Semaglutide slows gastric emptying and may reduce pill absorption if taken simultaneously. Birth control efficacy may decrease slightly (estimated 5-10% reduction in absorption). Mitigation: take pill 30+ minutes before semaglutide injection, or use separate timing. No major documented failures, but caution warranted. Consider backup contraception if concerned.
