Informed Consent for Methoxyflurane Sedation

You should inform your dentist if you are taking any medications. Particular antibiotics can increase the risk of methoxyflurane to the kidneys. These medications include tetracycline, gentamicin, kanamycin, colistin, polymyxin B, cephaloridine and amphotericin B. Interaction with -blockers also exist, which may cause hypotension.

You should inform your dentist if you are pregnant or breastfeeding. Methoxyflurane can cross the placenta, and pose Central Nervous System and respiratory depression risks for compromised foetuses. Methoxyflurane can be passed to the baby through the breast milk.

If you have any of the above, you may still be able to use Methoxyflurane, but your dentist will need to assess the risks against the potential benefits.
