Bulgaria

EMEA

The European Agency for the Evaluation of Medicinal Products has recommended the suspension of the marketing authorization for tolcapone. This follows several reports of severe and unpredictable hepatic reactions including fatal fulminant hepatitis. (Reference: Press release from the European Agency for the Evaluation of Medicines. 17 November 1998.)

Iceland

United Kingdom

November 1998

The manufacturer of the antiparkinsonism drug, tolcapone has voluntarily withdrawn it from the market.
