Interaction with other medicinal products and other forms of interaction
The rate of absorption of paracetamol may be increased by metoclopramide or domperidone
and absorption may be 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
Monoamine oxidase inhibitors (including moclobemide): hypertensive interactions occur
between sympathomimetic amines such as phenylephrine and monoamine oxidase inhibitors
(see section 4.3).
Sympathomimetic amines: concomitant use of phenylephrine with other sympathomimetic
amines can increase the risk of cardiovascular side effects.
Beta-blockers and other antihypertensives (including debrisoquine, guanethidine, reserpine,
methyldopa): phenylephrine may reduce the efficacy of beta-blockers and antihypertensives.
The risk of hypertension and other cardiovascular side effects may be increased (see section
Tricyclic antidepressants (e.g. amitriptyline): may increase the risk of cardiovascular side
effects with phenylephrine (see section 4.3).
Digoxin and cardiac glycosides: concomitant use of phenylephrine may increase the risk of
irregular heartbeat or heart attack.
Guaifenesin may interfere with diagnostic measurements of urinary 5-hydroxyindoleactic acid
or vanillylmandelic acid. If urine is collected within 24 hours of a dose of the medicinal
product, a metabolite of guaifenesin may cause a colour interference with laboratory
determinations of urinary 5-hydroxyindoleacetic acid (5-HIAA) and vanillylmandelic acid
Fertility, Pregnancy and Lactation
The product should not be used during pregnancy unless recommended by a healthcare
The safety of this medicine during pregnancy and lactation has not been established but in
view of a possible association of foetal abnormalities with first trimester exposure to
phenylephrine, the use of the product during pregnancy should be avoided. In addition,
because phenylephrine may reduce placental perfusion, the product should not be used in
patients with a history of preeclampsia.
Epidemiological studies in human pregnancy have shown no ill effects due to paracetamol
used in the recommended dosage.
There are limited data on the use of guaifenesin in pregnant women. Guaifenesin has been
linked with an increased risk of neural tube defects in a small number of women with febrile
illness in the first trimester of pregnancy.
The product should be avoided during lactation unless recommended by a healthcare
professional. There are limited data on the use of phenylephrine in lactation.
Paracetamol is excreted in breast milk, but not in a clinically significant amount. Available
published data do not contraindicate breast feeding.
There is no information on the use of guaifenesin in lactation.
There are no available data regarding the effects of the active ingredients on fertility.
Effects on ability to drive and use machines
Lemsip Max All in One Lemon has no or negligible influence on ability to
drive or use machinery.

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.
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, phenobarbitone, 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 depleted, e.g. eating disorders, cystic fibrosis, HIV infection,
Symptoms of paracetamol overdose 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
oedema, 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.
Features of severe overdose of phenylephrine include haemodynamic changes and
cardiovascular collapse with respiratory depression. Treatment includes symptomatic and
supportive measures. Hypertensive effects may be treated with an i.v. alpha-receptor-blocking
Phenylephrine overdose is likely to result in: nervousness, headache, dizziness, insomnia,
increased blood pressure, nausea, vomiting, mydriasis, acute angle closure glaucoma (most
likely to occur in those with closed angle glaucoma), tachycardia, palpitations, allergic
reactions (e.g. rash, urticaria, allergic dermatitis), dysuria, urinary retention (most likely to
occur in those with bladder outlet obstruction, such as prostatic hypertrophy).
Additional symptoms may include, hypertension, and possibly reflex bradycardia. In severe
cases confusion, seizures and arrhythmias may occur. However the amount required to
produce serious phenylephrine toxicity would be greater than that required to cause
paracetamol-related liver toxicity.
Treatment should be as clinically appropriate. Severe hypertension may need to be treated
with alpha blocking medicinal products such as phentolamine.
Very large doses may cause nausea and vomiting. The active substance is, however, rapidly
metabolised and excreted in the urine. Patients should be kept under observation and treated
Pharmacotherapeutic group: Analgesics, Anilides,
ATC Code: N02B E51. Paracetamol, combinations excl. psycholeptics
Paracetamol: Paracetamol has both analgesic and antipyretic activity, which is believed to be
mediated principally through its inhibition of prostaglandin synthesis within the central
Phenylephrine hydrochloride: Phenylephrine is sympathomimetic post-synaptic α1–adrenergic
receptor agonist with low cardioselective beta receptor affinity and minimal central nervous
stimulant activity. It is a recognised decongestant and acts by vasoconstriction to reduce
oedema and nasal swelling.
Guaifenesin: Guaifenesin is an expectorant which reduces the viscosity of tenacious sputum.
The active ingredients are not known to cause sedation.
Paracetamol: Paracetamol is absorbed rapidly and completely from the small intestine,
producing peak plasma levels after 15-20 minutes following oral dosing. The systemic
availability is subject to first-pass metabolism and varies with dose between 70% and 90%.
The drug is rapidly and widely distributed throughout the body and is eliminated from plasma
with a T½ of approximately 2 hours. The major metabolites are glucuronide and sulphate
conjugates (>80%) which are excreted in urine.
Phenylephrine hydrochloride: Phenylephrine is absorbed from the gastrointestinal tract, but
has reduced bioavailability by the oral route due to first-pass metabolism. It retains activity as
a nasal decongestant when given orally, the drug distributing through the systemic circulation
to the vascular bed of the nasal mucosa. When taken by mouth as a nasal decongestant
phenylephrine is usually given at intervals of 4-6 hours.
Guaifenesin: Guaifenesin is absorbed from the gastrointestinal tract. It is rapidly metabolised
by oxidation to ί-(2 methoxy-phenoxy) lactic acid; which is excreted in the urine. Within 3
hours, approximately 40% of a single dose is excreted in the urine as this metabolite. The halflife in plasma is approximately 1 hour. Guaifenesin may increase the rate of absorption of
