ODT stands for “oral dissolving tablet.” You place it under your tongue and let it dissolve fully — no chewing, no swallowing, no water. The tirzepatide is absorbed sublingually through the mucous membrane under your tongue, bypassing the stomach and most first-pass liver metabolism. Once in circulation, it activates both GLP-1 and GIP receptors — the same dual mechanism as the injection — to reduce appetite, slow gastric emptying, improve insulin sensitivity, and quiet food noise.

Both formulations contain the same active ingredient. The injectable form has been more extensively studied in clinical trials and generally produces the most predictable bioavailability, which is why it’s considered the gold standard. Sublingual ODT is a strong alternative for patients who are needle-averse or travel frequently. Your provider will prescribe a dose calibrated to target clinically meaningful weight loss and monitor your progress each month through the Patient Portal.

No needles, no syringes, no sharps container, no injection anxiety, and no TSA hassle when you travel. You take your dose discreetly in seconds — perfect for needle-phobic patients, frequent flyers, and women who simply don’t want a weekly shot. Many women tell us ODT was the only reason they finally started GLP-1 therapy.

Place one tablet under your tongue and let it dissolve completely — typically 60–90 seconds. Avoid food, drinks, and brushing your teeth for at least 30 minutes afterward so the medication can absorb. Take it on the same day each week, per your provider’s dosing schedule. Your care team will walk you through the exact protocol after your prescription is written.

Yes. If you’re currently on injectable tirzepatide and want to switch to ODT — or you’ve been on ODT and want to move to the injection — your provider can evaluate the switch and update your prescription. Message them through the Patient Portal to discuss timing, dosing, and what to expect during the transition.

The ODT shares the same side effect profile as injectable tirzepatide: nausea, reduced appetite, constipation, diarrhea, and mild fatigue — most pronounced during dose titration. Some patients find sublingual administration easier on the stomach. Eat smaller meals, stay hydrated, and let your provider know if anything persists. Side effects typically fade within the first 4–6 weeks as your body adjusts.
