The Prescribing Information follows one of two formats: "physician labeling rule" format or "old" (non-PLR) format. For "old" format labeling a "product title" may be listed first and may include the proprietary name (if any), the nonproprietary name, dosage form(s), and other information about the product. The other sections are as follows: • Description - includes the proprietary name (if any),
nonproprietary name, dosage form(s), qualitative and/or quantitative ingredient information, the pharmacologic or therapeutic class of the drug, chemical name and structural formula of the drug, and if appropriate, other important chemical or physical information, such as physical constants, or pH. •
Clinical Pharmacology - tells how the medicine works in the body, how it is absorbed and eliminated, and what its effects are likely to be at various concentrations. May also contain results of various
clinical trials (studies) and/or explanations of the medication's effect on various populations (e.g. children, women, etc.). •
Indications and Usage - uses (indications) for which the drug has been FDA-approved (e.g. migraines, seizures, high blood pressure). Physicians legally can and often do prescribe medicines for purposes not listed in this section (so-called "
off-label uses"). •

not be used, for example in patients with other medical conditions such as kidney problems or allergies • Warnings - covers possible serious
side effects that may occur (e.g.,
