Consumer medicine information (CMI) leaflet

Please read this leaflet carefully before you start using Bisalax Enema.

IMPORTANT

This leaflet answers some common questions about BISALAX enemas. It does not replace the advice from your doctor or pharmacist.

Keep this leaflet with the medicine. You may need to read it again.

What BISALAX enemas are used for

BISALAX contains bisacodyl as the active ingredient. Bisacodyl is a stimulant laxative and is used to provide relief from constipation or to empty the large bowel before some medical procedures, operations or X-rays.

It acts on the wall of the large bowel, encouraging bowel movements by increasing muscle contractions which push the stool mass along.

Before using it

When you must not use BISALAX

BISALAX is not suitable for some patients. You should not use this medicine if you have:

  • had an allergic reaction to bisacodyl
  • stomach cramps, colic or stomach pain
  • nausea or vomiting
  • blood in the stool
  • inflammatory bowel disease
  • a condition of the intestine called ‘ileus’
  • acute abdominal conditions such as appendicitis
  • an intestinal obstruction
  • severe dehydration
  • low potassium levels in the blood
  • haemorrhoids, or inflammation in or around the back passage (rectum) or rectal ulcers.

Before you start to use it

Tell your doctor if you are allergic to any other medicines or any foods, dyes or preservatives.

Tell your doctor if you have or have had any of the following medical conditions:

  • had any unusual or allergic reaction to laxatives
  • noticed a sudden change in bowel habits or bowel motions, that lasts longer than two weeks
  • missed a bowel motion for only a few days.

Use in children

Always ask your doctor or pharmacist before giving any medicines to children. BISALAX enemas may be used in children.

Use in pregnancy or breast feeding

BISALAX is not known to be harmful in pregnancy or while breast feeding.

However, if you are pregnant or breast feeding you should discuss with your doctor or pharmacist the risks and benefits involved, before using BISALAX.

Taking other medicines

Tell your doctor if you are taking any other medicines, including medicines that you buy without a prescription from your pharmacy, supermarket or health food shop.

Some medicines and BISALAX may interfere with each other. These include:

  • diuretics (water tablets)
  • corticosteroids
  • digoxin (medicine to treat heart problems)
  • some controlled release medicines

These medicines may be affected by BISALAX 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 more information on medicines to be careful with or to avoid while using BISALAX.

Effect on driving or alertness

BISALAX does not cause drowsiness and has no known effect on the ability to drive or operate machinery.

How to use it

BISALAX enemas may be used on their own, or in combination with BISALAX tablets.

DOSE - Adults

Depending on the condition being treated, the entire contents of an enema should be inserted into the rectum either in the afternoon, evening or morning according to the dosage guidelines below or as instructed by your doctor.

DOSE - Children

BISALAX tablets are not recommended for use in children under 6 years.

Depending on the child’s age, either half or the entire contents of an enema should be inserted into the rectum either in the afternoon, evening or morning according to the dosage guidelines below or as instructed by your doctor.

Instructions for use:

  1. Take the enema out of the refrigerator and allow it to reach room temperature before use.
  2. Shake the enema well.
  3. Take off the yellow cap from the top of the nozzle.
  4. If required, lubricate the tip with Vaseline.
  5. Lie on your left side with the left leg extended and the right leg bent, in preparation for administration of the enema.
  6. Carefully insert the applicator nozzle tip into the rectum, then press on the end of the plastic tube to squeeze the liquid out gently.
  7. Remain lying down for a couple of minutes before sitting or standing up.
  8. Discard the container after use, even if you have only used half the contents.
  9. Visit a toilet as soon as the need to pass a bowel motion occurs.

How long to use it

Follow your doctor’s or pharmacist’s instructions on how long to use BISALAX.

BISALAX should be stopped as soon as normal bowel motions have been re-established. It may not be necessary to finish the whole pack of this medicine.

Under normal circumstances, it is recommended that any laxative should not be used for longer than one week unless directed by a doctor. Prolonged use of laxatives is undesirable and may lead to dependence and further reliance on the laxative to achieve a bowel motion. This can cause a continuing cycle of constipation.

However, some patients who are no longer able to perform normal bowel motions, may need to use BISALAX enemas on a regular basis for long periods of time.

What to expect

After using BISALAX enemas, a bowel motion should normally occur within 5-15 minutes.

If you forget to use it

If you miss a dose and if you still need to use this medicine, use it as soon as you remember.

Side effects

Tell your doctor or pharmacist as soon as possible if you do not feel well while you are using BISALAX.

BISALAX helps most people with constipation but they may have unwanted side effects in some people. All medicines have side effects. Sometimes they are serious, most of the time they are not. You may need medical treatment if you get some of the side effects.

Ask your doctor or pharmacist to answer any questions you may have.

Tell your doctor or pharmacist if you notice any of the following and they worry you:

  • nausea or vomiting
  • stomach cramps, colic or pain
  • diarrhoea
  • irritation or pain around the anal area.

Tell your doctor straight away if you notice any of the following symptoms:

  • confusion
  • irritability
  • headache
  • unusual tiredness or weakness
  • muscle cramps
  • irregular heartbeat
  • breathing difficulties.

These symptoms may mean that your body has suffered a large potassium loss. This is a serious side effect. You may need urgent medical attention.

Tell your doctor or pharmacist if you notice anything else that is making you feel unwell.

Do not be alarmed by this list of side effects. You may not experience any of them.

If you use too much (overdose)

Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice if you think that you or anyone else may have used too much BISALAX. Do this even if there are no signs of discomfort or poisoning.

Signs of overdose include nausea, vomiting, severe diarrhoea and dehydration.

After using it

Storage

Keep BISALAX in a safe place, out of the reach of children. Do not use this medicine after the expiry date printed on the packaging.

Store BISALAX enemas in the original packaging at a temperature of 2°C to 8°C (Refrigerate. Do not freeze). Before use, allow the enema to reach room temperature.

Disposal

Ask your pharmacist what to do with any BISALAX you may have left over, if you no longer require them, or if you find it has passed the expiry date.

4 Clinical Particulars

4.1 Therapeutic Indications

Constipation due to confinement to bed, unaccustomed diet or change of environment. Constipation in cases of serious diseases, circulatory disturbances and metabolic disorders; occasional use in chronic constipation; bowel re-training; postoperatively in cases of haemorrhoids and anal fissures; colostomies; preparation for radiography; preparation for sigmoidoscopy or proctoscopy; preoperative preparation; postoperative care; antepartum and postpartum constipation; and preparation for delivery.

4.2 Dose and Method of Administration

The enemas can be used in conjunction with tablets. Taken at bedtime, Bisalax tablets are almost invariably effective by the following morning. When taken before breakfast, they usually produce an effect within 6-8 hours. The effects of the enema occur normally within 5 to 15 minutes.

Adults.

Preparation for X-ray examination of abdominal organs.

The day prior to the examination, 2 tablets are taken orally at lunchtime and 2 tablets in the evening. One enema is inserted into the rectum in the morning one to two hours prior to examination. No food should be given following the administration of the tablets to prevent re-accumulation of material in the caecum.

After X-ray examination.

To treat constipation due to barium contrast medium, use one enema.

Acute constipation.

Initially one enema, then 1 or 2 tablets late in the evening and 1 enema in the morning (after breakfast) for about three days.

Constipation in elderly patients.

One enema in the morning (after breakfast) on days in which defecation is desired.

Chronic constipation and bowel retraining.

By gradually increasing the interval between doses as colonic tone improves, the drug has been found to be effective in redeveloping proper bowel hygiene. There is no tendency to "rebound".

Antepartum use.

One enema immediately before delivery is anticipated.

Postpartum or postoperative constipation.

One enema to be used immediately after breakfast for two or three days.

Preparation for sigmoidoscopy proctoscopy.

For sigmoidoscopy scheduled in advance, administration of tablets the night before and one enema rectally one hour before the examination will almost invariably result in adequate preparation.

Preparation for surgery of the colon.

Two tablets at lunchtime and two tablets in the evening on the day before the operation. One enema should be inserted into the rectum on the morning of surgery.

Colostomies.

Two tablets the night before inserted into the colostomy opening in the morning will frequently make irrigations unnecessary and in other cases will expedite the procedure.

Children.

Preparation for X-ray examination of abdominal organs.

Under 1 year.

Half an enema the night before the examination and half an enema in the morning on the day of the examination.

1 to 3 years.

One enema the night before the examination and one enema in the morning of the day of the examination.

3 to 6 years.

One enema in the afternoon of the day before the examination and one enema in the morning of the day of the examination.

(Note: Bisalax tablets are not recommended for use in children under 6 years of age.)

Advice to patients.

If you have noticed a persistent change in bowel habits, consult a physician before using a laxative.
Laxative products should not be used longer than one week unless directed by a physician (see Section 4.4 Special Warnings and Precautions for Use).
Rectal bleeding or failure to have a bowel movement after use of a laxative may indicate a serious condition. Discontinue use and consult a physician.
Bisalax enemas should be administered rectally when required (see Section 4.2 Dose and Method of Administration). Pull off plastic cap from end of nozzle, insert nozzle in rectum and squeeze tube to administer contents. The nozzle of the Bisalax enema may be coated with a lubricant to aid insertion.

4.3 Contraindications

Bisacodyl has the same contraindications as other laxatives.
All laxatives are contraindicated in patients with cramps, colic, nausea, vomiting or other symptoms as in appendicitis, inflammatory bowel disease, acute abdominal situations such as ileus, intestinal obstruction or any other undiagnosed abdominal pain.
Bisalax is also contraindicated in dehydration, hypokalaemia, hypersensitivity to bisacodyl or to any of the excipients.
Bisalax enemas are contraindicated in patients with anal fissure, ulcerative proctitis with mucosal damage and ulcerated haemorrhoids.

4.4 Special Warnings and Precautions for Use

Prolonged use of laxatives may lead to dependence, chronic constipation and loss of bowel function. "Cathartic colon" with atony, dilatation and resemblance of ulcerative colitis or proctitis, is also possible.
In addition, continued use of irritant laxatives may produce serious loss of electrolytes, especially potassium and result in disturbances of cardiac function, diarrhoea, dehydration, malabsorption and protein losing enteropathy.
Syncope has been reported during the use of Bisalax. The event could be related to defecation syncope or to a vasovagal response to abdominal pain.

Use in the elderly.

No data available.

Paediatric use.

Children should not make frequent use of Bisalax unless medically supervised.

Effects on laboratory tests.

No data available.

4.5 Interactions with Other Medicines and Other Forms of Interactions

Concomitant use of diuretics or systemic corticosteroids may increase the risk of electrolyte imbalance. This interaction is significant only if excessive doses of Bisalax are taken.
By increasing the motility of the small intestine and speeding the passage, Bisalax can alter the bioavailability of some drugs absorbed mainly from the small intestine such as digoxin and controlled release formulations.

4.6 Fertility, Pregnancy and Lactation

Effects on fertility.

No data available.
(Category A)
Category A of Australian Categorisation of Risk of Drug Use in Pregnancy.
There is no contraindication to use of Bisalax by nursing mothers, however as bisacodyl is excreted in the breast milk in low quantities, the drug should only be used during lactation when clearly indicated.

4.7 Effects on Ability to Drive and Use Machines

The effects of this medicine on a person's ability to drive and use machines were not assessed as part of its registration.

4.8 Adverse Effects (Undesirable Effects)

Bisacodyl is well tolerated and side effects are rare. However, side effects in the form of diarrhoea, local rectal irritation, proctitis, slight indisposition, epigastralgia, tenesmus, nausea, abdominal pain and cramping have been reported. A possible colic should be treated with atropine derivatives.
Rare cases of vomiting, mild transient skin reactions and hypersensitivity reactions including angioedema and anaphylactoid reactions have also been described.

Reporting suspected adverse effects.

Reporting suspected adverse reactions after registration of the medicinal product is important. It allows continued monitoring of the benefit-risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions at http://www.tga.gov.au/reporting-problems.

4.9 Overdose

For information on the management of overdose, contact the Poisons Information Centre on 131126 (Australia).

5 Pharmacological Properties

5.1 Pharmacodynamic Properties

Mechanism of action.

The precise mode of action is unknown. Bisacodyl is a contact laxative. Its action is restricted mainly to the colon; the motility of the small intestine is not appreciably influenced. Bisacodyl acts locally in the gastrointestinal tract, stimulating sensory nerve endings in the colonic mucosa to produce parasympathetic reflexes resulting in increased peristaltic contractions of the colon. Local axon reflexes as well as segmental reflexes are initiated in the region of contact and contribute to the widespread peristaltic activity producing evacuation. For this reason, bisacodyl may be employed satisfactorily in patients with ganglionic blockage or spinal cord damage (paraplegia, poliomyelitis etc).

Clinical trials.

No data available.

5.2 Pharmacokinetic Properties

Although previously thought not to be absorbed from the digestive tract, recent studies have shown that up to 5% of an oral dose of bisacodyl may be absorbed in man. Bisacodyl is excreted mainly in faeces, and partly in urine as the glucuronide. When taken on an empty stomach, bisacodyl tablets will exert their effect in 6 to 8 hours. When taken with food, the effect of the tablets will occur in 10 to 12 hours.

5.3 Preclinical Safety Data

Genotoxicity.

No data available.

Carcinogenicity.
