Does taking metformin cause darkening of the facial skin?

Hello
Metformin does not list hyperpigmentation (darkening of the skin) as a side effect of this drug. But hormonal dysfunction can cause this, as can other medications. I will refer your question to a couple of DC friends I know because I note that quite a few people have asked this question on other site.
Take care

Hi, it is extremeley unlikely, as Emeraldgirl has stated, it is probably due to to another cause/another medication possibly. Birth control pills can cause this, would this be relevant to you? Latest statistics show: On Oct, 5, 2013: 88,866 people reported to have side effects when taking Metformin. Among them, 16 people (0.02%) have Skin Hyperpigmentation.

No it does not have that side effect.
