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.

Taking RAVICTI by Mouth

RAVICTI can be taken by mouth, even in patients with a feeding tube or g-tube.

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.\
