Summary
The extracted claims make many specific, constipation-related assertions (incidence %, timing, severity, dose-response, mechanisms, cross-drug comparisons, and management guidance) that are not supported by the provided FDA label excerpts.
Category Scores
Accurate Statements
Follow dosage escalation after 2.5 mg initiation to reduce the risk of gastrointestinal adverse reactions.
Supported by label excerpt: “Follow the dosage escalation below to reduce the risk of gastrointestinal adverse reactions…” in 2.1 Recommended Dosage.
Unsupported Statements
Mounjaro lists constipation as a common gastrointestinal side effect.
No constipation frequency/wording is present in the provided label excerpts.
In clinical trials, constipation occurred in 6-7% of patients taking Mounjaro.
No constipation incidence percentages are present in the provided excerpts.
In clinical trials, constipation was typically mild.
No severity characterization for constipation appears in the provided excerpts.
In clinical trials, constipation typically occurred early in treatment.
No timing information for constipation appears in the provided excerpts.
Nausea occurred in up to 20% of patients in the clinical trials.
No nausea incidence values are present in the provided excerpts.
Diarrhea occurred in 12-13% of patients in the clinical trials.
No diarrhea incidence values are present in the provided excerpts.
Constipation on Mounjaro is reported alongside slowed stomach emptying.
No linkage between constipation and gastric emptying is included in the provided excerpts.
SURMOUNT-1 constipation occurred in 6.3% (5 mg), 6.8% (10 mg), 7.1% (15 mg), and 1% (placebo).
No SURMOUNT-1 dose-specific constipation percentages are present in the provided excerpts.
SURPASS constipation rates were 5-12% across doses.
No SURPASS constipation rates are present in the provided excerpts.
Tirzepatide delays gastric emptying.
No mechanism statements are present in the provided excerpts (12 Clinical Pharmacology section content not shown).
Tirzepatide reduces gut motility.
No gut motility statements are present in the provided excerpts.
Tirzepatide delays gastric emptying to promote fullness and weight loss.
No mechanistic link to fullness/weight loss is present in the provided excerpts.
Mechanism shared with GLP-1 drugs can harden stools or reduce bowel frequency.
No GLP-1 comparative mechanism or stool/bowel frequency statements are present in the provided excerpts.
Higher doses (10-15 mg) correlate with more cases of constipation.
No dose-response correlation language appears in the provided excerpts.
Constipation often resolves in 4-8 weeks as the body adjusts.
No constipation resolution timeline is present in the provided excerpts.
Most cases of constipation are transient.
No transient characterization is present in the provided excerpts.
Constipation peaks in weeks 1-4 and fades by week 12.
No constipation peak or week-by-week resolution information is present in the provided excerpts.
Starting at 2.5 mg minimizes the risk of constipation.
Label excerpt supports GI adverse reactions risk reduction via titration, but does not specifically state constipation risk minimization.
Severe or persistent constipation warrants medical review for dehydration or impaction.
No constipation-specific management guidance is present in the provided excerpts.
A table lists Mounjaro constipation rate as 6-12%, Ozempic/Wegovy as 5-7%, and Zepbound as 6-7%.
No table or comparative constipation rate ranges are present in the provided excerpts.
The table states Ozempic/Wegovy often have less constipation and more nausea/diarrhea.
No comparative table statements are present in the provided excerpts.
The table states Zepbound and Mounjaro contain the same molecule (tirzepatide).
No such table statement is present in the provided excerpts.
Patients switching from semaglutide report comparable or slightly worse constipation on Mounjaro due to GIP action.
No switching data or GIP attribution is present in the provided excerpts.
Rarely (<1%), constipation can signal ileus (bowel obstruction).
No ileus/bowel obstruction linkage to constipation with that frequency is present in the provided excerpts.
Constipation can be associated with pancreatitis (rarely).
While pancreatitis is listed as a serious adverse reaction category, the provided excerpts do not state constipation-pancreatitis association.
Advise stopping and seeking ER if constipation is accompanied by vomiting, severe pain, or no bowel movement for 3+ days.
No such specific instruction appears in the provided excerpts.
Patients with prior GI issues (e.g., IBS) face higher risk of constipation.
No statement about increased constipation risk in patients with prior GI conditions is present in the provided excerpts.
No link to long-term colon issues in trials up to 72 weeks was reported.
No long-term colon outcome statements or 72-week trial reporting are present in the provided excerpts.
Contradictions
Important Omissions
The provided label excerpts do not include constipation adverse reaction frequency, severity, timing, or management instructions; therefore, any attempt to quantify or characterize constipation in detail is not supported by the provided label content.
Importance:
High
Safety Assessment
Potential Patient Risk:
High

Primary Issue
Constipation-specific quantitative and mechanistic claims are not supported by the provided label excerpts.
Suggested Improvement
Limit claims to label-supported information present in the provided excerpts (e.g., titration intended to reduce risk of gastrointestinal adverse reactions) and remove unsupported constipation incidence/timing/mechanism/comparative-brand-table and emergency management instructions unless the relevant label text is provided.
