Contents of the pack and other information
PHEBURANE contains the active substance sodium phenylbutyrate which is used to treat patients of all ages with urea cycle disorders. These rare disorders are due to a deficiency of certain liver enzymes which are necessary to eliminate waste nitrogen in the form of ammonia.
Nitrogen is a building block of proteins, which are an essential part of the food we eat. As the body breaks down protein after eating, waste nitrogen, in the form of ammonia, accumulates because the body cannot eliminate it. Ammonia is especially toxic for the brain and leads, in severe cases, to reduced levels of consciousness and to coma.
PHEBURANE helps the body to eliminate waste nitrogen, reducing the amount of ammonia in your body. However PHEBURANE must be used along with a diet reduced in proteins, designed especially for you by the doctor and the dietician. You must follow this diet carefully.
are allergic to sodium phenylbutyrate or any of the other ingredients of this medicine (listed in section 6).
are pregnant.
are breast-feeding.
Talk to your doctor or pharmacist before taking PHEBURANE if you:
suffer from congestive heart failure (a type of heart disease where the heart cannot pump enough blood around the body) or a decrease in your kidney function.
have decreased kidney or liver function, since PHEBURANE is eliminated from the body through the kidney and liver.
PHEBURANE will not prevent the occurrence of an acute excess of ammonia in the blood, a condition which usually constitutes a medical emergency. If this happens you will develop symptoms such as feeling sick (nausea), being sick (vomiting), confusion and will need to get urgent medical help.
If you need laboratory tests, it is important to remind your doctor that you are taking PHEBURANE, since sodium phenylbutyrate may interfere with certain laboratory test results (such as blood electrolytes or protein, or liver function tests)
In case of any doubt, ask your doctor or pharmacist.
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.
It is especially important to tell your doctor if you are taking medicines containing:
valproate (an antiepileptic medicine),
haloperidol (used in certain psychotic disorders),
corticosteroids (medicines that are used to provide relief for inflamed areas of the body),
probenecid (for treatment of hyperuricaemia, high levels of uric acid in the blood, associated with gout)
These medicines may change the effect of PHEBURANE and you will need more frequent blood tests. If you are uncertain if your medicines contain these substances, you should check with your doctor or pharmacist.
Do not use PHEBURANE if you are pregnant, because this medicine can harm your unborn baby.
If you are a woman who could get pregnant, you must use reliable contraception, during treatment with PHEBURANE. Talk to your doctor for the details.
Do not use PHEBURANE if you are breast-feeding, because this medicine can pass into the breast milk and may harm your baby.
PHEBURANE is unlikely to affect your ability to drive and use machines.
This medicine contains 124 mg (5.4 mmol) of sodium per 1 g of sodium phenylbutyrate. Talk to your doctor or pharmacist if you need 3 or more grams daily for a prolonged period, especially if you have been advised to follow a low salt (sodium) diet.
This medicine contains 768 mg of sucrose per 1 g of sodium phenylbutyrate. This should be taken into account if you have diabetes mellitus. If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicine.
Always take this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.
The daily dose of PHEBURANE will be based on your body weight or body surface and adjusted according to your protein tolerance and diet. You will need regular blood tests to determine the correct daily dose. Your doctor will tell you the amount of granules you should take.
You should take PHEBURANE by mouth. Because it dissolves slowly, PHEBURANE should not be administered through a gastrostomy (tube that goes through the abdomen to the stomach) or through a nasogastric tube (tube that goes through the nose to the stomach).
PHEBURANE must be taken with a special diet reduced in protein.
You should take PHEBURANE with each meal or feeding. In small children this can be 4 to 6 times per day.
The doses of PHEBURANE prescribed by your doctor are expressed in grams of sodium phenylbutyrate. A calibrated measuring spoon which dispenses up to 3 g of sodium phenylbutyrate at a time is provided with this medicine. Only use this measuring spoon to measure out the dose of PHEBURANE. The measuring spoon must not be used for any other medicine.
To measure the dose:
Lines on the spoon indicate the amount of PHEBURANE in gram of sodium phenylbutyrate.
Take the correct amount as prescribed by your doctor.
Pour granules directly into the spoon as shown by the picture (on the outer carton and in this leaflet)
Tap the spoon once on a table to give a horizontal level of granules and continue filling if necessary
The granules can be directly swallowed with a drink (water, fruit juices, protein-free infant formulas) or sprinkled on to a spoonful of solid foods (mashed potatoes or apple sauce). If you mix them with food, it is important that you take it immediately. This will keep the granules from producing any taste.
You will need to take this medicine and to follow a diet throughout your life.
Patients who have taken very high doses of sodium phenylbutyrate experienced:
sleepiness, tiredness, light-headedness and less frequently confusion,
headache,
changes in taste (taste disturbances),
decrease in hearing,
disorientation,
impaired memory,
worsening of existing neurological conditions.
If you experience any of these symptoms, you should immediately contact your doctor or the nearest hospital emergency department for supportive treatment.
You should take a dose as soon as possible with your next meal. Make sure that there are at least 3 hours between two doses. Do not take a double dose to make up for a forgotten dose.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
