Consumer Medicine Information

What is in this leaflet

This leaflet answers some common questions about Lofenoxal. It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.
All medicines have risks and benefits. Your doctor has weighed the risks of you taking Lofenoxal against the benefits they expect it will have for you.
If you have any concerns about taking this medicine, ask your doctor or pharmacist.
Keep this leaflet with the medicine.
You may need to read it again.

What LOFENOXAL is used for

Lofenoxal is used along with other measures for the treatment of acute or chronic diarrhoea.
Lofenoxal contains the active ingredients diphenoxylate hydrochloride and atropine sulfate. Diphenoxylate reduces diarrhoea by slowing down the movements of the intestines. Because diphenoxylate may be abused by taking it in doses that are larger than prescribed, a small amount of atropine sulfate is included in Lofenoxal. This causes unpleasant effects if larger than normal doses are taken and discourages abuse.
Lofenoxal is only available with a doctor’s prescription.

Before you take LOFENOXAL

When you must not use it

Do not take Lofenoxal if:
You are allergic to diphenoxylate, atropine or any of the tablet ingredients listed at the end of this leaflet
If you have an allergic reaction you may get a skin rash, difficulty in breathing, hayfever or faintness.
You have jaundice
You have diarrhoea caused by pseudomembranous enterocolitis
This is a potentially serious infection of the gut, which may occur during or up to several weeks following antibiotic treatment.
You have an inflammatory bowel disease such as ulcerative colitis or Crohn’s disease
You have bacterial colitis or amoebic colitis.
You are breastfeeding.
You should use an alternative form of infant feeding while you are taking Lofenoxal.
Lofenoxal passes into breast milk, so if you take Lofenoxal while breastfeeding, your baby may have some effects from it.
Lofenoxal is not recommended for children less than 12 years old.
Children, especially very young children, are very sensitive to the effects of Lofenoxal.
Lofenoxal must be kept out of the reach of children, since accidental overdose in children may result in serious breathing difficulties, or even death.
Do not use tablets after the use by date, which appears on the label after the letters “EXP”.
They may have no effects at all, or an entirely unexpected effect if you use them after the expiry date.
Do not use Lofenoxal if the packaging is torn or shows signs of tampering.
Do not use Lofenoxal to treat any other complaints unless your doctor says to.
Do not give this medicine to anyone else, even if their symptoms seem similar to yours.

Before you start to use Lofenoxal

Tell your doctor if:
You are allergic to any other medicines, or foods, dyes or preservatives
You have any other medical conditions, especially:
Liver disease, jaundice
Kidney disease
Down’s syndrome
History of drug abuse
You are taking any other medicines, including medicines that you buy without a prescription from a pharmacy, supermarket or health food shop.
Some of the medicines that may interfere with Lofenoxal include:
Tranquillisers – medicines used to produce calmness, treat anxiety or help you sleep
Antidepressants – medicines used to treat depression, such as monoamine oxidase inhibitors (MAOI)
Barbiturates – medicines used to treat epilepsy and to help you sleep.
These medicines may be affected by Lofenoxal or may affect how well it works. You may need to take different amounts of your medicine or you may need to take different medicines. Your doctor or pharmacist has a more complete list of medicines to avoid while taking Lofenoxal.
Do not drink alcohol while taking Lofenoxal.
Tell your doctor if you become pregnant while you are taking Lofenoxal.
You should not take Lofenoxal near or at the time of giving birth, because diphenoxylate is chemically related to medicines which can slow down the breathing of newborn infants.

How to take Lofenoxal

Follow your doctor’s or pharmacist’s instructions on how much Lofenoxal to take and for how long to take it.
The usual starting dose of Lofenoxal is 2 tablets, three or four times a day, until the diarrhoea is under control.
The dose is then usually reduced, so that you are taking just enough tablets to control the diarrhoea. This may be as few as 2 tablets a day.
The usual maximum dose is 8 tablets in a day (24 hours).
Your doctor may want you to stop taking Lofenoxal when your bowel movements return to normal.
If your diarrhoea contains blood or lasts for more than 2 days, tell your doctor.

If you take too much (overdose)

Immediately telephone your doctor, pharmacist or Poisons Information Centre (telephone number: 131126) for advice, or go to Casualty at your nearest hospital, if you think that you or anyone else may have taken a large number of Lofenoxal tablets. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
Keep telephone numbers for these places handy.
If you think someone has taken an overdose of Lofenoxal, or if a child has accidentally taken Lofenoxal tablets, you should get medical help immediately.
Signs that may indicate an overdose are: at first, dryness of the skin and mouth, widening of the pupils of the eye, restlessness, flushing, high temperatures and rapid heartbeat, followed by lack of energy or coma, poor reflexes, constant movements of the eyeballs, pinpoint (small) pupils and slow, shallow breathing (respiratory depression). Sometimes respiratory depression may not occur straight away and may develop as late as 30 hours after an overdose. Patients should be watched for at least 48 hours, preferably in hospital.

While you are using Lofenoxal

Things you must do

Use Lofenoxal exactly as your doctor has prescribed.
Tell all doctors, dentists and pharmacists who are treating you that you are taking Lofenoxal.
Drink plenty of liquids, such as an oral rehydration solution.
Drinking plenty of liquids makes sure you do not become dehydrated (lose too much liquid from your body). If you have become very dehydrated, see your doctor to make sure this is corrected, before taking Lofenoxal.
Eat as little as possible for the first few days.
Eat only plain, bland foods, such as unbuttered toast, plain biscuits, boiled potatoes, rice or pasta. Gradually return to your normal diet when the diarrhoea has stopped.
Be careful driving or operating machinery until you know how Lofenoxal affects you.
Lofenoxal can make some people drowsy or dizzy. Make sure you know how you react to Lofenoxal before you drive a car or operate machinery.

Things you must not do

Do not give this medicine to anyone else, even if their symptoms seem similar to yours.
