Other information:

  • Acitretin must not be used if you are pregnant, or planning to become pregnant, because of a high risk of abnormalities in the developing baby. It is very important to use reliable contraception while taking acitretin and for 3 years after stopping. Talk with your doctor about your contraceptive options.
  • Tell your doctor if you are breastfeeding, or if you have high cholesterol or depression.
  • Sometimes psoriasis can get worse when you first start acitretin. Tell your doctor if this is troublesome.
  • Acitretin can make your skin sensitive, so avoid treatments such as waxing, laser or dermabrasion while taking acitretin and for 3 to 6 months after stopping.
  • Protect yourself from too much sunlight while being treated with acitretin. Always cover up and apply a thick layer of broad spectrum sunscreen (at least SPF 30) when outside. Do not use sunbeds.
  • You will need regular blood tests while taking acitretin to check if it is causing problems with your liver or cholesterol levels.
