The small muscles in the hip that are commonly used for injections are the ventrogluteal or gluteus medius muscles, according to Scott & White Healthcare. These muscles are common sites for injections and can be used safely in people over 7 months of age. There is no maximum amount of medicine that can be injected at this site, and it is also recommended for intramuscular injections.
Intramuscular injections are shots of medicine given into the muscle. There are several types of injections that must be given this way, including those for medicines that need to take effect quickly and for medicines that cannot be taken orally, injected into a blood vessel or absorbed through the skin. The common sites for intramuscular injections include the thigh, top of the upper arm, hip and buttocks, notes Scott & White Healthcare.
A needle used for an intramuscular injection needs to be long enough to penetrate into the deep end of the muscle. Needles are measured by their length and gauge (diameter). The gauge of the needle should be 20 to 25. The length depends upon the size and age of the individual. Adverse reactions to intramuscular injections include side effects from the medicine or allergic reactions, rash, swelling or continued bleeding at the injection site, according to Scott & White Healthcare.
