Wegovy ingredients list?

What’s in Wegovy (ingredients list)?

Wegovy (semaglutide) is a once-weekly injectable medicine. The active ingredient is semaglutide.

The product also contains inactive ingredients (excipients). The ingredients for Wegovy include:
- Lactose monohydrate
- Sodium chloride
- Trisodium citrate dihydrate
- Hydrochloric acid (for pH adjustment)
- Sodium hydroxide (for pH adjustment)
- Water for injection

Is semaglutide the only active ingredient?

Yes. Semaglutide is the only active ingredient in Wegovy. The rest of the listed components are inactive ingredients used to stabilize the drug and maintain the correct pH for the injection.

Are the inactive ingredients the same in every Wegovy strength?

The active ingredient stays the same (semaglutide), but the exact amount of excipients can vary by dose strength because the total formulation volume and concentration differ between pens.

Where can I find the official full ingredient list?

Important patient-use notes people often look for

Some patients ask about ingredients because of allergies and sensitivities:
- Lactose: Wegovy includes lactose monohydrate, which matters for people with lactose intolerance or specific sensitivities.
- pH adjusters: Hydrochloric acid and sodium hydroxide may be present in small amounts to control pH.
