One thing to watch out for is that Cypress makes two forumlations of 1.1 Flouride. There is the SF 1.1% GEL that is perfect for flouride trays and the SF 5000 Plus which does not work well in trays. While both are 1.1% flouride prescriptions, the SF 5000 is subtitle "prescription Dental Cream" while the Gel is subtitled " Prescription Gel". My pharmacy simply could not get it right because their computer brought either one up as exactly the same. They had to special order the Gel but now they understand.
