10 Causes and Symptoms of Folliculitis

7. Drugs:

Several drugs are known to be associated with folliculitis eruptions. These drugs can be systemically administered or topically applied to the skin. The most types of drugs that are known to cause folliculitis include steroids (such as androgens), oral contraceptives, halogens, lithium, immunosuppressants, epidermal growth factor receptor inhibitor, and anticonvulsants. The overuse of these drugs and medicines can cause damage to the immune system and hair follicles leading to folliculitis. However, the symptoms are not as severe as other causes. And the condition can most often be controlled (and alleviated) by simply reducing the intake of the drug.
