Each week we will aim to bring out a concise email that provides 4-5 key pieces of information addressing a specific issue in clinical therapeutics.
This week: Finger-tip units
There can be some degree of confusion or doubt in regard to the amount of a topical product (cream or ointment) that needs to be applied to achieve an adequate therapeutic dosage in accordance with directions – one approach that can be used is to measure using the “finger-tip unit.”
- One fingertip unit (FTU) is the amount of cream or ointment, squeezed out of a tube, from the tip of an adult’s index finger to the first crease in the finger. One fingertip unit covers an area of skin twice the size of a flat adult hand (fingers together, not spread)
- To cover the face and neck of an adult, 2.5 FTUs are needed. The amounts will be larger to convert an arm + hand (4 FTUs), leg + foot (8 FTUs), chest + abdomen (7 FTUs) or back + buttocks (7 FTUs).
- Smaller amounts will be needed for children.
