What are the side effects of taking anti-abuse for a long period?

The possible side effects of Antabuse (disulfiram) are numerous and too lengthy to list here. The most complete list I have located is available here: Drugs. com

Prior to beginning Antabuse it is essential that a Liver Function Test (LFT) be conducted as this drug interferes with alcohol metabolism in the liver and it's use is contraindicated where diminished liver capacity exists.

While rare (so it is stated*) liver damage can result from Antabuse even if liver damage was not present previously. Many physicians recommend monthly LFTs to guard against that result (I agree).

* while this drug has been in use since 1949 the overwhelming majority of research has been for the purpose of assessing effectiveness as a deterrent to drinking. Very little exists as to conditions that can result from the drug itself.

In what country do you reside? There seems to be a resurgence in use of Antabuse in some areas!
