After 25 days of tb treatment and extended exposure to sun,ihave very itchy rash on most of my upper beck, chest and shoulders.shld i stop treatment?

TB Tx and sun: Do not stop your treatment. Many of the antibiotics used have a side effect of making you sensetive to the sun or can cause a rash if in the sun. Stay out of the sun, wear long sleeve shirt and hat or good sun block.

Not necessarily: What medications are you taking? Some can cause sun sensitivity. Is any other sun exposed skin, like the face, involved?
