Sublingual Semaglutide Drops: What the Evidence Shows

No one has shown that sublingual semaglutide drops work in people. There is no FDA-approved sublingual semaglutide, and we found no published human study measuring how much semaglutide from drops, lozenges or under-the-tongue tablets reaches the blood. The approved semaglutide pill shows how hard needle-free delivery is: with a purpose-built absorption enhancer and strict dosing rules, its label puts absorption at about 1% to 2% of the dose.

What sublingual semaglutide is

“Sublingual semaglutide” is a compounded preparation: a pharmacy mixes semaglutide into drops, a lozenge (sometimes called a troche) or a tablet meant to dissolve under the tongue. Every semaglutide label on DailyMed is an injection or a tablet you swallow; none is a sublingual, buccal or liquid form.^[1][2] FDA says a compounded drug carries no FDA approval and gets no agency check of its safety, effectiveness or quality before sale.^[3]

The pitch is that the thin tissue under the tongue lets a drug skip the stomach. Semaglutide is a large peptide, about 4,114 daltons,^[6] the same size problem that rules out GLP-1 patches. See our glossary entry on sublingual troches for the dosage form itself.

The approved oral semaglutide, and what it needs to work

Two approved tablets exist. The Wegovy tablet is approved for weight reduction in adults who have obesity, or who are overweight and also have a condition linked to their weight.^[1] Rybelsus is approved for adults with type 2 diabetes, and its current label also covers Ozempic tablets.^[2] Both are swallowed, not dissolved in the mouth, and both contain SNAC (salcaprozate sodium), which the labels describe as an absorption enhancer.^[1][2]

Even with SNAC, absorption is fragile enough that the labels set strict rules:

• Take it first thing in the morning, before any food.^[1]
• Use plain water only, 4 ounces at most.^[1][2]
• Then hold off on food, drinks and other pills for half an hour or longer.^[1]

Sources: the Wegovy and Rybelsus labels.^[1][2] Our comparison of the Wegovy pill and the shot covers how the two approved forms compare in trials.

What has been tested for drops and other mouth forms

We searched PubMed in September 2026 for sublingual and buccal semaglutide and for sublingual or buccal GLP-1 drugs in general, and read every abstract. None reports a human study measuring blood levels, weight or blood sugar after sublingual or buccal semaglutide. The published work is in animals, plus one human study of whether people would wear a cheek patch:

The study closest to a commercial drop is the rat study, whose authors work in research and development at a compounding-supply company. It gave the sublingual group a dose of 1 mg/kg, about 90 times the injected dose of 0.011 mg/kg, and still reached a relative bioavailability of about a third of one percent.^[4] The better animal results all came from engineered systems, such as enhancer-loaded films, suction patches and new carrier peptides, that are not what a dropper bottle contains.

In people, one registered trial run by a telehealth company, NCT07092605, includes a weekly sublingual GLP-1 arm. It lists its status as enrolling by invitation and has posted no results.^[10] A 2026 survey of compounded GLP-1 products sold online found that 82% of the single-ingredient semaglutide and tirzepatide products it identified were sublingual, and concluded that whether these forms “offer advantages over innovator oral tablets has not been determined.”^[9]

Why a milligram in a dropper is not a milligram in a pen

The approved labels show why. The Wegovy tablet’s maintenance dose is 25 mg every day, or 175 mg a week, to do the work of a 2.4 mg weekly injection.^[1] That is about 73 times as much drug by mouth. The Rybelsus label also says its own tablets and Ozempic tablets “are not substitutable on a mg-to-mg basis,” even though both are approved, swallowed and made with the same enhancer.^[2]

If two approved tablets cannot be swapped milligram for milligram, a drop with a different vehicle, a different route and no published absorption data cannot be assumed to match either. The dose on a compounded bottle tells you how much semaglutide went in. It does not tell you how much reaches your blood.

What sellers charge for semaglutide drops and lozenges

Of the sellers we track, 29 list a drop, sublingual or lozenge form of compounded semaglutide with its own price. Starting prices run from $99 to $400 a month. Prices were last checked on each seller’s site between September 2026 and November 2026; click a name for the full review.

These prices buy a preparation with no published human absorption data, so a cheaper bottle is not necessarily better value. The sellers of drops, troches and dissolving tablets are on our sublingual semaglutide board. Compare every non-injected option, including tablets, on our oral GLP-1 provider board, and see compounded versus brand semaglutide for the wider trade-off.

Other sellers offer compounded semaglutide by mouth in forms outside that table, and the same absorption caveat applies. MedLeanRx, a Texas-only service, sells a daily oral tablet, and Rila sells a dissolvable tablet whose lowest advertised rate assumes a 6-month commitment. He & She MD, Rivo Health and Go Vida Plena list oral versions of compounded semaglutide and tirzepatide without describing the form on their public pages, so ask what it is before you order. HealthSource sells compounded tirzepatide as an oral sublingual, a form with no approved counterpart at all. The Wellness Company sells a compounded 10 mg tirzepatide tablet dissolved under the tongue once a day, at $349.99 every 30 days. MEDVi sells a compounded GLP-1 tablet that dissolves once a day, alongside its weekly injection. Flo Clinic, which serves New Jersey and New York, sells compounded semaglutide and tirzepatide as daily dissolving tablets, and its oral semaglutide starts at $364.99 a month against $214.99 for its starter injection, plus $35 shipping on each. North Carolina Trim Clinic offers an under-the-tongue tablet beside its weekly injections, though its only published price is a $149-a-month starting figure for the injectable program.

Lavender Sky Health lists sublingual semaglutide and sublingual tirzepatide plans from a compounding pharmacy, sold as fixed 60-day supplies rather than monthly refills. Riovie sells compounded semaglutide and tirzepatide as sublingual tablets alongside its injections, and on its one-month plan the semaglutide tablet costs $209 against $149 for the semaglutide injection. Thrivelab also charges more for the mouth form: its oral semaglutide, taken daily under the tongue, is $225 for the first month and from $300 a month after that, against $175 to $250 a month for its injections. Rejuvenate MedSpa sells oral tirzepatide as an extended-release troche taken once a week, priced by dose up to $490 a month at 40 mg a week.

If you want semaglutide without injections

The Wegovy tablet is the approved way to take semaglutide for weight loss without a needle. Its label carries the dosing rules above and its own trial results.^[1] Our Wegovy guide covers both forms, and brand semaglutide providers lists sellers who prescribe the branded drug. For type 2 diabetes, see Rybelsus. Brand names can be confusing here; brand names versus molecules sorts out which product contains which drug. For another oral option, see our Foundayo guide.
