What happens if you inject something into your veins?
Arterial blood travels away from the heart so whatever is injected goes straight to body limbs and extremities. Injection particles get stuck in blood capillaries and cut off circulation. This can result in a lack of blood flow, eventually causing the tissue to die.
What happens if you give an intramuscular injection subcutaneously?
Subcutaneous injections can lead to localised cellulitis, granuloma formation and abscess. The COVID-19 vaccine has shown to have high efficacy if given correctly intramuscularly. Subcutaneous injection can happen inadvertently (figure 1), affecting efficacy of vaccination and potentiate local adverse events.
What is the difference between intramuscular and subcutaneous injections?
Intramuscular injections are absorbed faster than subcutaneous injections. This is because muscle tissue has a greater blood supply than the tissue just under the skin. Muscle tissue can also hold a larger volume of medication than subcutaneous tissue.
Can you inject into a blood vessel?
Intravenous injection (mainlining), or injecting a substance directly into the bloodstream through a vein, is one of the fastest ways to deliver a drug into your system.
When is a vein blown?
Blown veins occur when a needle injures or irritates a vein, causing blood to leak into the surrounding area. In some cases, IV fluid or medication may also leak from the vein.

Why are subcutaneous injections given at a 45 degree angle?
Insert the needle quickly at a 45- to 90-degree angle. Inserting quickly causes less pain to the patient. Subcutaneous tissue is abundant in well-nourished, well-hydrated people. For patients with little subcutaneous tissue, it is best to insert the needle at a 45-degree angle.
Where do you inject subcutaneously?
Subcutaneous tissue is all over your body, but the most common areas for subcutaneous injections are:
- the upper outer area of the arm.
- the front and outer sides of the thighs.
- the abdomen, except for a 2 inch area around the navel.
