If you have a chronic disease, your doctor may prescribe injectable medications instead of oral medications. This allows the drug to be absorbed directly into the bloodstream, which has a faster onset than oral drugs. Certain injectable drugs are formulated to slowly release their active ingredients over time rather than all at once.
Injection can be done in a variety of ways. How to inject drugs depends on many factors, including:
- How the medicine is made
- How fast the drug works
- Injection volume

You can administer many injections yourself at home, but some require a medical professional to administer injections in your home or office. If you have any questions about how to use the medicine, please consult your doctor or pharmacist before the injection.
