How a prescription works in Illinois.
You don’t have to leave Illinois to start. Because tirzepatide isn't a controlled substance, a Illinois-licensed prescriber can evaluate you by telehealth and send the script to a pharmacy near you, or you can see one of the 1485 local providers below in person. What you pay depends on your plan, not your zip code.
Medicaid status above is for weight-loss use and was compiled April 2026 from KFF and public Medicaid trackers; only 13 states cover it and several are mid-change, so confirm Illinois’s current Medicaid and plan rules before booking. GLPHelper provides information and provider matching, not medical or coverage advice.
An injectable medication for adults with type 2 diabetes. Same molecule as Zepbound.
Mounjaro is the brand name Eli Lilly uses for tirzepatide approved for type 2 diabetes. It is a once-weekly subcutaneous injection and the first approved dual GIP/GLP-1 receptor agonist. It activates two gut-hormone pathways rather than one. The identical molecule, marketed as Zepbound, is the FDA-approved formulation for chronic weight management.[2][3]
In the SURPASS-2 head-to-head trial, tirzepatide produced greater HbA1c reductions and greater weight loss than semaglutide 1 mg across all doses. Across the SURPASS program, tirzepatide lowered HbA1c by approximately 1.8 to 2.6 percentage points. Mounjaro is approved as an adjunct to diet and exercise for glycemic control in adults with type 2 diabetes.[1]
What the trials actually showed.
We summarize the SURPASS diabetes program, including the SURPASS-2 head-to-head against semaglutide. Figures are means at each trial's primary endpoint.
Most Mounjaro side effects are stomach and gut effects.
In Mounjaro's diabetes trials at 5 to 15 mg, the most common side effects were nausea (12 to 18%), diarrhea (12 to 17%), decreased appetite (5 to 11%), and vomiting (5 to 9%). Most reports came during dose escalation and decreased over time.[1] Serious events were rare but include pancreatitis, gallbladder disease, and an FDA boxed warning regarding thyroid C-cell tumors based on rodent data.[1]

The price you pay depends on your insurance plan, your diagnosis, and how you buy. Manufacturer self-pay programs cost far less than pharmacy retail. Here are the ranges.

Mounjaro and Zepbound are both tirzepatide, made by Eli Lilly, but they carry different FDA-approved indications. Mounjaro is approved for type 2 diabetes; Zepbound is approved for chronic weight management. Insurers treat them as separate products, and coverage differs sharply between the two.[1]
In the SURPASS-2 head-to-head diabetes trial, tirzepatide produced greater HbA1c reductions and greater weight loss than semaglutide 1 mg across all doses. The two have not been compared head-to-head at their maximum weight-management doses, so direct weight-loss superiority outside diabetes is inferred rather than proven.[3]
Yes. Mounjaro is a prescription-only medicine, marked Rx only on its label. A licensed prescriber (MD, DO, NP, or PA) must evaluate you before issuing a prescription.[1]
For type 2 diabetes, most commercial plans cover Mounjaro with prior authorization, and Medicare Part D covers it for T2D. It is not covered for weight loss alone. Zepbound is the on-label option for obesity but is itself frequently restricted.[5]
In most states, yes. Telehealth prescribing is permitted once a practitioner-patient relationship is established, typically via a synchronous video visit, by a provider licensed in your state.[1]
