What is KUVAN?

KUVAN® (sapropterin dihydrochloride) Tablets for Oral Use and Powder for Oral Solution are prescription medicines used to lower blood Phe levels in people with a certain type of Phenylketonuria (PKU). KUVAN is to be used along with a Phe-restricted diet.

What is the most important information I should know about KUVAN?

    • Coughing
    • Feeling lightheaded or you faint
    • Feeling flushed
    • Nausea

    • Severe upper stomach-area (abdominal) discomfort or pain, nausea, and vomiting
    • Blood in your vomit or stool
    • Black, tarry stools
  • Phe levels that are too low—some children under the age of 7 who take high doses of KUVAN each day may experience low Phe levels
  • Too much or constant activity (hyperactivity) can happen with KUVAN. Tell your doctor if you have any signs of hyperactivity, including:
    • Fidgeting or moving around too much
    • Talking too much

What should I tell my doctor before I take KUVAN?
Before you take KUVAN, tell your doctor about all your medical conditions, including if you:

  • Are allergic to sapropterin dihydrochloride or any of the ingredients in KUVAN
  • Have poor nutrition or have a loss of appetite
  • Are pregnant or plan to become pregnant
  • Are breastfeeding or plan to breastfeed. It is not known if KUVAN passes into your breast milk. Talk to your doctor about the best way to feed your baby if you take KUVAN

Tell your doctor about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal and dietary supplements. KUVAN and other medicines may interact with each other. Especially tell your doctor if you take:

  • A medicine that contains levodopa
  • An antifolate medicine
  • Sildenafil (Revatio, Viagra), tadalafil (Adcirca, Cialis), vardenafil (Staxyn, Levitra)

Tell your doctor if you are not sure if your medicine is one that is listed above. Know the medicines you take. Keep a list of them to show your doctor and pharmacist when you get a new medicine.

How should I take KUVAN? See the detailed “Instructions for Use” that comes with KUVAN for information about the correct way to dissolve and take a dose of KUVAN tablets or KUVAN powder for oral solution.

  • It is not possible to know if KUVAN will work for you until you start taking KUVAN. Your doctor will check your blood Phe levels when you start taking KUVAN to see if the medicine is working
  • Take KUVAN exactly as your doctor tells you
  • You can swallow KUVAN tablets whole or dissolve the tablets in water or apple juice
  • KUVAN powder for oral solution should be dissolved in water or apple juice
  • Any change you make to your diet may affect your blood Phe level.

Even if you take KUVAN, if your blood Phe levels are not well controlled, you can develop severe neurologic problems
  • Your doctor should continue to monitor your blood Phe levels often during your treatment with KUVAN to make sure that your blood Phe levels are not too high or too low
  • If you have a fever, or if you are sick, your blood Phe level may go up. Tell your doctor as soon as possible so he or she can change your dose of KUVAN to help keep your blood Phe levels in the desired range
  • If you forget to take your dose of KUVAN, take it as soon as you remember that day. Do not take 2 doses in a day
  • If you take too much KUVAN, call your doctor for advice
