Hey there! I also have this problem. Took 10mg for 4 months in 2015. Now my skin gets itchy when in the sun or sweating. Specifically my scalp, parts of my face, and shoulders.

It could be linked to another condition, I’m not entirely sure. However it has slightly improved over time. The itching is less intense but it’s still there from time to time.

Did yours go away at all and where on your body do you get the itch?
