What is Mysoline 250mg used for?
Mysoline 250mg contains primidone, an anti-epileptic medicine used to control grand mal seizures (tonic-clonic seizures causing loss of consciousness and convulsions), focal seizures (starting in one area of the brain), and myoclonic jerks (sudden, brief muscle jerks). Primidone is also used to treat essential tremor — an involuntary shaking of the hands or arms that is not caused by epilepsy. It is one of the older epilepsy medicines but remains effective and is still widely used in some settings.
How does primidone work to control seizures?
Primidone works in two ways. First, it acts directly on nerve cells in the brain to reduce their excitability, helping to prevent abnormal electrical firing that causes seizures. Second — and importantly — the body converts primidone into two active substances in the liver: phenobarbital and PEMA (phenylethylmalonamide). Both of these also have anti-seizure effects, so primidone effectively acts as three medicines in one. Phenobarbital, one of the breakdown products, is thought to contribute significantly to the anti-epileptic effect.
How should Mysoline 250mg be taken?
Primidone treatment is started at a very low dose — often just 125mg (half a 250mg tablet) at bedtime for the first week — and gradually increased over several weeks to minimise sedation, which is very pronounced when treatment begins. The usual maintenance dose for epilepsy is 500–1500mg per day in 2–3 divided doses. For essential tremor, lower doses are often effective. Always follow your neurologist's dose schedule. Take it with food if you experience stomach upset. Avoid stopping suddenly — this must be done gradually.
Why does primidone cause so much drowsiness at first?
The marked sedation when starting primidone is largely due to the sudden exposure of the body to primidone itself, before it builds up tolerance. As the body adjusts over 1–2 weeks, the sedation reduces significantly for most people. Starting at a very low dose (a quarter or half tablet at bedtime) and increasing very slowly week by week — rather than starting at a full therapeutic dose — greatly reduces the severity and duration of this initial drowsiness. Most people find it entirely manageable with a gradual start.
Can primidone be used for essential tremor?
Yes — primidone is one of two main medicines used for essential tremor (the other being propranolol). It is very effective at reducing the hand tremor associated with this condition, which can be very disabling in everyday activities like writing, eating, or using tools. The dose used for tremor is usually lower than for epilepsy. Benefits are typically noticed within days of reaching an effective dose. Like all tremor medicines, it controls symptoms rather than curing the underlying condition, so ongoing treatment is usually needed.
How does primidone compare to phenobarbital for epilepsy?
Primidone is closely related to phenobarbital — it converts into phenobarbital in the body, which contributes to most of its anti-epileptic effect. Primidone is generally considered slightly more effective than phenobarbital for some seizure types because of its own direct action before it is converted. However, primidone causes more initial sedation than phenobarbital. Both are older medicines with more side effects and interactions than newer anti-epileptics. Many neurologists prefer newer options for newly diagnosed epilepsy, but primidone remains in use for established patients responding well.
Can primidone be taken during pregnancy?
Primidone (which converts to phenobarbital in the body) carries risks during pregnancy, including an increased risk of birth defects — particularly heart defects and cleft lip/palate — similar to other barbiturate-type medicines. It is not a first choice for women of childbearing age. Primidone also causes low vitamin K levels in newborns if taken during late pregnancy, which can cause bleeding problems in the baby at birth — vitamin K is given to the newborn as a precaution. Women on primidone who are pregnant or planning a pregnancy must urgently discuss their medicine with their neurologist.
What are the side effects of primidone?
The most significant side effect when starting primidone is severe sedation and dizziness — this is why treatment must begin at a very low dose and increase slowly. Once established on a maintenance dose, ongoing side effects of primidone include tiredness, dizziness, nausea, and cognitive slowing. Long-term use can cause effects similar to phenobarbital: vitamin D deficiency leading to bone thinning, and occasionally mood changes. Like phenytoin, primidone can affect folate metabolism, so folic acid supplements may be recommended for women of childbearing age.
Does primidone interact with other medicines?
Primidone has many interactions because it converts to phenobarbital, which is a powerful liver enzyme inducer. This means it significantly speeds up the breakdown of many other medicines — including hormonal contraceptives (making the pill less reliable), warfarin, some antibiotics, other epilepsy medicines, and certain antidepressants. Many medicines can also alter primidone or phenobarbital blood levels. Blood level monitoring of both primidone and phenobarbital is used to manage these interactions. Always keep your doctor and pharmacist informed of every medicine you take.
Who should not take primidone?
Primidone should not be taken by people with a known sensitivity to phenobarbital, as they are closely related. It should be avoided or used with great caution in people with porphyria (a metabolic disorder), severe liver or kidney disease, and respiratory depression. It is generally not recommended as a first-line treatment for women of childbearing age due to pregnancy risks. Elderly patients are more sensitive to its sedating effects and are at higher risk of falls. People with depression should use primidone cautiously as it can worsen low mood.

Can primidone be stopped suddenly?
No — primidone must never be stopped abruptly. Sudden discontinuation can trigger severe withdrawal seizures, as both primidone and its active metabolite phenobarbital are involved in controlling brain excitability. If you stop suddenly, the brain can become excessively excitable, causing dangerous withdrawal seizures. If you need to stop primidone, your neurologist will plan a very slow tapering schedule — reducing the dose gradually over weeks or months. Never reduce or stop your dose without first consulting your epilepsy specialist.
