4.3 Contraindications

Phenergan should not be used in patients in pre-coma states, in a coma or suffering from CNS depression of any cause.

It must not be given to neonates, or premature infants.

Phenergan should not be given to patients with a known hypersensitivity to promethazine or to any of the excipients.

Phenergan should be avoided in patients with blood dycrasias and in patients taking monoamine oxidase inhibitors up to 14 days previously.

Promethazine is contraindicated for use in children less than two years of age because of the potential for fatal respiratory depression.

4.4 Special warnings and precautions for use

Caution should be used in patients with pre-existing coronary insufficiency. Adjustment of dosage may be necessary to avoid postural hypotension, especially in the elderly.

Since the drug is metabolized in the liver, promethazine should be used cautiously in patients with hepatic impairment.

Prolonged treatment with this product may result in jaundice or blood dyscrasia necessitating regular monitoring of liver function and haemopoietic state.

Particular attention should also be paid to potential for inducing eye changes and myocardial conduction defects, especially if other concurrently administered drugs also have potential effects on these systems.

Body temperature may fall during treatment with this product and special care should be exercised in this regard in the elderly.

Promoethazine should only be used cautiously in epileptic patients, since central nervous stimulation may sometimes occur. Caution should also be exercised in patients with narrow angle glaucoma, renal insufficiency, bladder-neck or pyloro-duodenal obstruction.

Promethazine may thicken or dry lung secretions and impair expectoration. It should be used with caution in patients with asthma, bronchitis or bronchiectasis.

Promethazine may delay the elderly diagnosis of intestinal obstruction or increased intracanial pressure through the suppression of vomiting.

Promethazine may mask the warning signs of ototoxicity caused by ototoxic drugs e.g. salicylates.

There have been case reports of drug abuse with promethiazine. The risk of abuse is greater in patients with a history of drug abuse.

Neuroleptic malignant syndrome: As with neuroleptics, Neuroleptic Malignant Syndrome (NMS) characterized by hyperthermia, extrapyramidal disorders, muscle rigidity, altered mental status, autonomic nervous instability and elevated CPK, may occur. As this syndrome is potentially fatal, promethiazine must be discontinued immediately and intensive clinical monitoring and symptomatic treatment should be initiated.

Promethiazine must not be used in children below two years of age due to the potential for fatal respiratory depression.

Phenothiazines should be used with caution in patients with cardiac disease or cardiac arrhythmias.

The use of promethazine should be avoided in children and in adolescents with signs and symptoms suggestive of Reye's Syndrome.

Phenergan should not be used for longer than 7 days without seeking medical advice.

4.5 Interaction with other medicinal products and other forms of interaction

The product may potentiate the effects of alcohol and other central nervous system depressants.

Attention is drawn to the fact that many psychotropic and anti-histamine drugs are of the phenothiazine group, and a combination of both may lead to toxicity. Potentiation of action may also occur with monoamine oxidase inhibitors and analgesics. Use of promethazine should be avoided in patients taking monoamine oxidase inhibitors up to 14 days previously.

Antihypertensive therapy used concurrently may need adjustment of dosage to avoid hypotension, particularly in the elderly.

Promethazine may interfere with immunological urine pregnancy tests.

Phenergan should be discontinued at least 72 hours before commencing skin tests using allergen extracts, as the cutaneous histamine response may be inhibited.

Promethazine may lower the convulsion threshold. Dosage adjustment of anticonvulsant medication may be necessary.

Concurrent use of promethazine with other hepatotoxic medications may increase the potential for hepatotoxicity.

Concurrent use with other photosensitizing medications, e.g. tetracyclines, may cause additive photosensitizing effects.

4.6 Fertility, pregnancy and lactation

Phenergan should not be used in pregnancy unless the physician considers it essential. The use of Phenergan is not recommended in the 2 weeks prior to delivery in view of the risk of irritability and excitement in the neonate.

Available evidence suggests that the amount excreted in milk is insignificant. However, there are risks of neonatal irritability and excitement.

4.7 Effects on ability to drive and use machines

Because the duration of action may be up to 12 hours, patients should be advised that if they feel drowsy they should not drive or operate heavy machinery.

4.8 Undesirable effects

The following side effects have been observed: drowsiness or dizziness, restlessness, headaches, nightmares, tiredness or disorientation. Anti-cholinergic side effects such as blurred vision, dry mouth and urinary retention occur occasionally. Children may display paradoxical hyperexcitability. Anaphylaxis, jaundice and blood dyscrasias including haemolytic anaemia rarely occur.

Use of this product at high (relative or absolute) doses may induce extra pyramidal side effects e.g. dyskinesia, akathisia, dystonia, especially in the presence of pre-existing brain damage. These are likely to be particularly severe in children. Children may also display parodoxical hyperexcitability.

Prolonged administration of this product may result in persistent or tardive dyskinesias particularly in the elderly. Other side effects in the elderly include anorexia, gastric irritation, palpitations, hypotension, arrhythmias, extrapyramidal effects, muscle spasms, and tic-like movements of the head and face.

The effect of phenothiazines on the heart are dose related. ECG changes, with prolongation of QT interval and T-wave changes have been reported commonly in patients treated with moderate or high dose; they are reversible on reducing the dose. In a very small percentage of cases they have been reported to precede serious arrhythmias, including ventricular tachycardia and fibrillation, which have also occurred after overdosage. Sudden, unexpected and unexplained deaths have been reported in patients receiving phenothiazines.

Frequency unknown: Neuroleptic Malignant Syndrome.

Very rare cases of allergic reactions, including urticaria, rash, pruritus and anaphalyxis have been reported. Photosensitive skin reactions have been reported. Strong sunlight should be avoided during treatment.

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 HPRA Pharmacovigilance, Earlsfort Terrace, IRL - Dublin 2; Tel: +353 1 6764971; Fax: +353 1 6762517. Website: www.hpra.ie; E-mail: medsafety@hpra.ie.

4.9 Overdose

Symptoms of severe overdosage are variable. They are characterised in children by various combinations of excitation, ataxia, incoordination, athetosis and hallucinations, while adults may become drowsy and lapse into coma. Convulsions may occur in both adults and children. Coma may precede their occurrence. Tachycardia may develop. Cardiorespiratory depression is not uncommon. If the patient is seen soon enough after ingestion, it should be possible to induce vomiting with ipecacuanha despite the antiemetic effect of promethazine; alternatively, gastric lavage may be used.

Treatment is otherwise supportive with attention to maintenance of adequate respiratory and circulatory status. Convulsions should be treated with diazepam or other suitable anticonvulsant.
