Thalidomide capsules are used with two other medicines called ‘melphalan’ and ‘prednisone’ to treat adults with a type of cancer called multiple myeloma. It is used in people who have recently been diagnosed and who have not been prescribed another medicine for their multiple myeloma before who are aged 65 years and over, or aged less than 65 years who cannot be treated with high dose chemotherapy, which can be very difficult for the body to handle.

Multiple myeloma is a type of cancer which affects a certain type of white blood cell, called the plasma cell. These cells collect in the bone marrow and divide out of control. This can damage the bone and kidneys. Multiple myeloma generally cannot be cured. However, the signs and symptoms can be greatly reduced or disappear for a period of time. This is called a ‘remission’.

Thalidomide capsules work by helping the body’s immune system and directly attacking the cancer. It works in a number of different ways by:

• stopping the cancer cells developing.
• stopping blood vessels growing in the cancer.
• stimulating part of the immune system to attack the cancer cells.

• if you are allergic to thalidomide or any of the other ingredients of this medicine (listed in section 6).
• if you are pregnant or think you may be pregnant or are planning to become pregnant, as Thalidomide capsules causes birth defects and foetal death.
• if you are able to become pregnant, unless you are able to follow or comply with the required contraceptive measures to prevent you from becoming pregnant (see section 2 “Warnings and precautions” and “Pregnancy and breast-feeding”).
• if you are able to become pregnant, your doctor will record with each prescription that the necessary measures have been taken and will provide you with this confirmation.

Do not take Thalidomide capsules if any of the above applies to you. If you are not sure, talk to your doctor or pharmacist before taking Thalidomide capsules.

Talk to your doctor, pharmacist or nurse before taking Thalidomide capsules.

For women taking Thalidomide capsules

Before starting the treatment, you should ask your doctor if you are able to become pregnant, even if you think this is unlikely. Even if you do not have a menstrual bleeding following cancer therapy, you may become pregnant.

If you are able to become pregnant:

• Your doctor will make sure that you have pregnancy tests
  • before treatment
  • every 4 weeks during treatment
  • 4 weeks after stopping treatment.
• You must use one effective method of contraception:
  • for at least 4 weeks before starting treatment
  • during treatment
  • until at least 4 weeks after stopping treatment.

Your doctor will tell you what method of contraception to use.

If you are able to become pregnant, your doctor will record with each prescription that the necessary measures, as outlined above, have been taken.

For men taking Thalidomide capsules

Thalidomide passes into semen. Therefore, do not have unprotected intercourse, even if you had a vasectomy.

• Pregnancy and any exposure during pregnancy must be avoided. Always use a condom:
  • during treatment
  • for at least 7 days after stopping treatment.
• You must not donate semen:
  • during treatment
  • for at least 7 days after stopping treatment.

For all patients

Talk to your doctor before taking Thalidomide capsules if:

• you do not understand the contraception advice given to you by your doctor or if you do not feel able to follow this advice.
• you have had a heart attack, have ever had a blood clot in the past, or if you smoke, have high blood pressure or high cholesterol levels. During the treatment with Thalidomide capsules you have an increased risk of developing blood clots in the veins and arteries (see also section 4 “Possible side effects”).
• you have experienced or have existing neuropathy i.e. nerve damage causing tingling, abnormal co-ordination or pain in your hands or feet (see also section 4 “Possible side effects”).
• you experienced or have existing slow heart rate (this may be a symptom of bradycardia).
• you have high blood pressure in the arteries of the lungs (see also section 4 “Possible side effects”).
• you have a fall in the number of white blood cells (neutropenia) accompanied by fever and infection.
• you have a fall in the number of platelets. You will be more prone to bleeding and bruising.
• you have or have had injury to the liver (hepatic disorders) including abnormal liver test results.
• you experience or have experienced in the past severe skin reactions called Stevens-Johnson syndrome, toxic epidermal necrolysis or drug reaction with eosinophilia and systemic symptoms (which is also known as DRESS or drug hypersensitivity syndrome). (For description of symptoms see section 4 “Possible side effects”).
• you have had an allergic reaction whilst taking Thalidomide capsules such as rash, itching, swelling, dizziness or trouble breathing.
• you have experienced sleepiness.
• you have experienced fever, chills and severe shaking, and possibly complicated by low blood pressure and confusion (these may be symptoms of severe infections).
• you have or have ever had previous viral infection, particularly varicella zoster, hepatitis B infection, or HIV. If you are in doubt, talk to your doctor. Treatment with Thalidomide capsules may cause a virus to become active again in patients who carry it, resulting in a recurrence of the infection. Your doctor should check whether you have ever had hepatitis B infection.
• you have kidney or liver problems (see also section 4 “Possible side effects”).

Your thyroid function may be checked before you take thalidomide and monitored during treatment.

At any time during or after your treatment, tell your doctor or nurse immediately if you experience: blurred, loss of or double vision, difficulty speaking, weakness in an arm or a leg, a change in the way you walk or problems with your balance, persistent numbness, decreased sensation or loss of sensation, memory loss or confusion. These may all be symptoms of a serious and potentially fatal brain condition known as progressive multifocal leukoencephalopathy (PML). If you had these symptoms prior to treatment with Thalidomide capsules, tell your doctor about any change in these symptoms.

Your doctor may check if you have a high total amount of tumour throughout the body, including your bone marrow. This could lead to a condition where the tumours break down and cause unusual levels of chemicals in the body which can lead to kidneys failure (this condition is called Tumour Lysis Syndrome) (see also section 4 “Possible side effects”).

Your doctor should evaluate if you develop additional types of haematological malignancies (called acute myeloid leukaemia and myelodysplastic syndromes) during your treatment with Thalidomide capsules (see also section 4 “Possible side effects”).

You must not donate blood during Thalidomide capsules treatment and for at least 7 days after stopping treatment.

If you are not sure if any of the above apply to you, talk to your doctor before taking Thalidomide capsules.

• slow the heart rate (induce bradycardia, such as anticholinesterases and beta blockers).
• are used for heart problems and complications (such as digoxin), or for thinning the blood (such as warfarin).
• are associated with neuropathy such as other treatments for cancer.
• are used for contraception.

Pregnancy

Thalidomide causes severe birth defects or death to an unborn baby.

• As little as one capsule taken by a pregnant woman can cause a baby to have serious birth defects.
• These defects can include shortened arms or legs, malformed hands or feet, eye or ear defects, and problems with internal organs.

If you are pregnant, you must not take Thalidomide capsules. In addition, you must not become pregnant while taking Thalidomide capsules.

• Extremely intense and serious skin reactions. The adverse reaction of the skin may appear as rashes with or without blisters. Skin irritation, sores or swelling in the mouth, throat, eyes, nose and around the genitals, oedema and fever and flulike symptoms may occur. These symptoms may be signs of the rare and serious skin reactions Stevens-Johnson syndrome, toxic epidermal necrolysis or DRESS syndrome.
• Allergic reactions such as a localised or generalised pruritic rash, angioedema and anaphylactic reaction (serious types of allergic reaction that may be manifested as hives, rashes, swelling of eyes, mouth or face, difficulty of breathing, or itching).

• Numbness, tingling, abnormal coordination or pain in your hands and feet.
  This may be due to nerve damage (called ‘peripheral neuropathy’), which is a very common side effect. It may become very severe, painful and disabling. If you experience such symptoms, speak to your doctor straight away, who may reduce the dose or discontinue the treatment. This side effect usually happens after you have been taking this medicine for several months but can happen sooner than this. It can also happen sometime after treatment has stopped. It may not go away, or may go away slowly.
• Sudden pain in your chest or difficulty in breathing.
  This may be due to blood clots in the arteries leading to your lungs (called ‘pulmonary embolism’), which is a common side effect. These can happen during treatment, or after treatment has stopped.
• Pain or swelling in your legs, especially in your lower leg or calves.
  This may be due to blood clots in the veins of your leg (deep vein thrombosis), which is a common side effect. These can happen during treatment, or after treatment has stopped.
• Chest pain spreading to the arms, neck, jaw, back or stomach, feeling sweaty and breathless, feeling sick or vomiting.
  These may be symptoms of a heart attack/myocardial infarction (which may be due to blood clots in the arteries of your heart).
• Having difficulty in seeing or speaking, which is temporary.
  These may be symptoms of a stroke (which may be due to a clot in an artery in your brain).
• Fever, chills, sore throat, cough, mouth ulcers or any other symptoms of infection.
• Bleeding or bruising in the absence of injury.

It is important to note that a small number of patients with multiple myeloma may develop additional types of cancer, especially haematological malignancies, and it is possible that this risk may be increased with Thalidomide capsules treatment; therefore your doctor should carefully evaluate the benefit and risk when you are prescribed Thalidomide capsules.
