1. What Mysoline is and what it is used for
Mysoline contains primidone as the active ingredient; this belongs to a group of medicines used to treat seizures.
Mysoline is used for the treatment of certain types of epilepsy, seizures (fits) or shaking attacks (essential tremor).
2. Before you use Mysoline
Do not take Mysoline if you:
• are allergic (hypersensitive) to primidone, a substance called phenobarbitone, or to any of the other ingredients of Mysoline (these are listed in Section 6: Further information).
• have porphyria (a rare inherited disorder of metabolism) or anyone in your family has it.
Take special care with Mysoline if you:
• have ever had problems with your breathing, kidneys or liver.
• are pregnant or are trying to become pregnant (see beneath for further information)
If you go into hospital, tell the medical staff that you are taking Mysoline.
A small number of people being treated with anti-epileptics such as primidone have had thoughts of harming or killing themselves. If at any time you have these thoughts, immediately contact your doctor.
Taking other medicines
Please tell your doctor if you are taking or have recently taken any other medicines, including medicines obtained without a prescription. This is important because some medicines may affect the way Mysoline works, or Mysoline may affect the way other medicines work.
In particular, tell your doctor if you are taking any of the following:
• Other medicines used to treat epilepsy and other types of seizures (such as phenytoin, felbamate, sodium valproate, carbamazepine, ethosuxamide, oxcarbazepine, tiagabine, topiramate, zonisamide)
• Anticoagulants to prevent blood clots (such as warfarin)
• Barbiturates (such as sleeping tablets)
• Methadone (used to treat severe pain, cough, or as a substitute for morphine addiction)
• Herbal remedies containing St John's Wort
• Antibiotics (such as chloramphenicol, metronidazole, doxycycline)
• Antiviral medicines (such as nelfinavir)
• Asthma medicines (such as theophylline, montelukast)
• Hormone containing medicines (such as the oral contraceptive pill)
• Medicines used to treat high blood pressure or heart conditions (such as beta-blockers, digitoxin, losartan, nimodipine, quinidine)
• Ciclosporin (used to prevent rejection of an organ transplant and also for other diseases of the body's immune system)
• Medicines used to treat mental health problems or depression (such as clozapine, lamotrigine, mianserin, tricyclic antidepressants)
• Steroid-containing medicines
• Medicines used to treat cancer (such as cyclophosphamide, etoposide)
• Granisetron (used to treat severe nausea and vomiting)
• Medicines used during an anaesthetic for surgery (such as rocuronium, vecuronium)
• Medicines containing morphine, or similar medicines called opiates.
Mysoline may increase the toxic effect on the liver of an overdose of paracetamol.
Taking Mysoline with food and drink
Alcohol can react with Mysoline. Ask your doctor for advice if you want to drink alcohol.
Pregnancy and breast-feeding
Ask your doctor for advice before taking any medicine.
The use of Mysoline in pregnancy is associated with an increased risk of abnormalities in babies. Therefore, you must tell your doctor if you are pregnant, or trying to become pregnant because Mysoline has the potential to harm your unborn child.
Pregnant women can have reduced folic acid in their blood whilst taking Mysoline. In addition, the new born child may develop withdrawal symptoms if the mother has taken Mysoline in the late stages of pregnancy. Blood clotting problems have occurred occasionally in children born to women who were previously taking anticonvulsant drugs.
Tell your doctor if you are breast-feeding because Mysoline may cause your baby to be very sleepy. Driving and using machines
Mysoline can make you feel sleepy. If so, do not drive or operate machinery.
3. How to use Mysoline
Always take Mysoline exactly as your doctor has told you. You should check with your doctor or pharmacist if you are not sure.
Swallow the tablets whole with a drink of water.
Mysoline is normally taken twice a day. Try to take your tablets at the same time each day.

|
Age group |
Daily dose (milligrams) |
|
Adults and children over 9 years |
750 to 1500 |

If you take more Mysoline than you should
If you take more than your normal dose, contact your doctor or nearest hospital.
If you forget to take Mysoline
If you miss a dose, take it as soon as you remember. Do not take a double dose to make up for a forgotten tablet.
If you stop taking Mysoline
Do not stop taking your Mysoline, even if you are feeling well, unless your doctor tells you to. You may have become dependent on Mysoline, and therefore you could get a withdrawal reaction if you stop treatment too quickly. Mysoline treatment should be reduced gradually to prevent this.
If you have any further questions on the use of this product, ask your doctor or pharmacist.
