How Phenobarbitone Injection works

Phenobarbitone steadies the electrical activity in the brain, making a seizure less likely to start and spread.

How to take Phenobarbitone Injection

This is given by a doctor or a nurse. Do not attempt to inject it yourself unless you have been trained and told to. Follow the dose and the duration written on your prescription.

Take it exactly as your doctor prescribed. Do not change the dose or stop early on your own.

Missed dose and overdose

If you miss a dose

Take it as soon as you remember. If your next dose is almost due, skip the one you missed — never take two doses together to catch up.

If you take too much

An overdose of this medicine can cause deep unconsciousness, slowed breathing and dangerous heart rhythm disturbance. Do not wait for symptoms to appear — go to the nearest emergency department and take the pack or strip with you.

Side effects of Phenobarbitone Injection

Most side effects of Phenobarbitone are mild and settle as the body adjusts. Reported side effects include:

• Drowsiness
• Dizziness
• Unsteadiness
• Nausea
• Double vision
• Mood change
• Tremor

Stop the medicine and seek help immediately for a rash, swelling of the face or lips, wheezing or difficulty breathing. Tell your doctor about any side effect that persists or worries you.

Safety advice for Phenobarbitone Injection

Warnings and precautions

Never stop or change an anti-epileptic on your own. Stopping abruptly can cause prolonged, dangerous seizures. Sodium valproate and divalproex must not be used by anyone who is pregnant or could become pregnant unless a specialist has confirmed there is no alternative — they cause serious birth defects and developmental problems. Effective contraception is essential. Seek urgent care for any rash, especially in the first weeks — a rash with fever, blistering or peeling can be life-threatening. Report yellowing of the eyes or skin, persistent vomiting, unusual bruising or severe tiredness at once. Tell your doctor about any change in mood or any thoughts of harming yourself. Take the same brand each time unless your neurologist has agreed to a change; switching can alter seizure control.

Do not take Phenobarbitone if

Not for anyone with a known allergy to this medicine or to any ingredient in the pack. Valproate-containing medicines are contraindicated in pregnancy for epilepsy unless no alternative exists, and in all women of childbearing potential without a pregnancy prevention programme. Several are not suitable in significant liver disease.

Interactions with other medicines

This group interacts very widely, including with contraceptives, blood thinners and other anti-epileptics. Give your doctor a full list of what you take. Hormonal contraception may become unreliable — ask your doctor which method to use.

How to store Phenobarbitone Injection

Store as printed on the carton — some injections need refrigeration and must not be frozen. Keep out of the reach of children.

Expert advice for Phenobarbitone Injection

Take it at the same times every day; a missed dose is a common trigger for a seizure. Keep a seizure diary and take it to your appointments. Tell your doctor before planning a pregnancy — the regimen may need to be changed well in advance. Do not drive until you meet the legal seizure-free period and your doctor agrees.
