Correct answer: E — Label with the appropriate after-reconstitution expiry and storage advice

Reconstituted antibiotic liquids often have a limited expiry and specific storage requirements. The dispensing label and counselling must reflect the prepared product's stability rather than the unopened pack expiry. This prevents ineffective or unsafe use near the end of treatment.
