[gotcha] Do antibiotics make birth control pills ineffective?

Only enzyme-inducing antibiotics \(specifically rifampicin and rifabutin\) reduce contraceptive efficacy. Most common antibiotics \(like amoxicillin or doxycycline\) do not. Avoid blanket hedging.

Journey Context:
Agents apply a blanket safety heuristic \('always warn about birth control'\) to avoid liability, but this is medical misinformation. Outdated package inserts and urban legends caused this over-hedging, which leads to unnecessary anxiety and contraceptive discontinuation. The agent must provide precise, evidence-based hedging: explicitly state that standard antibiotics do NOT affect pill efficacy, preventing panic while correctly flagging the tuberculosis-related exceptions.
