Have you
recently been prescribed a GLP-1 weight loss medication like compounded semaglutide or compounded tirzepatide? Follow our step-by-step guide
on how to inject semaglutide or tirzepatide.
This guide is
for semaglutide or tirzepatide that comes in a vial and is injected with a
syringe – not for name-brand autoinjector pens.
Semaglutide
and Tirzepatide Injection Sites
Semaglutide and tirzepatide are administered as
subcutaneous injections, which means injecting into a layer of fat underneath
the skin. Finding a spot with fat instead of muscle is easier and lowers the
risk of impacting a nerve or blood vessels. The three recommended spots are in
the stomach, thigh and arm.1
Stomach
The stomach is a convenient location
to inject because it is easy to reach and has a layer of fat. The suggested
spot on the stomach is approximately 2 inches from the belly button.
Thigh
The thigh is another naturally fatty
body part that is easy to reach. Inject into the front of the thigh, avoiding
the inner thigh.
Upper Arm
Choose a spot between the elbow and shoulder to inject
into the upper arm. This is a good choice for those who want a less visible
spot.2
How
Often to Rotate Injection Sites
Rotating to a different body part each week can help
you avoid irritation, discomfort and changes in the skin at the injection site.
Always follow your provider’s directions for specific injection instructions.3
Step-by-Step
Semaglutide and Tirzepatide Injection Guide
When you receive your medication, you should have a
vial of your prescribed medicine, alcohol wipes and enough syringes to last one
month. Follow the step-by-step guide below or watch this video to properly inject your semaglutide or
tirzepatide with a syringe and vial.
Drawing Your
Medication
1. Check the medication label to
ensure it matches the dosage prescribed by your provider.
2. Remove the lid from your vial.
3. With the syringe cap still on, pull back the plunger
to the 20-mark (0.2 ml) on your syringe to fill it with air.
4. Remove the syringe cap, insert the needle into the
rubber top of the vial and push all the air into the vial.
5. Turn the vial upside down and pull the plunger back
to the prescribed amount of medication (e.g., 20 units.).
6. If air bubbles are present, tap the
syringe with your finger until the bubbles rise, then gently push the plunger
to push the air back into the vial.
Injecting Your
Medication
1. Rotate your injection site to be at least 1.5 inches
away from the last site.
2. Cleanse the chosen area with an alcohol wipe and let
it dry.
3. Pinch a 2-inch skin fold between your thumb and
index finger.
4. Hold the syringe like a pencil or dart, and insert
the needle at a 45- to 90-degree angle into the pinched skin.
5. Hold the syringe with one hand and slowly push the
plunger to inject the medication until it's fully depressed.
6. Remove the needle and gently hold
an alcohol pad on the injection site without rubbing.

Injection
Tips and Reminders
Here are a few tips and reminders to help you have the
best experience while using GLP-1 weight loss medications.
Semaglutide and tirzepatide should be injected once per
week, on the same day each week. The injection can happen any time of day. You
can take these medications with or without food.7, 8
Medication
Storage
Tirzepatide and semaglutide injections should be stored
in the refrigerator (between 36 and 46 degrees Fahrenheit). Keep tirzepatide in
its original packaging until use to protect it from light. Store your
medication only as directed.
Keep medications and injection supplies out of reach of children.10
Missed Dose
If you miss a dose of semaglutide and
the next dose is more than two days away, use the missed dose as soon as
possible. If you miss a dose of semaglutide injection and the next scheduled
dose is less than two days away, skip the missed dose and continue your regular
dosing schedule. If you miss a dose of semaglutide injection for more than two
weeks, contact your provider.11
If you miss a dose of tirzepatide, take it as soon as
you remember it within four days after the missed dose. However, if more than
four days have passed, skip the missed dose and continue your regular dosing
schedule. Do not inject two doses within three days of each other.12
How Long for
Semaglutide or Tirzepatide Injection Results
Results from semaglutide and
tirzepatide will vary among individuals. Your genetics, diet and lifestyle all
contribute to your weight loss results. In general, the following is what you
can expect for a GLP-1 timeline.
Weeks One-Four
You may start to notice a reduction in
appetite and an increased feeling of fullness after eating.
Weeks Five-20
As your dose increases, you may notice
more influence on your appetite. Weight loss results may start to be noticeable
in this phase.
Weeks 20 and beyond
Your weight loss journey can continue with semaglutide
or tirzepatide until you reach your weight loss goals. If you continue with a
regular medication schedule and a nutritious diet, these medications can lead
to sustained weight loss and improved metabolic health.13
