Wegovy, a medication that has recently gained attention for its effectiveness in weight management, is a formulation of semaglutide—a GLP-1 receptor agonist. Originally developed to treat Type 2 diabetes, people now use semaglutide under the brand name Wegovy to manage chronic weight issues. This article aims to provide a comprehensive and easy-to-understand guide about Wegovy, including its uses, mechanism of action, side effects, and other critical information that patients need to know.
What is Wegovy?
Adults with a body mass index (BMI) of 30 kg/m2 or higher (classified as obesity) or 27 kg/m2 or higher (classified as overweight) and at least one weight-related health condition, such as high blood pressure, Type 2 diabetes, or high cholesterol, can use Wegovy, a prescription medication, for chronic weight management. It’s also prescribed for adolescents aged 12 to less than 18 years who have obesity, as diagnosed by a doctor, and who have not succeeded in losing weight with diet and exercise alone.
How Does Wegovy Work?
Wegovy mimics the release of the natural hormone glucagon-like peptide-1 (GLP-1) after eating. This hormone aids in appetite regulation by making you feel fuller and less hungry. By activating the GLP-1 receptors, Wegovy slows gastric emptying, reduces food intake, and enhances the body’s insulin response. This combination of effects leads to weight loss over time when used alongside a reduced-calorie diet and increased physical activity.
Ingredients and Dosage Forms
Wegovy’s active ingredient is semaglutide. The medication comes in a clear, colourless solution delivered via a pre-filled, single-use pen for subcutaneous injection. Wegovy is available in several dose strengths: 0.25 mg, 0.5 mg, 1 mg, 1.7 mg, and 2.4 mg. Typically, the treatment starts at a lower dose and gradually increases over 16 weeks to minimise side effects and improve patient tolerance.
Who Should Not Use Wegovy?
There are certain conditions under which Wegovy should not be used:
- Medullary Thyroid Carcinoma (MTC): If you or a family member has had MTC or if you have Multiple Endocrine Neoplasia Syndrome type 2 (MEN 2), Wegovy should be avoided due to the potential risk of thyroid tumours.
- Pregnancy and Breastfeeding: It is not advisable to use Wegovy during pregnancy or breastfeeding due to the uncertainty surrounding its potential harm to the unborn child or its potential to enter breast milk.
- Allergic reactions: Do not use Wegovy if you are allergic to semaglutide or any of its ingredients.
Before Starting Wegovy
Before beginning treatment with Wegovy, it’s important to discuss your complete medical history with your healthcare provider. Certain conditions necessitate special attention:
- History of pancreatitis
- Liver or kidney disease.
- Diabetic retinopathy refers to eye problems caused by diabetes.
- Gallbladder disease
- A history of suicidal thoughts or depression is present.
How to Use Wegovy
You administer Wegovy once a week via a subcutaneous injection. The injection sites include the front of your thighs, the front of your waist (abdomen), or your upper arm. It’s important to use the medication exactly as prescribed by your healthcare provider.
The typical dosing schedule for adults starts at 0.25 mg per week and increases gradually over 16 weeks to the maintenance dose of 2.4 mg per week. This gradual increase helps to minimize side effects such as nausea and vomiting. The same dosing schedule applies to adolescents, but if they cannot tolerate the full dose, they may continue on a lower dose.
What to do if you miss a dose
If you forget to take your weekly dose of Wegovy, the timing of your next dose depends on how long it’s been since the missed dose. If it’s been less than five days, take the missed dose as soon as you remember and continue with your regular schedule. If more than five days have passed, skip the missed dose and resume your normal schedule with the next dose. Never double-dose to make up a missed dose.
Possible Side Effects
Like all medications, Wegovy can cause side effects. The following are some of the most common side effects of Wegovy:
- Nausea and vomiting: These are the most frequently reported side effects, particularly when starting treatment or increasing the dose.
- Diarrhoea and Constipation: Gastrointestinal issues are common but typically subside as your body adjusts to the medication.
- Headache and Fatigue: Some patients experience headaches or feel unusually worn out when starting Wegovy.
- Low Blood Sugar (Hypoglycemia): Particularly in patients who are also taking other diabetes medications, low blood sugar can be a concern. Symptoms include sweating, shaking, and dizziness.
Serious side effects, though rare, include:
- Pancreatitis: Severe abdominal pain that radiates to your back may indicate inflammation of the pancreas.
- Gallstones: Sudden upper abdominal pain, frequently on the right side, may accompany symptoms such as nausea and vomiting.
- Thyroid Tumours: Although primarily observed in animal studies, the potential risk of thyroid tumours, including cancer, is a concern, especially for those with a family history of thyroid issues.
Drug Interactions
Wegovy can interact with other medications, potentially altering their effectiveness or increasing the risk of adverse effects. It’s important to inform your healthcare provider of all the medications you’re taking, including over-the-counter drugs, vitamins, and supplements. Some of the known interactions include:
- Medications for Hypertension or Heart Failure: These may increase your heart rate when combined with Wegovy.
- Insulin and Sulfonylureas: These diabetes medications, when taken with Wegovy, can increase the risk of hypoglycemia.
- Appetite Suppressants: Combining these with Wegovy may result in excessive weight loss and other complications.
Storing Wegovy
Proper storage of Wegovy is essential to maintaining its effectiveness. Store the single-use pens in the refrigerator between 2°C and 8°C (36°F to 46°F) until you use them. Avoid freezing them or exposing them to temperatures exceeding 30°C (86°F). You can store a pen at room temperature for up to 28 days before discarding it once you remove it from the refrigerator.
After use, dispose of the pen safely in a sharps container. Never throw used needles or pens in household trash to avoid injury to others.
Wegovy and Lifestyle Changes
Wegovy is most effective when used as part of a comprehensive weight management plan that includes a reduced-calorie diet and increased physical activity. Your healthcare provider will likely recommend a meal plan and exercise routine tailored to your needs.
Pregnancy and Wegovy
Women of childbearing age should use effective contraception while on Wegovy. If you become pregnant while taking Wegovy, inform your healthcare provider immediately. Discontinue Wegovy at least two months before a planned pregnancy to prevent potential risks to the unborn child.
Who Can Benefit from Wegovy?
Individuals struggling with obesity or weight-related health conditions, who have not found success with diet and exercise alone, are the target audience for Wegovy. It’s particularly beneficial for those at risk of developing or already managing Type 2 diabetes, high blood pressure, or high cholesterol.
However, WeGovy is not for everyone. Patients with a history of certain medical conditions, such as thyroid cancer or pancreatitis, should avoid using this medication. Additionally, those who are pregnant, breastfeeding, or planning to become pregnant should discuss alternative weight management options with their healthcare provider.
Monitoring and Follow-Up
Regular monitoring is crucial for patients on Wegovy. Your healthcare provider will likely schedule follow-up visits to assess your progress, adjust your dose if necessary, and monitor for any side effects. It’s also important to regularly check your blood sugar levels, especially if you are also taking other diabetes medications.
Patients should report any new or worsening symptoms, particularly those related to thyroid or pancreatic health, to their healthcare provider immediately.
Wegovy and Long-Term Weight Management
Although wegovy can be a valuable tool for achieving and maintaining weight loss, it is important to view it as one component of a broader, long-term weight management strategy. Lifestyle changes, including a healthy diet and regular physical activity, are essential for sustaining weight loss and improving overall health.
Patients who stop taking Wegovy may regain weight if they do not continue with their dietary and exercise routines. Therefore, we recommend ongoing support from healthcare providers, nutritionists, and fitness professionals to help patients stay on track.
Conclusion
Wegovy offers a promising option for individuals struggling with obesity and related health conditions. Its ability to help patients feel fuller, reduce food intake, and promote weight loss makes it a powerful tool in the fight against obesity. However, Wegovy, like all medications, carries potential risks and side effects that require careful management in consultation with a healthcare provider.
By combining Wegovy with a comprehensive weight management plan that includes diet, exercise, and regular medical monitoring, patients can achieve meaningful and lasting weight loss. As with any treatment, patient education and adherence to prescribed regimens are key to success.
Wegovy represents an exciting advancement in weight management therapy, offering hope to many who have struggled to achieve their weight loss goals through traditional methods alone.
