Pregnancy Category C. Isoflurane has been shown to have a possible anesthetic-related fetotoxic effect in mice when given in doses 6 times the human dose. There are no adequate and well-controlled studies in pregnant women. Isoflurane should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
Nursing Mothers: It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when Isoflurane is administered to a nursing woman.
Perioperative hyperkalaemia; raised intracranial pressure. May impair ability to drive or operate machinery. Pregnancy and lactation. Do not allow carbon dioxide absorbents in anaesthetic apparatus to dry out when delivering isoflurane to minimise the risk of developing elevated carboxyhaemoglobin levels.
General (Inhalation) anesthetics
Store at room temperature 15°-30°C. Isoflurane contains no additives and has been demonstrated to be stable at room temperature for periods in excess of five years.
