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.

Amy:

Mya was diagnosed at 6 months old. Our first step was low-protein diet. And she was just on that until about a year. At a year, we added some supplements. At 2 years, we had to add a medication, an ammonia scavenger.

The ammonia scavenger she was on could leave a bad taste in the mouth.

It was challenging to just flat out get her to take it.

And I thought there has to be another treatment. I was willing to try something new.

So I went to the Internet, and I searched and I searched, and I found RAVICTI. And I thought, I have to get my child on this.

I did talk to my doctor about starting RAVICTI.

I had found most of the information online, so I pretty much sent him a link and said, "Here's this information." And he responded, "Great. I support you." RAVICTI may not be a fit for everybody. For Mya specifically, it is convenient because it’s tasteless, it’s odorless. Mya really doesn’t mind taking it.

For us, starting RAVICTI was pretty easy.

It was easy for her to take and the routine was the same, cause she still got the RAVICTI at the same time every day that she got the other one. It was just a different medication.

Every family’s experience is different, but for us Mya has been on RAVICTI for almost 6 years and we continue to like the convenience.

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.

Amy:

It took me a few times, but now I’m that hospital mom momma bear. …After the lab techs come up, and they poke her twice…I’m the mom that’s not afraid to ask for the anesthesiologist because…if they waste 6 different poke sites, just trying to start one IV, we’re gonna be in trouble for that whole hospitalization.

And I had had different experiences with doctors and hospitals, so I knew right away that if you walk in and you act like you own the meeting, you own the meeting. And that’s what I did.

You have to be aware of what’s going on. And you know your child best.

David:

Thank God for doctors.

…They’re trying to do their best to serve you… So you have to treat them well. But at the same time you have to be an advocate when you present to a, ah, an emergency room or a medical situation with your child.

You won't get it from yelling. Don’t do anything like that. Just persistently be an advocate for your child.

You have to do it as a parent, and we’ve been teaching our son, to be his own advocate.

Do it sternly, firmly, consistently. Do not back down. If you do not get results, find somewhere where you can.

Advocating for Your Child

“As the mother of a child with a rare disease, you have to find your own voice, and use it.”

How RAVICTI Works

how-ravicti-works
Read transcript

Hello, today I want to talk to you about Understanding Urea Cycle Disorders and Your RAVICTI Treatment. First, let's talk about Urea Cycle Disorders. What is a Urea Cycle Disorder?

A urea cycle disorder, or UCD, is a rare inherited condition where toxic levels of waste called ammonia build up in the blood and cause damage throughout the body.

Ammonia is released when the body digests protein from food.

Normally, the liver makes enzymes that break down the ammonia into urea. The body then gets rid of urea through urine.

In people with a UCD, these enzymes don’t work right, so ammonia builds up in the blood.

High levels of ammonia in the blood can make you very sick and cause serious health problems. A low-protein diet and supplements can help keep ammonia levels down, but sometimes this isn’t enough.

Adding RAVICTI can help keep ammonia at a safe level in the blood.

RAVICTI is slowly broken down by a naturally-occurring enzyme found in the digestive tract.

RAVICTI passes through the stomach and starts to slowly break down in the intestine. Once it breaks down, it can start getting to work.

A part of RAVICTI then binds to ammonia molecules to form a RAVICTI/ammonia complex that is excreted in the urine.

When taken correctly, RAVICTI works to keep removing extra ammonia throughout the entire day. RAVICTI may cause side effects. The most common side effects of RAVICTI in adults include: diarrhea, gas, headache, abdomen (stomach) pain, vomiting, tiredness, decreased appetite, indigestion or heartburn.

So how do you take RAVICTI? RAVICTI is a liquid that you take by mouth with a syringe or dosing cup 3 or more times a day with a low-protein diet and in some cases dietary supplements.

It’s important to take RAVICTI exactly as your doctor tells you in order to keep the ammonia in your body at a safe level.

Set reminders so you don’t forget to take your dose...and keep track of when you do take it.

A UCD is a lifelong disease that can cause organ damageand other very serious health problems over time without proper treatment. So even if you’re feeling fine, it’s important to continue taking your Ravicti to help prevent toxic buildup of ammonia in the blood. Talk to your doctor for more information and to help create a routine that works for you.

Read transcript

Welcome to the RAVICTI (glycerol phenylbutyrate) Oral Liquid instructional dosing video.

In this video you will see step-by-step instructions for the oral administration of RAVICTI for you or your child.

This video is intended to complement the instructions you have already received from your doctor. Always take RAVICTI exactly as directed by your doctor. 

Do not mix RAVICTI with formula or any other liquids.

Now, let’s get started. 

Your RAVICTI shipment includes 

a 25-milliliter bottle of RAVICTI, a reclosable bottle cap adapter, and an oral syringe.

When dosing RAVICTI, be sure to use the oral syringe provided with the product.

First, remove the childproof cap on the RAVICTI bottle. To do that, push down on the cap while twisting it to the left. 

Then, attach the reclosable bottle cap adapter onto the bottle. Put it on top of the bottle and twist it to the right.

Make sure it is secured tightly on the bottle.

While holding the RAVICTI bottle securely, place the tip of the oral syringe into the reclosable bottle cap adapter. 

Turn the bottle upside down with the oral syringe still inserted. 

Now you’re ready to fill the oral syringe with RAVICTI.

Withdraw the prescribed dose of RAVICTI with the dry oral syringe by pulling the plunger back.

Pull the plunger back until the first line of the black rubber stopper is even with the dosing mark. The dosing marks are on the barrel of the oral syringe. Match the dosing mark with the amount of medicine prescribed by your doctor. 

Then, turn the bottle upright again.

If there are large air bubbles, push the medicine back into the bottle.  Do this slowly. 

Then draw up the medicine again.

Once you have your oral syringe ready, place it into the mouth. Push the plunger to squirt the medicine directly into the mouth.  

Make sure all of the medicine is pushed out of the oral syringe and swallowed. 

Put the cap on the oral syringe. 

Drink liquid or eat some food right after taking RAVICTI. 

This helps ensure that all of the medicine is swallowed.

Close the tab on the reclosable bottle cap adapter. 

Make sure it’s closed tightly. 

After the last dose of the day, dispose of the oral syringe.  

Take the exact amount of RAVICTI Oral Liquid as instructed by your doctor.

Your doctor may change your dose if needed.

Take RAVICTI with food or formula.

In an infant who is breastfeeding, give RAVICTI just prior to breastfeeding.

Use a new reclosable bottle cap adapter with each new bottle of RAVICTI that is opened.

Use a new dry oral syringe to withdraw each prescribed dose of RAVICTI.

If you take too much RAVICTI, call your doctor or the Poison Control Center at 1-800-222-1222 or go to the nearest hospital emergency room right away.

Do not stop taking RAVICTI unless your doctor tells you to stop. 

If you miss a dose of RAVICTI, take it as soon as possible.

Do not take 2 doses of RAVICTI at the same time.

If you miss more than 1 dose and are not feeling well, call your doctor or nurse right away.  

If you still have questions about how to take RAVICTI with an oral syringe, please contact your doctor for more information.

If RAVICTI is in contact with water, it will become cloudy in appearance. If the contents are in contact with water or cloudy, then do not use the remaining RAVICTI and contact your prescribing doctor or pharmacy. 

Discard bottle and any remaining contents 28 days after opening. 

Ask your pharmacist for oral syringes and a reclosable bottle cap adapter for each bottle you receive if you do not have them.\

Read transcript

Welcome to the RAVICTI (glycerol phenylbutyrate) Oral Liquid instructional dosing video. 

In this video, you will see step-by-step instructions for administration of RAVICTI if you or your child have a nasogastric or gastrostomy feeding tube.

If you can swallow liquids, it is recommended you take RAVICTI by mouth.

This video is intended to complement the instructions you have already received from your doctor. Always take RAVICTI exactly as directed by your doctor. 

Do not mix RAVICTI with formula or any other liquids.

Now, let’s get started.

Your RAVICTI shipment includes: 

a 25-milliliter bottle of RAVICTI, a reclosable bottle cap adapter, and an oral syringe.

When dosing RAVICTI, be sure to use a new dry oral syringe. 

First, remove the childproof cap on the RAVICTI bottle.  To do that, push down on the cap while twisting it to the left. 

Then, attach the reclosable bottle cap adapter onto the bottle.  Put it on top of the bottle and twist it to the right.

Make sure it is secured tightly on the bottle.

While holding the RAVICTI bottle securely, place the tip of the oral syringe into the reclosable bottle cap adapter. 

Turn the bottle upside down with the oral syringe still inserted. 

Now you’re ready to fill the oral syringe with RAVICTI.

Withdraw the prescribed dose of RAVICTI with the dry oral syringe by pulling the plunger back.

Pull the plunger back until the first line of the black rubber stopper is even with the dosing mark. The dosing marks are on the barrel of the oral dosing syringe. Match the dosing mark with the amount of medicine prescribed by your doctor.

Then, turn the bottle upright again.

If there are large air bubbles, push the medicine back into the bottle. Do this slowly.

Then draw up the medicine again.

Next, place the tip of the oral syringe into the smaller port of the feeding tube.

The smaller port of the nasogastric or gastrostomy feeding tube is used for medicine.

Ask your doctor if you are not sure which port to use. 

Using the plunger of the oral dosing syringe, slowly and carefully push RAVICTI into the feeding tube. 

Make sure all of the medicine is pushed out of the oral dosing syringe.

After you have pushed all of the RAVICTI into the feeding tube, remove the oral syringe, put the cap on the oral syringe, and set it aside.

Close the tab on the reclosable bottle cap adapter.

Make sure it’s closed tightly. 

Use a separate large syringe to flush water into the feeding tube. A large syringe can be found in the box containing your feeding tube.

Make sure all of the water or formula drains through the feeding tube. 

For patients who have a nasogastric tube or gastrostomy tube in place, give RAVICTI as follows:

  • Use an oral syringe to withdraw the prescribed dosage of RAVICTI from the bottle.
  • Place the tip of the syringe into the tip of the gastrostomy/nasogastric tube.
  • Using the plunger of the syringe, push RAVICTI into the tube.
  • Flush once with 10 mL of water or formula and allow the flush to drain.
  • If needed, flush a second time with an additional 10 mL of water or formula to clear the tube.

You can use 1 oral syringe and 1 reclosable bottle cap adapter for all doses each day. 

You can also choose to use a new oral syringe with each dose. 

Do not rinse the reclosable bottle cap adapter or oral syringe between doses. 

After the last dose of the day, dispose of the oral syringe.  

Take the exact amount of RAVICTI Oral Liquid as instructed by your doctor.

Your doctor may change your dose if needed.

Take RAVICTI with food or formula.

In an infant who is breastfeeding, give RAVICTI just prior to breastfeeding.

Use a new reclosable bottle cap adapter with each new bottle of RAVICTI that is opened.

Use a new dry oral syringe to withdraw each prescribed dose of RAVICTI.

If you take too much RAVICTI, call your doctor or the Poison Control Center at 1-800-222-1222 or go to the nearest hospital emergency room right away. 

Do not stop taking RAVICTI unless your doctor tells you to stop.

If you miss a dose of RAVICTI, take it as soon as possible.

Do not take 2 doses of RAVICTI at the same time.

If you miss more than 1 dose and are not feeling well, call your doctor or nurse right away.

If you still have questions about how to take RAVICTI with an oral syringe, please contact your doctor for more information.

1. For patients who require a volume of less than 1 mL per dose via nasogastric or gastrostomy tube, the delivered dosage may be less than anticipated due to adherence of RAVICTI to the plastic tubing. Therefore, these patients should be closely monitored using ammonia levels following initiation of RAVICTI dosing or dosage adjustments. 

If RAVICTI is in contact with water, it will become cloudy in appearance. 

If the contents are in contact with water or cloudy, then do not use  the remaining RAVICTI and contact your prescribing doctor or pharmacy.

Discard bottle and any remaining contents 28 days after opening. 

Ask your pharmacist for oral syringes and a reclosable bottle cap adapter for each bottle you receive if you do not have them.
