Who should not get a Dantrium IV injection?

A case of malignant hyperthermia can have potentially fatal complications if it is left untreated. Dantrium IV injections can be given to anyone, although you should make sure that your doctor is aware of every medical condition or allergy you have, as well as any medications you take, before you are anaesthetized. If you currently have allergies or an active liver disease (such as hepatitis or cirrhosis), your doctor will take extreme care deciding whether an injection of Dantrium IV is appropriate. Make sure to tell your doctor about liver or other medical conditions you have before you are anaesthetized, especially if you are over the age of 35. If you are pregnant or plan to become pregnant, consult your doctor immediately. Dantrium IV treatment falls into pregnancy category C, meaning that it is not known how the medication can affect a fetus. Doctors only administer Dantrium IV treatment if the benefits outweigh the potential risk to the fetus. Because Dantrium IV treatment may cause drowsiness, you should not drive until you know the effect of the medicine on your body.
