Semaglutide Dosage Chart: Ozempic and Wegovy Escalation Schedule

Quick Answer

Semaglutide starts at 0.25 mg weekly for the first 4 weeks, then escalates every 4 weeks to the target maintenance dose. Wegovy's maximum dose is 2.4 mg weekly (for obesity). Ozempic's maximum approved dose is 2 mg weekly (for diabetes). Both use the same escalation structure; the ceiling differs by indication.

Wegovy Dosage Chart (Obesity)

Weeks	Dose	Notes
Weeks 1–4	0.25 mg	Starting dose — not therapeutic, builds tolerance
Weeks 5–8	0.5 mg	First escalation
Weeks 9–12	1 mg	Second escalation
Weeks 13–16	1.7 mg	Third escalation
Week 17+	2.4 mg	Maximum maintenance dose

Injection frequency: Once weekly, same day each week. Time of day and food intake don't significantly affect absorption.

Target dose: 2.4 mg is the FDA-approved maintenance dose for obesity (Wegovy). This is the dose used in the STEP clinical trials showing 15–17% average body weight loss.

Ozempic Dosage Chart (Type 2 Diabetes)

Weeks	Dose	Notes
Weeks 1–4	0.25 mg	Starting dose — not therapeutic
Weeks 5–8	0.5 mg	First therapeutic dose
Week 9+	1 mg	Standard maintenance dose
(If needed)	2 mg	Maximum approved dose for Ozempic

Key difference from Wegovy: Ozempic's maximum approved dose is 2 mg, vs. 2.4 mg for Wegovy. Both contain semaglutide — the active ingredient is identical. The approved dose ceiling differs by indication.

Can You Slow the Escalation?

Yes, and for many patients this is advisable. The 4-week escalation schedule is a guideline. Common modifications:

Extended escalation: Staying at each dose for 8 weeks instead of 4 is a frequently used approach, particularly for patients experiencing significant nausea. GI tolerance improves markedly with time at a stable dose.

Stopping at an intermediate dose: Many patients achieve their goals at 1.0 or 1.7 mg and elect to stay there. There is no clinical obligation to reach 2.4 mg — the maximum dose produces the greatest average weight loss but also the highest rate of side effects.

Stepping down: If a dose increase causes intolerable side effects, stepping back to the previous dose for 4–8 weeks before retrying is medically appropriate.

Dose Timing and Administration

Day and time: Pick a consistent weekly day. Many patients choose Sunday (easy to remember). Time of day is flexible — morning, evening, or with meals all produce equivalent outcomes.

Injection site options: Abdomen (most common), outer thigh, or upper arm. Rotate sites weekly to reduce injection site reactions.

Storage: Refrigerated (36–46°F) before first use. After first use, the pen can be stored at room temperature (up to 77°F) for up to 56 days or refrigerated.

Pen availability for Wegovy: 0.25 mg/0.5 mg, 1 mg, 1.7 mg, and 2.4 mg pens are separate products. Your prescription should specify the dose; the pharmacy dispenses the corresponding pen.

Missed Dose Protocol

Missed by 5 days or fewer: Take the missed dose as soon as possible. Then resume your regular weekly schedule.

Missed by more than 5 days: Skip the missed dose. Resume your next scheduled dose on the regular day.

Never double-dose. Taking two doses in one week to compensate significantly increases nausea, vomiting, and GI discomfort.

If you miss more than 2 consecutive weeks, contact your prescriber. Re-escalating from a lower dose may be appropriate, as tolerance decreases with prolonged absence.

Semaglutide for Weight Loss: Off-Label Ozempic Dosing

Some patients receive Ozempic prescribed off-label for weight loss rather than Wegovy. When used for obesity, some prescribers titrate to doses above the 2 mg Ozempic ceiling — effectively prescribing at Wegovy dosing levels.

This is a prescriber decision based on clinical judgment. The active ingredient is identical; the approved maximum dose differs by product. Patients using Ozempic for weight loss off-label should discuss dosing targets specifically with their prescriber.

Semaglutide Injection: What to Expect

For new injectors, the semaglutide auto-injector pens are designed for patient self-administration:

Allow pen to reach room temperature (30 minutes out of refrigerator reduces injection discomfort)
Attach a new needle
Dial to your prescribed dose
Pinch skin at injection site
Insert needle at 90° angle, press plunger, hold 6 seconds
Remove needle, dispose in sharps container

The needles are 4mm, 32-gauge — very fine. Most patients describe the injection as virtually painless after the first few times.

Bottom Line

Semaglutide's dose escalation from 0.25 mg to 2.4 mg (Wegovy) or 2 mg (Ozempic) takes 16–20 weeks on the standard schedule. The starting dose is intentionally sub-therapeutic — it builds tolerance, not efficacy. Most weight loss begins at 0.5–1 mg and continues increasing at higher doses. Slowing the escalation is almost always better than rushing it; GI side effects are dose-escalation-dependent.
