1. What is CYSTAGON and what is it used for

Cystinosis is a metabolic disease called “nephropathic cystinosis”, characterized by an abnormal accumulation
of the amino acid cystine in various organs of the body, such as the kidneys, eyes, muscles, pancreas and
brain. The accumulation of cystine damages the kidneys and causes the excretion of excessive amounts of
glucose, proteins and electrolytes. Different organs are affected at different ages.
CYSTAGON is prescribed for the treatment of this rare hereditary disorder. CYSTAGON is a
medicine that reacts with cystine to reduce its level inside the cells.

2. What you need to know before using CYSTAGON

Do not use CYSTAGON

• if you - or the child - are allergic to cysteamine bitartrate or penicillamine or to any of the other ingredients of this medicine (listed in section 6).
• if you are pregnant, especially during the first trimester.
• if you are breastfeeding.

Warnings and precautions

• If the disease has been confirmed in you or the child, by measuring cystine levels in white blood cells, therapy with CYSTAGON should be started as soon as possible.
• Some cases of skin lesions on the elbow, in the form of small hard masses, have been reported in children treated with high doses of various cysteamine-based preparations. These lesions were associated with skin striae and bone lesions, such as fractures or bone deformities, and joint laxity. The doctor may require periodic medical visits and X-rays for the skin and bones, in order to monitor the effects of the medicine. Self-examination of the skin is also recommended, for both you and the child. If skin or bone abnormalities appear, inform your doctor immediately.
• The doctor may require periodic monitoring of blood cell counts.
• It has not been demonstrated that CYSTAGON prevents the accumulation of cystine crystals in the eye. If a cysteamine ophthalmic solution has been used for this purpose, continue its use.
• Unlike phosphocysteamine, another active ingredient similar to cysteamine bitartrate, CYSTAGON does not contain phosphate. You may already be taking phosphate supplements and their dose may require changes when CYSTAGON replaces phosphocysteamine.
• To avoid the risk of aspiration into the lungs, capsules should not be given to children under approximately 6 years of age.
• Do not ingest the desiccant container placed inside the bottle.

Pregnancy
Do not use CYSTAGON if you are pregnant. Consult your doctor if you are planning to become
pregnant.

Breastfeeding

fully known.

3. How to use CYSTAGON

Use this medicine following the instructions of your doctor or pediatrician exactly. If you have
any doubts, consult your doctor.
The dose of CYSTAGON prescribed for you or your child will depend on their age and weight or
on those of your child.
For children up to 12 years of age, the dose will be based on body surface area; the usual dose is
1.30 g/m of body surface area per day.
For patients over 12 years of age and weighing more than 50 kg, the usual dose is 2 g/day.
In any case, the usual dose should not exceed 1.95 g/m /day.
CYSTAGON must be taken or administered only orally and exactly as directed
by your doctor or pediatrician. For CYSTAGON to work correctly, follow these instructions:

• Strictly adhere to the doctor's instructions. Do not increase or decrease the amount of medicine without the doctor's approval.
• Hard capsules should not be given to children under approximately six years of age as they may not be able to swallow them and therefore choke. For children under approximately six years of age, the hard capsule can be opened and its contents poured onto food (e.g. milk, potatoes or starch-based foods) or mixed into formula. Do not add it to acidic beverages such as orange juice. Consult your doctor for specific instructions.
• Your or your child's treatment may include, in addition to CYSTAGON, one or more supplements to replace important electrolytes that are lost through the kidneys. It is important to administer or take these supplements exactly as directed. Consult your doctor if you have missed several doses of these supplements or if you experience weakness or drowsiness.
• Regular blood tests to measure the amount of cystine within leukocytes help determine the correct dosage of CYSTAGON. Your doctor or pediatrician will arrange the necessary

blood tests. Also, regular blood and urine tests to measure the levels of
electrolytes important for the body help the doctor to correctly establish the doses of
the supplements.
CYSTAGON must be taken 4 times a day, every 6 hours, preferably immediately after meals
or during meals. It is important to take the dose respecting the 6-hour intervals as much as possible.
Treatment with CYSTAGON is of indefinite duration, as established by the doctor.
