How a prescription works in Washington.

You don’t have to leave Washington to start. Because tirzepatide isn't a controlled substance, a Washington-licensed prescriber can evaluate you by telehealth and send the script to a pharmacy near you, or you can see one of the 936 local providers below in person. What you pay depends on your plan, not your zip code.

Telehealth
Available in Washington
Zepbound (tirzepatide) is a GLP-1, not a controlled substance, so a Washington-licensed clinician can assess you and prescribe over video, with no federal in-person-visit requirement.
Who can prescribe
WA-licensed clinicians
Any physician, nurse practitioner, or PA licensed in Washington can prescribe Zepbound. The 936 providers below are checked against the NPI registry and the Washington board.
Medicaid (weight loss)
Diabetes only
As of April 2026, Washington Medicaid covers GLP-1s for diabetes but not for weight loss. Employer and private plans can still cover them; that is a plan-design choice, not a state rule.

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 Washington’s current Medicaid and plan rules before booking. GLPHelper provides information and provider matching, not medical or coverage advice.

§ 04Medication factsheet
cited · last review 2026.05.19

An injectable medication for chronic weight management in adults. Same molecule as Mounjaro.

Zepbound is the brand name Eli Lilly uses for tirzepatide approved for chronic weight management. It is a once-weekly subcutaneous injection and the first approved dual GIP/GLP-1 receptor agonist. The identical molecule, marketed as Mounjaro, is the FDA-approved formulation for type 2 diabetes.[2][3]

In SURMOUNT-1, adults with obesity (without diabetes) lost a mean of 20.9% of body weight on the 15 mg dose at 72 weeks, versus 3.1% with placebo. That is among the largest average weight reductions reported for an anti-obesity medication. Zepbound is approved as an adjunct to a reduced-calorie diet and increased physical activity.[1]

Bar chart of Zepbound dose strengths on the FDA label: 2.5 mg, 5 mg, 7.5 mg, 10 mg, 12.5 mg, 15 mg
Zepbound comes in 6 strengths: 2.5 mg, 5 mg, 7.5 mg, 10 mg, 12.5 mg, 15 mg. The chart shows what the label lists. A prescriber sets the dose.[1]

STEP 1 to 4 + SELECT (N = 17,604)

What the trials actually showed.

We summarize the SURMOUNT weight-management program. Figures are means at the 72-week primary endpoint, by dose.

SURMOUNT-1 randomized 2,539 adults with obesity (without diabetes) across 72 weeks. Mean weight change was −15.0% (5 mg), −19.5% (10 mg), and −20.9% (15 mg) versus −3.1% with placebo. A majority of patients on the higher doses lost ≥20% of body weight.[2]

§ 06Safety & adverse events
from FDA label, sect. 6.1

Most Zepbound side effects are stomach and gut effects.

In Zepbound's weight trials at 5 to 15 mg, the most common side effects were nausea (25 to 29%), diarrhea (19 to 23%), constipation (11 to 17%), and vomiting (8 to 13%). 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]

Zepbound and Mounjaro are both tirzepatide, made by Eli Lilly, but they carry different FDA-approved indications. Zepbound is approved for chronic weight management; Mounjaro is approved for type 2 diabetes. Insurers treat them as separate products, and weight-loss coverage is far more restricted than diabetes coverage.[1]
