1. what syonell is and what it is used for

The name of your medicine is Syonell 250mg Gastro-Resistant tablets or 500mg Gastro-Resistant tablets. Syonell tablets contains a medicine called valproate semisodium. This belongs to a group of medicines called mood stabilisers. It works by stabilising the levels of chemicals in your brain that affect your mood.

Syonell can be used to manage or control mania (feeling highly excited, enthusiastic, being over-active and easily irritated or distracted) caused by bipolar disorder. Bipolar disorder is where the mood changes between feeling very high (mania) and very low (depression).

Syonell can be used when lithium cannot be used.

2. what you need to know before you take syonell

Do not take Syonell if:

• You are allergic (hypersensitive) to valproate semisodium or any of the other ingredients of this medicine (listed in section 6)

Signs of an allergic reaction include: a rash, swallowing or breathing problems, swelling of your lips, face, throat or tongue

• You have liver problems or you or your family have a history of liver problems, especially if caused by taking a medicine
• You have a rare illness called porphyria which affects your metabolism
• You have a known metabolic disorder, i.e. a urea cycle disorder
• You have a genetic problem caused by a mitochondrial disorder (e.g. Alpers-Huttenlocher syndrome)
• You are pregnant (see Pregnancy, breast-feeding and fertility-important advice for women' below)

If you are a woman able to have a baby, you must not take Syonell, unless you use an effective method of birth control (contraception) at all times during your treatment with Syonell. Do not stop taking Syonell or your contraception, until you have discussed this with your doctor. Your doctor will advise you further (see below under “Pregnancy, breast-feeding and fertility – Important advice for women”).

Do not take this medicine if any of the above apply to you. If you are not sure, talk to your doctor or pharmacist before taking Syonell.

A small number of people being treated with mood stabilisers such as valproate semisodium have had thoughts of harming or killing themselves. If at any time you have these thoughts, immediately contact your doctor.

In patients with epilepsy convulsions may become worse or happen more frequently whilst taking this medicine. If this happens contact your doctor immediately.

Talkto your doctor or pharmacist before taking your medicine if:

Other medicines and Syonell

Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines. This includes medicines you buy without a prescription, including herbal medicines. This is because Syonell can affect the way some other medicines work. Also, some medicines can affect the way Syonell works.

In particular, do not take and check with your doctor if you are taking any of the following:

• Some medicines used for pain and inflammation called ‚salicylates‘ such as aspirin.

The following medicines can affect the way Syonell works or Syonell can affect the way some of these medicines work:

• Some medicines used to treat fits (epilepsy) such as phenobarbital, primidone, phenytoin, carbamazepine, rufinamide, topiramate, acetazolamide, lamotrigine and felbamate. Your doctor may change the dose of one of your medicines and monitor your treatment closely
• Medicines for depression
• Medicines used to calm emotional and mental health problems (including schizophrenia, bipolar disorder and depression) such as quetiapine, diazepam and olanzapine
• Zidovudine and protease inhibitors such as lopinavir and ritonavir – used for HIV infection
• Carbapenem agents (antibiotics used to treat bacterial infections) such as panipenem, imipenem, meropenem, rifampicin and erythromycin. The combination of Syonell and carbapenems should be avoided because it may decrease the effect of your medicine
• Some medicines used for malaria such as mefloquine or chloroquine
• Medicines used for thinning the blood such as warfarin. Your doctor may change your dose of the blood thinning medicine and monitor your treatment closely.
• Temozolomide – used for cancer
• Cimetidine – used for stomach ulcers
• Cholestyramine – used for lowering blood cholesterol levels
• Nimodipine
• Propofol – used for anaesthesia
• Oestrogen-containing products (including some birth control pills).

Pregnancy,breast-feeding and fertility

Important advice for women

• You must not use Syonell if you are pregnant.
• If you are a woman able to have a baby, you must not take Syonell, unless you use an effective method of birth control (contraception) during your entire treatment with Syonell.
• Do not stop taking Syonell or your birth control (contraception), until you have discussed this with your doctor. Your doctor will advise you further.

The risks of valproate when taken during pregnancy

• Talk to your doctor immediately if you are planning to have a baby or are pregnant.
• Valproate carries a risk if taken during pregnancy. The higher the dose, the higher the risks but all doses carry a risk.
• It can cause serious birth defects and can affect the way in which the child develops as it grows. The most frequently reported birth defects include spina bifida (where the bones of the spine are not properly developed); facial and skull malformations; heart, kidney, urinary tract and sexual organ malformations; limb defects and multiple associated malformations affecting several organs and parts of the body. Birth defects may result in disabilities which may be severe.
• Hearing problems or deafness have been reported in children exposed to valproate during pregnancy
• Eye malformations have been reported in children exposed to valproate during pregnancy in association with other congenital malformations. These eye malformations may affect vision.
• If you take valproate during pregnancy you have a higher risk than other women of having a child with birth defects that require medical treatment. Because valproate has been used for many years we know that in women who take valproate around 10 babies in every 100 will have birth defects. This compares to 2–3 babies in every 100 born to women who don't have bipolar disorder.
• It is estimated that up to 30–40% of preschool children whose mothers took valproate during pregnancy may have problems with early childhood development. Children affected can be slow to walk and talk, intellectually less able than other children, and have difficulty with language and memory.
• Autistic spectrum disorders are more often diagnosed in children exposed to valproate during pregnancy and there is some evidence that children exposed to valproate during pregnancy are at increased risk of developing Attention Deficit Hyperactivity Disorder (ADHD).
• Before prescribing this medicine to you, your doctor will have explained what might happen to your baby if you become pregnant whilst taking valproate. If you decide later you want to have a child you should not stop taking your medicine or your method of birth control (contraception) until you have discussed this with your doctor.
• If you are a parent or a caregiver of a female child treated with valproate, you

should contact their doctor once your child experiences their first period (menarche).

• Some birth control pills (oestrogen-containing birth control pills) may lower valproate levels in your blood. Make sure you talk to your doctor about the method of birth control (contraception) that is the most appropriate for you.
• Ask your doctor about taking folic acid when trying for a baby. Folic acid can lower the general risk of spina bifida and early miscarriage that exists with all pregnancies. However, it is unlikely that it will reduce the risk of birth defects associated with valproate use.

If this is the first time you have been prescribed Syonell your doctor will have explained the risks to an unborn child if you become pregnant.

If you are planning to have a baby, first schedule an appointment with your doctor.

Do not stop taking Syonell or your birth control (contraception), until you have discussed this with your doctor. Your doctor will advise you further.

Babies born to mothers who have been on valproate are at serious risk of birth defects and problems with development which can be seriously debilitating. Your doctor will refer you to a specialist experienced in the management of bipolar disorder, so that alternative treatment options can be evaluated early on. Your specialist can put several actions in place so that your pregnancy goes as smoothly as possible and any risks to you and your unborn child are reduced as much as possible.

Your specialist may decide to change the dose of Syonell, switch you to another medicine, or stop treatment with Syonell, a long time before you become pregnant – this is to make sure your illness is stable.

Ask your doctor about taking folic acid when trying for a baby. Folic acid can lower the general risk of spina bifida and early miscarriage that exists with all pregnancies. However, it is unlikely that it will reduce the risk of birth defects associated with valproate use.

Key messages:

• Do not stop taking Syonell unless your doctor tells you to.
• Do not stop using your method of birth control (contraception) before you have talked to your doctor and worked together on a plan to ensure your condition is controlled and the risks to your baby are reduced.
• First schedule an appointment with your doctor. During this visit your doctor will make sure you are well aware of and have understood all the
