  • And alterations of the skull and cervical vertebrae
• Acitretin should not be used by women who are breastfeeding because acitretin can pass intobreast milkand harm the infant.

• Combining acitretin with alcohol increases the formation of etretinate. Etretinate remains in the body for a longer period than acitretin and it is very harmful to a fetus.
