[gotcha] Antibiotics reducing contraceptive pill effectiveness

Do not warn that broad-spectrum antibiotics \(e.g., amoxicillin\) reduce oral contraceptive efficacy. Only enzyme-inducing antibiotics \(e.g., rifampicin\) require additional contraception.

Journey Context:
For decades, medical dogma stated that antibiotics interfere with the pill by altering gut flora. This myth is deeply embedded in training data. The WHO and CDC have updated guidelines stating that except for enzyme inducers, there is no pharmacokinetic interaction. Agents repeating the old myth cause unnecessary anxiety, pill discontinuation, and emergency contraception use.
