1. What is AMMONAPS and what is it used for

AMMONAPS is prescribed to patients with urea cycle disorders. Patients with these rare disorders lack certain liver enzymes. Since nitrogen is a constituent of proteins, it accumulates in the body after protein consumption. Excess nitrogen, in the form of ammonia, is particularly toxic to the brain and, in severe cases, can cause a reduction in the level of consciousness and coma.

AMMONAPS helps the body eliminate excess nitrogen and reduces the amount of ammonia in the body.

Doctor consultation

Discuss your symptoms and treatment with a doctor online.

2. What you need to know before you take AMMONAPS

Do not take AMMONAPS:

  • If you are pregnant.
  • If you are breast-feeding.
  • If you are allergic (hypersensitive) to sodium phenylbutyrate or any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions

Consult your doctor or pharmacist before taking AMMONAPS

  • If you have heart failure, reduced kidney function or other conditions where the sodium content of this medicine may worsen your condition.
  • If you have reduced liver or kidney function, as AMMONAPS is eliminated from the body through the kidneys and liver.

AMMONAPS should be combined with a low-protein diet that your doctor or dietitian has specifically designed for you. You should follow this diet carefully.

AMMONAPS does not completely prevent excess ammonia in the blood and is not suitable for treating this condition, which is a medical emergency.

If you are to have tests, it is important that you remind your doctor that you are taking AMMONAPS, as sodium phenylbutyrate may alter the results of some tests.

Taking AMMONAPS with other medicines

Tell your doctor or pharmacist if you are using, have recently used or might use any other medicines.

It is especially important that you tell your doctor if you are taking medicines that contain:

  • valproic acid (an antiepileptic medicine)
  • haloperidol (used to treat some psychotic disorders)
  • corticosteroids (medicines similar to cortisone used to relieve inflamed areas of the body)
  • probenecid (for the treatment of hyperuricemia associated with gout)

These medicines may change the effect of AMMONAPS, and you may need to have blood tests more frequently. If you are not sure if your medicines contain these substances, consult your doctor or pharmacist.

Pregnancy and breast-feeding

Do not take AMMONAPS if you are pregnant, as this medicine may harm the fetus. If you could become pregnant, you must use an effective contraceptive method during treatment with AMMONAPS.

Do not use AMMONAPS if you are breast-feeding, as this medicine may pass into breast milk and harm your baby.

Driving and using machines

No studies on the ability to drive and use machines have been performed.

AMMONAPS contains sodium

A small white spoonful of AMMONAPS granules contains 149 mg of sodium.

A medium yellow spoonful of AMMONAPS granules contains 408 mg of sodium.

A large blue spoonful of AMMONAPS granules contains 1,200 mg of sodium.

Consult your doctor or pharmacist if you need 2 or more small white spoonfuls or 1 or more medium yellow spoonfuls or large blue spoonfuls daily for a prolonged period, especially if you have been advised to follow a low-salt (sodium) diet.

3. How to take AMMONAPS

Follow the instructions for administration of this medicine exactly as prescribed by your doctor.

In case of doubt, consult your doctor or pharmacist again.

Dosage

The daily dose of AMMONAPS will be calculated according to your tolerance to proteins, diet, and body weight or body surface area. You will need to have regular blood tests to adjust the correct daily dose. Your doctor will tell you how many tablets to take.

Method of administration

AMMONAPS should be taken in equal doses by mouth, through gastrostomy (a tube that goes from the abdomen to the stomach) or through a nasogastric tube (a tube that goes from the nose to the stomach).

AMMONAPS should be taken while following a special low-protein diet.

AMMONAPS should be taken with each meal or feeding. In small children, this may be 4 to 6 times a day.

To measure the dose:

  • Shake the bottle slightly before opening it.
  • Use the correct spoon depending on the amount of AMMONAPS you need: 1.2 g = small white spoon, 3.3 g = medium yellow spoon, and 9.7 g = large blue spoon.
  • Take a heaped spoonful of granules from the bottle.
  • Pass a flat surface, e.g. the back of a knife blade, over the spoon to remove excess granules.
  • The granules remaining in the spoon correspond to the measure of one spoonful.
  • Remove the correct number of spoonfuls of granules from the bottle.

If administration is by mouth:

Mix the measured dose with solid foods (such as mashed potato or apple sauce) or with liquids (such as water, apple juice, orange juice, or protein-free infant formula) and swallow immediately after mixing.

Patients with gastrostomy or nasogastric tube:

Mix the granules with water until no dry granules remain (stirring the solution helps to dissolve the granules). When the granules are dissolved in water, you will get a white, milky liquid. Take the solution immediately after mixing.

You will need to follow the diet and treatment for life unless you have a successful liver transplant.

If you take more AMMONAPS than you should

Patients who have taken very high doses of AMMONAPS have experienced:

  • drowsiness, fatigue, dizziness, and, less frequently, confusion.
  • headache.
  • changes in taste (taste disorders).
  • reduced hearing.
  • disorientation.
  • memory problems.
  • worsening of existing neurological conditions.

If you experience any of these symptoms, you should contact your doctor or the emergency department of the nearest hospital immediately for symptomatic treatment.

If you forget to take AMMONAPS

You should take a dose as soon as possible with the next meal. Make sure that at least 3 hours pass between two doses. Do not take a double dose to make up for forgotten doses.

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