Q

What unit of measurement can be used for topical medicines?

A

Fingertip unit

One FTU is the amount of topical steroid that is squeezed out from a standard tube along an adult’s fingertip. (This assumes the tube has a standard 5 mm nozzle.) A fingertip is from the very end of the finger to the first crease in the finger. One FTU is enough to treat an area of skin twice the size of the flat of an adult’s hand with the fingers together.
Two FTUs are about the same as 1 g of topical steroid. Therefore, for example, say you treat an area of skin the size of eight adult hands. You will need four FTUs for each dose. (This is 2 g per dose. If the dose is once a day, then a 30 g tube should last for about 15 days of treatment.)
