in the past from any of the following conditions:
- Low blood pressure or heart failure
- Liver disease where the dosage may need to be adjusted
- Kidney disease
- Porphyria (an inherited disease that affects haemoglobin
- Heart rhythm problems (Phenytoin Accord can treat
some rhythm problems, but can make others worse)
- Alcohol dependence.
You should be administered Phenytoin Accord with
caution if you suffer from kidney or liver problems.
A small number of people being treated with antiepileptics
such as phenytoin sodium 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 phenytoin, 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
Stevens-Johnson syndrome or toxic epidermal necrolysis
with the use of phenytoin injection, you must not be
re-started on phenytoin injection at any time.
If you develop a rash or these skin symptoms, stop taking
Phenytoin Accord, seek urgent advice from a doctor and tell
him that you are taking this medicine. Consult your doctor
before discontinuing Phenytoin Accord. If you suddenly
stop taking this medicine you may have a seizure.
If you are taking phenytoin at the same time as you
receive radiation therapy to your head and the dose of
another medication called corticosteroids is reduced, you
may more likely to develop a severe skin rash called
erythema multiform or one that causes blistering called
Stevens Johnson Syndrome or Toxic Epidermal Necrosis
(see Possible Side Effects in section 4).
Other medicines and Phenytoin Accord
Tell your doctor if you are taking, have recently taken or
might take any other medicines, including medicines
obtained without a prescription.

works, or Phenytoin Accord itself can reduce the
effectiveness of other medicines taken at the same time.

dicoumarol, amiodarone, reserpine, digitoxin, digoxin,

3. How Phenytoin Accord is given
You will be in hospital when you are given Phenytoin
Phenytoin Accord will be either injected into one of your
large veins (intravenously) or into your muscle
(intramuscularly). When given intravenously, Phenytoin
Accord must be diluted.
The dose and concentration of the solution of Phenytoin
Accord you are given will be decided by your doctor and will
be written as the equivalent dose of phenytoin sodium (PE).
The dose will be as mg per dose if given as an injection or
mg per ml of solution if given as an infusion (drip).
Sometimes it is necessary to give Phenytoin Accord into
your muscle if you cannot continue to take it by mouth.
This is not normally continued for longer than one week.
When switching from oral phenytoin to intramuscular
injection, the dose needs to be increased by
approximately 50%. When switching back to oral
Phenytoin, the dose should be reduced to half the original
oral dose for the same period of time that the
intramuscular injection was given. This is because
phenytoin continues to be released from your muscles for
some time after the injections have been given.
Severe epileptic seizure or fits (Status Epilepticus)
A dose of 10 to 15 mg per kg of body weight is given
intravenously at a rate not exceeding 50 mg per minute in
adults. This is followed by more phenytoin given every 6
to 8 hours either by injection or by mouth.
If phenytoin does not stop your seizures, other treatments
will be tried.
Cardiac arrhythmias (variations to normal heartbeat)
A dose of 3.5 to 5 mg per kg of body weight is given
intravenously, at a rate not exceeding 50 mg per minute.
This may be repeated a second time.
A dose of 100 to 200 mg may be given into your muscle
(intramuscularly) approximately every 4 hours during
surgery and for two to three days afterwards to prevent
seizures. This dosage may then be reduced to a
maintenance dose of 300 mg daily and adjusted
according to your blood levels.
Due to decreased clearance of Epanutin, lower or less
frequent dosing may be needed. The dose of Epanutin for
elderly patients who may be taking other medicines may
also need careful consideration and adjustment by their
Kidney or liver problems
Make sure your doctor knows if you have liver or kidney
problems as you may need your dose adjusted
Children and adolescents
No dosage adjustment is required, but children tend to
breakdown the medicine faster than adults and this may
mean that your doctor has to change the number or
timing of the phenytoin doses.
Neonates (very young babies)
The starting dose is usually 15 to 20 mg per kg of baby
weight. Intravenous Phenytoin Accord should not be given
to neonates at a rate faster than 1 to 3 mg per kg body
weight per minute.
Intravenous phenytoin is more reliably absorbed than oral
phenytoin in very young babies.
If you are given more Phenytoin Accord than you
Phenytoin is dangerous in overdose. If you think you have
been given too much phenytoin, contact your doctor

product, ask your doctor, pharmacist or nurse.
