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 Dilantin 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 Dilantin Suspension
Store below 30°C, away from direct sunlight. Do not freeze. Once opened, use it within the period printed on the pack. Keep out of the reach of children.
Expert advice for Dilantin Suspension
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.
