Wegovy dosage: Dosage, Schedule, Storage & Important Safety Tips

Last updated: October 30, 2026

A single Wegovy pen that sits too long on a kitchen counter or gets frozen overnight in a cooler can become unusable in days. Getting Wegovy dosage, schedule, storage, and safety right is not a minor detail, it’s the difference between steady progress and a wasted prescription. This guide walks through exactly how Wegovy dosing works, what the weekly schedule looks like, how to store the pens correctly, and the safety issues every patient should understand before their first injection.

Quick Answer

Wegovy (semaglutide) dosing starts at 0.25 mg once weekly and increases every four weeks through 0.5 mg, 1 mg, and 1.7 mg before reaching the standard maintenance dose of 2.4 mg once weekly at week 17 [Source: FDA label, 2026]. Pens must stay refrigerated at 36-46°F until use, can sit at room temperature for up to 28 days once started, and must never be frozen [Source: FDA label, 2026][Source: Novo Nordisk, 2026].

Key Takeaways

• Wegovy follows a five-step titration schedule over 16 weeks before reaching the full 2.4 mg maintenance dose [Source: FDA label, 2026].
• Injections happen once weekly, same day each week, with or without food [Source: Wegovy FAQ, 2026].
• Pens need refrigeration at 2-8°C (36-46°F) and must never freeze [Source: DailyMed, 2024-2026].
• Once removed from the fridge, pens are good at room temperature for up to 28 days, then must be discarded [Source: Novo Nordisk, 2026].
• Patients unable to tolerate 2.4 mg may stay on 1.7 mg as an alternative maintenance dose [Source: FDA label, 2025].
• Wegovy carries a boxed warning for thyroid C-cell tumor risk and is contraindicated with a personal or family history of MTC or MEN2 [Source: FDA label, 2023].
• Common side effects (nausea, vomiting, diarrhea) tend to peak during dose increases, which is why the slow titration matters [Source: Wegovy Patient Brochure, 2026].

What’s the Starting Dose of Wegovy

The starting dose of Wegovy is 0.25 mg injected once weekly for the first four weeks. This dose is not meant for weight loss itself, it’s an introductory step that lets your body adjust to semaglutide before the dose climbs higher [Source: Wegovy Patient Brochure, 2026].

Doctors prescribe this low starting point because jumping straight to a higher dose dramatically raises the risk of nausea, vomiting, and stomach upset. Think of it as priming the system. If you’re also comparing doses across semaglutide products, our semaglutide dosage chart for weight loss breaks down the mg and unit equivalents side by side.

Common mistake: Some patients assume a higher starting dose will produce faster results. It won’t, and it significantly increases the odds of severe gastrointestinal side effects that can cause people to quit treatment altogether.

Wegovy Dosage Schedule Week by Week

Wegovy’s dosage schedule moves through five distinct levels over roughly four months, increasing every four weeks until reaching the maintenance dose. This gradual approach is written directly into the FDA prescribing information and patient brochure [Source: FDA label, 2026][Source: Wegovy Patient Brochure, 2026].

Weeks	Dose	Purpose
1-4	0.25 mg	Starting dose, builds tolerance
5-8	0.5 mg	First increase
9-12	1 mg	Mid-level increase
13-16	1.7 mg	Pre-maintenance step
17+	2.4 mg	Full maintenance dose

Choose to stay on a lower step longer only if your prescriber recommends it, typically because of side effects. Never self-adjust the timeline. Full details on the pen mechanics are covered in our guide to the Wegovy weekly injection pen.

What’s the Maximum Dose of Wegovy

The maximum approved dose of Wegovy is 2.4 mg once weekly, reached at week 17 and continued for long-term weight management. There is no higher dose beyond 2.4 mg currently approved [Source: FDA label, 2025].

If 2.4 mg causes side effects that are hard to manage, the FDA prescribing information allows a step down to 1.7 mg once weekly as an alternative maintenance dose rather than stopping treatment entirely [Source: FDA label, 2025][Source: FDA label, 2026]. This is a decision your prescriber makes based on how you’re tolerating treatment, not something to adjust on your own.

Edge case: Patients who switch from Ozempic to Wegovy sometimes assume their Ozempic dose translates directly. It doesn’t always, since the two products have different approved maximum doses and indications, covered more in the next section.

What’s the Difference Between Wegovy and Ozempic

Wegovy and Ozempic both contain semaglutide, but they’re approved for different purposes and carry different maximum doses. Wegovy is approved for chronic weight management and tops out at 2.4 mg weekly, while Ozempic is approved for type 2 diabetes management and has its own dosing range.

The titration logic is similar, slow increases every four weeks, but the indications, insurance coverage pathways, and some dosing details differ. If you’re deciding between them or want patient feedback, our Wegovy reviews roundup covers real-world experiences with the medication.

Decision rule: Choose Wegovy if your primary goal is chronic weight management and you meet BMI or comorbidity criteria. Choose Ozempic only if a doctor is managing type 2 diabetes, not weight loss alone, since that’s its approved indication.

How Do I Store Wegovy Pens

Wegovy pens must be refrigerated at 36-46°F (2-8°C) in their original carton, protected from light, and never frozen. A frozen pen is a ruined pen and should be thrown away immediately [Source: DailyMed, 2024-2026][Source: Novo Nordisk, 2026].

Once you take a pen out of the fridge to start using it, here’s how the room-temperature rules work:

• Pens can be kept at 46-86°F (8-30°C) for up to 28 days after removal from the fridge [Source: Novo Nordisk, 2026][Source: DailyMed, 2024-2026].
• After 28 days at room temperature, discard the pen even if it looks fine.
• Exposure above 86°F or direct bright light also means the pen must be discarded early.
• Avoid storing pens directly against the refrigerator’s cooling element, which can accidentally freeze them [Source: Novo Nordisk, 2026].
• Keep the cap on while the pen sits at room temperature [Source: Wegovy Quick Start Guide, 2026].

Common mistake: Packing a pen in a cooler with ice packs for travel. Direct contact with ice can freeze the solution. If you’re traveling, our guide on Ozempic refrigeration and travel rules walks through safer transport methods that apply to semaglutide pens generally.

What Happens If I Miss a Wegovy Injection

If you miss a Wegovy injection, take it as soon as possible if you’re within 5 days of the missed dose. If more than 5 days have passed, skip that dose and resume your regular schedule on the next scheduled day [Source: Wegovy FAQ, 2026].

Do not double up doses to make up for a missed one. If you miss multiple consecutive doses, especially more than 2 weeks, your prescriber may need to restart you at a lower dose to avoid side effects, since your tolerance may have changed [Source: FDA label, 2026].

Quick example: You normally inject every Monday. You forget and remember on Thursday, that’s within the 5-day window, so you inject Thursday and go back to Monday injections the following week.

Is Wegovy Safe If I Have Diabetes

Wegovy can be used by people with type 2 diabetes, but it requires monitoring because semaglutide affects blood sugar and can increase the risk of diabetic retinopathy complications in some patients. This is noted directly in the FDA label’s warnings and precautions section [Source: FDA label, 2026].

Patients with diabetes on insulin or sulfonylureas need closer glucose monitoring when starting Wegovy, since the combination can raise hypoglycemia risk. Discuss current diabetes medications with your prescriber before starting, since dose adjustments to other drugs may be necessary [Source: FDA label, 2025].

Decision rule: If you have diabetic retinopathy history, tell your prescriber before starting, they may want more frequent eye monitoring during treatment [Source: FDA label, 2026].

What Are the Side Effects of Wegovy

The most common Wegovy side effects are nausea, vomiting, diarrhea, constipation, abdominal pain, headache, fatigue, and injection-site reactions, most noticeable during dose increases [Source: FDA label, 2023][Source: Wegovy Patient Brochure, 2026].

Serious but less common risks include:

• Pancreatitis: severe abdominal pain that doesn’t go away, sometimes with vomiting.
• Gallbladder problems: pain in the upper right abdomen, fever, or yellowing skin.
• Kidney injury: often tied to dehydration from vomiting or diarrhea.
• Thyroid tumors: a boxed warning risk, covered in detail below.

If you’re experiencing persistent diarrhea or constipation, our article on Ozempic diarrhea and constipation causes and relief tips offers practical relief strategies that apply to semaglutide-based medications broadly.

Common mistake: Pushing through severe abdominal pain instead of calling a doctor. Pancreatitis symptoms need prompt medical evaluation, not a wait-and-see approach.

How Long Does It Take to See Results From Wegovy

Most patients don’t see significant weight loss until they reach the higher dose tiers, typically around month 3 or 4 once the dose climbs past 1 mg. Meaningful results generally build over the full titration period and beyond, since the medication works gradually as the dose increases [Source: Wegovy Patient Brochure, 2026].

Results vary widely by individual, diet, and activity level. Wegovy is approved as an adjunct to a reduced-calorie diet and increased physical activity, not a standalone solution [Source: FDA label, 2026]. Patients who pair the medication with consistent lifestyle changes tend to see more sustained progress than those relying on the injection alone.

Can I Take Wegovy While Pregnant

Wegovy is not recommended during pregnancy. Animal studies and the drug’s mechanism raise concerns about fetal risk, and the FDA label advises discontinuing Wegovy at least 2 months before a planned pregnancy [Source: FDA label, 2026].

If you become pregnant while on Wegovy, contact your healthcare provider immediately to discuss stopping the medication and switching to a pregnancy-appropriate weight management plan. Breastfeeding considerations should also be discussed directly with your prescriber, since data on use during lactation is limited.

What Are Alternatives to Wegovy for Weight Loss

Alternatives to Wegovy include other GLP-1 or dual-agonist medications such as Zepbound (tirzepatide), Saxenda (liraglutide), and compounded semaglutide through telehealth providers, each with different dosing schedules and cost structures.

• Zepbound: a dual GIP/GLP-1 agonist, different mechanism, separate FDA approval for weight management.
• Saxenda: daily injection rather than weekly, older GLP-1 option.
• Compounded semaglutide: available through some telehealth providers, less regulated, variable quality [VERIFY: current legal status varies by state and shortage conditions].
• Lifestyle-only programs: structured diet and exercise coaching without medication.

Decision rule: Choose Wegovy if you meet the BMI/comorbidity criteria and want an FDA-approved, well-studied once-weekly option. Consider alternatives if cost, side effect tolerance, or dosing frequency preferences point you elsewhere, always with medical guidance.

Do I Need a Prescription for Wegovy

Yes, Wegovy requires a prescription from a licensed healthcare provider. It is not available over the counter, and legitimate access requires a medical evaluation to confirm you meet the BMI and health criteria for chronic weight management [Source: FDA label, 2026].

Telehealth providers can prescribe Wegovy after an online consultation in many cases, but be cautious of websites selling the medication without any medical evaluation, since that’s a red flag for counterfeit or unsafe products.

How Much Does Wegovy Cost

Wegovy’s list price and out-of-pocket cost vary significantly by insurance coverage, manufacturer savings programs, and pharmacy [VERIFY: current pricing, as list prices and savings card terms change frequently]. Many patients with commercial insurance that covers weight management medications pay far less than the list price, while uninsured patients often face the full cost.

Check your specific plan’s formulary and ask your prescriber’s office about current manufacturer savings card eligibility, since terms and income qualifications shift over time [VERIFY: savings card terms as of 2026].

Common Mistakes People Make With Wegovy Injections

The most frequent Wegovy injection mistakes involve skipping the titration schedule, injecting in the same spot repeatedly, and mishandling pen storage. Each of these mistakes increases side effects or reduces the medication’s effectiveness.

Checklist to avoid common errors:

1. Rotate injection sites between the abdomen, thigh, and upper arm each week.
2. Check the pen’s liquid is clear and colorless before injecting; discard if cloudy or discolored.
3. Never skip ahead in the dosing schedule to “speed up” results.
4. Keep pens refrigerated until the 28-day room-temperature clock starts.
5. Set a weekly reminder so injections happen on the same day consistently.
6. Don’t share pens, even with a new needle, due to contamination risk.
