Step-by-step explanation:

Diazepam is typically administered orally for systemic infections, as it is convenient and easy to administer at home. Diazepam is a medication belonging to the benzodiazepine class, and it is commonly used for its anxiolytic (anti-anxiety), sedative, muscle relaxant, and anticonvulsant properties.
