Patient Question

Hello Doctor,


Can stomach upset and bowel movements affect the effectiveness of Postinor 2? I took it about 3 hours ago.



Thank you for reaching out to Dr. Galen. Please find the below response to your query.


Usually, Postinor 2 is absorbed within 2-3 hours. However, if you experience diarrhea, it can affect the absorption of the medication. The active ingredients may not be fully absorbed into your bloodstream and could be lost in the stool. In such cases, it's advisable to take another dose immediately, provided you do not experience diarrhea again. This ensures that you receive the full dose and maintains its effectiveness in preventing pregnancy.
