The product should be taken during the day at least ½ to 1 hour before or after intake of other medicines and should not be taken immediately before going to sleep.

Effects may take 12-24 hours.

When preparing the product for administration, it is important to try to avoid inhaling any of the powder in order to minimize the risk of sensitisation to the active ingredient.

4.3. Contraindications

Hypersensitivity to ispaghula husk, mebeverine or to any of the excipients listed in section 6.1. (See Section 4.4).

Patients with a sudden change in bowel habit that has persisted more than two weeks.

Undiagnosed rectal bleeding and failure to defecate following the use of a laxative.

Patients suffering from abnormal constrictions in the gastro-intestinal tract, with diseases of the oesophagus and cardia, potential or existing intestinal blockage (ileus), paralysis of the intestine or megacolon.

Patients who have difficulty in swallowing or any throat problems.

4.4. Special warnings and precautions for use

The use is not recommended in children below 12 years of age due to insufficiency data on efficacy.

Laxative bulk producers should be used before using other purgatives if change of nutrition is not successful.

Fybogel Mebeverine should not be taken in the dry form and should always be taken mixed with fluid (5 fluid ounces or 150 mL of water or other liquid per sachet).

Gastrointestinal obstruction or impaction have been reported with hydrophilic mucilloid preparations when taken with insufficient liquid, contrary to administration instructions.

Ispaghula husk should not be used by patients with faecal impaction and symptoms such as abdominal pain, nausea and vomiting unless advised by a doctor because these symptoms can be signs of potential or existing intestinal blockage (ileus).

If abdominal pain occurs or in cases of any irregularity of faeces, the use of ispaghula husk should be discontinued and medical advice must be sought.

When taken with inadequate fluid amounts, bulk forming agents can cause obstruction of the throat and oesophagus with choking and intestinal obstruction. Symptoms can be chest pain, vomiting, or difficulty in swallowing or breathing.

The treatment of debilitated patients and / or elderly patients requires medical supervision.

In order to decrease the risk of gastrointestinal obstruction (ileus) ispaghula husk should not be used together with medicinal products known to inhibit peristaltic movement (e.g. opioids) and then only under medical supervision (see section 4.5).

This product should not be taken immediately before going to bed as reduced gastric motility may impair intestinal passage and cause obstruction.

This medicine contains 16 mg aspartame in each unit dose (sachet). Aspartame is a source of phenylalanine. It may be harmful if you have phenylketonuria (PKU), a rare genetic disorder in which phenylalanine builds up because the body cannot remove it properly.

Consult your doctor if you have developed new symptoms, or if your symptoms worsen, or if they do not improve after two weeks of treatment.

Warning on hypersensitivity reactions: In individuals with continued occupational contact to powder of Plantago ovata seeds (e.g. healthcare workers and caregivers) allergic sensitisation may occur due to inhalation; this is more frequent in atopic individuals. This sensitisation usually leads to hypersensitivity reactions which could be serious (See 4.8).

It is recommended to assess clinically the possible sensitisation of individuals at risk and, if justified, to perform specific diagnostic tests.

In case of proven sensitisation leading to hypersensitivity reactions, exposure to the product should be stopped immediately and avoided in the future (See 4.3).

This medicine contains 2.5 mmol (or 97.6 mg) potassium per sachet. To be taken into consideration by patients with reduced kidney function or patients on a controlled potassium diet.

The medicinal product contains 2.56 mmol (or 58.9 65mg) sodium per sachet, equivalent to 2.9% of the WHO recommended maximum daily intake of 2g sodium for an adult. To be taken into consideration by patients on a controlled sodium diet.

Mebeverine should be used with care in patients with hepatic or renal impairment, and those with cardiac disorders such as heart block.

4.5. Interaction with other medicinal products and other forms of interaction

Enteral absorption of concomitantly administered medicines such as minerals (such as calcium, iron, or zinc), vitamins (B12), cardiac glycosides, coumarin derivatives, carbamazepine and lithium may be delayed. For this reason, the product should not be taken ½ to 1 hour before or after intake of other medicinal products.

Diabetic patients should take ispaghula husk only under medical supervision because adjustment of anti-diabetic therapy may be necessary.

Use of ispaghula husk concomitantly with thyroid hormones requires medical supervision because the dose of the thyroid hormones may have to be adjusted.

In order to decrease the risk of gastrointestinal obstruction, ispaghula husk should only be used together with medicinal products known to inhibit peristaltic movement (e.g. opioids, opioid-like agents and loperamide) if under medical supervision.

4.6. Fertility, pregnancy and lactation

Pregnancy

This product should be avoided during pregnancy.

There are limited data (less than 300 pregnancy outcomes) from the use of ispaghula husk in pregnant women. There are no or limited amounts of data from the use of mebeverine in pregnant women. Animal studies are insufficient with respect to reproductive toxicity (see section 5.3a).

Breast-feeding

This product should not be used in breast-feeding.

Mebeverine or metabolites have been identified in breastfed newborns/infants of treated women. There is insufficient information on the effects of Mebeverine in newborns/infants.

Fertility

There are no clinical data on male or female fertility.

4.7. Effects on ability to drive and use machines

None known

4.8. Undesirable effects

The list of the following adverse effects relates to those experienced with ispaghula husk and mebeverine hydrochloride at OTC doses, in short term use. In the treatment of chronic conditions, under long-term treatment, additional adverse effects may occur.

Special attention should be given to individuals manipulating the powder formulations routinely (see section 4.4). The frequency is not known.

Adverse events which have been associated with ispaghula husk or mebeverine are given below, tabulated by system organ class and frequency. Frequencies are defined as: Very common (≥1/10); Common (≥1/100 and <1/10); Uncommon (≥1/1000 and <1/100); Rare (≥1/10,000 and <1/1000); Very rare (< 1/10,000); Not known (cannot be estimated from the available data).

Description of Selected Adverse Reactions

1 Including rash, urticaria, anaphylactic reaction, pruritus, bronchospasm, rhinitis and angioedema.

2 Ispaghula/psyllium husk contains potent allergens. The exposure to these allergens is possible through oral administration, contact with the skin and, in the case of powder formulations, also by inhalation. As a consequence to this allergic potential, individuals exposed to the product can develop hypersensitivity reactions such as rhinitis, conjunctivitis, bronchospasm and in some cases, anaphylaxis. Cutaneous symptoms such as exanthema and/or pruritus have also been reported.

3 Flatulence and abdominal distension (bloating) may be experienced during the first few days of treatment, but should diminish during continued treatment. Abdominal distension and risk of intestinal or oesophageal obstruction and faecal impaction may occur, particularly if swallowed with insufficient fluid.

Reporting of Suspected Adverse Reactions

Reporting suspected adverse reactions after authorisation 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 via the Yellow card Scheme at www.mhra.gov.uk/yellowcard, or search for MHRA Yellow Card in the Google Play or Apple App Store.

4.9. Overdose

In the event of overdose, conservative measures should be taken.

Symptoms

Overdose with ispaghula husk may cause abdominal discomfort, flatulence and intestinal obstruction. Mebeverine can have neurological or cardiovascular effects in overdose.

Management

Adequate fluid intake should be maintained, and management should be symptomatic.
