What the two labels say

  • Zepbound slows stomach emptying and may affect the absorption of medicines taken by mouth at the same time.[1]
  • In the Zepbound label's study, a first 5 mg dose lowered oral contraceptive hormone peaks by 55% to 66% and total exposure by 20% to 23%.[1]
  • For contraceptive pills, the Zepbound label advises switching to a non-oral method, or adding a barrier method, for 4 weeks after starting and for 4 weeks after each dose increase. Hormonal contraceptives not taken by mouth should not be affected.[1]
  • Prometrium is taken as one dose at bedtime. Blood levels peak within 3 hours, and food increases absorption compared with an empty stomach.[2]
  • To protect the womb lining, the Prometrium label dose is 200 mg at bedtime for 12 days of each 28-day cycle, alongside daily conjugated estrogens.[2]

Contact a clinician promptly

  • Unusual vaginal bleeding while taking progesterone.[2]
  • Severe stomach pain that will not go away, with or without nausea or vomiting: stop Zepbound and call your healthcare provider right away.[1]
  • Vomiting or diarrhea that stops you keeping fluids down: loss of fluids can cause kidney problems.[1]

Questions for your prescriber

  1. Is my current progesterone route still the best fit now that I take Zepbound?
  2. Does anything need to change in the weeks after I start Zepbound or increase the dose?
  3. If I vomit soon after an oral progesterone dose, should I take another or wait for the next one?
  4. What bleeding pattern should I expect on my regimen, and what should I report?
  5. As my weight changes, when should we review my estrogen dose and the rest of the regimen?
