If you have recently discovered you must inject yourself with medication or hormones on a frequent basis, then you may be a little nervous about how you’re going to feel about sticking yourself with a sharp needle. But the good news is that needles have come a long way – with the proper research, you can find the needle you need.
There are many types of needles and syringes that can be purchased today. Deciding what kind is best for you is an important decision and should not be taken lightly.
Hypodermic needles are the most commonly used needle. They are typically short and slender, and are used to inject drugs directly beneath the skin. Diabetics and people who are undergoing hormone replacement therapy or injecting other types of hormones will commonly use a hypodermic needle (by definition, hypodermic means “below skin”). Hypodermic needles are also used to inject drugs into the muscle, but those needles are typically longer and wider, and therefore sturdier so that they can pierce the muscle.
The terms “hypodermic needle” and “hypodermic syringe” are used almost interchangeably. Most of the time, the syringe and needle will be attached. The hollow needle is attached to a tube and a plunger. When the plunger handle is pulled back, medication is pulled into the tube. It is very important to keep the end of the needle in the fluid/medication when pulling the plunger. This will ensure that no air enters the tube. (Accidentally injecting an air bubble into a vein could result in serious health care problems.) Once the medication is drawn into the tube, then the needle is inserted into the skin, the plunger is pushed down, and the medication is effectively released into the body.
Hypodermic needles are also manufactured as stop needles, or safety needles. These types of needles have a device on them that prevents the needle from penetrating too deep into the skin.
In the past several years, contamination from shared needles has been a cause of concern in some large urban centers where illegal drug use is prevalent.
However, sterile needles are entirely safe to use. The federal government requires that needles are made from materials that are pharmacologically inert. They must also be able to be sterilized, although most of the time needles are used once and then thrown away. It’s very important to use proper disposal techniques for needles to prevent accidental needle sticks by another person.
