The Ontario College of Pharmacists is implementing new guidelines for compounding that requires much tougher criteria to be able to compound Rxs, including making separate and physically distinct rooms for hazardous and non-hazardous prescriptions, and installing expensive ventilation hoods for each of these rooms. Also, the HVAC system must be adjusted to send all the fumes from these compounds to the roof of the building housing the pharmacy. Most of the smaller pharmacies will not accommodate for such criteria as they lack the physical space and would not financially make sense for them to spend the amounts needed to compound a few Rxs per year.
