Here's part of another article that I'd found at http://www.aafp.org/afp/20000601/3319.html
While most cases of lichen planus are idiopathic, some are linked to medication use or hepatitis C virus (HCV) infection. Lichenoid drug eruptions are reactions that may occur after exposure to various medications. These eruptions may exhibit a cutaneous and histologic appearance identical to that of idiopathic lichen planus and, thus, must be considered in every patient with lichen planus. While an exhaustive list of possible offending agents is quite long, the most common include gold, antimalarial agents, penicillamine, thiazide diuretics, beta blockers,7 nonsteroidal anti-inflammatory drugs, quinidine and angiotensin-converting enzyme inhibitors.8 The interval between administration of the offending medication and the development of the lichenoid drug eruptions is usually a few months, although it may range from 10 days to several years.8 While the eruptions spontaneously clear anywhere from weeks to months after discontinuation of the medication in many patients, some patients require systemic therapy. -- The Silver List is a moderated forum for discussing Colloidal Silver.
