Where to inject Wegovy
Abdomen
The Wegovy Instructions for Use list the abdomen as an injection site. Inject under the skin, not into muscle or a vein. Your pharmacist or prescribing clinician can show you how to choose a spot and rotate sites.
Thigh
The thigh is also listed as an approved injection site in the Instructions for Use. Rotating where you inject can help reduce local skin reactions. Follow the pen Instructions for Use for handling and disposal.
Upper arm
The upper arm is a labeled injection site option. Many people need another person to help with upper arm injections, so ask your clinician or pharmacist what is safest for you. Use only the method described in the Instructions for Use.
How to take Wegovy safely (label basics)
How often to take it
Wegovy is injected under the skin once weekly. The label recommends choosing the same day each week, at any time of day, with or without meals. If you need to change your weekly day, the label describes when that is allowed.
Rotate injection sites
The Instructions for Use recommend rotating injection sites with each injection. Rotating can help lower the chance of irritation or lumps at the injection area. Avoid injecting into skin that is tender, bruised, red, or hard.
Missed dose rules
If you miss a dose, the FDA label gives timing based rules for when to take the missed dose and when to skip it and take your next dose on the regularly scheduled day. Do not take extra doses to make up for a missed one.
Common side effects to plan for
The most common side effects in the prescribing information are gastrointestinal, including nausea, vomiting, diarrhea, abdominal pain, and constipation. Eating smaller meals and avoiding high fat foods may help some people, but talk with your clinician if symptoms are persistent or severe.
Serious risks to know
Wegovy has a boxed warning about risk of thyroid C-cell tumors based on rodent studies, and it should not be used in people with a personal or family history of medullary thyroid carcinoma or MEN 2. Other important warnings include pancreatitis, gallbladder problems, acute kidney injury, increased heart rate, and suicidal behavior or ideation.
Low blood sugar risk
Wegovy can increase the risk of low blood sugar (hypoglycemia) when used with insulin or insulin secretagogues such as sulfonylureas. If you use diabetes medications, your prescriber may adjust your overall plan and monitoring. Do not change diabetes medicines on your own.
When to contact your clinician urgently
Possible pancreatitis
Contact your clinician right away for severe abdominal pain that may radiate to your back, with or without vomiting. The Wegovy label warns about acute pancreatitis and recommends stopping the medication if pancreatitis is suspected until you are evaluated.
Gallbladder symptoms
Seek medical advice promptly for upper right abdominal pain, fever, jaundice, or persistent nausea and vomiting. The prescribing information warns about acute gallbladder disease, including cholelithiasis and cholecystitis.
Allergic reaction
Get emergency care for swelling of the face, lips, tongue, or throat, trouble breathing, or a severe rash. Serious hypersensitivity reactions are listed in the prescribing information. Do not take another dose until you have been evaluated.
Kidney problems or dehydration
Call your clinician if vomiting or diarrhea is severe or does not stop, especially if you cannot keep fluids down. The label warns that dehydration from gastrointestinal side effects can worsen kidney function and has been associated with acute kidney injury.
Mood changes
Tell your clinician promptly about new or worsening depression, suicidal thoughts, or unusual mood changes. The Wegovy label includes a warning about suicidal behavior and ideation. If you feel unsafe, seek emergency help.
