Correct answer: C — Keep alendronic acid outside the MDS with separate counselling on administration

Alendronic acid has strict administration requirements: take after getting up with water, before food and other medicines, and remain upright. It is usually unsuitable for routine inclusion in an MDS compartment with other medicines. Levothyroxine and calcium also require separation because calcium reduces levothyroxine absorption. Convenience must be balanced with clinically safe administration.
