The use in children and adolescents under 12 years of age has not been established due to lack of adequate data.

Patients taking liquorice medication should not take other liquorice containing products as serious adverse events may occur such as water retention, hypokalemia, hypertension, cardiac rhythm disorders.

Liquorice medication should be used with caution in patients affected by hypertension, kidney diseases, liver or cardiovascular disorders or hypokalemia as they are more sensitive to the adverse effects of liquorice.

If symptoms worsen or persist for more than one week, a doctor or a qualified healthcare practitioner should be consulted.

If dyspnoea, fever or purulent sputum occurs, a doctor or a qualified healthcare practitioner should be consulted.

4.5 Interaction with other medicinal products and other forms of interaction

Liquorice root may counteract antihypertensive action of prescribed medications.

Not to be used concomitantly with thiazide diuretics, cardiac glycosides, corticosteroids, stimulant laxatives or other medications which may aggravate electrolyte imbalance.

In view of the potential for Squill to interact with other medicines administered concurrently, the product should not be taken with digoxin or any medicines for a heart condition.

Contains alcohol and should therefore be avoided in patients taking other medication known to interact with alcohol e.g. Metronidazole.

No studies on the effect on the ability to drive or operate machines have been performed.

This product contains alcohol (see section 2)

4.8 Undesirable effects

Adverse effects of both squill and ipecacuanha include nausea and vomiting caused by their irritant effect on the gastrointestinal tract; squill can also cause diarrhoea. Absorption of emetine known to accumulate in muscle after ingestion of larger doses of ipecacuanha may interfere with muscle fibre contractility of heart muscle.

The frequency is not known.

If other adverse reactions not mentioned above occur, a doctor or a qualified healthcare practitioner should be consulted.

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:

4.9 Overdose

The symptoms of overdose of squill and ipecacuanha include nausea and vomiting. Treatment of overdose would depend upon the symptoms, cardiac irregularities, which may be caused by squill, may be treated by emesis or aspiration and lavage. In cases of severe cardiac arrhythmias, potassium and/or anti-arrhythmic agents may be given. Prolonged vomiting may be a symptom of overdose of ipecacuanha alkaloids, which may be controlled by intramuscular injection of 25 -50mg of chlorpromazine or of a comparable dose of a related phenothiazine; fluid and electrolyte imbalance should also be corrected.

Cases of overdose with liquorice root have been reported with prolonged use (more than 4 weeks) and/or intake of high amount of liquorice, with symptoms such as water retention, hypokalaemia, hypertension, cardiac rhythm disorders, hypertensive encephalopathy.

5. Pharmacological properties
5.1 Pharmacodynamic properties

Not required as per Article 16c (1)(a)(iii) of Directive 2001/83/EC as amended.

5.2 Pharmacokinetic properties

Not required as per Article 16c (1)(a)(iii) of Directive 2001/83/EC as amended.

5.3 Preclinical safety data

Tests on reproductive toxicity, genotoxicity and carcinogenicity have not been performed.

A study has shown that 18β-glycyrrhetinic acid crosses through the placental barrier and can be detected in the rat foetuses. Following feeding of dams with 100 mg 18β-glycyrrhetinic acid/kg/day commencing on the 13th day of gestation, on the 17th, 19th and 21st days of gestation the maternal plasma 18β-glycyrrhetinic acid concentrations were approximately 100 μg/ml, whereas the foetal concentrations were 5, 18 and 32 μ/ml, respectively.

In developmental toxicity studies, glycyrrhizin (ammonium salt) exhibited some embryotoxicity to the developing rat foetus, but the foetal effects were considered as minor. These effects were shown at the dose of 100 and 250 mg/kg of ammonium glycyrrhizin from 7th to 20th day of pregnancy (soft-tissue abnormalities, mostly renal, and external haemorrhages) and at the dose of 1000 mg/kg of 18β-glycyrrhetinic acid from the 13th day of gestation (significant reduction in lamellar body content of lungs and reduced number alveolar lamellar body and surfactant clusters, but no apparent increase in malformation or foetal death rate).

Another study suggested that 100 mg/kg of liquorice extract repeated for 7 days may also aggravate body weight loss and malformations of foetuses, induced by intrauterine exposure to cyclophosphamide.
