Understanding Semaglutide and Subcutaneous Injections
Let’s start by getting a handle on what semaglutide is exactly, and why where you inject matters.
What is Semaglutide:
Semaglutide is part of a class of medications called GLP-1 receptor agonists. It mimics a natural hormone in the body that regulates blood sugar levels and appetite, making it an effective tool for both diabetes management and weight loss.
Semaglutide is delivered via a subcutaneous injection, meaning it is injected into the fatty tissue just beneath the skin. This method allows for gradual absorption of the medication into the bloodstream, ensuring steady and prolonged action. It’s crucial to administer semaglutide in areas where subcutaneous fat is accessible and consistent to get the most out of the medication and achieve the results you want.
Why where you inject semaglutide matters:
Injecting too shallowly (into the dermis) or too deeply (into the muscle) can lead to inconsistent absorption. If the medication is not absorbed properly, it may not regulate blood sugar levels or appetite as intended, potentially diminishing its therapeutic effects. In addition, it can lead to some other unwanted effects like:
- Irritation and Discomfort: Injecting into areas with insufficient fat, such as bony or overly muscular regions, can cause more pain during and after the injection. Similarly, injecting into sensitive or compromised skin (e.g., scar tissue, bruises, or irritated areas) may lead to redness, swelling, or increased discomfort.
- Risk of Lipohypertrophy or Lipoatrophy: Repeated injections in the same spot can lead to fatty lumps under the skin. Conversely, repeated use of the same site can also lead to fat loss in that area, causing dents in the skin.
- Bruising or Bleeding: Injecting into areas with visible veins or insufficient fat can increase the likelihood of puncturing a blood vessel, leading to bruising or minor bleeding.
None of these are probably the hot look you’re going for, so let’s talk about how to do things the right way so you can inject like a pro and reap all of the benefits of semaglutide to achieve the look you want.
Primary Semaglutide Injection Sites
The body has several recommended areas for subcutaneous injections that will lead to stunning results. Each site has unique characteristics that may influence your choice:
The Abdomen
Why it’s ideal: The abdomen is often the preferred site for semaglutide injections due to its accessibility and the ample layer of subcutaneous fat. This area also provides consistent absorption rates.
How to choose the spot: Select a location below the ribs and at least 2 inches away from the navel to avoid scar tissue or sensitivity. Focus on the soft, fleshy part of the abdomen, avoiding areas too close to the sides where the skin may be thinner or over muscle. Avoid injecting into areas with stretch marks, scars, or bruises.
Tips: The abdomen offers a large surface area, making it easier to rotate injection sites within this region, reducing the risk of irritation or tissue damage.
The Thighs
Why it’s ideal: The front of the thighs, particularly the area midway between the knee and hip, provides a convenient alternative to the abdomen.
How to choose the spot: Look for a fleshy area with enough subcutaneous fat. Avoid bony areas or those close to joints. Stay away from the upper inner thigh as it’s more sensitive than the front of the thigh due to thinner skin and the presence of more nerve endings. Plus, this area is prone to rubbing and friction from clothing or during movement (e.g., walking or running), which can lead to irritation or soreness post-injection.
Tips: If you engage in regular physical activity, such as running, you may experience slight tenderness in the thighs after injection. Rotate injection points to avoid repeated use of the same spot.
The Upper Arms
Why it’s ideal: The outer part of the upper arm can be used, although it may be less convenient for self-administration.
How to choose the spot: Focus on the fleshy area on the back or side of the upper arm. You might need assistance from someone else to access this site. Steer clear of the deltoid. While it’s easier to access and great for vaccines, it doesn’t have enough fat to make it ideal for subcutaneous shots. You’ll likely end up injecting into the muscle, resulting in inconsistent absorption and diminished effects.
Tips: The upper arm is typically a secondary option and may not provide as much surface area for rotation compared to the abdomen or thighs.
The Importance of Rotating Semaglutide Injection Sites
Now that we’ve covered the best spots, we want to reiterate how important it is to rotate injection sites each time. As briefly mentioned before, repeated injections in the same spot can lead to tissue damage, irritation, lipohypertrophy, a condition where fatty lumps form under the skin, or lipoatrophy, a condition that causes fat loss resulting in dents under the skin.
These changes can affect how the medication is absorbed, reducing its effectiveness. Rotating injection sites helps prevent these issues. If you prefer using one area (e.g., the abdomen), ensure you move to a slightly different location each time.
Preparing for Your Injection
Proper preparation ensures both the safety and comfort of your injection experience:
1 – Cleanse the Area
Use an alcohol swab to thoroughly clean the injection site. This minimizes the risk of introducing bacteria under the skin.
2 – Prepare the Syringe
Ensure the semaglutide syringe is ready for use by confirm the dosage and check for air bubbles. Small bubbles are ok, and even relatively large ones don’t pose a threat for subcutaneous injections as the air is typically absorbed by the the subcutaneous tissue without complications. At YouthBar, we always pre-prime our syringes for our clients, but if you happen to find a bubble and are concerned here’s what to do:
- Draw the plunger back slightly to pull any liquid from the needle back into the syringe.
- Hold the syringe vertically so that the needle is pointed upwards and tap the syringe until the air bubble is at the top of the barrel.
- Slowly and gently push the plunger until the bubble is expelled and a small bead of the semaglutide forms at the opening of the needle. Be careful not to push so hard or quick that you loose some of the medication.
3 – Relax the Skin
Relax the muscles in the area to make the injection process smoother. If needed, gently pinch the skin to create a small pocket for the needle.
Administering the Injection
- Hold the semaglutide syringe at a 90-degree angle to your skin.
- Insert the needle fully into the fatty tissue. For individuals with less fat, pinching the skin can help.
- Slowly press down and hold the plunger on the syringe to release the medication. Keep the needle in place for the full count (5-10 seconds) to ensure complete delivery.
- Remove the needle gently and dispose of it immediately in a sharps container.
Post-Injection Care
After administering semaglutide, caring for the injection site helps maintain skin health and comfort:
- Monitor the Area: It’s normal to see slight redness or swelling immediately after the injection, which should subside quickly. Persistent swelling, pain, or signs of infection (e.g., warmth, pus) warrant a call to your healthcare provider.
- Massage (Optional): Some people find gentle massage of the injection site helps distribute the medication, but it’s not required.
- Stay Hydrated: Adequate hydration can support overall skin health and reduce discomfort.
