Do not exceed the stated dose.
If symptoms persist consult your doctor.
Keep all medicines out of the sight and reach of children.
Ingredients with specified warnings
This medicine contains Maltitol Liquid and 3.4g sorbitol per 20ml dose. Sorbitol may cause gastrointestinal discomfort and mild laxative effect. Sorbitol is a source of fructose. Patients with rare hereditary problems of fructose intolerance should not take this medicine.
This medicine contains 2880mg of alcohol (ethanol) in each 20ml dose. The amount in 20ml of this medicine is equivalent to 72ml of beer or 29ml of wine. The amount of alcohol in this medicine is not likely to have an effect in adults and adolescents, and its effects in children are not likely to be noticeable. It may have some effects in younger children, for example feeling sleepy. The alcohol in this medicine may alter the effects of other medicines. To be taken into account in those who are breastfeeding, and those who are addicted to alcohol. A dose of 20ml of this medicine administered to an adult weighing 70kg would result in exposure to 41.1mg/kg of ethanol which may cause a rise in blood alcohol concentration (BAC) of about 7.2mg/100ml. Co-administration with medicines containing e.g. propylene glycol or ethanol may lead to accumulation of ethanol and induce adverse effects.
This medicine contains 4300mg propylene glycol per 20ml dose. Not to be taken by those who are breastfeeding or suffer from liver or kidney disease, unless recommended by a doctor.
This medicine contains less than 1 mmol sodium (23 mg) per dose, that is to say essentially 'sodium-free'.
Caution is advised if paracetamol is administered concomitantly with flucloxacillin due to increased risk of high anion gap metabolic acidosis (HAGMA), particularly in patients with severe renal impairment, sepsis, malnutrition and other sources of glutathione deficiency (e.g. chronic alcoholism), as well as those using maximum daily doses of paracetamol. Close monitoring, including measurement of urinary 5-oxoproline, is recommended.
The speed of absorption of paracetamol may be increased by metoclopramide or domperidone; and absorption reduced by colestyramine. The anti-coagulant effect of warfarin and other coumarins may be enhanced by prolonged regular use of paracetamol with increased risk of bleeding; occasional doses have no significant effect. Alcohol may potentiate the hepatotoxicity of paracetamol.
Phenylephrine may reduce the efficacy of beta-blocking drugs and antihypertensive drugs; the product is contraindicated in such circumstances.
With phenylephrine there is a possibility that an increased risk of arrhythmias may occur in patients receiving cardiac glycosides or tri-cyclic anti-depressants. Phenylephrine interacts with monoamine oxidase inhibitors; it should not therefore, be taken by patients receiving monoamine oxidase inhibitors or within 14 days of stopping such medication.
Guaifenesin may interfere with diagnostic measurements of urinary 5-hydroxyindoleacetic acid or vanillylmandelic acid.
Co-administration with medicines containing e.g. propylene glycol or ethanol may lead to accumulation of ethanol and induce adverse effects, in particular in young children with low or immature metabolic capacity.
Caution should be taken when paracetamol is used concomitantly with flucloxacillin as concurrent intake has been associated with high anion gap metabolic acidosis, especially in patients with risks factors (see section 4.4).
A large amount of data on pregnant women indicate neither malformative, nor feto/neonatal toxicity. Epidemiological studies on neurodevelopment in children exposed to paracetamol in utero show inconclusive results, but patients should follow the advice of their doctor regarding its use. Paracetamol is excreted in breast milk but not in a clinically significant amount. Available published data do not contraindicate breast feeding.
Phenylephrine should not be taken during pregnancy as it has been reported to cause foetal hypoxia. Excretion in breast milk is reported to be minimal.
Guaifenesin is considered safe for use in lactating women and at normal doses in pregnant women.
Undesirable effects with paracetamol are rare, however, hypersensitivity including skin rashes may occur. Very rare cases of serious skin reactions have been reported.
There have been a few reports of blood dyscrasias including thrombocytopenia and agranulocytosis after regular or excessive ingestion of paracetamol, and of acute pancreatitis after ingestion of above normal dosage.
Undesirable effects are rare with normal doses of phenylephrine, however it can cause the adverse effects typical of sympathomimetics including: hypertension, palpitations (tachycardia), headache, dizziness, vomiting, diarrhoea and insomnia. Urinary retention has also been reported – this is more likely to occur in men with an enlarged prostate (frequency not known).
Guaifenesin has occasionally been reported to cause gastrointestinal discomfort.
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.
Liver damage is possible in adults who have taken 10 g or more of paracetamol. Ingestion of 5 g or more of paracetamol may lead to liver damage if the patient has risk factors (see below).
If the patient
a) Is on long term treatment with carbamazepine, phenobarbital, phenytoin, primidone, rifampicin, St. John's Wort or other drugs that induce liver enzymes
b) Regularly consumes ethanol in excess of recommended amounts.
c) Is likely to be glutathione deplete e.g. eating disorders, cystic fibrosis, HIV infection, starvation, cachexia.
Symptoms of paracetamol overdosage in the first 24 hours include pallor, nausea, vomiting, anorexia and abdominal pain. Liver damage may become apparent 12 to 48 hours after ingestion. Abnormalities of glucose metabolism and metabolic acidosis may occur. In severe poisoning hepatic failure may progress to encephalopathy, haemorrhage, hypoglycaemia, cerebral oedema, coma and death. Acute renal failure with acute tubular necrosis, strongly suggested by loin pain, haematuria and proteinuria, may develop even in the absence of severe liver damage. Cardiac arrhythmias and pancreatitis have been reported.
Immediate treatment is essential in the management of paracetamol overdose. Despite a lack of significant early symptoms, patients should be referred to hospital urgently for immediate medical attention. Symptoms may be limited to nausea or vomiting and may not reflect the severity of overdose or the risk of organ damage. Management should be in accordance with established treatment guidelines, see BNF overdose section.
Treatment with activated charcoal should be considered if the overdose has been taken within 1 hour. Plasma paracetamol concentration should be measured at 4 hours or later after ingestion (earlier concentrations are unreliable). Treatment with N-acetylcysteine may be used up to 24 hours after ingestion of paracetamol, however, the maximum protective effect is obtained up to 8 hours post-ingestion. The effectiveness of the antidote declines sharply after this time. If required, the patient should be given intravenous N-acetylcysteine, in line with the established dosage schedule. If vomiting is not a problem, oral methionine may be a suitable alternative for remote areas, outside hospital. Management of patients who present with serious hepatic dysfunction beyond 24 hours from ingestion should be discussed with the NPIS or a liver unit.
The principal features of phenylephrine overdosage are a rise in blood pressure and associated reflex bradycardia. A severe hypertensive response can be countered by administration of an alpha-antagonist and any reflex bradycardia by atropine (but preferably only after the pressure has been controlled by alpha-adrenergic blockade).
Very large doses of guaifenesin may cause nausea and vomiting.
Paracetamol has analgesic and antipyretic actions probably due to the inhibition of prostaglandin biosynthesis. It is effective against pain of mild to moderate severity, but is less successful against chronic pain.
Phenylephrine hydrochloride is a sympathomimetic agent with mainly direct effect on adrenergic receptors. It has predominantly alpha-adrenergic activity and is without significant stimulating effects on the central nervous system at usual doses. It may be given orally to relieve nasal congestion.
Guaifenesin is an expectorant which reduces the viscosity of tenacious sputum.
Cetylpyridinium Chloride is a cationic disinfectant with properties and uses similar to other cationic surfactants. These surfactants have bactericidal activity against Gram-positive and, at higher concentration against some Gram-negative organisms. Cetylpyridinium Chloride may be used in a variety of preparations for the local treatment of minor infections.
Paracetamol is readily absorbed from the gastrointestinal tract and peak plasma concentrations usually occur 30 minutes to 2 hours after ingestion. Paracetamol is metabolised in the liver and largely excreted in the urine as sulfate and glucuronide conjugates. Less than 5% is excreted unchanged. The elimination half-life varies from about 1 to 4 hours.
Phenylephrine hydrochloride is irregularly absorbed after oral administration and undergoes first-pass metabolism by monoamine oxidase in the gut and liver, resulting in reduced bioavailability. Peak plasma concentrations are achieved in 1 to 2 hours. It is excreted in the urine mainly as the sulfate conjugate, with less than 20% as unchanged drug.
Guaifenesin is rapidly absorbed from the gastrointestinal tract. It is rapidly metabolised by oxidation to β-(2 methoxy-phenoxy) lactic acid, which is excreted in the urine.
Cetylpyridinium Chloride has only a local effect.
