UCD Patient Videos

You may have a rare condition, but you're not alone.

Are you feeling that family and friends don't understand what it's like to live with a urea cycle disorder (UCD)? We can help you connect with patients and families who have been there. If you'd like to talk with another UCD patient or caregiver, sign up to speak with one of our UCD Mentors. Watch the videos below to learn from others living with urea cycle disorders. Learn about starting RAVICTI® (glycerol phenylbutyrate) Oral Liquid, how RAVICTI works, and how to take RAVICTI. There are also real life stories from UCD patients and caregivers and introductions to our UCD Mentors.

RAVICTI is for long-term management of high levels of ammonia in the blood (hyperammonemia) caused by a urea cycle disorder. RAVICTI must be used along with a low-protein diet and, in some cases, dietary supplements. RAVICTI should only be used if the UCD cannot be managed with a low-protein diet and dietary supplements alone. RAVICTI is not used to treat extremely high levels of ammonia in the blood (hyperammonemic crises) in people with UCDs as they may require rapidly acting medication. It is not known if RAVICTI is safe and effective for the treatment of N-acetylglutamate synthase (NAGS) deficiency.

Patricia & Isaac's Story

"I first learned that I had a urea cycle disorder when my son was diagnosed. For the first time, so many unanswered questions finally made sense." – Patricia
Experiences may not be typical. UCDs can manifest in different ways and at different times in a patient's life.

USE and IMPORTANT SAFETY INFORMATION

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

RAVICTI may cause serious side effects, including:

Nervous system side effects (Neurotoxicity) Phenylacetate (PAA), a breakdown product of RAVICTI, may cause nervous system side effects. Call your doctor or get medical help right away if you have any of these symptoms while taking RAVICTI:

  • sleepiness
  • lightheadedness
  • change in taste
  • problems with hearing
  • confusion
  • problems with memory
  • worsening of numbness, tingling, or burning in your hands or feet
  • headache
  • feeling very tired (fatigue)
  • nausea
  • vomiting

Your doctor may do blood tests to measure the amount of PAA in your blood during your treatment with RAVICTI.

David:

Before RAVICTI the medicine that they were taking was burdensome. I could not leave our house without a backpack. And that backpack, it had the medicine in it, but it also had everything I needed to prepare the medicine.

It formed our life. Everywhere we went, we’re connected to the medicine.

And it took a lot of time to prepare, and you had to measure and mix and there was so much of that.

So my life wasn’t revolving around what we were doing. Everything we did revolved around taking medicine.

Isaac:

My mom was taking the pills. I was taking the powder. It took me about 15 minutes per day just to take one round of medicine.

Patricia:

The other medication involved swallowing up to 39 pills a day. And I’m at work, and I’m in front of my students or my coworkers trying to down all these pills with my lunch.

Isaac:

The most challenging thing was definitely the taste. I’m glad that RAVICTI’s tasteless.

When I first started RAVICTI, I was, of course, nervous. But as I kept on taking it and taking it, I was noticing that it’s very convenient.

With the RAVICTI, all I gotta do is just measure out my dose, just take it. So it’s pretty easy for me to just take care of my own medication.

Patricia:

I know RAVICTI is not always going to work for everybody. But for myself my ammonia levels are well maintained.

David:

Not everyone is this way, but for us, RAVICTI made a huge difference. We have a small little pack we go out with.

Isaac:

It’s just a little bottle. You can either have a little carrying case or just even carry it in your pocket, as long as you’re careful. So, it is very convenient to just take wherever you need.

David:

They simply measure it, and they take it right there on the spot, and we move forward.
