Off-label use

Prescribing an approved drug for a condition, dose, or age group the FDA never approved it for — legal for doctors, illegal for manufacturers to promote.

Your prescriber writing an off-label prescription may be practicing good medicine. a company marketing that prescription has, more than once, been committing a crime. both halves are worth understanding.

What it is

When the FDA approves a drug, it approves specific uses — the indications on its label. Prescribing outside them is off-label: a different condition, age group, or dose. Off-label prescribing is legal, common, and sometimes well supported by evidence the label never caught up with.

Where the money in drug litigation comes from

Manufacturers promoting off-label uses is illegal, and that line produced the largest health-care-fraud settlements in US history — gabapentin promoted for a list of unapproved uses, olanzapine and quetiapine and risperidone in elderly dementia patients, paroxetine and Wellbutrin in GSK's criminal plea. The asymmetry is the point: the same prescription can be good medicine from a doctor and a felony from a marketing department.
