Understanding the correct locations for Ozempic injections and mastering the preparation and administration techniques are important, regardless of your reasons for using the drug.

Key Facts

  • The best areas for injecting Ozempic are the abdomen, front of the thighs, and the back of the upper arms, where there is enough fatty tissue for subcutaneous (under-the-skin) injection.
  • The pen features a rotating dose selector for precise dosing, and it requires a pen needle to administer the medication. Users should perform a flow test with each new pen to ensure proper operation.
  • Proper injection technique involves preparing the injection site with an alcohol swab, inserting the needle at a 90-degree angle, and pressing the plunger to deliver the dose, followed by proper disposal of the pen needle.

Get to know your Ozempic pen

Ozempic is administered using an injector pen, commonly referred to as a “medication pen” or simply a “pen.” These pens are favored for their ease of use compared to traditional syringes, offering simple and precise dosing. 

Anatomy of the Ozempic pen

The Ozempic pen is about 6 inches long, featuring a cap on one end and a small plunger button on the other. 

Removing the cap reveals the pen tip, a clear medication chamber, and a label with medication details. Just behind these features is a rotating dose selector dial, located in front of the plunger button.

Understanding the pen needles

For first-time users, note that the pen typically does not include a pen needle right out of the box. Pen needles, essential for administering a dose, are compatible across most brands, though they vary in length and gauge. 

While pen needles sometimes come bundled with the pen, if they are not included, ensure you receive a separate prescription for them. The standard needles provided are often NovoFine Plus needles, which are narrow-gauge and designed for use with this specific type of pen.

Setting the dose

The dose selector dial on the pen allows for adjusting the medication dosage in milligrams (mg). By rotating the dial clockwise, you increase the prepared dose. Each “click” aligns a new dose amount in the window, helping you set the exact dose prescribed by your doctor.

What does a dose look like?

The dose prescribed by your doctor corresponds to the amount you will need to dial in on your Ozempic pen. A single pen contains multiple doses, typically sufficient for at least one month of treatment.

Pens come in three dose sizes:

  • 0.25 mg or 0.5 mg: For dose escalation at the beginning of treatment
  • 1 mg: Standard dosage pen
  • 2 mg: For higher dosage requirements

Ensure the dose options on the pen’s packaging match the prescription from your doctor. Never exceed the prescribed dose to avoid potential adverse side effects.

Where is the best place on my body to inject Ozempic?

Ozempic must be administered subcutaneously — just under the skin — to be effective. It’s best to inject into areas of your body that have a layer of fatty tissue, which helps with absorption and minimizes discomfort. 

The most suitable sites for injections are:

  • Abdomen: Avoid the area 2 inches around the navel
  • Front of the thighs: Choose a spot away from the direct midline or any muscular regions
  • Upper arms: Particularly the backs, where there is typically more fatty tissue

Avoid injecting into lean or muscular areas, as this can be painful, cause more bleeding than usual, and potentially reduce the drug’s effectiveness. 

It’s also important never to inject Ozempic into a vein or artery, or into skin that is swollen, scarred, or otherwise damaged. This careful selection of injection sites ensures that Ozempic is delivered effectively and with minimal discomfort.

How to inject Ozempic

Inject Ozempic under the skin into fatty tissue once a week, consistently on the same day each week.

Prepare your pen

Gather your Ozempic pen and an alcohol swab.

Remove the pen cap and attach a pen needle.

If it’s your first time using this pen, check the flow by turning the dose selector clockwise until two dots and a line appear, indicating the needle is ready. Depress the plunger slightly. 

If a drop or two of liquid emerges, the pen is ready. If not, adjust or replace the needle as needed.

Dosing

Rotate the dose selector dial clockwise to the prescribed dose. If you overshoot, adjust by turning it counterclockwise until the correct dose aligns with the arrow.

Injection site preparation

Choose a spot with fatty tissue, such as your stomach (at least 2 inches from your belly button), upper thighs, or the backs of your upper arms. Avoid using the same spot each week to minimize skin reactions.

Swipe the selected area with the alcohol swab.

Injecting the dose

Remove the pen cap and hold the pen at a 90-degree angle to your body. Insert the needle fully into the skin and press the plunger button, ensuring the dose counter resets to zero.

Keep the needle in place for about 6 seconds to ensure the entire dose is delivered.

After-injection care

Remove the needle from the pen and safely dispose of it in a sharps container.

Replace the cap on the Ozempic pen, storing it safely until your next weekly dose.

A small amount of bleeding is normal; apply pressure with your alcohol swab if necessary.

Frequently asked questions

How do I know if I injected Ozempic correctly?

Always conduct a flow test when using a new pen to ensure that the pen and needle function properly together.

During injection, watch the dose selector window to confirm it returns to “zero” after administering your dose, indicating a full dose has been delivered.

Keep the needle inserted under the skin for 6 seconds to ensure complete delivery of the medication.

Ensure you inject into an area with fatty tissue, such as the back of the upper arms, abdomen, or thighs, following the proper injection technique.

If you are unsure or think you might have made an error, do not hesitate to contact your doctor or pharmacist for guidance.

What is the best time of day to inject Ozempic?

There is no clinically demonstrated best time of day to take Ozempic. Rather, the most important thing is to select a day of the week and consistently take it on that same day each week.

If you decide to take Ozempic on a Wednesday morning, for instance, you should plan to be consistent by taking your weekly dose of Ozempic each Wednesday morning for as long as you use the medication. If you happen to forget to take it in the morning, you can take it any time of the day.

Because of this, many people decide to write the day of the week they take the drug on a calendar or on the box that their Ozempic pen comes in. Phone reminders are also helpful to make sure you don’t miss a dose. 

What do I do if I missed a dose of Ozempic?

If you miss your scheduled dose of Ozempic, take it as soon as you remember, provided it’s within 5 days of the missed dose.

If it has been 5 days or more since the missed dose, skip it and proceed with your next regularly scheduled dose.

Missing a single dose of Ozempic is unlikely to significantly impact your blood sugar levels or insulin resistance, so there’s no need to worry if you occasionally forget a dose.

What do I do if my Ozempic pen doesn’t have a needle?

Ozempic pens are provided without a needle attached. You will need a needle for the pen to function.

Pen needles are typically included with your Ozempic prescription. These needles are designed for single use and should be discarded after one injection.

To attach a needle, align it with the top of the pen and twist it clockwise until secure.

Does it hurt to inject Ozempic?

Whether or not the injection hurts can vary from person to person, especially for those who are uneasy with needles. However, many people find that injecting Ozempic causes little to no pain.

In a study, over half of the participants (52 percent) who used semaglutide, the main component of Ozempic, reported feeling no pain during the injection. Additionally, 39 percent described any pain they felt as very mild.

This minimal discomfort might be due to the very thin needle used for the injection and the small amount of medication administered, which is typically between 1.5 to 3 milliliters, depending on the dosage.
