Size of Tubes of Medicine

Today's note makes a practical point about the size of tubes of medicine. My goal is to help people and health care professionals correctly describe how much dermatologic medicine they have. Pictured right is a 100g tube of a medicine. Note this is 15 cm or 6 inches long.  Not pictured are sample sized tubes, which typically range in the 2g to 5g of medicine (about 1/8th oz.), and are about 2 inches or 5-6 cm long.  When people are prescribed 300g of medicine, often they receive three 100g tubes.  The mid-sized tubes are problematic to me, because they are 5 inches or 11 cm long, 3 cm wide, and usually contain 25-30g (1 oz.) of medicine.  Because of their length, they can be confused with the 100g tubes.
I hope this helps all.  This is not something to ask your Allergy Dude about.
