What is the primary adverse effect of Plan B and how is it managed if emesis occurs within 2 hours?

Explanation:
Plan B (levonorgestrel) commonly causes nausea. If vomiting occurs within 2 hours of taking it, absorption may be incomplete, so a second dose should be given as soon as possible to ensure adequate drug exposure. Headache, dizziness, and fatigue can occur but are not the primary issue here, and they don’t require the specific redosing step after early emesis. So, addressing nausea as the main adverse effect and using a redose if emesis happens within 2 hours best matches the intended management.
