Occasionally skin rash, peripheral edema and abnormalities of serum transaminase have been reported.
Very rarely reported side effects include activation of peptic ulcer, hematemesis or melena, blood dyscrasia (in course of extensive usage). There have been isolated reports of anaphylactoid reactions.
