RAVICTI 1.1 G/ML ORAL LIQUID

2. What you need to know before you take RAVICTI

Do not takeRavicti

• if you are allergic to glycerol phenylbutyrate.
• if you have hyperammonemia (high levels of ammonia in the blood) that requires more rapid intervention (see the section "Warnings and precautions").

If you are unsure whether you are in any of the above situations, consult your doctor or pharmacist before taking Ravicti.

Warnings and precautions

Consult your doctor or pharmacist before starting to take Ravicti:

• if you have liver or kidney problems, as RAVICTI is eliminated from the body through these organs.
• 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 situations, consult your doctor or pharmacist before taking Ravicti.

In some cases, such as infection or post-operative, the amount of ammonia may increase despite treatment with glycerol phenylbutyrate and may damage the brain (hyperammonemic encephalopathy).

In other cases, the amount of ammonia in the blood may increase 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.

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

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

Other medicines and RAVICTI

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.

In particular, tell your doctor or pharmacist if you are taking any of the following medicines, which may be less effective when used with RAVICTI. If you are taking these medicines, you may need to have regular blood tests:

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

Also, tell your doctor if you are taking any of the following medicines, as they may increase the amount of ammonia in the body or change the way RAVICTI works:

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

If you are in any of the above situations (or are unsure), consult your doctor before taking Ravicti.

Pregnancy, contraception, and breastfeeding

• If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor before using Ravicti. If you become pregnant during treatment with Ravicti, consult your doctor. RAVICTI should not be used during pregnancy, as the risks to the fetus cannot be ruled out.
• If you are a woman who can become pregnant, you must use an effective contraceptive method during treatment with Ravicti. Consult your doctor about which contraceptive method is best for you.
• If you plan to breastfeed while taking RAVICTI, you should talk to your doctor. It will be necessary to decide whether to stop breastfeeding or stop treatment, considering the benefit of breastfeeding for the child and the benefit of treatment for you, as RAVICTI may pass into breast milk and the risk to newborns/children cannot be excluded.

Driving and using machines

Ravicti's influence on the ability to drive and use machines is important. When you take RAVICTI, you may feel dizzy or have a headache. Do not drive or use machines while you are experiencing these side effects.

3. How to take RAVICTI

Follow the instructions for administering this medicine exactly as indicated by your doctor. If you are unsure, consult your doctor or pharmacist again.

You must follow a special low-protein diet during treatment with RAVICTI.

• This diet will be designed for you by your doctor and dietitian.
• You must follow it carefully.
• You may need to take amino acid supplements.
• You will need to receive treatment and follow a diet for the rest of your life, unless you have a successful liver transplant.

Amount to be taken

Your doctor will tell you how much Ravicti to take each day.

• Your daily dose will depend on your size and weight, the amount of protein in your diet, and the overall condition of the urea cycle disorder.
• Your doctor may give you a lower dose if you have kidney or liver problems.
• You will need regular blood tests so that your doctor can determine the correct dose for you.
• Your doctor may tell you to take Ravicti more than 3 times a day. In young children, it may be 4 to 6 times a day. There should be at least 3 hours between each dose.

Taking this medicine

Your doctor will tell you how to take Ravicti oral liquid. It can be taken in the following ways:

• by mouth
• through a tube that goes from the abdomen to the stomach, called a "gastrostomy tube"
• through a tube that goes from the nose to the stomach, called a "nasogastric tube".

Take RAVICTI by mouth unless your doctor tells you otherwise.

Ravicti and meals

Take Ravicti during or just after a meal. Young children should receive the medicine during or just after feeding.

Dose measurement

• Use an oral syringe to measure your dose.

• You must have the RAVICTI bottle with an oral syringe to administer the correct amount of RAVICTI.

1. Open the RAVICTI bottle by pressing the cap and turning it to the left.
2. 
3. Place the end of the oral syringe into the syringe insert integrated into the bottle.

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

1. Fill the oral syringe by pulling the plunger back until the syringe is filled with the amount of RAVICTI liquid that your doctor has told you to take.
   1. Note: If possible, use the oral syringe size in milliliters that is closest to the recommended dose, without being less than this dose (for example, if the dose is 0.8 ml, use a 1 ml oral syringe).

1. Tap the oral syringe to remove 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 heavier 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 foods, such as ketchup, medical formulas, apple sauce, or pumpkin 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 no medicine is left in the mouth, or flush the nasogastric or gastrostomy tube with 10 ml of water using a new oral syringe. The syringe used to flush the nasogastric or gastrostomy tube must not be used to measure the dose of RAVICTI, to avoid contact between water and the medicine.

1. Close the bottle by screwing the cap.

1. Important note:Do not rinse the oral syringe between daily doses, as adding water causes RAVICTI to degrade. 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 dose of RAVICTI on another day.
3. Unused syringes should be kept to use with another bottle. Each bottle must be discarded after 14 days.

If you take more RAVICTI than you should

If you take more of this medicine than you should, talk to your doctor.

If you notice any of the following symptoms, talk to a doctor or go to a hospital immediately, as they may be signs of overdose or high ammonia:

• headache
• changes in taste
• hearing problems
• feeling disoriented
• reduced ability to remember things
• existing neurological disorders may worsen.

If you forget to take RAVICTI

If you forget a dose, take it as soon as you remember. However, in adults, if the next dose is due in less than 2 hours, skip the missed dose and take the next dose at the usual time.

For children: if the next dose is due in less than 30 minutes, skip the missed dose and give the next dose at the usual time.

• Do not take a double dose to make up for missed doses.

If you have any other questions about the use of this medicine, ask your doctor or pharmacist.
