This medicine contains sodium methyl, ethyl and propyl parahydroxybenzoate which may cause allergic reactions (possibly delayed).
This medicine contains less than 1mmol sodium (23mg) per 5ml dose, that is to say essentially 'sodium-free'.
Toxicity of squill glycosides may be increased when given in combination with thiazides or loop diuretics, as these may cause hypokalaemia and hypomagnesaemia, which may lead to cardiac arrhythmias.
When used with carbenoxolone it may produce sodium and water retention and hypokalaemia. and may give rise to greater toxicity of squill.
There are no adverse reports when used in recommended doses.
However, as with all medicines care should be taken when using this product in pregnancy and medical advice sought if necessary.
Hypersensitivity reactions and gastrointestinal reactions have been reported with this product. Hypersensitivity reactions may include generalised urticaria, flushing and contact dermatitis.
Liquorice may cause sodium and water retention, and hypokalaemia.
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.
Ingestion of large doses of the active ingredients has been reported to cause the following effects: Gastrointestinal disturbances such as abdominal pain, nausea, vomiting and diarrhoea would be expected to occur with the menthol and squill.
Common symptoms of digoxin overdosage include headache, facial pain, fatigue, weakness, dizziness, drowsiness, disorientation, mental confusion, bad dreams and more rarely delirium, acute psychoses, and hallucinations. Convulsions have been reported. Visual disturbances including blurred vision may occur. Colour vision may be affected with objects appearing yellow or less frequently green, red, brown, blue or white.
Adverse effects on the heart may result from the cardiac glycosides in squill. Toxic doses may cause or aggravate heart failure. Supraventricular or ventricular arrhythmias and defects of conduction are common and may be an early indication of excessive dosage.
In addition CNS effects such as vertigo, ataxia and drowsiness have been reported after ingestion of large quantities of menthol; reported adverse effects following excessive ingestion of liquorice include hypertension, congestive heart failure, cardiac arrest, headache, muscle weakness, myopathy, myoglobinuria, paralysis, hyperprolactinaemia and amenorrhoea.
In the unlikely event of overdosage with this preparation, gastric lavage and / or symptomatic treatment together with supportive measures should be employed. Treatment of acute digoxin poisoning consists of emptying the stomach by emesis or lavage. Activated charcoal may be given. Cardiac toxicity should be treated under ECG control and serum electrolytes should be monitored. Anti-arrhythmic treatment may be necessary and should be determined by the specific arrhythmia present. Atropine may be given intravenously to control bradycardia and in patients with heart block; cardiac pacing may be necessary if atropine is not effective. Colestyramine or colestipol may be of use in increasing the elimination of cardiac glycosides.
R05C – Cough and cold preparations, expectorants, excl. combinations with cough suppressants
Menthol dilates the blood vessels causing a sensation of coldness followed by analgesic effect. It is used to relieve the symptoms of bronchitis, sinusitis and similar conditions.
Squill has an irritant effect on the gastric mucosa, it has a reflex expectorant action.
Liquorice is a demulcent and mild expectorant.
After absorption menthol is excreted in the bile and urine as a glucuronide.
Squill glycosides are poorly absorbed from the gastro-intestinal tract, they are of short acting duration and are not cumulative, they are excreted in the urine and faeces.
No information is available on the pharmacokinetics of liquorice.
