Does Trulicity make you throw up?
Yes, and it is on the label rather than only in reports: vomiting appears among the common adverse reactions in Trulicity's FDA prescribing information, published 2026-08-10. Listed means it was seen often enough in the trials to be printed, not that it happens to everyone. Vomiting is nausea that went further, and it comes from the same slowed stomach emptying. It is the single most common reason people stop these drugs early. It clusters in the days after each dose increase. Trulicity's starting dose is already a maintenance dose, so any step up after it is optional. Most people see a few rough days after each step and a settling in between, not one long stretch. Once you are at 0.75 mg to 4.5 mg once weekly and no longer stepping up, the trigger stops recurring. What helps first: treating it as the escalation of nausea: smaller meals, less fat, slower eating. It stops being ordinary at a specific line: vomiting that stops you keeping fluids down, or lasts more than a day. Prolonged vomiting is the mechanism behind the acute kidney injury on these labels. Separately, tell any anesthesiologist you are on this drug: it slows stomach emptying, and food has been found in the stomach despite normal fasting before a procedure — the reason pulmonary aspiration is on these labels.
How long does Trulicity vomiting last?
One injection a week, at any time of day, with or without food. Each row is a step up, and the days after each one are when this tends to arrive.
| Weeks | Dose |
|---|---|
| 1–4 | 0.75 mg |
| 5 and on | 1.5 mg |
| 9 at the earliest | 3 mg |
| 13 at the earliest | 4.5 mg |

Approved for type 2 diabetes rather than for weight. Its label reports the reactions above at 5% or more in the diabetes trials, not in a weight-loss population.
When is vomiting on Trulicity serious?
Vomiting that stops you keeping fluids down, or lasts more than a day. Prolonged vomiting is the mechanism behind the acute kidney injury on these labels. Separately, tell any anesthesiologist you are on this drug: it slows stomach emptying, and food has been found in the stomach despite normal fasting before a procedure — the reason pulmonary aspiration is on these labels.
Separately, Trulicity carries a boxed warning. In rats this molecule caused thyroid C-cell tumors. Whether it does so in people is unknown, and the label carries that as a boxed warning. It is contraindicated outright with a personal or family history of medullary thyroid carcinoma or MEN 2.

Would switching drugs help?
Vomiting is on 11 of the 13 FDA labels tracked here, so the other labels are worth reading before assuming a switch avoids it. What a switch does change is what you pay, and Trulicity is $389 a month at the maintenance dose here.

The listing, the schedule and the warnings are read from FDA prescribing information for TRULICITY, published 2026-08-10; the notes on why it happens and what helps are general guidance, not label text. Information only, not medical advice — a symptom that worries you is a call to your prescriber, not a search result.
