Sun exposure

While it is important for everyone to protect themselves from the effects of the sun, you will need to take even more care if you are on immunosuppressive drug treatments for your IBD. These include azathioprine, mercaptopurine and methotrexate, any of which will make your skin more sensitive to sun damage, and
may increase the risk of skin cancer.

You should use a high skin protection factor sunscreen (SPF 30 or above).
