Wegovy is prescribed as a once-weekly injection for long-term weight management, and getting it involves meeting specific weight criteria, completing baseline blood work, and following a gradual dose increase over about four months. Any licensed healthcare provider can prescribe it, from a primary care doctor to an endocrinologist or obesity medicine specialist.
Who Qualifies for a Prescription
The FDA approved Wegovy for two groups of adults: those with obesity (a BMI of 30 or higher) and those with overweight (a BMI of 27 to 29.9) who also have at least one weight-related health condition. Common qualifying conditions include type 2 diabetes, high blood pressure, high cholesterol, and obstructive sleep apnea.
Adolescents aged 12 and older can also be prescribed Wegovy, but the threshold is different. They need a BMI at or above the 95th percentile for their age and sex, which is the clinical definition of obesity in children and teens.
One absolute rule: Wegovy cannot be prescribed to anyone with a personal or family history of medullary thyroid carcinoma or a condition called Multiple Endocrine Neoplasia syndrome type 2 (MEN 2). These are rare but serious contraindications that your provider will ask about before writing a prescription.
What Happens Before You Get a Prescription
Before starting Wegovy, your provider will typically order a panel of baseline blood tests. These serve two purposes: screening for conditions that could make the medication unsafe, and establishing a starting point so your health can be tracked over time.
The standard workup includes blood sugar markers (like HbA1c and fasting glucose), liver function tests, kidney function tests, thyroid levels, and a lipid panel covering cholesterol and triglycerides. Kidney function matters because patients with significantly reduced kidney performance need closer monitoring. Thyroid screening is a standard precaution given the medication’s contraindication in certain thyroid cancers. Your provider may also check inflammation markers, a full blood count, and nutritional levels like vitamin D and iron, since rapid weight loss can affect nutrient absorption down the line.
You’ll also have your BMI calculated from your height and weight, and your provider will review your medical history for any past episodes of pancreatitis, gallbladder disease, or mental health concerns like depression or suicidal thoughts, all of which require extra caution with this class of medication.
The Dose Escalation Schedule
Wegovy is not prescribed at full strength from day one. Instead, you follow a 16-week ramp-up designed to let your body adjust and reduce side effects, especially nausea and other gastrointestinal symptoms.
The schedule works like this:
- Weeks 1 through 4: 0.25 mg once weekly
- Weeks 5 through 8: 0.5 mg once weekly
- Weeks 9 through 12: 1 mg once weekly
- Weeks 13 through 16: 1.7 mg once weekly
- Week 17 onward: maintenance dose
Each step lasts exactly four weeks before moving up. The early doses are too low to produce significant weight loss on their own. Their purpose is purely to help your digestive system adapt to the medication gradually. Skipping steps or increasing too quickly tends to make nausea, vomiting, and diarrhea much worse.
Maintenance Dose Options
Once you reach week 17, adults have two possible maintenance doses: 2.4 mg per week (the recommended target) or 1.7 mg per week. Your provider may keep you at 1.7 mg if you’re responding well at that level or if side effects at the higher dose are too difficult to manage. For adolescents aged 12 and older, the maintenance dose is 2.4 mg with no lower option specified in the prescribing guidelines.
Wegovy is intended as a long-term medication. Clinical trials that supported its approval ran for 68 weeks, and the prescribing label describes it as a treatment for maintaining weight reduction over time. If you stop taking it, weight regain is common, which is why prescribers generally plan for ongoing use rather than a fixed course.
How You Take the Injection
You inject Wegovy once per week, on the same day each week, at whatever time of day is convenient. It doesn’t need to be taken with food. The injection goes just under the skin (subcutaneously) in one of three sites: your abdomen, thigh, or upper arm. Most people rotate between these areas to avoid irritation at a single spot.
The medication comes in a prefilled, single-use pen with a hidden needle, so you don’t see the needle before or during the injection. Each dose level has its own pen, color-coded to prevent mix-ups during the escalation period. Your provider or pharmacist will walk you through the first injection, but after that, most people self-administer at home without difficulty.
Who Can Prescribe It
No specialist referral is required. The FDA labeling refers only to “healthcare provider” without restricting prescribing to any particular specialty. In practice, primary care physicians write the majority of Wegovy prescriptions. Endocrinologists, obesity medicine specialists, and in some cases nurse practitioners and physician assistants with prescribing authority can also write the prescription.
Telehealth providers have become another common route. Several online platforms now offer Wegovy prescriptions after a virtual consultation and review of lab results, though insurance coverage and medication availability can vary significantly depending on the provider and your plan. If your insurance requires prior authorization, your prescriber’s office typically handles the paperwork, which may include documenting your BMI, previous weight-loss attempts, and qualifying health conditions.
Insurance and Access Considerations
Getting a prescription is only part of the process. Many insurance plans require prior authorization before they’ll cover Wegovy, meaning your provider needs to submit documentation proving you meet the criteria. Some plans exclude weight-management medications entirely, and others require evidence that you’ve tried diet, exercise, or other interventions first.
Without insurance, Wegovy’s list price is significant enough that most people need some form of coverage or savings program to afford it long-term. Novo Nordisk, the manufacturer, offers a savings card for commercially insured patients, though eligibility rules and copay amounts change periodically. If your first prior authorization is denied, your provider can often appeal with additional clinical documentation.
