Trulicity vs Ozempic
Dulaglutide vs Semaglutide — Weekly GLP-1 Comparison (2026)
Trulicity (dulaglutide) and Ozempic (semaglutide) are both once-weekly GLP-1 injections for type 2 diabetes. They were compared directly in the SUSTAIN-7 trial. Here's how they differ on blood sugar, weight, dosing, and tolerability.
Trulicity vs Ozempic: At a Glance
- ✓GLP-1 receptor agonist
- ✓Once-weekly subcutaneous injection
- ✓FDA-approved for type 2 diabetes
- ✓Simple auto-injector, no dose titration of the pen needed
- ✓Effective HbA1c reduction; modest weight loss
- ✓Eli Lilly
- ✓GLP-1 receptor agonist
- ✓Once-weekly subcutaneous injection
- ✓FDA-approved for type 2 diabetes
- ✓SUSTAIN-7: superior to dulaglutide on HbA1c and weight
- ✓Greater weight loss than Trulicity
- ✓Novo Nordisk

How to Choose
Stronger Glucose & Weight
In the SUSTAIN-7 head-to-head, semaglutide (Ozempic) beat dulaglutide (Trulicity) on both HbA1c reduction and weight loss.
Easiest Injection
Trulicity's auto-injector hides the needle and requires no priming or dialing — often preferred by needle-averse patients.
Cardiovascular Data
Both have CV outcome trials in diabetes (REWIND for dulaglutide, SUSTAIN-6 for semaglutide). Either supports heart-risk reduction.
Weight Goal
If weight loss matters, semaglutide has the edge — and Wegovy (its obesity brand) goes further than either diabetes dose.
Tolerability
Both cause GI side effects; some patients tolerate dulaglutide's gentler curve better. Individual response varies.
Cost & Coverage
Formulary placement and savings cards often decide the real-world choice between these two diabetes GLP-1s.
Which Should You Choose?
On efficacy, the head-to-head SUSTAIN-7 trial gives semaglutide (Ozempic) the advantage: it produced greater HbA1c reduction and more weight loss than dulaglutide (Trulicity). If maximizing glucose control or weight loss is the priority, Ozempic is the stronger of the two.
Trulicity's appeal is simplicity and tolerability. Its auto-injector hides the needle and needs no dialing, which many patients prefer, and some tolerate dulaglutide's side-effect profile a little better. Both have proven cardiovascular benefit in diabetes.
If weight loss is a major goal, note that neither diabetes drug is the strongest tool — semaglutide's obesity brand (Wegovy) goes further. Whatever you take, track your dose, weight, glucose, and side effects in Shotlee.
Trulicity vs Ozempic: Frequently Asked Questions
In the head-to-head SUSTAIN-7 trial, Ozempic (semaglutide) was superior to Trulicity (dulaglutide) on both HbA1c reduction and weight loss. Trulicity's advantages are its easy hidden-needle auto-injector and tolerability for some patients.
Both are once-weekly GLP-1 injections for type 2 diabetes. Trulicity is dulaglutide (Eli Lilly); Ozempic is semaglutide (Novo Nordisk). Semaglutide tends to lower glucose and weight more.
Ozempic (semaglutide) produces more weight loss than Trulicity (dulaglutide). For weight loss specifically, semaglutide's obesity brand Wegovy goes further than either diabetes dose.
Many patients find Trulicity easier — its auto-injector hides the needle and needs no priming or dose dialing. Ozempic uses a pen with a dose dial.
Yes. Shotlee tracks any GLP-1 — dulaglutide and semaglutide included — with dose logs, weight, glucose, and side-effect tracking.
