Subcutaneous (Latin: Sub-: Lower, Cutis: Skin) is the term used in administering a subcutaneous injection. After that the substance will slowly be absorbed into the blood. A short needle is used which is placed in a fold in the skin that is made with the fingers. The abdomen is very suitable for this purpose. Examples of this are the administration of insulin by diabetics and the administration of methotrexate by people with rheumatoid arthritis. The volume of a subcutaneous injection should be less than 2.0 ml due to the risk of "leakage" to the outside.
