How it works

Primidone is an anticonvulsant that the body partly converts into phenobarbital. Both the original medicine and its by-products calm overactive electrical signalling in the brain, which lowers the chance of seizures. In essential tremor, it is thought to dampen the abnormal nerve activity that produces the shaking. It starts working gradually as the dose is built up.

Epilepsy: primidone is used for generalised tonic-clonic seizures and for focal (partial) seizures, alone or with other antiepileptic medicines.

Essential tremor: primidone is widely used to reduce the shaking of essential tremor, and the UK product information describes this use.

Standard 50 mg strength: primidone 50 mg is a commonly used tablet strength for starting treatment and for building up a daily dose that suits the patient, in epilepsy and in essential tremor.

Dosing is built up slowly and decided by your prescriber. For epilepsy, the UK product information describes starting at 125 mg at bedtime and increasing in steps over about ten days, with the total daily dose split into two or three doses. The US label describes a similar build-up, starting with 100 to 125 mg at bedtime, up to a maximum of about 2 g a day.

Building up with 50 mg tablets: for essential tremor, treatment may start at 50 mg at bedtime and rise slowly. For epilepsy, a 50 mg tablet is combined with other strengths to reach the prescribed dose. Take the tablets at the same time each day, with or without food. Always follow the leaflet in the pack and the advice of your prescriber or pharmacist.

Storage Instructions

Store the tablets in their original pack at room temperature, away from moisture and light, following any instructions on the pack. Keep out of the reach of children and do not use after the expiry date.

• Drowsiness and sleepiness
• Dizziness or unsteadiness
• Nausea or vomiting
• Headache
• Blurred or double vision, or flickering eye movements
• Rash
• Low mood, irritability or confusion
• Loss of appetite
• Tiredness

Seek urgent medical help for thoughts of harming yourself, a severe skin rash with blisters or fever, severe drowsiness or slow breathing, swelling of the face, lips or throat, or a sudden increase in seizures. Long-term use can lower folate and vitamin D levels and, rarely, cause anaemia or bone thinning, so your doctor may check your blood.

• Do not stop suddenly: stopping primidone abruptly can trigger seizures. Reduce it only gradually and under medical advice.
• First-dose effect: the first doses can cause marked sleepiness and dizziness, which is why treatment starts at a low dose.
• Alcohol and sedatives: alcohol, sleeping tablets and other sedatives add to drowsiness and can slow breathing. Avoid alcohol.
• Suicidal thoughts: antiepileptic medicines can increase thoughts of self-harm in a small number of people. Contact your doctor straight away if your mood changes.
• Contraception: primidone can make the contraceptive pill and some hormonal methods less effective. Ask your doctor about reliable methods.
• Pregnancy: primidone can harm an unborn baby and is linked with birth defects and developmental effects. Tell your doctor at once if you are pregnant or planning a pregnancy, and do not stop it yourself.
• Other medicines: primidone changes the levels of warfarin, ciclosporin, other antiepileptics and many other medicines. Tell your pharmacist about everything you take.
• Porphyria and breathing problems: do not use in acute porphyria, and use with caution in severe lung disease.
• Kidney and liver disease, older adults: lower doses may be needed.
• Breastfeeding: primidone passes into breast milk and can make a baby sleepy. Ask your doctor for advice.
• Driving: drowsiness and dizziness can occur. Do not drive or use machinery if you feel affected.
