Elevation of liver enzymes during treatment is a common side effect, but in rare cases there have also been reports of acute liver failure. Allergic reactions are also possible.

Rarely Albenza has been reported to cause marrow suppression, agranulocytosis or aplastic anemia which may be permanent.

Because of this dangerous side effect it is important to regularly monitor complete blood counts.
