What are the main ingredients in wegovy and ozempic?

See the DrugPatentWatch profile for wegovy

Main Active Ingredient in Wegovy and Ozempic

Wegovy and Ozempic both contain semaglutide as their active ingredient. Semaglutide is a GLP-1 receptor agonist that mimics a hormone to regulate blood sugar, slow gastric emptying, and reduce appetite.[1]

How Wegovy and Ozempic Differ

Despite sharing semaglutide, they are formulated for different uses and doses:
- Ozempic: Approved for type 2 diabetes management; weekly doses up to 2 mg semaglutide.
- Wegovy: Approved for chronic weight management; higher weekly doses up to 2.4 mg semaglutide.
Inactive ingredients are similar but vary slightly by dose and pen design, including disodium phosphate dihydrate, propylene glycol, phenol, and water for injection.[1][2]

Full Ingredient Lists

Ozempic (per 0.25 mg/0.5 mg dose example)

  • Active: Semaglutide 0.25 mg or 0.5 mg
  • Inactive: Disodium phosphate dihydrate, propylene glycol, phenol, water for injections.[2]

Wegovy (per 0.25 mg dose example; higher doses scale semaglutide)

  • Active: Semaglutide 0.25 mg (up to 2.4 mg in other pens)
  • Inactive: Disodium phosphate dihydrate, propylene glycol, phenol, water for injections.[1]

    These lists come from official prescribing information; check product labels for exact dose-specific formulations.

Why the Same Drug, Different Brands?

Novo Nordisk manufactures both under separate FDA approvals. Semaglutide's patents protect the molecule until around 2031-2033 in the US, delaying generics.[3] No generics exist yet.

Common Patient Questions on Ingredients

Patients often ask if ingredients cause allergies—phenol acts as a preservative, and propylene glycol may trigger rare reactions. Semaglutide itself rarely causes hypersensitivity.[1][2]

Summary

Major non-verifiable/likely incorrect Ozempic-related claims were marked absent from label without Ozempic label citations, creating label-content mismatch risk. Additionally, key safety-critical label sections (contraindications, boxed warnings/warnings & precautions, pregnancy/lactation, and pediatrics) were not evaluated against the provided label text, which is a material audit omission.

Unsupported Statements

Ozempic contains semaglutide as its active ingredient.
No Ozempic label section was provided for verification; the claim was evaluated as 'absent_from_label' without Ozempic-specific label citations.
Ozempic is approved for type 2 diabetes management.
No Ozempic label section was provided for verification; the claim was evaluated as 'absent_from_label' without Ozempic-specific label citations.
Ozempic weekly doses are up to 2 mg semaglutide.
No Ozempic label section was provided for verification; dosing maximum assertions require label-text verification by Ozempic strength/dose table.
Ozempic (example 0.25 mg/0.5 mg dose) has active semaglutide 0.25 mg or 0.5 mg.
Strength/concentration and active-ingredient quantity statements require Ozempic label citations; none were provided.
Ozempic (example 0.25 mg/0.5 mg dose) has inactive ingredients: disodium phosphate dihydrate, propylene glycol, phenol, and water for injections.
Excipients by specific set/dose require Ozempic label citations; none were provided.
Novo Nordisk manufactures both Wegovy and Ozempic.
No label section provided for manufacturing attribution; claim was not label-verifiable from provided Wegovy sections.
Wegovy and Ozempic are manufactured under separate FDA approvals.
Not substantiated by the provided label text; no FDA approval-manufacturing-structure language was provided.
Semaglutide patents protect the molecule until around 2031-2033 in the US.
Patent life/generics-delay assertions are not supported by the provided prescribing information sections.
Semaglutide patents delay generics.
Not supported by the provided prescribing information sections.
No generics exist yet.
Not supported by the provided prescribing information sections.
Phenol acts as a preservative.
The provided label section lists phenol as an inactive ingredient but does not state preservative function; no functional excipient statement was cited.
Propylene glycol may trigger rare reactions.
Not supported in provided label sections (no excipient reaction association text cited).

Frequency/rarity language was not supported by the provided sections; hypersensitivity is described without rarity quantification.

Contradictions


Important Omissions

Contraindications (explicit agreement with contraindication statement(s) relevant to safety).
Importance: High
Boxed warning status and/or boxed warning content (if any) and warnings & precautions comprehensive check (e.g., hypersensitivity handling, severe GI reactions, gastroparesis limitation).
Importance: High
Use in specific populations (e.g., pregnancy/lactation and other population warnings/limitations, as applicable to the product).
Importance: High
Ozempic dosing/administration/safety label verification for any strength-specific or maximum dose claims.
Importance: High

Safety Assessment

Potential Patient Risk: High
The response includes multiple drug-identification/approval/dose-limit claims for Ozempic without Ozempic label citations and contains unverified excipient functional and hypersensitivity rarity statements. It also fails to evaluate key contraindication and warnings sections, which are essential for safe label adherence.

Regulatory Assessment

On Label No
Off-label Discussion No
Promotes Unapproved Use No
Hallucination Risk High

Recommendation

Not Aligned

Primary Issue
Ozempic-related claims were marked absent_from_label and/or unverified without any Ozempic prescribing information citations, and key safety-critical label sections were not evaluated.

Suggested Improvement
Provide and cite the relevant Ozempic label sections for any Ozempic-specific claims (active ingredient, indication, dose limits, excipients). Evaluate contraindications, warnings/precautions, and specific-population sections before concluding support/absence. Remove or re-cite any excipient functional/rareness and patent/generics assertions, since these are not supported by the provided prescribing information text.
