For nasal congestion, colds and catarrh: Rub onto the chest and throat as required.
Do not apply to the nostrils of infants.
For the relief of muscular pains and stiffness: Rub into the affected parts as required.
Do not use for infants under 3 months.
4.3 Contraindications
Known hypersensitivity to salicylates or to any of the other ingredients in the preparation. If irritation develops, use of the product should be discontinued.
4.4 Special warnings and precautions for use
Use this medicine only on your skin
To be applied to the unbroken skin only, avoiding sensitive skin areas.
Not to be applied to the nostrils of infants.
Do not use for infants under 3 months.
Instruct patients not to smoke or go near naked flames – risk of severe burns.
Fabric (clothing, bedding, dressings etc) that has been in contact with this product burns more easily and is a serious fire hazard. Washing clothing and bedding may reduce product build-up but not totally remove it.
4.5 Interaction with other medicinal products and other forms of interaction
There have been reports that topical salicylates may potentiate the anticoagulant effects of warfarin. Menthol has also been reported to interact with warfarin (when taken orally), decreasing its effectiveness.
4.6 Fertility, pregnancy and lactation
There is no, or inadequate evidence of safety in human pregnancy or lactation. As a precautionary measure, this medicine should only be used during pregnancy and lactation when there is no safer alternative.
4.7. Effects on Ability to Drive and Use Machines
Not applicable.
4.8 Undesirable effects
If a skin rash occurs, stop using the product.
Known side effects of menthol – contact dermatitis or eczema, hypersensitivity reactions characterised by urticaria, flushing and headache.
General disorders and administration site conditions Not known: Burns at application site.
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.
4.9 Overdose
When used externally as directed, overdose is unlikely. However, symptoms of systemic salicylate poisoning have been reported after the application of salicylates to large areas of skin or for prolonged periods. Salicylism may also occur in the unlikely event of large quantities being ingested.
Salicylate poisoning
Common features include vomiting, dehydration, tinnitus, vertigo, deafness, sweating, warm extremities with bounding pulses, increased respiratory rate and hyperventilation. Some degree of acid-base disturbance is present in most cases.
A mixed respiratory alkalosis and metabolic acidosis with normal or high arterial pH (normal or reduced hydrogen ion concentration) is usual in adults and children over the age of four years. In children aged four years or less, a dominant metabolic acidosis with low arterial pH (raised hydrogen ion concentration) is common. Acidosis may increase salicylate transfer across the blood brain barrier.
Uncommon features include haematemesis, hyperpyrexia, hypoglycaemia, hypokalaemia, thrombocytopenia, increased INR/PTR, intravascular coagulation, renal failure and non-cardiac pulmonary oedema.
Central nervous system features including confusion, disorientation, coma and convulsions are less common in adults than in children.
Management
Activated charcoal may be administered if significant quantities have been ingested within an hour of presentation. The plasma salicylate concentration should be measured, although the severity of poisoning cannot be determined from this alone and the clinical and biochemical features must be taken into account. Elimination is increased by urinary alkalinisation, which is achieved by the administration of 1.26% sodium bicarbonate. The urine pH should be monitored. Correct metabolic acidosis with intravenous 8.4% sodium bicarbonate (first check serum potassium). Forced diuresis should not be used since it does not enhance salicylate excretion and may cause pulmonary oedema.
Haemodialysis is the treatment of choice for severe poisoning and should be considered in patients with plasma salicylate concentrations >700mg/L (5.1mmol/L), or lower concentrations associated with severe clinical or metabolic features. Patients under 10 years or over 70 have increased risk of salicylate toxicity and may require dialysis at an earlier stage.
Camphor and Menthol
Ingestion of the product or excessive use may also lead to camphor poisoning, the symptoms of which include nausea, vomiting, epigastric pain, headache, dizziness, oropharyngeal burning, delirium, muscle twitching, epileptiform convulsions, CNS depression and coma. Breathing is difficult and the breath has a characteristic odour; anuria may occur. Death from respiratory failure or status epilepticus may occur;
fatalities in children have been recorded from 1g. Supportive care, including anticonvulsant therapy, is the mainstay of treatment of camphor intoxication. Gastric lavage may be considered if the patient presents within 1 hour of ingestion; any convulsions must be controlled first. Activated charcoal may be given orally.
Ingestion of significant quantities of menthol is reported to cause symptoms similar to those seen after ingestion of camphor, including severe abdominal pain, nausea, vomiting, vertigo, ataxia, drowsiness, and coma; they may be managed similarly.
5. PHARMACOLOGICAL PROPERTIES
5.1 Pharmacodynamic Properties

Terpineol: Essential oil, antiseptic.
Methyl Salicylate: Actions typical of salicylates including analgesic and antiinflammatory activity.
Camphor: Rubefacient, mild analgesic.
Menthol: Dilates superficial vessels, relieves minor local irritation.
