What is sublingual semaglutide?

Sublingual semaglutide is prepared by compounding pharmacies as a rapid-dissolve tablet (RDT) or liquid held under the tongue, where a portion of the drug absorbs directly through the oral lining into the bloodstream. Typical protocols dose it weekly, mirroring injection rhythm, with ladders in the 1–6 mg range. Three distinctions people regularly get wrong: 1. It is not Rybelsus. Rybelsus is FDA-approved oral semaglutide that you swallow, absorbed in the stomach via a special carrier. Sublingual products are compounded, absorbed in the mouth, and unreviewed by FDA. 2. Its milligrams are not injection milligrams. Oral-mucosa absorption is lower and more variable than subcutaneous injection, so sublingual ladders use different numbers. “3 mg sublingual” tells you nothing about its relationship to “1 mg injected” — treat the scales as unrelated. 3. It is legal but unproven. Licensed pharmacies may compound it for individual prescriptions; what’s missing is randomized-trial evidence (how well does it work?). A variant pairs semaglutide with vitamin B6 for nausea mitigation (details). A handful of telehealth weight programs offer sublingual options — NexLife carries the widest sublingual range (plain RDT and B6 versions of semaglutide, plus a tirzepatide RDT); vet any program against the checklist on where to get GLP-1s, and treat one that calls sublinguals “the same as Wegovy” as disqualified by dishonesty.
