Injectable medications are drugs that are delivered directly into the body using a syringe or needle. This method allows for quick absorption into the bloodstream, making it effective for treating various medical conditions. Common types of injectable medications include vaccines, insulin for diabetes, and antibiotics for infections. There are different routes for administering injectable medications, such as intramuscular, subcutaneous, and intravenous. Each route has specific uses and benefits, depending on the medication and the patient's needs. Proper training and techniques are essential for healthcare providers to ensure safe and effective administration of these medications.
