Mixing ‘votre’ (formal) with the informal imperative ‘Assure‑toi’ creates a register clash.

Cultural Tip
In French‑speaking countries, doctors stress the importance of completing the full antibiotic course to prevent resistance. It’s considered polite to follow this advice, and patients often receive a written reminder on the prescription label. Using the informal ‘tu’ form (as in this sentence) is appropriate when speaking with a peer, a family member, or a child; with adults you don’t know well, switch to the formal ‘vous’ (e.g., ‘Assurez‑vous de finir…’).
