Injections are used to administer medications directly into the body, often for targeted treatment or rapid absorption.

They can be used for various purposes, such as vaccinations to prevent diseases, insulin injections for diabetes management, or pain relief injections like corticosteroids or anesthetics. Injections are also used in dermatology for cosmetic treatments like Botox or dermal fillers, and in orthopedics for joint injections to reduce inflammation or relieve pain.

Additionally, injections can deliver medications for chronic conditions, such as biologics for autoimmune diseases or osteoporosis treatments. They provide a precise and efficient way to deliver medications, often with faster results.
