Hartnup disorder

Treatment:
  • Supplements containing nicotinamide are often the main treatment. This can effectively treat the rash, and can sometimes treat the uncoordination and psychiatric symptoms.
  • A high protein diet is recommended.
  • Avoiding sun exposure by wearing protective clothing and using a sunscreen of 15 factor or higher is recommended.
  • Psychiatric treatment, such as the use of antidepressants or mood stabilizers, may be needed if mood swings or psychiatric problems occur.


Expectations (prognosis):
Most people with this disorder can expect a normal lifespan with no disability. Rarely, there have been reports of severe bouts of neurologic disease and even deaths in families with this disorder.

Complications:
There are usually no complications. The minority of people who develop symptoms can experience rash, uncoordinated movements, and less frequently psychiatric symptoms.

Calling your health care provider:
Call for an appointment with your health care provider if you have symptoms suggestive of this condition, particularly if you have a family history of Hartnup disorder. Genetic counseling is recommended if you have a family history of this condition and are planning a pregnancy.
