6.Contents of the package and additional information

Ravicticontains the active ingredient «glycine phenylbutyrate», which is used to treat six «urea cycle disorders» (UCDs) known in adults, adolescents, and children. The UCDs include deficiencies of certain liver enzymes, such as carbamoyl phosphate synthetase I (CPS I),ornithine carbamoyltransferase (OTC), argininosuccinate synthetase (ASS), argininosuccinate lyase (ASL), arginase I (ARG), and ornithine translocase deficiency‑hyperammonemia-hyperornithinemia‑homocitrullinuria (HHH).

RAVICTI should be combined with a low-protein diet and, in some cases, with a diet supplemented with essential amino acids (arginine, citrulline, non-protein calorie supplements).

About urea cycle disorders

• In urea cycle disorders, the body is unable to eliminate excess nitrogen from the proteins we consume.
• Normally, the body converts excess nitrogen from proteins into a waste compound called «ammonia». The liver then eliminates ammonia from the body through a cycle called the «urea cycle».
• In urea cycle disorders, the body is not able to produce sufficient liver enzymes to eliminate excess nitrogen.
• As a result, ammonia accumulates in the body. If ammonia is not eliminated from the body, it can damage the brain and cause partial loss of knowledge or a coma.
• Urea cycle disorders are rare.

How Ravicti worksRavicti

Ravictihelps the body to eliminate waste nitrogen. This reduces the amount of ammonia in the body.

Do not takeRavicti

• if you are allergic toglycerol phenylbutyrate.
• if you have hyperammonemia (high levels of ammonia in the blood), which requires faster intervention (see the "Warnings and precautions" section.

If you are not sure if you are in any of the above circumstances, consult your doctor or pharmacist before takingRavicti.

Warnings and precautions

Consult your doctor or pharmacist before starting to takeRavicti:

• if you have liver or kidney problems, as RAVICTIis eliminated from the body through these
• if you have pancreas, stomach, or intestine problems, as these organs are responsible for the absorption of RAVICTI in the body.

If you are in any of the above circumstances, consult your doctor or pharmacist before takingRavicti.

In some cases,such as infection or postoperative, the amount of ammonia may increase despite treatment with glycerol phenylbutyrateand may damage the brain (hyperammonemic encephalopathy).

In other cases, the amount of ammonia in the blood increases rapidly. In this case, RAVICTI will not cause the amount of ammonia in the blood to increase to excessively high levels.

High levels of ammonia in the blood cause nausea, vomiting, or a feeling of confusion.

Inform your doctor or go to the hospital immediately if you notice any of these signs.

It will be necessary to perform analytical tests so that your doctor can determine and maintain the correct dose for you.

Other medications and RAVICTI

Inform your doctor or pharmacist if you are taking, have taken recently, or may need to take any other medication.

• midazolam and barbiturates (used for sedation, sleep problems, or epilepsy)
• contraceptives

Also, inform your doctor if you are taking any of the following medications, as they may increase the amount of ammonia in the body or change the functioning of RAVICTI:

• corticosteroids (used to treat inflamed areas of the body)
• valproic acid (a medication for epilepsy)
• haloperidol (used to treat some mental health problems)
• probencid (to treat high levels of uric acid in the blood, which can cause gout ["hyperuricemia"])
• lipase inhibitors (such as orlistat): used to treat obesity

Dose measurement

• Use an oral syringe to measure your dose.

1. Open the RAVICTI bottle by pressing the cap and turning it to the left.
2. 
   Place the tip of the oral syringe into the insertion piece of the syringe integrated into the bottle.

1. Hold the bottle down while keeping the oral syringe inserted.

1. Fill the oral syringeby pulling the plunger back until the syringe is filledwith the amount ofRAVICTIliquid that your doctor has indicated you should take.
   1. Nota: If possible, use the size of the oral syringe in milliliters that is closest to the recommended dose, without being less than this (for example, if the dose is 0.8ml, use an oral syringe of 1ml).

1. Give the oral syringe a tap to remove any air bubbles, making sure you have filled it with the correct amount of liquid.

1. Swallow the liquid from the oral syringe or connect the oral syringe to a gastrostomy tube or nasogastric tube.

1. Important note:Do not add Ravicti to large volumes of liquid or mix it with these, as RAVICTI is denser than most liquids. If you mix RAVICTI with large volumes of liquid, you may not get the full dose.
2. RAVICTI can be added to a small amount of soft food, such as ketchup, medical formulas, apple puree, orcarrot puree.
3. If the volume of the oral syringe is less than the prescribed dose, you will need to repeat these steps to get the full dose. Use an oral syringe for all doses taken each day.
4. After taking the full dose, drink a little water to make sure there is no medication left in your mouth, or rinse the nasogastric or gastrostomy tube with 10ml of water using a new oral syringe. The oral syringe used to rinse the nasogastric or gastrostomy tube should not be used to measure the RAVICTI dose, to avoid contact between the water and the medication.

1. Close the bottle by screwing the cap.

1. Important note:Do not rinse the oral syringe between daily doses, as the addition of water causes RAVICTI degradation. If RAVICTI comes into contact with water, the liquid will appear cloudy. Keep the bottle and oral syringe in a clean and dry place between doses.
2. Discard the oral syringe after the last dose of the day. Do not reuse the oral syringe to measure the RAVICTI dose another day.
3. Unused oral syringes should be kept to use with another bottle.Each bottle should be discarded after 14days.
