A medicine delivery technique is a subcutaneous injection. Subcutaneous is a synonym for skin-deep. A small needle is used in this sort of injection to deliver a medicine into the tissue layer that lies between the skin and the muscle. When administered this method, medication is typically absorbed over a longer period of time—sometimes up to 24 hours—than if it were injected into a vein. When alternative routes of delivery may be ineffective, this kind of injection is employed. For instance, the stomach's acid and enzymes would destroy various drugs if they were taken orally. Other approaches, such as intravenous injection, can be time- and money-consuming. A subcutaneous injection can be a helpful, secure, and practical way to take medication for modest doses of delicate pharmaceuticals.
