Correct answer: C — Use a non-hormonal or specialist-recommended contraceptive strategy during and after rifampicin
Rifampicin is a potent enzyme inducer and can reduce exposure to hormonal contraceptives, risking contraceptive failure. The patient needs clear advice on reliable alternatives, such as non-hormonal methods, and duration after stopping should follow current contraception guidance. Doubling pills is not a safe or reliable solution. Rifampicin adherence is important for infection management.
