[|Human|] It s getting darker and looks as if it could be getting bigger.There are no bumps. What could this be? Been going on for over a month- new meds taken Lipitor-20mg AND Nucynta er 100mg. I have NEVER had this before, only now- Need to know if theses meds might be the culprit(s)
[|AI|]  Hi, I assume you are talking about generalized skin darkening after initiating these medicines. Generally speaking, these medicines are not known to cause the side effects of skin pigmentation but if one is allergic to any of the component of these medicines (Lipitor & Junta) then it may be the result of allergy or reaction or a case of rare side effect. However, there may be other causes of skin darkening or pigmentation independent of these medicines which may need to be evaluated by a doctor after physical examination. Hope I have answered your query. Let me know if I can assist you further.
