Injections are part of modern medical practice.
They are useful if a patient cannot swallow or a very quick action is needed. Some medicines have to be given by injection because they are not absorbed by the gut. Most vaccinations have to be given by injection. Injections are not necessarily more powerful than tablets. People usually prefer taking medicine by mouth and this avoids the pain and the risks of the injection itself.
