Subcutaneous injections are an alternative to intramuscular shots and maybe a less painful method for some patients, although they are less common. A subcutaneous injection uses a shorter needle to inject the solution into the tissue layer between the skin and muscle. Still, it may be a slower absorption rate than other administration methods. The best method depends on you, your need, and your comfort level with injections, and the subcutaneous method may be the most useful, safe, and convenient way for you.
