How GLP-1 prescribing works in 2026: a complete guide for med spa owners
June 2026 · 8 min read
GLP-1 medications went mainstream faster than most clinics could build the workflow around them. Here is how prescribing actually works in 2026 — from who qualifies to how doses are escalated — without the hype.
GLP-1 receptor agonists — semaglutide and tirzepatide — have become the backbone of modern medical weight management. For a med spa or clinic adding a program, the hard part is not the medication; it is the workflow around it: deciding who qualifies, escalating doses safely, and keeping patients in follow-up.
Who qualifies
Eligibility for weight management generally starts at a BMI of 30 or above, or 27+ with a weight-related condition such as hypertension or type 2 diabetes. Pregnancy, a personal or family history of medullary thyroid carcinoma, and a few other conditions are absolute contraindications.
How titration works
GLP-1s are started low and increased gradually to limit gastrointestinal side effects. Semaglutide typically begins at 0.25 mg weekly and steps up roughly every four weeks; tirzepatide starts at 2.5 mg on a similar cadence. The schedule is not a race — patients who tolerate a dose poorly hold or step back rather than push ahead.
- Start at the lowest dose and hold for the protocol interval.
- Step up only when the current dose is tolerated.
- Slow down or pause for significant nausea or GI symptoms.
- Document tolerance at each step — it is the basis for the next decision.
The visit flow
A typical program runs: structured intake → automated eligibility screen → provider review of anything flagged → prescription with a titration plan → pharmacy fulfillment → scheduled follow-up and refills. The clinician owns every clinical decision; software just makes the path repeatable and auditable.
The clinics that succeed treat GLP-1 as a longitudinal program, not a one-time script.
