What does clavulanic acid do?

It blocks the enzyme some bacteria use to destroy amoxicillin, so the antibiotic keeps working against them. It is not an antibiotic on its own.

Can I take amoxicillin if I am allergic to penicillin?

No. Amoxicillin is a penicillin. Tell your doctor about the allergy so a different class can be chosen.

Why is a course seven days for one infection and five for another?

Course length is set by the infection and the site, and is part of the prescription.
