However, the National Institute for Occupational Safety and Health Administration (NIOSH) recommends that no worker should be exposed at ceiling concentrations greater than 2 ppm of any halogenated anesthetic agent over a sampling period not to exceed one hour. The predicted effects of acute overexposure by inhalation of FORANE include headache, dizziness or (in extreme cases) unconsciousness. There are no documented adverse effects of chronic exposure to halogenated anesthetic vapors (W aste A nesthetic G ases or WAGs) in the workplace. Although results of some epidemiological studies suggest a link between exposure to halogenated anesthetics and increased health problems (particularly spontaneous abortion), the relationship is not conclusive. Since exposure to WAGs is one possible factor in the findings for these studies, operating room personnel, and pregnant women in particular, should minimize exposure. Precautions include adequate general ventilation in the operating room, the use of a well-designed and well-maintained scavenging system, work practices to minimize leaks and spills while the anesthetic agent is in use, and routine equipment maintenance to minimize leaks (See PRECAUTIONS). Store at room temperature 15°C-30°C (59°F-86°F). Isoflurane contains no additives and has been demonstrated to be stable at room temperature for periods in excess of five years.

Isoflurane is a clear, colorless, stable liquid containing no
additives or chemical
stabilizers. Isoflurane has a mildly pungent, musty, ethereal odor.
Samples stored in
indirect sunlight in clear, colorless glass for five years, as well as
samples directly
exposed for 30 hours to a 2 amp, 115 volt, 60 cycle long wave U.V.
light were
unchanged in composition as determined by gas chromatography.
Isoflurane in one
normal sodium methoxide-methanol solution, a strong base, for over six
months
consumed essentially no alkali, indicative of strong base stability.
Isoflurane does not
decompose in the presence of soda lime (at normal operating
temperatures), and does
not attack aluminum, tin, brass, iron or copper.
CLINICAL PHARMACOLOGY
Induction of and recovery from isoflurane anesthesia are rapid.
