Midwives may independently prescribe, order and administer this drug.

Amoxicillin inhibits bacterial cell wall synthesis by binding to one or more of the penicillin-binding proteins which in turn inhibits the final transpeptidation step of peptidoglycan synthesis in bacterial cell walls, thus inhibiting cell wall biosynthesis.

Indications and Clinical Use:

Documented hypersensitivity or allergy to amoxicillin, other beta-lactam antibacterial drugs or any components of their formulation.

Warnings and Precautions:

Reduces efficacy of oral contraceptives; adjust dose in renal impairment; may enhance chance of candidiasis.
