Final answer:
A prescriber can prohibit generic substitution on a verbal prescription by specifying the brand name of the medication instead of its generic name.
Step-by-step explanation:
In certain circumstances, a prescriber may choose to prohibit generic substitution on a verbal prescription. This can be done by specifying the brand name of the medication rather than its generic name. For example, instead of prescribing 'ibuprofen,' the prescriber may specifically state 'Motrin,' which is a brand name of ibuprofen. By doing this, the prescriber ensures that only the specific brand they have prescribed will be dispensed, without any substitutions.
It is important to note that this option may not be available for all medications. Some drugs may not have specific brand names or the prescribing guidelines of certain healthcare systems or insurance plans may not allow for brand name prescriptions. Additionally, a prescriber should consider the cost implications of directly prohibiting generic substitutions, as brand name drugs are often more expensive than their generic counterparts.
