• Motion sickness.
• Nausea and vomiting caused by narcotic analgesics and by general anaesthetics in the post-operative period.
• Vomiting associated with radiotherapy, especially for breast cancer since cyclizine does not elevate prolactin levels.
Cyclizine Tablets may be of value in relieving vomiting and attacks of vertigo associated with Meniere's disease and other forms of vestibular disturbance.
4.2. Posology and method of administration
Posology
To prevent motion sickness Cyclizine Tablets should be taken about one to two hours before departure.
Elderly
There have been no specific studies of Cyclizine Tablets in the elderly. Experience has indicated that normal adult dosage is appropriate.
Paediatric population
Children less than 6 years of age:
Cyclizine Tablets are not recommended for children less than 6 years of age.
Children 6 to 12 years of age:
25 mg orally, which may be repeated up to three times a day.

Method of administration:
Oral.
4.3. Contraindications
Hypersensitivity to the active substance or to any of the excipients listed in section 6.1.
Cyclizine is contraindicated in the presence of acute alcohol intoxication. The anti-emetic properties of cyclizine may increase the toxicity of alcohol.
4.4. Special warnings and precautions for use
As with other anticholinergic agents, Cyclizine Tablets may precipitate incipient glaucoma and it should be used with caution and appropriate monitoring in patients with glaucoma, urinary retention, obstructive disease of the gastrointestinal tract, hepatic disease, phaeochromocytoma, hypertension, epilepsy and in males with possible prostatic hypertrophy.
Cyclizine should be used with caution in patients with severe heart failure or acute myocardial infarction. In such patients, cyclizine may cause a fall in cardiac output associated with increases in heart rate, mean arterial pressure and pulmonary wedge pressure.
Cyclizine should be avoided in porphyria.
There have been reports of abuse of cyclizine, either oral or intravenous, for its euphoric or hallucinatory effects. The concomitant misuse of Cyclizine Tablets with large amounts of alcohol is particularly dangerous, since the antiemetic effect of cyclizine may increase the toxicity of alcohol (see also sections 4.3 and 4.5).
Excipients
Patients with rare hereditary problems of galactose intolerance, the total lactase deficiency or glucose-galactose malabsorption should not take this medicine.
This medicine contains less than 1 mmol sodium (23 mg) per tablet, that is to say essentially 'sodium-free'.
4.5. Interaction with other medicinal products and other forms of interaction
Cyclizine Tablets may have additive effects with alcohol and other central nervous system depressants e.g. hypnotics, tranquillisers, anaesthetics, antipsychotics, barbiturates.
Cyclizine Tablets enhances the soporific effect of pethidine.
Cyclizine Tablets may counteract the haemodynamic benefits of opioid analgesics.
Because of its anticholinergic activity cyclizine may enhance the side-effects of other anticholinergic drugs, and have an additive antimuscarinic action with other antimuscarinic drugs, such as atropine and some antidepressants (both tricyclics and MAOIs).
Cyclizine Tablets may mask the warning signs of damage caused by ototoxic drugs such as aminoglycoside antibacterials.
4.6. Fertility, pregnancy and lactation
Pregnancy
In the absence of any definitive human data, the use of Cyclizine Tablets in pregnancy is not advised.
Breast-feeding
Cyclizine is excreted in human milk; however, the amount has not been quantified.
Fertility
In a study involving prolonged administration of cyclizine to male and female rats, there was no evidence of impaired fertility after continuous treatment for 90-100 days at dose levels of approximately 15 and 25 mg/kg/day. There is no experience of the effect of Cyclizine Tablets on human fertility.
4.7. Effects on ability to drive and use machines
Studies designed to detect drowsiness did not reveal sedation in healthy adults who took a single oral therapeutic dose (50 mg) of cyclizine.
Patients should not drive or operate machinery until they have determined their own response.
Although there are no data available, patients should be cautioned that Cyclizine Tablets may have additive effects with alcohol and other central nervous system depressants, e.g. hypnotics and tranquillisers.

4.9. Overdose
Symptoms:
Symptoms of acute toxicity from cyclizine arise from peripheral anticholinergic effects and effects on the central nervous system.
Peripheral anticholinergic symptoms include dry mouth, nose and throat, blurred vision, tachycardia and urinary retention. Central nervous system effects include drowsiness, dizziness, incoordination, ataxia, weakness, hyperexcitability, disorientation, impaired judgement, hallucinations, hyperkinesia, extrapyramidal motor disturbances, convulsions, hyperpyrexia and respiratory depression.
An oral dose of 5 mg/kg is likely to be associated with at least one of the clinical symptoms stated above. Younger children are more susceptible to convulsions. The incidence of convulsions, in children less than 5 years, is about 60% when the oral dose ingested exceeds 40 mg/kg.
Management:
In the management of acute overdosage with Cyclizine Tablets, gastric lavage and supportive measures for respiration and circulation should be performed if necessary. Convulsions should be controlled in the usual way with parenteral anticonvulsant therapy.
