1.  hat Epanutin is and what it
is used for
Epanutin is one of a group of medicines called antiepileptic drugs; these medicines are used to treat
Epanutin can be used to control epilepsy, to control
or prevent seizures during or after brain surgery or
severe head injury. Epanutin can also be used to
treat trigeminal neuralgia (facial nerve pain).
You should consult your doctor if you are unsure
why you have been given Epanutin 30mg/5ml Oral

2. Before you take Epanutin
Do not take Epanutin

•  you are allergic (hypersensitive) to Phenytoin, or
any of the other ingredients of Epanutin 30mg/5ml

Take special care with Epanutin

Medicines are not always suitable for everyone. Your
doctor needs to know before you take Epanutin if
you suffer from or have suffered in the past from any
of the following conditions:
• Liver disease.
• Porphyria (an inherited disease that affects
haemoglobin biosynthesis).
A small number of people being treated with
antiepileptics such as phenytoin have had thoughts
of harming or killing themselves.
If at any time you have these thoughts,
immediately contact your doctor.
Potentially life-threatening skin rashes (Stevens
Johnson syndrome, toxic epidermal necrolysis) have
been reported with the use of Epanutin, appearing
initially as reddish target-like spots or circular
patches often with central blisters on the trunk.
Additional signs to look for include ulcers in the
mouth, throat, nose, genitals and conjunctivitis (red
and swollen eyes). These potentially life-threatening
skin rashes are often accompanied by flu-like
symptoms. The rash may progress to widespread
blistering or peeling of the skin. The highest risk for
occurrence of serious skin reactions is within the first
weeks of treatment. If you have developed StevensJohnson syndrome or toxic epidermal necrolysis
with the use of Epanutin, you must not be re-started
on Epanutin at any time.
If you develop a rash or these skin symptoms, stop
taking Epanutin, seek urgent advice from a doctor

and tell him that you are taking this medicine.
Consult your doctor before discontinuing Epanutin.
If you suddenly stop taking this medicine you may
have a seizure.
This risk of these serious skin side effects may be
associated with a variant in genes in a subject with
Chinese or Thai origin. If you are of such origin and
have been tested previously carrying this genetic
variant (HLA-B*1502), discuss this with your doctor
before taking Epanutin.

Shake the bottle vigorously before you
measure your dose. Always use a medicine spoon
or measure.
It is best to take Epanutin at the same time each day.

spoonfuls of Suspension) either as a single or divided
dose. Occasionally higher doses are needed.

depends on their weight (5mg per day for every kg
they weigh) and is given as a divided dose, twice a
day. The dose is then adjusted up to a maximum of
300mg a day (10 five-ml spoonfuls of Suspension).

The dose of Epanutin for elderly patients who may
be taking other medicines may also need careful
consideration and adjustment by their doctor.

told you. You should check with your doctor or
pharmacist if you are still not sure.

you remember unless it is time for your next dose.

you to. If you suddenly stop taking this medicine you
