Famprofazone, a nonsteroidal anti-inflammatory agent, is found in a multi-ingredient medication (Gewodin) used for pain relief. It is available over-the-counter in Taiwan. Famprofazone transforms to methamphetamine (MA) and amphetamine (AM) following administration, which is responsible for the side effects of the drug. For example, famprofazone user might be interpreted as an illicit MA abuser in Taiwan because the user's urine tested positive for MA.
