Instructions: Tirzepatide Injection
Your Complete Guide to
Tirzepatide Injection Treatment
A simple step-by-step guide to preparing, injecting, storing, and safely using your prescribed tirzepatide.
How to Use Your Tirzepatide Injection
Tirzepatide is injected subcutaneously, just under the skin, once weekly. Always follow the exact dose and number of units shown on your prescription label.
Wash your hands thoroughly. Gather your tirzepatide vial, a new sterile syringe and needle, alcohol swabs, and a sharps disposal container.
Check your medication and prescription label. Clean the rubber stopper with an alcohol swab and allow it to dry before drawing your dose.
Using a new sterile syringe and needle, carefully draw the exact number of units listed on your prescription label. Do not estimate or change your dose on your own.
Choose the abdomen, thigh, or upper arm as directed. Rotate injection sites each week. Clean the area with an alcohol swab and allow it to dry.
Gently pinch the skin if needed and insert the needle into the fatty tissue beneath the skin. Slowly press the plunger until your prescribed dose has been administered.
Place the used needle and syringe immediately into an appropriate sharps disposal container. Never reuse or share needles or syringes.
How to Prepare Your Syringe
Prepare your injection on a clean surface and use a new sterile syringe and needle for every dose. Check your prescription label before drawing medication from the vial.
Confirm your medication, vial concentration, prescribed dose, and the exact number of syringe units listed on your prescription label.
Wipe the rubber stopper on the vial with an alcohol swab and allow it to dry completely.
Remove the syringe from its packaging. Do not touch the needle or allow it to contact any non-sterile surface.
Insert the needle through the center of the rubber stopper. Turn the vial upside down while keeping the needle tip positioned within the liquid medication.
Slowly pull back the plunger until it reaches the exact syringe marking specified on your prescription label.
Confirm the amount before removing the needle from the vial. If you are unsure about the syringe markings or your prescribed units, contact DoctorAdam or your dispensing pharmacy before injecting.

⚠️ Avoid These Common Mistakes
Your Tirzepatide Dosing Plan
Tirzepatide dosing is increased gradually to help your body adjust to treatment. Your healthcare provider may modify your schedule based on your response and tolerability.
When to Take Tirzepatide
Take your injection once weekly on the same day each week. Tirzepatide may generally be administered at any time of day, with or without food.
Where Can I Inject Tirzepatide?
Tirzepatide is injected into the fatty tissue just beneath the skin. Rotate the exact injection location each week.
Recommended Subcutaneous Injection Areas

Common injection areas include the abdomen, thigh, and back of the upper arm. Rotate the exact injection spot each week.
Use an appropriate fatty area of the abdomen and avoid injecting immediately around the belly button.
The front or outer portion of the upper thigh may be used for your injection.
The fatty area at the back of the upper arm may also be used when appropriate.
Possible Side Effects
Side effects may occur when beginning tirzepatide treatment or after a dose increase. Gastrointestinal side effects are among the most commonly reported.
💡 Eating smaller meals and staying adequately hydrated may help with some gastrointestinal symptoms.

Frequently Asked Questions
Q: How often do I inject tirzepatide?
Tirzepatide is generally injected once weekly. Follow the schedule shown on your prescription label.
Q: Where should I inject it?
Tirzepatide is injected under the skin of the abdomen, thigh, or upper arm. Rotate the exact injection location each week.
Q: What is a unit on my syringe?
A unit is a volume marking on the syringe. On a U-100 syringe, 100 units equals 1 mL. Units are not the same as milligrams of tirzepatide.
Q: Is 10 units the same as 10 mg?
No. Units measure liquid volume, while milligrams measure the amount of medication. The amount of tirzepatide contained in 10 units depends on the concentration of your vial.
Q: How many units should I inject?
Use only the number of units printed on your prescription label. Units depend on the concentration of your medication, so never use another patient's dosing chart or calculate a different dose yourself.
Q: What if I cannot understand the syringe markings?
Do not guess. Contact DoctorAdam or your dispensing pharmacy before injecting if you are unsure which syringe marking corresponds to your prescribed dose.
Q: Can I increase my dose if I'm not seeing results?
Do not increase your dose on your own. Your healthcare provider determines whether and when a dose increase is appropriate based on your response and tolerability.
Q: What should I do if I miss my injection?
Follow the missed-dose instructions provided with your prescription. If you are unsure what to do, contact your healthcare provider or dispensing pharmacy. Do not take extra medication to compensate for a missed dose unless specifically instructed.
Q: Can I use the same injection area each week?
You may use the same general body area, but rotate the exact injection spot each week to help reduce irritation.
Q: Can I reuse my syringe or needle?
No. Always use new sterile injection supplies for each dose and dispose of used needles and syringes safely after use.
Q: What should my medication look like?
Inspect your medication before each injection. If it appears unexpectedly cloudy, discolored, contains particles, or looks different from what your pharmacy instructed you to expect, contact your dispensing pharmacy before using it.
Q: How long will I stay on each dose?
The DoctorAdam treatment schedule generally progresses monthly. Your provider may keep you on a dose longer or modify your treatment depending on your response and tolerability.
Q: What if I'm not seeing results yet?
Individual response varies. Early treatment focuses on gradually increasing the medication while monitoring tolerability. Continue following your prescribed plan and discuss your progress with your healthcare provider before changing your dose.
