A care home sends a MAR chart showing co-careldopa 25/100mg due at 08:00, 12:00, 16:00 and 20:00. The 12:00 dose was omitted yesterday because the medicines trolley arrived late, and the resident became rigid and confused by mid-afternoon. What is the most appropriate action?

Correct answer: C — treat co-careldopa as time-critical and escalate missed doses promptly

Levodopa preparations are time-critical medicines and delayed or omitted doses can cause marked deterioration. The care home needs a process to administer doses at the prescribed times and escalate missed doses. Combining doses later may cause adverse effects and does not correct wearing-off safely. Prochlorperazine can worsen Parkinsonian symptoms and is not a substitute.
