Certain medicines come prepared in injection pens. The injection pen makes giving injections much easier. The companies that make each pen offer directions on their use.
You can also find injection aides such as magnifiers that help a person see the numbers on the side of the syringe.
These are available in medical equipment stores and some drug stores.
Because subcutaneous tissue is sensitive to pain, it is normal for an injection to cause mild discomfort. However, the needles used for a subcutaneous injection are very small and thus pain is minimal.
A medicine will absorb and have its best effects when you give a subcutaneous injection correctly.
