What counts as a “high dose” of amoxicillin?
A typical adult dose of amoxicillin for many common infections is often in the range of 500 mg taken 2–3 times per day, depending on the condition. In that context, 875 mg per dose is generally considered a high-strength tablet/amount (a larger single dose than 500 mg).
Whether it’s “high” for you depends on the total daily dose and what infection is being treated, not just the per-dose number.
How does 875 mg translate into total daily dose?
875 mg per dose is usually written as part of a regimen like:
- 875 mg twice daily (total 1,750 mg/day), or
- 875 mg three times daily (total 2,625 mg/day)
Many standard adult regimens fall below those totals, so the twice- or thrice-daily versions are commonly viewed as higher-intensity dosing, especially for bacterial infections where higher doses are used.
Is it high for kids versus adults?
Dosing in children is typically weight-based (mg per kg per day), so “875 mg” by itself isn’t automatically “high” for pediatrics. A clinician would calculate the daily mg/kg target and then choose a practical tablet/liquid dose.
Why do doctors prescribe 875 mg?
Higher per-dose strengths like 875 mg are commonly used when prescribers want:
- higher exposure over the day (often by using higher dose and/or more frequent dosing), or
- to treat infections where guidelines recommend higher-dose amoxicillin.
The exact reason depends on the diagnosis (for example, certain ear/sinus/throat infections, dental infections, etc.).
When should you double-check with a clinician?
If you were expecting a lower dose (or if the prescription seems different from what you’ve taken before), it’s reasonable to confirm with the prescriber or pharmacist—especially if:
- you’re taking it for a child (weight-based dosing matters),
- you have kidney disease or reduced kidney function (dose may need adjustment),
- you’re unsure whether it’s amoxicillin alone or a combination product (some regimens are amoxicillin-clavulanate).
If you share your regimen, I can interpret it
If you tell me the exact prescription schedule (for example, “875 mg twice a day for 10 days”) and whether it’s for an adult or a child (and child’s weight, if applicable), I can help you gauge how it compares with common dosing ranges.
