This page explains the general shape of using a prescription medicine in this class. It is not your instructions. Your instructions come from the clinician who prescribed for you, the label on what the pharmacy dispensed, and the Medication Guide in the box.
Important safety information. Tirzepatide is the active ingredient in Mounjaro and Zepbound, which are FDA-approved prescription medicines from Eli Lilly and Company. These branded medicines carry a boxed warning about the risk of thyroid C-cell tumors. They should not be used by people with a personal or family history of medullary thyroid carcinoma, or by people with Multiple Endocrine Neoplasia syndrome type 2. Serious risks can include pancreatitis, gallbladder problems, acute kidney injury, severe stomach and intestinal reactions, serious allergic reactions, low blood sugar when taken with certain other diabetes medicines, and diabetic retinopathy complications. Read the official Prescribing Information and Medication Guide for each one: Mounjaro and Zepbound.
This page is general information, not medical advice. Talk to a licensed clinician about your situation.
The label is the authority
For an FDA-approved product, the Prescribing Information and the Medication Guide describe the approved uses, the dosing, how and where to inject, how to store it, what to do about a missed dose, and the full risk information.
Those documents are linked above, and they are the source to read. No article, forum post, or video replaces them. If something on the internet conflicts with the Medication Guide in your box, the Medication Guide wins.
The second authority is the person who prescribed for you, because they know your history, your other medicines, and why they chose what they chose.
What the general routine looks like
The approved tirzepatide products are labeled as an injection given under the skin once a week, on the same day each week. It comes from the pharmacy as a single-dose device or vial, depending on what was dispensed.
Common injection areas described in the labeling are the abdomen, thigh, or upper arm, with the site rotated. A pharmacist or clinician can walk you through the first injection, and it is reasonable to ask for that rather than working it out alone.
Storage matters. The labeling specifies refrigeration conditions, a limited period at room temperature, and instructions about light and freezing. Read that section before the first fill goes into a bag or a car.
Used needles and devices go into a sharps container, not household trash.
That is the shape of it. The specifics, including your dose, any dose changes over time, and what to do if you miss a week, belong to your clinician and your label.
Why dose changes are a clinician's call
Medicines in this class are typically started low and adjusted over time under clinical supervision. The schedule is written into the approved labeling, and a clinician applies it to you.
Do not adjust on your own. Taking more does not speed anything up and increases risk. Stretching a supply to make it last, skipping doses to save money, or splitting a dose changes what you are actually taking, and the clinician managing your care cannot account for what they do not know.
If cost or supply pressure is pushing you toward one of those choices, call the prescribing clinician and the pharmacist first. That conversation has better options in it than the ones you can improvise alone.
Side effects and when to call
The labeling lists common side effects and the serious risks summarized at the top of this page, including the boxed warning. Read that section fully rather than skimming it.
Call your clinician about anything that concerns you, and seek urgent care for severe or persistent abdominal pain, persistent vomiting, signs of an allergic reaction, or anything the Medication Guide flags as urgent. Keep the pharmacy number where you can find it.
Tell every clinician you see, including dentists and surgeons, that you are taking this medicine. It can matter for procedures and for other prescriptions.
Compounded tirzepatide has no FDA-approved label
This is the practical difference people most often miss, and it changes where instructions come from.
Compounded medications are not FDA-approved. FDA does not review them for safety, effectiveness, or manufacturing quality.
Compounded tirzepatide is not Zepbound, not Mounjaro, not Ozempic and not Wegovy. It is not a generic version of any approved drug, and it is not interchangeable with one. FDA's overview of human drug compounding describes the category.
Because a compounded preparation is not an approved finished drug product, there is no FDA-approved Prescribing Information or Medication Guide behind it. Directions come from the prescribing clinician and the dispensing pharmacy, and the concentration and presentation can differ from anything you have read about elsewhere. Never apply instructions written for one product to a different one.
Compounded tirzepatide may be dispensed only pursuant to a valid prescription issued by a licensed clinician after a clinical evaluation, and only from a state-licensed pharmacy. If you have one in hand and the directions are unclear, call the pharmacy that dispensed it before you use it.
What Body Good's role is here
Body Good is a clinical service. Its prices are service fees for the program described at intake, covering the clinical evaluation and the ongoing care and support in that program. They are not the price of medication and are not a quote for any individual. Eligibility is determined by a clinician.
The cost of medication is separate and is not included in a Body Good service fee.
Body Good provides coverage support, which means help checking benefits and preparing the paperwork a plan requests. What a plan approves and pays is determined by the plan.
This site is an information and pricing overview only. It takes no payment, collects no health information, and runs no intake form. Intake happens on joinbodygood.com.
Frequently asked questions
What day of the week should I inject?
The approved labeling describes a once-weekly injection on the same day each week, and your clinician confirms the day and the timing that fit your situation. Keep it consistent once it is set.
What should I do if I miss a dose?
Follow the missed dose instructions in the Medication Guide for the exact product you were dispensed, and call your pharmacist or clinician if it is not clear. Do not double up to catch up.
Can I learn the injection technique from a video?
Use it as a supplement, never as the source. Ask your pharmacist or clinician to watch you do the first one. Begin Body Good's clinical intake if you want a clinician to review your situation.
