HT-1 is a rare genetic disease affecting infants and children and the ones suffering from HT-1 face problems breaking down an amino acid called tyrosine.

"This new liquid formulation provides an additional option for parents with small children taking ORFADIN, or for anyone who has difficulty swallowing capsules."

This results in the formation and accumulation of toxic by-products in the body and can cause renal, liver and neurological problems, which can be fatal if untreated.

Orfadin blocks the breakdown of tyrosine and helps reduce the amount of toxic by-products in the body.

Available in a 4mg/mL dose, it should be used in combination with dietary restrictions of tyrosine and phenylalanine.
