What should I avoid while taking nitisinone?
Nitisinone is only part of a complete program of treatment that also includes a special diet.
It is very important to follow the diet plan created for you by your doctor or nutrition counselor. You
will need to avoid or restrict foods that contain tyrosine or phenylalanine.
Some of the foods that contain tyrosine include cheese, milk, sour cream, beer, wine, distilled
liquor, chicken, beef, liver, fish, processed meats (bologna, hot dogs, pepperoni, hard sausages), meat
tenderizer, herring or other dried fish, avocados, bananas, carrots, potatoes, oatmeal, brown rice, soy
sauce, spinach, tomatoes, bean curd, raisins, red plums, garbanzo beans, soy beans, and almonds.
Foods that contain phenylalanine include diet sodas, beef, poultry, pork, fish, milk, yougurt,
eggs, cheese, soybeans, soy protein, tofu, and certain nuts or seeds.
A major source of phenylalanine is the artificial sweetener aspartame (NutraSweet), which is
contained in many diet or sugar-free drinks and food products. Before consuming any packaged food
or beverage, carefully read the nutrition label to be sure the product does not contain phenylalanine or
have a warning about phenylketonuria.
There are other foods that may contain tyrosine or phenylalanine. Be sure you are familiar with
the list of foods you must avoid or restrict to help control your condition.
What other drugs will affect nitisinone?
There may be other drugs that can affect nitisinone. Tell your doctor about all the prescription
and over-the-counter medications you use. This includes vitamins, minerals, herbal products, and drugs
prescribed by other doctors. Do not start using a new medication without telling your doctor.
