Fat Emulsion (intravenous)

Fat emulsions are used to help patients build fat in their body following a recent surgery or illness.


Fat emulsions are used to supplement the diet of patients who are unable to get enough fat from a normal diet. This can occur as a result of a recent surgery or following certain illnesses.

The body needs to have fat because it is used as an energy source and in the creation of substances required for normal bodily functions to take place.

Fat emulsions are injected into the veins of the patient and are available only with a prescription from a doctor. They are prescribed as Clinolipid or Liosyn injections.
