Timing facts from the trials and label

  • In pooled STEP 1 to 3, constipation was reported by 24.2% on semaglutide 2.4 mg and 11.1% on placebo over 68 weeks.[1]
  • The share with constipation plateaued at about week 10, and a constipation episode lasted a median of 47 days on semaglutide vs 35 on placebo.[1]
  • In STEP 4, constipation became less common over time in people who continued 2.4 mg.[1]
  • The label says stomach side effects were most often reported during dose escalation.[2]
  • After approval, ileus, intestinal obstruction and severe constipation including fecal impaction have been reported with semaglutide.[2]

Call instead of waiting for the next step

  • Severe stomach pain that will not go away, with or without vomiting: stop Wegovy and call your healthcare provider right away.[2]
  • Stomach problems that are severe or will not go away: tell your healthcare provider.[2]
  • Upper stomach pain, fever, yellow skin or eyes, or clay-colored stools: call your healthcare provider.[2]

When you bring the diary

  1. Does my pattern look like it is settling, or getting worse with each dose step?
  2. Should the next increase wait until my bowels are more regular?
  3. Which laxative suits me, and for how long?
  4. Could another of my medicines be adding to the constipation?
