How long does it take for periods to normalise after starting Mounjaro?

Most period changes after starting Mounjaro occur within the first 1 to 3 months and resolve over time as the body adjusts. These changes typically settle after a few months. Side effects from starting or increasing the dose subside within 2-3 weeks, helping the menstrual cycle regulate.

Key points:

  • Rapid weight loss from Mounjaro indirectly causes menstrual changes.
  • Hormonal shifts due to weight loss affect cycle regularity.
  • Changes often resolve as the body adjusts to the medication.
  • Improved insulin sensitivity can influence periods, especially in PCOS.
