[Probable side effects caused by plethoryl. Common acute hepatitis, anicteric hepatitis, cirrhosis due to hypervitaminosis A, inflammatory arthralgias].

Plethoryl is a combination of triatricol, cyclovalone and vitamin A normally prescribed in the treatment of hypercholesterolaemia. Four cases of side-effects most probably caused by this product are reported. They include: 1) a case of common acute hepatitis, 23 cases of which have already been published, with aggravation and reduced time-lapse after reintroduction; 2) a case of clinically silent but biochemically classical hepatitis; 3) a case of cirrhosis due to vitamin A toxicity; 4) a case of inflammatory arthralgias recurring after the same time-lag when the drug was reintroduced despite double doses and without clinical evidence of hepatitis. The last three side-effects have never been previously reported. The adverse reactions to Plethoryl almost always occur in the unofficial indications of the product, notably in the "treatment" of obesity.
