Magnesium Valproate is used to treat epilepsy, bipolar disorder, and to prevent migraine headaches. It belongs to a class of medicines called anticonvulsants, which help stabilise electrical activity in the brain.
Magnesium Valproate is commonly used for:
• Epilepsy: Helps control and prevent different types of seizures by stabilising electrical activity in the brain.
• Bipolar disorder: Helps manage manic episodes and stabilise mood in people with bipolar disorder.
• Migraine prevention: Reduces the frequency of migraine attacks when taken regularly, as advised by your doctor.
• Mood stabilisation: Used to help manage mood swings associated with bipolar disorder.
Nausea and vomiting
Diarrhoea
Abdominal pain
Dizziness
Drowsiness
Magnesium Valproate works by calming overactive electrical activity in the brain.
Nerve cells in the brain communicate using electrical signals. In epilepsy, abnormal, excessive electrical activity in the brain can trigger seizures. Magnesium Valproate increases the levels of a calming brain chemical called gamma-aminobutyric acid (GABA), which reduces the excitability of nerve cells and helps prevent seizures.
It also has direct effects on ion channels in nerve cells, which further helps stabilise electrical activity in the brain.
In bipolar disorder, this calming effect on nerve cell activity is thought to help stabilise mood swings, while a similar mechanism is believed to reduce the frequency of migraine attacks by calming overactive nerve pathways involved in migraine.
