How much cream is needed for your dermatology patient? For scabies, one treatment requires about 1 oz (30 gm) for an adult, and ½ oz (15 gm) for a child. Since it is recommended to repeat the treatment in 1-2 weeks, prescribe 2 oz for adults/teens and 1 oz for children. Another useful measure is the Fingertip Unit (FTU). It is the amount of cream squeezed out from a standard 5mm nozzle from the tip of the patient’s index finger to the first crease (DIP joint). Standard FTU doses required for one application to various parts of the body are as follows: 

Head (front and back)
Arm
Foot
Leg
Face and Neck
Torso (front OR back)
Entire body
1 FTU
3 FTU
2 FTU
6 FTU
2.5 FTU
7 FTU
40 FTU
