Below is detailed information about dosage and administration for Wegovy.
Wegovy comes as a solution inside prefilled, single-dose pens. It’s given as a subcutaneous injection.
Wegovy solution is available in pens containing the following strengths:
- 0.25 milligrams of drug per 0.5 milliliters of solution (0.25 mg/0.5 mL)
- 0.5 mg/0.5 mL
- 1 mg/0.5 mL
- 1.7 mg/0.75 mL
- 2.4 mg/0.75 mL
It’s important to note that there are not multiple doses per pen. Each Wegovy pen delivers only a single dose. You’ll need to use a new pen for each dose of Wegovy.
Wegovy requires a dose escalation. This means your doctor will start you on a specific starting dose. Then, they’ll adjust it over time to reach the drug’s maximum dose.
The dose schedule described below is the typical Wegovy dose escalation. That said, your treatment plan may vary. For example, if you experience side effects at any point during dose escalation, your doctor may delay your next dose increase by several weeks.
The following dosing guide describes dosages that are commonly used or recommended. However, be sure to use the dosage your doctor prescribes for you. Your doctor will determine the best dosage to fit your needs.
Dosage for weight loss and weight management
The dosing chart below shows typical Wegovy doses and the drug’s dose schedule for weight loss and weight management. You’ll inject a Wegovy dose once per week.
|Week of therapy
|Wegovy weekly dose
|weeks 1 through 4 (the first month)
|weeks 5 through 8 (the second month)
|weeks 9 through 12 (the third month)
|weeks 13 through 16 (the fourth month)
|weeks 17 and beyond (maintenance)
|1.7 mg or 2.4 mg
If you have intolerable side effects from a 2.4-mg maintenance dose, your doctor may lower the dose to 1.7 mg. If you still have intolerable side effects with the 1.7-mg maintenance dose, your doctor may have you stop treatment with Wegovy.
The recommended dosage schedule for children ages 12 years and older is the same as that for adults. A child’s doctor will prescribe a dosage at the start of treatment. Then, the doctor will adjust the dosage over time to reach a maximum dose.
Wegovy is meant to be used as a long-term treatment. If you and your doctor determine that Wegovy is safe and effective for you, you’ll likely use it long term.
Treatment with Wegovy isn’t recommended for adults who have intolerable side effects from a 2.4-mg or 1.7-mg dose of the drug.
Below are answers to some frequently asked questions about Wegovy’s dosage.
How will my doctor determine the right Wegovy dose schedule for me?
Typically, doctors will follow the recommended dose schedule for Wegovy. This is described above in the “Wegovy dosage” section. There isn’t an alternative dosing schedule recommended for the drug.
Talk with your doctor if you have questions about Wegovy’s dose schedule.
Why is there a starting dose for Wegovy?
A starting dose and dose escalation schedule for Wegovy are recommended to help lower the risk of certain side effects.
Specifically, slowly increasing Wegovy’s dose over time can help lower your risk of gastrointestinal side effects such as:
- nausea and vomiting
- abdominal pain
- upset stomach
- excessive belching or gas
What to do if you miss a dose of Wegovy depends on when your next scheduled dose is due.
For instance, if you miss a Wegovy dose and your next scheduled dose is due to be injected in:
- more than 48 hours, take the missed dose as soon as possible.
- less than 48 hours, skip the missed dose. Then, take your next dose at the usual time. Do not inject more than one dose of Wegovy at a time.
If it has been 2 or more weeks since your last dose of Wegovy, call your doctor. They may have you:
- resume Wegovy treatment at the usual dose on the next scheduled day, or
- restart Wegovy treatment with the recommended dose escalation schedule. (For details, see the “Wegovy dosage” section above.) Your doctor may recommend this option if you’ve had gastrointestinal side effects due to Wegovy.
