The degree of regulatory control afforded by Schedule F (prescription drug) status coincides 
with the risk factors associated with each medi cinal ingredient. Oversight by a practitioner is 
necessary to ensure that appropriate risk/benef it information is considered before the drug 
containing the medicinal ingredient is administ ered and that the drug therapy is properly 
monitored. 
Schedule F is a list of medicinal ingredients, th e sale of which is controlled under sections 
C.01.041 to C.01.049 of the Food and Drug Regulatio ns. Part I of Schedule F lists ingredients 
that require a prescription for human use and fo r veterinary use. Part II of Schedule F lists 
ingredients that require a prescription for hu man use, but do not require a prescription for 
veterinary use if so labelled or if  in a form unsuitable for human use.
