1. What Priadel is and what it is used for
Priadel contains a medicine called lithium. 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.
Priadel can be used to manage or control:
■ Mania (feeling highly excited, being over-active and easily irritated or distracted)
■ Hypo-mania (similar to mania, but less severe)
■ Repeated periods of depression, where treatment with other medicines has not worked
■ Aggressive or self-harming behaviour
It is also used to help prevent bipolar depression - where the mood changes between feeling very high (mania) and very low (depression).
2. Before you take Priadel
Do not take Priadel if:
■ You are allergic (hypersensitive) to lithium carbonate or any of the other ingredients of Priadel (see Section 6: Further information)
Signs of an allergic reaction include: a rash, swallowing or breathing problems, swelling of your lips, face, throat or tongue
■ You are breast-feeding
■ You have heart disease
■ You have severe kidney problems
■ You have an under-active thyroid gland that is not being
treated
■ You have low levels of sodium in your body. This can happen if you are dehydrated or on a low sodium diet
■ You have an illness called 'Addison's disease'. This happens when your body does not produce enough hormones. This makes you feel tired, weak, light-headed and makes areas of your skin go darker
■ You have a rare condition called Brugada syndrome, or if anyone in your family has had Brugada syndrome. This is an abnormal condition of the heart that can make it stop beating.

Taking other medicines
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.

If your doctor decides that you should have Priadel while you are pregnant, he or she will:
■ Keep a close eye on the level of lithium in your blood. This is because your kidneys work differently while you are pregnant.

If it is decided you should have Priadel during late pregnancy or during labour, your baby may appear 'floppy'. This returns to normal without any treatment.
Breast-feeding
■ Do not breast-feed if you are taking Priadel. This is because small amounts may pass into the mother's milk
