Patient leaflet - Deferasirox DR. Reddys 180 mg film-coated tablets

1. What Deferasirox is and what it is used for

What Deferasirox is

Deferasirox Film-Coated Tablets contain an active substance called deferasirox. It is an iron chelator which is a medicine used to remove the excess iron from the body (also called iron overload). It traps and removes excess iron which is then excreted mainly in the stools.

What Deferasirox is used for

Repeated blood transfusions may be necessary in patients with various types of anaemia (for example thalassaemia, sickle cell disease or myelodysplastic syndromes (MDS)). However, repeated blood transfusions can cause a build-up of excess iron. This is because blood contains iron and your body does not have a natural way to remove the excess iron you get with your blood transfusions. In patients with non-transfusion-dependent thalassaemia syndromes, iron overload may also develop over time, mainly due to increased absorption of dietary iron in response to low blood cell counts. Over time, the excess iron can damage important organs such as the liver and heart. Medicines called iron chelators are used to remove the excess iron and reduce the risk of it causing organ damage.

Deferasirox is used to treat chronic iron overload caused by frequent blood transfusions in patients with beta thalassaemia major aged 6 years and older.

Deferasirox is also used to treat chronic iron overload when deferoxamine therapy is contraindicated or inadequate in patients with beta thalassaemia major with iron overload caused by infrequent blood transfusions, in patients with other types of anaemias, and in children aged 2 to 5 years.

Deferasirox is also used when deferoxamine therapy is contraindicated or inadequate to treat patients aged 10 years or older who have iron overload associated with their thalassaemia syndromes, but who are not transfusion dependent .

2. What you need to know before you take Deferasirox

Do not take Deferasirox

if you are allergic to deferasirox or any of the other
ingredients of this medicine (listed in section 6). If this applies to you, tell your doctor before taking Deferasirox. If you think you may be allergic, ask your doctor for advice
if you have moderate or severe kidney disease
if you are currently taking any other iron chelator
medicines.

Deferasirox is not recommended

if you are at an advanced stage of myelodysplastic
syndrome (MDS; decreased production of blood cells by the bone marrow) or have advanced cancer.

Warnings and precautions

Talk to your doctor or pharmacist before taking Deferasirox:

if you have a kidney or liver problem
if you have a cardiac problem due to iron overload
if you notice a marked decrease in your urine
output (sign of kidney problem)
if you develop a severe rash, or difficulty breathing
and dizziness or swelling mainly of the face and throat (signs of severe allergic reaction, see also section 4 “Possible side effects”)
if you experience a combination of any of the
following symptoms: rash, red skin, blistering of the lips, eyes or mouth, skin peeling, high fever, flu-like symptoms, enlarged lymph nodes (signs of severe skin reaction, see also section 4 “Possible side effects”)
if you experience a combination of drowsiness,
upper right abdominal pain, yellowing or increased yellowing of your skin or eyes and dark urine (signs of liver problems)
if you experience difficulty thinking, remembering
information, or solving problems, being less alert or aware or feeling very sleepy with low energy (signs of a high level of ammonia in your blood, which may be associated with liver or renal problems, see also section 4 “Possible side effects”)
if you vomit blood and/or have black stools
if you experience frequent abdominal pain,
particularly after eating or taking Deferasirox
if you experience frequent heartburn
if you have a low level of platelets or white blood
cells in your blood test
if you have blurred vision
if you have diarrhoea or vomiting.

If any of these apply to you, tell your doctor straight away.

Monitoring your Deferasirox treatment

You will have regular blood and urine tests during treatment. These will monitor the amount of iron in your body (blood level of ferritin) to see how well Deferasirox is working. The tests will also monitor your kidney function (blood level of creatinine, presence of protein in the urine) and liver function (blood level of transaminases). Your doctor may require you to undergo a kidney biopsy, if he/she suspects significant kidney damage. You may also have MRI (magnetic resonance imaging) tests to determine the amount of iron in your liver. Your doctor will take these tests into consideration when deciding on the dose of Deferasirox most suitable for you and will also use these tests to decide when you should stop taking Deferasirox.

Your eyesight and hearing will be tested each year during treatment as a precautionary measure.

Older people (age 65 years and over)

Deferasirox can be used by people aged 65 years and over at the same dose as for other adults. Elderly patients may experience more side effects (in particular diarrhoea) than younger patients. They should be monitored closely by their doctor for side effects that may require a dose adjustment.

Children and adolescents

Deferasirox can be used in children and adolescents receiving regular blood transfusions aged 2 years and over and in children and adolescents not receiving regular blood transfusions aged 10 years and over. As the patient grows the doctor will adjust the dose.

Deferasirox is not recommended for children aged under 2 years.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant or are planning to have a baby, ask your doctor for advice before taking this medicine.

Deferasirox is not recommended during pregnancy unless clearly necessary.

If you are currently using a hormonal contraceptive to prevent pregnancy, you should use an additional or different type of contraception (e.g. condom), as Deferasirox may reduce the effectiveness of hormonal contraceptives.

Breastfeeding is not recommended during treatment with Deferasirox.

Driving and using machines

If you feel dizzy after taking Deferasirox, do not drive or operate any tools or machines until you are feeling normal again.

3. How to take Deferasirox

Treatment with Deferasirox will be overseen by a doctor who is experienced in the treatment of iron overload caused by blood transfusions.

Always take this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.

How much Deferasirox to take

The dose of Deferasirox is related to body weight for all patients. Your doctor will calculate the dose you need and tell you how many tablets to take each day.

The usual daily dose for Deferasirox at the start of the
treatment for patients receiving regular blood transfusions is 14 mg per kilogram body weight. A higher or lower starting dose may be recommended by your doctor based on your individual treatment needs.
The usual daily dose for Deferasirox at the start of the
treatment for patients not receiving regular blood transfusions is 7 mg per kilogram body weight.
Depending on how you respond to treatment, your
doctor may later adjust your treatment to a higher or lower dose.
The maximum recommended daily dose for
Deferasirox is:
- 28 mg per kilogram body weight for patients
  receiving regular blood transfusions
- 14 mg per kilogram body weight for adult
  patients not receiving regular blood transfusions
- 7 mg per kilogram body weight for children and
  adolescents not receiving regular blood transfusions.

Deferasirox can also be available as “dispersible” tablets. If you are switching from the dispersible tablets to these film-coated tablets, your dose will change. Your doctor will calculate the dose you need and tell you how many film-coated tablets to take each day.

When to take Deferasirox

Take Deferasirox once a day, every day, at about the
same time each day with some water.
Take Deferasirox either on an empty stomach or with
a light meal.

Taking Deferasirox at the same time each day will also help you remember when to take your tablets.

For patients who are unable to swallow whole tablets, Deferasirox may be crushed and taken by sprinkling the full dose onto soft food such as yogurt or apple sauce (pureed apple). The food should be immediately and completely consumed. Do not store it for future use.

How long to take Deferasirox

Continue taking Deferasirox every day for as long as your doctor tells you. This is a long-term treatment, possibly lasting for months or years. Your doctor will regularly monitor your condition to check that the treatment is having the desired effect (see also section 2: “Monitoring your Deferasirox treatment”).

If you have questions about how long to take Deferasirox, talk to your doctor.

If you take more Deferasirox than you should

If you have taken too much Deferasirox, or if someone else accidentally takes your tablets, contact your doctor or hospital for advice straight away. Show the doctor the pack of tablets. Urgent medical treatment may be necessary. You may experience effects such as abdominal pain, diarrhoea, nausea and vomiting and kidney or liver problems that can be serious.

If you forget to take Deferasirox

If you miss a dose, take it as soon as you remember on that day. Take your next dose as scheduled. Do not take a double dose on the next day to make up for the forgotten tablet(s).

If you stop taking Deferasirox

Do not stop taking Deferasirox unless your doctor tells you to. If you stop taking it, the excess iron will no longer be removed from your body (see also above section “How long to take Deferasirox”).
