10 Things You Didn’t Know About Lichen Planus
2. Gold Injections

One type of medicine responsible for triggering lichen planus in some instances belongs to a group called gold injections. They are used for people with diabetes to help reduce pain in joints, minimize inflammation, prevent further damage to joints, and help maintain what is left of deteriorating joints. These disease-modifying antirheumatic drugs (DMARDS) are issued through injection into the muscles.
1. Cause

The rash, lichen planus has no known cause but can show up following the consumption of some medicines, such as thiazide diuretics, antimalarial pills, and tranquilizing drugs called phenothiazines. There are other schools of thought, particularly among dermatologists, which believe the condition is an autoimmune reaction. This outcome can happen when too many antibodies are produced by the immune system in an attempt to fight infection, resulting in inflammation of the skin.
