Mastering Semaglutide: A Step-by-Step Guide to Reconstitution

Semaglutide is a glucagon-like peptide-1 receptor agonist that is used to treat type 2 diabetes and obesity. As an incretin mimetic, semaglutide is a very effective weight-loss medication. In clinical trials, participants taking Wegovy (a brand name for semaglutide) had an average weight loss of 10% to 16% of their starting body weight. Those who received Wegovy lost an average of 34 pounds. The placebo group participants lost about 2.5% of their body weight, about six pounds.

The U.S. Food & Drug Administration allows manufacturers to compound semaglutide if there is a drug shortage. Compounded medications must meet certain Federal Food, Drug, and Cosmetic (FD&C) Act requirements. As of May 2023, Wegovy is listed on FDA’s Drug Shortages list.

With the compounded form of semaglutide, patients may need to reconstitute the medication before injecting it. This straightforward procedure involves adding a diluent and mixing the solution.

Does semaglutide need to be reconstituted?

This depends on whether you are using the brand name Wegovy or compounded semaglutide. If your doctor has prescribed the brand name Wegovy, you will receive a pen injector that is prefilled with the appropriate medication dose.

If your doctor prescribes compounded semaglutide, you will probably need to reconstitute it and inject it with a small insulin syringe, though some pharmacies ship semaglutide already reconstituted.

How do you reconstitute a medication?

If your medication comes in a powdered form, it will need to be reconstituted or put in a liquid before it can be injected.

Here are the steps to follow to reconstitute a medication such as semaglutide:

  • Gather your supplies: the medication vial, the diluent, a syringe and needle, two alcohol prep pads, and the instructions from your pharmacy.
  • Determine the amount of diluent to add: the medication instructions should indicate how much diluent should be added to the vial. If they do not, contact your pharmacist. If you do not add the correct amount of diluent, then your dosage will not be correct.
  • Draw up the diluent: remove the cap from the diluent vial and clean the rubber membrane using an alcohol prep pad. Uncap the needle and pull back on the plunger to fill the syringe with air. Add air to just pass the amount of diluent you need to add to your medication. Insert the needle into the diluent bottle, inject the air into the vial, and fill the syringe with the correct amount of diluent.
  • Add diluent to the medication: Clean your medication vial with the second alcohol prep pad. Insert the syringe containing the diluent into the medication vial and inject the diluent into the vial.
  • Mix the medication vial: Gently roll the medication vial to completely mix the powdered medication with the diluent.
  • Store your medication: Follow the medication instructions for storage. Some medications require refrigeration after reconstitution, and some are kept at room temperature.

How is semaglutide dosed?

Semaglutide is dosed using a gradually increasing dose. This is designed to minimize the gastrointestinal side effects associated with GLP-1 receptor agonists.

Semaglutide has a maximum dose of 2.4 mg per week.

Following your healthcare provider’s instructions, semaglutide is typically dosed according to the following schedule:

WeekDosage
10.25mg
20.25mg
30.25mg
40.25mg
50.5mg
60.5mg
70.5mg
80.5mg
91mg
101mg
111mg
121mg
131.7mg
141.7mg
151.7mg
161.7mg
172.4mg
182.4mg
192.4mg
202.4mg

Before injecting semaglutide, verify that the medication is clear and colorless. Check the expiration date. Verify your prescribed dose. Consider adding doses to a calendar to keep track while increasing your dose to the full 2.4 mg dose.

Who can take semaglutide?

With every medication, you must weigh the potential risks and benefits associated with taking the medication. Carrying excess weight increases your risk for type 2 diabetes, heart disease, and many other health issues.

Semaglutide is prescribed for people with a body mass index (BMI) of 30kg/m2 or higher. It can also be prescribed for people with a BMI of 27kg/m2 or higher if they have at least one comorbid condition that is associated with being overweight.

Wegovy (Semaglutide) Warnings

Wegovy (semaglutide) can cause serious health problems, particularly in people who are predisposed to these conditions.

It is unclear whether people would have a similar risk. Tell your doctor if you notice a lump in your neck, hoarseness, difficulty swallowing, or shortness of breath.
  • Pancreatitis: discontinue Wegovy and call your doctor if you develop stomach pain that radiates to your back and may be accompanied by fever, nausea, or vomiting.
  • Gallbladder disease: gallstones and gallbladder disease can cause upper abdominal pain and yellowing of the skin or eyes.
