1. Effectiveness Timeline:

   • Tranexamic acid typically reduces bleeding within a few days. If bleeding persists beyond three days, further evaluation is necessary.

2. When to Seek Medical Advice:

   • Persistent bleeding despite medication requires prompt consultation with a healthcare provider to rule out other causes or complications.

3. Additional Considerations:

   • The doctor may need to assess for other conditions, adjust medication, or consider alternative treatments.

Encourage your wife to contact her healthcare provider as soon as possible. If bleeding is heavy or accompanied by dizziness or weakness, seek emergency care immediately.
