, including over-the-counter drugs and herbal supplements. This allows them to identify any potential interactions and make necessary adjustments to your amoxicillin dosage or choose an alternative antibiotic.
Allergic Reactions
Prior allergic reactions to penicillin-based antibiotics are a strong contraindication for amoxicillin use. If you have a history of penicillin allergies, your doctor will likely prescribe a different antibiotic.
