A year later, Dr Martin-Ortega and colleagues in Barcelona, Spain reported a case of "acneiform eruption" in a 54-year-old woman whose intake of amineptine was described as "excessive." One year after that, Vexiau and colleagues reported six women, one of whom never admitted to using amineptine, getting severe acne concentrated in the face, back and thorax

Mixed hepatitis, which is very rare, generally occurs between the 15th and 30th day of treatment. Often preceded by sometimes intense abdominal pains, nausea, vomiting or a rash, the jaundice is variable. Hepatitis is either of mixed type or with cholestatic prevalence. The evolution was, in all the cases, favorable to the discontinuation of the drug. The mechanism is discussed (immunoallergic and/or toxic).

In circa 1994 Spain, there was a case associating acute pancreatitis and mixed hepatitis, after three weeks of treatment.

Lazaros and colleagues at the Western Attica General Hospital in Athens, Greece reported two cases of drug induced hepatitis 18 and 15 days of treatment.
