Correct answer: B — Take the missed dose when remembered unless it is close to the next dose

Missed-dose advice depends on the dosing schedule and timing, but doubling doses can increase adverse effects. For many regular medicines, taking the dose when remembered is reasonable unless it is close to the next scheduled dose. Patients with epilepsy should be counselled on adherence because missed doses may increase seizure risk. Individualised advice should follow the patient information leaflet or specialist plan.
