Children under 16 years should not be given this medicine.
Warning: May cause drowsiness. If affected do not drive or operate machinery.
Avoid alcoholic drink.
Asthmatics should consult their doctor before using this product.
Do not use this product for longer than 7 days, unless your doctor agrees.
If symptoms persist consult your doctor.
Do not take anything else containing paracetamol while taking this medicine.
Keep all medicines out of the sight and reach of children.
Talk to a doctor at once if you take too much of this medicine, even if you feel well.
Leaflet or combined label/leaflet:
Talk to a doctor at once if you take too much of this medicine even if you feel well.
This is because too much paracetamol can cause delayed, serious liver damage.
Warning: This product contains 4.8% by volume of ethanol. Each 30ml dose contains
up to 1.16g of alcohol. Harmful to those suffering from liver disease, alcoholism,
epilepsy, brain injury or disease as well as for pregnant women and children. May
modify or increase the effect of other medicines (Alcohol).
Harmful in high doses. Can cause headache, stomach upset and diarrhoea (Glycerol).
May cause diarrhoea (Maltitol/polyols).
Interactions with other Medicaments and other forms of Interaction
Should not be given to patients being treated with monamine oxidase
inhibitors or within 14 days of stopping such treatment. May enhance the
sedative effect of central nervous system depressants including alcohol,
barbiturates, hypnotics, narcotic analgesics, sedatives and tranquillisers. The
effects of anticholinergic drugs such as atropine and tricyclic antidepressants
may also be enhanced. May diminish the antihypertensive effects of
hypotensive drugs and increase the possibility of arrhythmias in digitalised
The speed of absorption of paracetamol may be increased by metoclopramide
or domperidone and absorption reduced by cholestyramine.
The anticoagulant 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.
Pregnancy and Lactation
In view of the possible association of foetal abnormalities with first trimester
exposure to pseudoephedrine and diphenhydramine, use of the product during
pregnancy should be avoided.
Epidemiological studies in human pregnancy have shown no ill effects due to
paracetamol used in the recommend dosage, but patients should follow the
advice of their doctor regarding its use.
Although the safety of this product during lactation has not been established
data on the individual ingredients are available.
Paracetamol is excreted in breast milk but not in a clinically significant
amount. Available published data do not contraindicate breast feeding.
Amounts of pseudoephedrine secreted into breast milk are considered to be too
small to be harmful.
There is no information available as to whether pholcodine is excreted in
breast milk but it is unlikely to be harmful to the infant.
Diphenhydramine is excreted in breast milk but this has not been quantified.
In view of these data, in particular the lack of data on diphenhydramine, the
product should be avoided during lactation.
Effects on ability to drive and use machines
The product may cause drowsiness and patients should be warned not to drive or

Adverse effects of paracetamol are rare but hypersensitivity including skin
rash may occur.
Paracetamol: Very rare cases of serious skin reactions have been reported.
May occasionally cause drowsiness, lassitude, dizziness and muscular
weakness. Other side effects include nausea, vomiting, diarrhoea or
constipation, stomach upset, epigastric pain, headache, blurred vision, tinnitus,
irritability, nightmares, anorexia, difficulty in micturition, dryness of the
mouth, tachycardia, tremors, sputum retention and sweating.
Very rarely there have been reports of blood dyscrasias including
thrombocytopaenia and agranulocytosis, but these were not necessarily
causally related to paracetamol. Hallucinations have been reported rarely, in
association with psuedoephedrine (particularly in children).
Harmful in high doses. Can cause headache, stomach upset and diarrhoea
May cause diarrhoea (Maltitol/Polyols).
Immune system disorders: hypersensitivity reactions, anaphylaxis.
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
Liver damage is possible in adults who have taken 10G 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
Is on long term treatment with carbamazepine, phenobarbitone, phenytoin, primidone,
rifampicin, St John’s Wort or other drugs that induce liver enzymes
Regularly consumes ethanol in excess of recommended amounts OR
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 are 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 odema 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 the 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) but results should not delay initiation of treatment beyond 8
hours after ingestion, as 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 of hospital.
Other symptoms of overdose may include drowsiness, dryness of the mouth,
headache, tachycardia, urinary retention, disorientation, staggering gait,
hallucinations, stupor, hyperreflexia, tremor, excitement, nystagmus, hyperthermia,
convulsions, respiratory depression, hypertension and arrhythmias.
General supportive measures must be available including the administration of a betablocker if supraventricular tachycardia supervenes and the administration of the
specific narcotic antagonist naloxone.
Paracetamol has analgesic and antipyretic actions. Pseudoephedrine is a
sympathomimetic agent with both direct and indirect effects on adrenergic receptors.
Pholcodine is a cough suppressant with little analgesic activity. Diphenydramine is an
antihistamine with anticholinergic properties.
Paracetamol is readily absorbed from the gastrointestinal tract with peak
plasma concentrations occurring about 30 minutes to 2 hours after oral
administration. Paracetamol is distributed into most body tissues. It crosses the
placenta and is present in breast milk. Plasma protein binding is negligible at
usual therapeutic concentrations. Paracetamol is metabolised predominantly
in the liver and excreted in the urine mainly as the glucuronide and sulphate
conjugates with about 10% as glutathione conjugates. Less than 5% is
excreted as unchanged paracetamol. The elimination half life varies from
about 1 to 4 hours.
Pseudoephedrine is absorbed from the gastrointestinal tract. It is resistant to
metabolism and is excreted largely unchanged in the urine. It has a half life of
several hours but elimination is enhanced and half life shortened in acid urine.
Pholcodine is rapidly absorbed after oral administration and maximum plasma
concentrations are attained in about 4-8 hours. The elimination half life ranged
from 32 to 43 hours. The drug has a large volume of distribution and is only
23.5 % protein bound. Pholcodine is metabolised in the liver but undergoes
little conjugation with glucuronide and sulphate.
Diphenhydramine hydrochloride is well absorbed from the gastrointestinal
tract, though high first-pass metabolism appears to affect systemic availability.
Peak plasma concentrations are achieved abut 1 to 4 hours after administration
by mouth. Diphenhydramine is widely distributed throughout the body
including the CNS. It crosses the placenta and has been detected in breast
milk. Diphenhydramine is highly protein bound. Metabolism is extensive and
diphenhydramine is excreted mainly in the urine as metabolites, little being
excreted as unchanged drug. Excretion is almost complete within 24 hours of
