Meet Meresa ⌄
Meresa is a prefilled device that delivers a measured dose of semaglutide under your skin once a week. It is designed to be used at home after your clinician shows you how it works.
- Used once weekly on the same day.
- Available in multiple strengths so your dose can be adjusted gradually.
- Intended to be used alongside a reduced‑calorie diet and increased activity.
About the ingredients ⌄
Each Meresa pen contains semaglutide, a GLP‑1 receptor agonist, along with inactive ingredients that keep the medication stable and ready to inject.
- Active ingredient: semaglutide, a GLP‑1 receptor agonist used in other weight‑loss medications.
- Inactive ingredients: stabilizers and sterile water for injection.
- Tell your clinician about any allergies to medication ingredients before starting.
How to take Meresa ⌄
You inject Meresa once a week, with or without food, into the skin of your stomach, thigh, or upper arm, as directed by your clinician.
- Choose a weekly injection day and stick with it.
- Rotate injection sites to help reduce irritation.
- If you miss a dose, follow your clinician’s instructions rather than taking extra doses.
Most people start on a lower dose that is increased slowly over time to help your body adjust.
