In the treatment of psoriasis, the most common adverse events are gastrointestinal events, flushing and lymphopenia, which are usually mild. Other adverse events include progressive multifocal leukoencephalopathy (PML) and Fanconi syndrome, which are considered rare. PML is probably caused by a combination of factors. A previous infection with the John-Cunningham virus (JCV) is considered a prerequisite for the development of PML. In a PML review, all confirmed cases were of patients exposed to periods of varying lymphopenia. For multiple sclerosis, adverse effects include flushing and gastrointestinal events, such as diarrhoea, nausea and upper abdominal pain. The drug label includes warnings about the risk of anaphylaxis and angio-oedema, PML, lymphopenia and liver damage.
