Subcutaneous injections of insulin are typically rotated around the abdomen from the right upper quadrant, to the midepigastrium, left upper quadrant, left lower quadrant, hypogastrium, and right lower quadrant before returning to the right upper quadrant. A similar technique is used with low-molecular-weight heparins, colony-stimulating factors, and other drugs.
