1. What is Cystagon and what is it used for
Cystinosis is a metabolic disease known as 'nephropathic cystinosis' characterized by the 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 causes damage to the kidneys and the elimination of excessive amounts of sugar (glucose), proteins, and electrolytes. At different ages, different organs may be affected.
CYSTAGON is prescribed to treat this rare hereditary disorder. CYSTAGON is a medicine that reacts with cystine, reducing its levels in cells.
2. What you need to know before you take Cystagon
Do not take CYSTAGON:
- if you or your child are allergic to cysteamine bitartrate or penicillamine or any of the other ingredients of this medicine (listed in section 6).
- if you are pregnant, this is especially important during the first trimester
- if you are breast-feeding.
Warnings and precautions:
- When your disease or your child's disease has been confirmed by measurements of white blood cell cystine, treatment with CYSTAGON should be started as soon as possible.
- Some cases of skin lesions in the form of small hard bumps, mainly on the elbows, have been reported in children treated with high doses of different cysteamine preparations. These lesions were associated with stretch marks on the skin and bone lesions, such as fractures and bone deformities, and with loose joints.
Your doctor may periodically ask you for physical examinations of the skin and X-rays of the bones to monitor the effects of the medicine. Self-examination of the skin by the patient or parents is recommended. If any skin or bone abnormality appears, you should inform your doctor immediately.
- Your doctor may periodically ask you for blood tests to monitor your blood cell count.
- CYSTAGON does not prevent the accumulation of cystine crystals in the eyes. If cysteamine eye drops have been used for this purpose, you should continue using them...
- Unlike phosphocysteamine, another active substance similar to cysteamine bitartrate, CYSTAGON does not contain phosphate. You may be taking phosphate supplements, and it is possible that your doctor may modify the dose of these supplements when switching your treatment from CYSTAGON to phosphocysteamine.
- The capsules should not be given to children under the age of approximately 6 years to avoid the risk of aspiration into the lungs.
- Do not ingest the desiccant container in the bottle.
Other medicines and CYSTAGON

3. How to take Cystagon
Follow your doctor's instructions for taking this medicine exactly. If you are in doubt, consult your doctor again.
The dose of CYSTAGON prescribed for you or your child will depend on their weight and age.
For children up to 12 years of age, the dose will be based on body size (surface area), with the usual dose being 1.30 g/m2 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/m2/day.
CYSTAGON should always be taken orally and exactly as instructed by your doctor or your child's doctor. To ensure CYSTAGON works properly, it is necessary:
- To follow the doctor's instructions exactly. Do not increase or decrease the amount of medicine without the doctor's approval.
- Not to give the hard capsules to children under the age of 6 because they may not swallow them and may choke. For children under 6 years of age, the hard capsule can be opened and its contents sprinkled on food (such as milk, potatoes, or starchy foods like flour), or mixed with the baby bottle. Do not mix with acidic drinks, such as orange juice. For complete instructions, consult your doctor.
- The medical treatment prescribed for you or your child will include, in addition to CYSTAGON, one or more supplements to replace important electrolytes eliminated by the kidneys. It is essential to take or give these supplements exactly as instructed. If you forget several doses of one of the supplements, or if you notice weakness or drowsiness, you should consult your doctor immediately.
- To determine the correct dose of CYSTAGON, it is necessary to have periodic blood tests to measure the amount of cystine inside white blood cells. Your doctor or your child's doctor will determine when to perform the blood tests. It is also necessary to perform periodic blood and urine tests to measure the concentrations of important electrolytes in the body, so your doctor can adjust the doses of electrolyte supplements as needed.
CYSTAGON should be taken 4 times a day, every 6 hours, preferably with meals or immediately after meals. It is essential to respect the rule of taking the dose every six hours as strictly as possible.
Treatment with CYSTAGON should be continued indefinitely as indicated by your doctor.
