Injection

Injection refers to a medical procedure where a substance, such as medication or vaccine, is introduced into the body using a needle and syringe. This method allows the substance to reach the bloodstream or tissues directly, ensuring quicker and more effective results compared to other forms like pills. Injections can be given in various ways—intravenous (into a vein), intramuscular (into a muscle), or subcutaneous (under the skin)—depending on the treatment. Proper technique and sterile conditions are essential to prevent infections and ensure safety.
