Giving yourself an Ozempic shot takes about two minutes once you know the steps. The pen comes pre-filled and uses a thin, short needle that most people barely feel. You inject it once a week, on the same day each week, at any time of day, with or without food.
Before You Start: Check the Pen
Look through the pen window and confirm the liquid inside is clear and colorless. If it looks cloudy, has any color to it, or contains visible particles or specks, don’t use it. A compromised pen should go into a sharps container, and you’ll need a replacement from your pharmacy.
If your pen is new and has been stored in the refrigerator, let it sit out for a few minutes to approach room temperature. Cold medication can sting more going in. Unused pens should be kept refrigerated between 36°F and 46°F. Once you start using a pen, it can stay at room temperature (up to 86°F) for 56 days, after which you should discard it even if medication remains.
Attach a New Needle
Each injection requires a fresh needle. Tear off the paper tab on the needle package, then push the needle straight onto the pen tip and twist it on until it’s snug. Pull off the outer needle cap first (save this one for later), then pull off the smaller inner cap and discard it.
Do the Flow Check (New Pens Only)
The first time you use a brand-new pen, you need to prime it to make sure medication is flowing properly. Turn the dose selector until the dose counter displays the flow check symbol. Then press and hold the dose button until the counter returns to zero. You should see a small drop of liquid appear at the needle tip. If no drop appears, repeat the process up to six times. You only need to do this once per new pen, not before every injection.
Select Your Dose
Turn the dose selector until the counter shows the dose your doctor prescribed. Ozempic pens come in different strengths, so make sure you’re dialing the correct number. Most people start at 0.25 mg once a week for the first four weeks. After that, the dose typically increases to 0.5 mg. Your doctor may raise it further in increments, with at least four weeks between each increase, up to a maximum of 2 mg per week.
The 0.25 mg starting dose is not meant to be therapeutic. It gives your body time to adjust and reduces the chance of nausea and other stomach-related side effects that are common in the first few weeks.
Choose and Rotate Your Injection Site
You have three options for where to inject:
- Abdomen: anywhere between your chest and groin, at least two inches from your belly button
- Front of your thigh: the fleshy middle area
- Upper arm: the back or side (this one is easier if someone else gives you the shot)
Rotate your injection site each week. If you used your right thigh last time, switch to your left thigh, your abdomen, or your upper arm. Even if you prefer one general area, pick a slightly different spot within that region each time. Repeating the exact same spot can cause the tissue underneath the skin to change over time, which affects how well the medication absorbs. Never inject into a muscle or vein. Ozempic goes into the fat layer just beneath the skin.
Give the Injection
Pinch a fold of skin at your chosen site if needed, though many people find they can inject without pinching. Insert the needle straight into the skin at a 90-degree angle. Press the dose button down and hold it. Watch the dose counter, and once it reaches zero, keep holding the button and slowly count to six. This pause makes sure the full dose is delivered. Then pull the needle straight out.
You might see a tiny drop of liquid at the injection site. That’s normal and doesn’t mean you lost part of your dose. Don’t rub the area. If you notice a small drop of blood, you can press lightly with a clean cotton ball or tissue for a few seconds.
Remove and Dispose of the Needle
Carefully place the outer needle cap back on (the larger one you saved earlier) and twist the needle off the pen. Drop it directly into a sharps disposal container. Never throw loose needles into household trash or recycling. Use a new needle for every injection, and never leave a needle attached to the pen between uses, as this can cause air bubbles or leaking.
Once your sharps container is about three-quarters full, seal it and dispose of it according to your local guidelines. Many pharmacies, hospitals, fire stations, and doctors’ offices serve as drop-off sites. Mail-back programs and special waste pickup services are also available in many areas. Put the pen cap back on the pen after removing the needle to protect the medication from light.
Tips for a More Comfortable Injection
Most people describe the Ozempic injection as nearly painless because the needle is very short and thin. But if you’re sensitive to needles or experiencing discomfort, a few adjustments can help.
Make sure the medication is at room temperature before injecting. You can also hold an ice pack wrapped in a cloth against the injection site for a few minutes beforehand to numb the area, though keep it to 15 minutes or less. Relax the muscle at the injection site. If you’re injecting into your thigh, try sitting down and letting the leg go loose. Tensed muscles make shots hurt more.
After injecting, applying gentle pressure to the site for five to ten minutes can reduce bruising. If you’re injecting in your thigh or arm, keep that limb moving throughout the day. Some mild redness, swelling, or itching at the site is common, especially in the first few weeks, and usually fades on its own.
What if You Miss a Dose
If fewer than five days have passed since your missed dose, take it as soon as you remember and then return to your regular schedule. If more than five days have passed, skip the missed dose entirely and take your next one on the usual day. Never take two doses to make up for a missed one.
Picking a consistent day each week and setting a phone reminder makes it easier to stay on track. You don’t need to inject at the same time of day each week, just the same day.
