Titration schedule, missed dose, and forms
| Treatment phase (label) | Dose | How long before considering an increase |
|---|---|---|
| Starting dose | 2.5 mg once weekly | After 4 weeks |
| Dose escalation | Increase by 2.5 mg steps (for example 5 mg, 7.5 mg, 10 mg, 12.5 mg, 15 mg once weekly) | At least 4 weeks at each dose |
| Maintenance dose | 5 mg, 10 mg, or 15 mg once weekly | Chosen by prescriber based on response and tolerability |
What “maintenance dose” means
A maintenance dose is the ongoing weekly dose your clinician selects after titration. The label lists multiple maintenance options because people vary in side effects, other medications, and how much additional benefit they get at higher doses.
If you miss a dose
The label says you can take a missed dose within 4 days (96 hours). If more than 4 days have passed, skip the missed dose and take your next dose on the regularly scheduled day.
Changing your weekly injection day
The label allows changing the day of weekly administration if the time between doses is at least 3 days (72 hours). If you are considering a change, confirm the timing with your prescriber or pharmacist.
Injection sites (label only)
For FDA approved tirzepatide pens, the label lists injection in the abdomen, thigh, or upper arm. A clinician or pharmacist should show you how to use the device, and the Instructions for Use cover the steps.
Compounded tirzepatide is different
Compounded tirzepatide is prepared by a licensed pharmacy for an individual prescription and is not FDA-approved. Your prescribing clinician and dispensing pharmacy provide the specific administration instructions for that product.
When to talk to a clinician urgently
Possible pancreatitis symptoms
Seek urgent medical evaluation for severe abdominal pain that may radiate to the back, with or without vomiting. Pancreatitis has been reported with GLP-1 based medicines, and the label advises stopping tirzepatide if pancreatitis is suspected.
Gallbladder problems
Contact a clinician promptly for right upper abdominal pain, fever, jaundice, or clay-colored stools. Acute gallbladder disease has been reported with tirzepatide, and symptoms may need imaging and treatment.
Kidney problems or dehydration
If vomiting or diarrhea is persistent, or you cannot keep fluids down, contact a clinician. The label warns that severe gastrointestinal reactions can lead to dehydration and worsening kidney function, especially in people with kidney disease.
Low blood sugar risk (hypoglycemia)
If you use insulin or a sulfonylurea, ask your prescriber about hypoglycemia risk and monitoring. Symptoms can include shakiness, sweating, confusion, or fast heartbeat and may require prompt treatment.
Thyroid tumor warning symptoms
Tirzepatide has a boxed warning about thyroid C-cell tumors based on animal studies. Contact a clinician if you notice a neck lump, hoarseness, trouble swallowing, or shortness of breath.
Allergic reaction
Get emergency care for swelling of the face, lips, tongue, or throat, trouble breathing, or severe rash. Serious hypersensitivity reactions have been reported.
Practical tips to stay on track
Expect appetite changes
Dose increases can temporarily worsen nausea. Smaller meals and slower eating may help.
Plan around titration weeks
If side effects flare after an increase, tell your clinician before the next scheduled step up.
Track symptoms, not just weight
Note nausea, constipation, reflux, and fatigue patterns to guide clinician decisions.
Review other diabetes medicines
If you take insulin or sulfonylureas, ask about hypoglycemia precautions during titration.
Ask before changing dose timing
The label has timing rules for missed doses and day changes. Confirm your plan with your prescriber.
