Compounding

So far I have had the opportunity to help compound several prescriptions during my APPE community rotation.  This has included utilizing geometric dilution to make a large quantity of topical cream and also to compound magic mouthwash. 

I also looked up expiration dates for non-sterile products which are as follows:

Beyond-Use Dating for Compounded Nonsterile Preparations

Temp	low risk single sterile components	medium risk use multiple sterile components	high risk use non-sterile components
room	48 hours	30 hours	24 hours
fridge	14 days	7 days	3 days
freezer	45 days	45 days	45 days

For oral aqueous refrigerated formulations the beyond use date is 14 days

For topical aqueous formulations the beyond use date is 30 days

For nonaqueous formulations the beyond use date is 6 months
