Which Is Right for You?

The "better" medication depends entirely on your individual medical history, insurance coverage, treatment goals, and tolerability. Here are key decision scenarios:

★ Primary goal is maximum weight loss

Based on clinical trial data, Saxenda has demonstrated higher percentage weight loss in pivotal trials. Discuss whether the magnitude of difference is clinically meaningful for your situation with your prescriber.

★ You have type 2 diabetes as primary concern

Trulicity is FDA-approved for T2D management. Your prescriber will consider HbA1c targets, cardiovascular risk, renal function, and cost when choosing between them.

★ You have established cardiovascular disease

Trulicity has demonstrated cardiovascular outcome benefits in clinical trials. For patients with high CV risk, Trulicity may be preferred when clinically appropriate.

★ You prefer fewer injections

Trulicity requires only once-weekly injection; Saxenda requires daily injection. If injection frequency is a barrier, Trulicity may improve adherence.

★ Cost is a primary factor

Cash prices differ significantly between medications. Saxenda costs approximately $1,300–$1,400/month/month without insurance; Trulicity costs approximately $700–$800/month/month. Both manufacturers offer savings programs for commercially insured patients. Use our Cost Estimator → to compare your specific situation.
