What the Mounjaro label says

  • Mounjaro may make birth control pills less effective because it slows stomach emptying.[1]
  • With a pill, switch to a non-oral method or add a barrier method for 4 weeks after starting and for 4 weeks after each dose increase.[1]
  • Hormonal methods that are not taken by mouth should not be affected.[1]
  • In the label's study, a first 5 mg dose lowered the pill hormones' peak levels by 55% to 66% and their total exposure by 20% to 23%.[1]
  • Tell your prescriber if you are pregnant or intend to become pregnant.[1]
