Understanding your insulin syringe

Measuring your dose
Insulin syringes are used for subcutaneous injections. They are marked in Units on the insulin syringe barrel (see illustration). Insulin syringes facilitate the precise measurement of tiny amounts of liquids which are ideal for medications such as insulin that require small and accurate dosing. Unit marks are also expressed in mL’s and can be interchangeably referenced. A prescriber may write a prescription in Units or in mL’s.
Within the amount of liquid is the prescribed mg dosage of your medication (see mg chart). Milligrams (mg) is not an amount of liquid, but rather the amount of drug that is within. The conversion between units and milligrams varies depending on the concentration of the product being used.

Indications
WEGOVY® is a prescription GLP-1 receptor agonist used:
- As an adjunct to a reduced-calorie diet and increased physical activity for chronic weight management in:
- Adults with obesity (BMI ≥30), or
- Adults with overweight (BMI ≥27) with at least one weight-related comorbidity.
- Pediatric patients aged 12 years and older with obesity.
- To reduce the risk of major cardiovascular events (cardiovascular death, non-fatal heart attack, or non-fatal stroke) in adults with established cardiovascular disease and either obesity or overweight.
BLACK BOX WARNING: Risk of Thyroid C-Cell Tumors
In rodent studies, semaglutide caused thyroid C-cell tumors, including medullary thyroid carcinoma (MTC). It is unknown whether this risk applies to humans.
Do not use WEGOVY® if you:
- Have a personal or family history of MTC or Multiple Endocrine Neoplasia syndrome type 2 (MEN 2).
- Are pregnant, breastfeeding, or planning to become pregnant or breastfeed without medical guidance.
Contraindications

- Have a personal or family history of MTC or MEN 2.
- Are pregnant or planning to become pregnant.
- Have Type 1 diabetes.
- Have a history of pancreatitis.
- Have severe gastrointestinal disease (e.g., gastroparesis).
- Have known hypersensitivity to semaglutide, other GLP-1 receptor agonists, or any inactive ingredients in WEGOVY® (including di-sodium phosphate dihydrate, sodium chloride, water for injection, hydrochloric acid, or sodium hydroxide).
- Have a history of suicidal ideation or behavior.
Warnings and Precautions
- Pancreatitis: Has occurred in trials. Discontinue immediately if suspected. Do not restart if confirmed.
- Gallbladder Disease: Monitor for signs of gallstones or cholecystitis.

Drug Interactions and Limitations of Use
- WEGOVY® delays gastric emptying, which may affect the absorption of oral medications. Use caution when co-administering oral drugs that require rapid absorption.
- Co-administration with other semaglutide-containing products or GLP-1 receptor agonists is not recommended.
- The safety and effectiveness of combining WEGOVY® with other weight-loss medications have not been established.
- Clinical experience in patients with a history of pancreatitis is limited; it is unknown if these patients are at increased risk.
Reproductive Considerations
- Pregnancy: May cause fetal harm. Discontinue WEGOVY® immediately if pregnancy is detected.
- Reproductive Planning: Stop WEGOVY® at least 2 months prior to a planned pregnancy due to its long half-life.

Frequently Asked Questions
What are the side effects of Wegovy?
Potential side-effects can vary between individuals, based on medical history and lifestyle factors. The most common side effects are gastrointestinal: nausea, vomiting, diarrhea, and constipation. These often occur during dose titration and typically decrease over time. Rare but serious risks include pancreatitis and gallbladder issues.
Is Wegovy the same as Ozempic?
Wegovy and Ozempic contain the same active ingredient (semaglutide), but they are approved for different uses and come in different dosing ranges. Wegovy is FDA-approved for weight loss, while Ozempic is indicated for type 2 diabetes but is often used off-label for weight management.
How do I store Wegovy pens?
Store in the refrigerator between 36–46°F. Once in use, the pen may be stored at room temperature (up to 86°F) for up to 28 days.
