Final answer:
The package insert section providing information on drug allergies for Augmentin 875mg is the 'Contraindications' section, which relates to known severe allergic reactions, including penicillin allergies.
Step-by-step explanation:
The section of the package insert that provides information about drug allergies is Contraindications. This section includes important information on when the drug should not be used, which typically includes any known severe allergic reactions, such as an allergy to penicillin in the case of Mrs. Roberts being prescribed Augmentin 875mg.
Since Augmentin is a combination antibiotic containing amoxicillin (a penicillin derivative) and clavulanic acid, it could cause a severe allergic reaction in someone with a penicillin allergy. Therefore, the answer to the question is D) Contraindications.
