Injections will always result in pain or minor discomfort in the IV site, but it's possible for the patient to feel tired and suffer a headache. The worst possible reactions include allergic reactions, blood clot formation, and kidney problems. As a professional, you should watch over your patient during the course of the injection administration for any adverse reactions.
