Question 1

Which works better for weight loss, Ozempic or Trulicity?

Accepted Answer

On the trial evidence, Ozempic. Ozempic recorded -6.5 kg (Ozempic 1 mg) and Trulicity -3.0 kg (Trulicity 1.5 mg), and the head-to-head comparison put Ozempic at -1.8% (Ozempic 1 mg) against Trulicity at -1.4% (Trulicity 1.5 mg). A head-to-head is the strongest form of this evidence because both arms run under one protocol — separate trials are not directly comparable however alike they look.

Question 2

Are Ozempic and Trulicity the same drug?

Accepted Answer

No. Ozempic is semaglutide and Trulicity is dulaglutide — different molecules, and they work differently: GLP-1 receptor agonist against GLP-1 receptor agonist. Results with one do not predict results with the other.

Question 3

Is Ozempic or Trulicity cheaper?

Accepted Answer

On the manufacturers' own cash pricing: Ozempic at About $998/mo retail; the savings card needs commercial insurance and a diabetes diagnosis, Trulicity at About $987/mo retail; a $25 savings card, commercial insurance only. ⚠ That is the list-price comparison, and it is not what most people pay. What you actually pay depends on whether your plan covers it, which formulary tier it sits in, and whether you have met your deductible — and for many people the honest comparison is between an insured copay and a cash-pay compounded alternative rather than between these two figures.

Question 4

Does either one have better cardiovascular evidence?

Accepted Answer

Ozempic does. Ozempic: SUSTAIN-6: MACE -26% (HR 0.74, n=3,297, secondary-prevention bent). Trulicity: REWIND: MACE -12% (HR 0.88, n=9,901, primary-prevention majority). This matters more than it first appears — a drug with a completed outcomes trial has evidence about events that matter, not only about weight, and that is often what decides coverage.

Question 5

What does a compounded version of each actually cost?

Accepted Answer

Across the 556 sellers in this register, the cheapest standing monthly cash prices we hold are semaglutide from $79 a month. ⛔ A compounded preparation is not the approved product: no agency has reviewed that specific preparation for safety, effectiveness or manufacturing quality, and the legal ground under compounding these molecules narrowed once the shortages closed. The price gap is real and so is the difference in oversight.

Question 6

Can I switch from Ozempic to Trulicity?

Accepted Answer

Yes, with a prescriber. Expect to re-titrate from the bottom of the new drug's ladder rather than starting where you left off: these are different molecules and tolerance to one does not transfer to the other. Both the old drug's washout and the new drug's schedule apply.

Question 7

Which one should I ask for?

Accepted Answer

That is a prescriber's call, and anyone answering it from a table is guessing. What a page like this can do is tell you what the trials measured, what the manufacturers charge, and where the evidence is still missing, so the conversation starts from the record rather than from an advertisement.
