Ozempic injection sites and pen use

Ozempic injection sites

The label names three areas, each injected under the skin: the stomach area (abdomen), the thigh and the upper arm.¹ Ozempic is not injected into a muscle or a vein.¹ The label's pharmacology section reports similar semaglutide exposure from all three areas, and the label does not rank one above another.¹ The instructions for the single-dose syringe add detail: the stomach area at least 2 inches from the belly button, the thighs, or the back of the upper arm, only with help from someone else.¹

Patient guides from the U.S. National Library of Medicine describe the same areas in more detail, for prescribed injections under the skin in general:

• Belly: below the ribs and above the hip bones, at least 2 inches (5.1 cm) from the belly button.²
• Upper arm: the side or back, at least 3 inches (7.6 cm) below the shoulder and 3 inches above the elbow.²
• Thigh: the outer side of the upper thigh.²

The skin chosen should be healthy, with no redness, swelling, scarring or bruising.² The MedlinePlus insulin guide adds a 1 inch (2.5 cm) gap from scars and says to skip spots that are bruised, tender, lumpy, firm or numb.³ When Ozempic and insulin are both used, the label says to give them as separate injections and never mix them; they can go in the same body area, but not right next to each other.¹

Rotating the site

The label says to rotate the site with each injection; when the same body region is used, a different spot is chosen each week.¹ The NHS frames it the same way for weekly semaglutide: the same area is fine, but not the exact same spot.⁴ MedlinePlus suggests keeping injections at least 1 inch apart and keeping a chart of the spots already used.²³

How the pen is used

The Instructions for Use describe these steps for each injection:¹

1. Prepare the pen. Hands are washed with soap and water, and the pen's name and colored label are checked to confirm it holds Ozempic. The medicine in the pen window should be clear and colorless; a pen that looks cloudy or has particles is not used.¹
2. Attach a new needle. A new needle is used for every injection; NovoFine Plus 32G 4 mm needles come with the pen.¹
3. Flow check, new pens only. Before the first injection with each new pen, the dose selector is turned to the flow check symbol, the pen is held needle up, and the button is pressed until the counter shows 0. A drop should appear at the needle tip.¹
4. Select the dose. The dose selector is turned to the prescribed dose.¹
5. Inject and hold. The chosen site is wiped with an alcohol swab and left to dry. The needle goes in, and the dose button is pressed and held until the counter shows 0. The button stays pressed for a count of 6 seconds before the needle comes out; removing it early can mean the full dose is not delivered. If blood appears, the site is pressed lightly with gauze or a cotton ball, not rubbed.¹
6. Remove the needle. The needle comes off after every injection and goes into a sharps disposal container, and the pen is stored without a needle attached.¹

An Ozempic pen is never shared, even if the needle is changed, because sharing can spread blood-borne infections.¹ FDA, which has found counterfeit Ozempic 1 mg pens in the U.S. supply chain, tells patients to get Ozempic only with a valid prescription through state-licensed pharmacies and to check the product for signs of counterfeiting before use.⁸

Nothing to reconstitute

Ozempic comes as a clear, colorless solution in a prefilled pen or a prefilled syringe, and the label has no mixing or reconstitution step.¹ The Instructions for Use say never to use a syringe to draw Ozempic out of the pen.¹ Besides semaglutide, each milliliter of the pen solution holds disodium phosphate dihydrate (1.42 mg), propylene glycol (14 mg), phenol (5.5 mg) and water for injections, at a pH of about 7.4.¹ The single-dose syringes use sodium chloride in place of propylene glycol and phenol.¹

Storing pens and syringes

A pen that has been frozen is not used, and pens are not left in a car or anywhere they can get too hot or too cold.¹

Getting rid of used needles

FDA counts needles, syringes and auto-injector pens as sharps, and says sharps thrown away unsafely can injure people and spread infections, most often hepatitis B, hepatitis C and HIV.⁵ Its advice has two steps: put needles in a sharps disposal container right after use, then get rid of the full container according to community rules.⁶

• FDA says to follow those rules when the container is about three-quarters full, because overfilling raises the risk of a needle-stick injury, and not to reuse the container.⁶
• If an FDA-cleared container is not at hand, a heavy-duty plastic household container, such as a laundry detergent bottle, can be used if it is leak-resistant, stays upright and has a tight-fitting, puncture-resistant lid. It should be labeled to warn of hazardous waste inside.⁵¹⁰
• Loose needles never go in household or public trash or recycling bins, and are never flushed down the toilet.⁵⁷
• Options depend on where a person lives: drop boxes or supervised collection sites such as pharmacies and hospitals, household hazardous waste sites, mail-back programs and residential pick-up.⁶
• Sharps and their containers are kept out of reach of children and pets.⁶

If someone is stuck by another person's used needle, FDA says to wash the area right away with soap and water or an antiseptic such as rubbing alcohol or hand sanitizer, and to get medical attention right away.⁵

The Ozempic pill is not injected

Ozempic tablets are swallowed once a day, so none of these injection steps apply to them.⁹ Their daily schedule is in Ozempic dosage.
