Amoxicillin liquid concentration?

Amoxicillin oral suspension (the liquid) comes in a few common concentrations. The label on the bottle will show the exact amount per volume. Common ones are:

- 125 mg per 5 mL (25 mg/mL)
- 250 mg per 5 mL (50 mg/mL)

Some brands also offer 400 mg per 5 mL (80 mg/mL).

If you’re looking at amoxicillin-clavulanate (the Augmentin suspension), those are different: for example, 200 mg amoxicillin/5 mL with 28.5 mg clavulanate per 5 mL, or 400 mg amoxicillin/5 mL with 57 mg clavulanate per 5 mL.

How to read your bottle: check the label for something like “X mg/5 mL” or “X mg/mL.” If you tell me the exact brand or share the label text, I can confirm the concentration for you.

Note: If you have a powder that needs reconstitution, the label will specify the final concentration after mixing and how long it’s stable. Always use the exact concentration your product provides.
