Triprolidine hydrochloride and pseudoephedrine hydrochloride may cause drowsiness. This product should not be used to sedate a child.

Triprolidine may enhance the sedative effects of central nervous system depressants including alcohol, sedatives and tranquilisers. While taking Rinofed Cold & Allergy Tablets, patients should be advised to avoid alcoholic beverages and consult a healthcare professional prior to taking with central nervous system depressants.

Use with caution in prostatic hypertrophy, urinary retention or susceptibility to angle closure.

Patients with thyroid disease who are receiving thyroid hormones are advised to consult a physician before using this product.

Use with caution in occlusive vascular disease.

If any of the following occur, this product should be stopped.

·    Hallucinations

·    Restlessness

·    Sleep disturbances

·    Severe Skin Reactions: Severe skin reactions such as acute generalized exanthematous pustulosis (AGEP) may occur with pseudoephedrine-containing products. This acute pustular eruption may occur within the first 2 days of treatment, with fever, and numerous, small, mostly non-follicular pustules arising on a widespread oedematous erythema and mainly localized on the skin folds, trunk, and upper extremities. Patients should be carefully monitored. If signs and symptoms such as pyrexia, erythema, or many small pustules are observed, administration of this medicine should be discontinued, and appropriate measures taken if needed.

 

·    Ischaemic colitis: Some cases of ischaemic colitis have been reported with pseudoephedrine. Pseudoephedrine should be discontinued, and medical advice sought if sudden abdominal pain, rectal bleeding or other symptoms of ischaemic colitis develop.

 

·    Ischaemic optic neuropathy: Cases of ischaemic optic neuropathy have been reported with pseudoephedrine. Pseudoephedrine should be discontinued if sudden loss of vision or decreased visual acuity such as scotoma occurs.

There have been rare cases of posterior reversible encephalopathy syndrome (PRES) / reversible cerebral vasoconstriction syndrome (RCVS) reported with sympathomimetic drugs, including pseudoephedrine. Symptoms reported include sudden onset of severe headache, nausea, vomiting, and visual disturbances. Most cases improved or resolved within a few days following appropriate treatment. Pseudoephedrine should be discontinued, and medical advice sought immediately if signs or symptoms of PRES/RCVS develop.

Patients with the following conditions should not use Rinofed Cold & Allergy Tablets unless directed by a physician: acute or chronic asthma, chronic bronchitis or emphysema.

There have been no specific studies of triprolidine hydrochloride and pseudoephedrine hydrochloride in patients with hepatic and/or renal dysfunction. Caution should be exercised in the presence of hepatic or moderate to severe renal impairment.

Rinofed Cold & Allergy contains lactose and sodium

Rinofed Cold & Allergy contains lactose. Each tablet of Rinofed Cold & Allergy 2.5 mg/60 mg Tablets contains 20 mg lactose. If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicinal product.

 

Rinofed Cold & Allergy contains sodium. Each tablet of Rinofed Cold & Allergy 2.5 mg/60 mg Tablets contains 0.35 mg sodium. This medicine contains less than 1 mmol sodium (23 mg) per tablet, that is to say essentially ‘sodium-free’.

MAOIs and/or RIMAs: Pseudoephedrine exerts its vasoconstricting properties by stimulating α-adrenergic receptors and displacing noradrenaline from neuronal storage sites.

 

Since monoamine oxidase inhibitors (MAOIs) impede the metabolism of sympathomimetic amines and increase the store of releasable noradrenaline in adrenergic nerve endings, MAOIs may potentiate the pressor effect of pseudoephedrine. This product should not be given to patients taking monoamine inhibitors or within 14 days of stopping treatment as there is an increased risk of hypertensive crisis (pseudoephedrine) or serotonin syndrome (triprolidine).

Moclobemide: risk of hypertensive crisis

 

Appetite suppressants and amphetamine-like psychostimulants: Concomitant use of this product with sympathomimetic agents, such as decongestants, tricyclic antidepressants, appetite suppressants and amphetamine-like psychostimulants, may cause a rise in blood pressure.

 

Antihypertensives: Because of its pseudoephedrine content, this product may partially reverse the hypotensive action of antihypertensive drugs which interfere with sympathetic activity including bretylium, betanidine, guanethidine, debrisoquine, methyldopa, adrenergic neurone blockers and beta blockers.

 

Cardiac glycosides: increased risk of dysrhythmias

 

Ergot alkaloids (ergotamine & methysergide): increased risk of ergotism

 

Oxytocin: risk of hypertension

 

Anticholinergic drugs: enhances effects of anticholinergic drugs (such as tricyclic antidepressants).

 

Antimuscarinic drugs: may have an additive muscarinic action with other drugs such as atropine and some antidepressants.

 

Anaesthetic agents: Concurrent use with halogenated anaesthetic agents such as chloroform, cyclopropane, halothane, enflurane or isoflurane may provoke or worsen ventricular arrhythmias.

 

CNS depressants: Triprolidine may enhance the sedative effects of CNS depressants including barbiturates, hypnotics, opioid analgesics, anxiolytic sedatives, antipsychotics and alcohol.

This product should not be used during pregnancy or lactation unless the potential benefit of treatment to the mother outweighs the possible risks to the developing foetus or breastfeeding infant.

 Pregnancy

There are no adequate and well-controlled studies for pseudoephedrine or triprolidine, or for the combination of pseudoephedrine and triprolidine, in pregnant women.

 

Breast-feeding

Pseudoephedrine is excreted in breast milk in small amounts, but the effect of this on breast-fed infants is not known. It has been estimated that approximately 0.4 to 0.7% of a single 60mg dose of pseudoephedrine ingested by a nursing mother will be excreted in the breast milk over 24 hours. Data from a study of lactating mothers taking 60 mg pseudoephedrine every 6 hours suggests that from 2.2 to 6.7% of the maximum daily dose (240 mg) may be available to the infant from a breastfeeding mother.

Triprolidine is excreted in breast milk, it has been estimated that approximately 0.06 to 0.2% of a single 2.5 mg dose of triprolidine ingested by a nursing mother will be excreted in the breast-milk over 24 hours.

Rinofed Cold & Allergy may cause drowsiness and impair performance in tests of auditory vigilance. Patients should not drive or operate machinery until they have determined their own response.

Symptoms

The effects of acute toxicity from triprolidine hydrochloride and pseudoephedrine hydrochloride may include drowsiness, lethargy, dizziness, ataxia, weakness, hypotonicity, respiratory depression, dryness of the skin and mucous membranes, tachycardia, hypertension, hyperpyrexia, hyperactivity, irritability, seizures, and difficulty with micturition.

Pseudoephedrine

Overdose may result in hyperglycaemia, hypokalaemia, CNS stimulation, insomnia; irritability, restlessness, anxiety, agitation; confusion, delirium, hallucinations, psychoses, seizures, tremor, intracranial haemorrhage including intracerebral haemorrhage, drowsiness in children, mydriasis, palpitations, tachycardia, reflex bradycardia, supraventricular and ventricular arrhythmias, dysrhythmias, myocardial infarction, hypertension, vomiting, ischaemic bowel infarction, acute renal failure and difficulty in micturition.

Triprolidine

Overdose of an H1 receptor antagonist may result in CNS depression, hyperthermia, anticholinergic syndrome (mydriasis, flushing, fever, dry mouth, urinary retention, decreased bowel sounds), tachycardia, hypotension, hypertension, nausea, vomiting, agitation, confusion, hallucinations, psychosis, seizures, or dysrhythmias. Rhabdomyolysis and renal failure may rarely develop in patients with prolonged agitation, coma, or seizures

Pharmacotherapeutic group: Sympathomimetics, pseudoephedrine combinations

ATC code: R01BA52

 

Triprolidine provides symptomatic relief in conditions believed to depend wholly or partly upon the triggered release of histamine. It is a potent competitive histamine H1-receptor antagonist of the pyrrolidine class with mild central nervous system depressant properties which may cause drowsiness. Pseudoephedrine has direct and indirect sympathomimetic activity and is an effective upper respiratory tract decongestant. Pseudoephedrine is substantially less potent than ephedrine in producing both tachycardia and elevation of systolic blood pressure and considerably less potent in causing stimulation of the central nervous system.

 

After oral administration of a single dose of 2.5mg triprolidine to adults the onset of action, as determined by the ability to antagonise histamine-induced weals and flares in the skin, is within 1 to 2 hours. Peak effects occur at about 3 hours and, although activity declines thereafter, significant inhibition of histamine-induced weals and flares still occurs 8 hours after the dose.

Pseudoephedrine has direct and indirect sympathomimetic activity and is an effective upper respiratory decongestant. Pseudoephedrine is less potent than ephedrine in producing both tachycardia and elevation of systolic blood pressure and is also less potent in causing stimulation of the central nervous system. Pseudoephedrine produces its decongestant effect within 30 minutes, persisting for at least 4 hours.

After the administration of one triprolidine and pseudoephedrine tablet (containing 2.5 mg triprolidine hydrochloride and 60 mg pseudoephedrine hydrochloride) in healthy adult volunteers, the peak plasma concentration (C_max) of triprolidine is approximately 5.5 ng/ml - 6.0 ng/nl, occurring at about 2.0 hours (T_max) after drug administration. The plasma half life of triprolidine is approximately 3.2 hours. The C_max of pseudoephedrine is approximately 180 ng/ml with T_max approximately 2.0 hours after drug administration. The plasma half life of pseudoephedrine is approximately 5.5 hours (urine pH maintained between 5.0-7.0). The plasma half life of pseudoephedrine is markedly decreased by acidification of urine and increased by alkalinisation.

There is insufficient information available to determine whether Triprolidine pseudoephedrine have mutagenic or carcinogenic potential.

 

Systematic administration of pseudoephedrine in rats, up to 7 times the human daily dosage in females and 35 times the human daily dosage in males, did not impair fertility nor alter foetal morphological development and survival.

 

No studies have been conducted in animal to determine if Triprolidine has the potential to impair fertility.

 

Systemic administration of Triprolidine in rats and rabbits up to 75 times the human dose did not produce teratogenic effects.

 

Systemic administration of pseudoephedrine, up to 50 times the human daily dosage in rats and up to 35 times the human daily dosage in rabbits, did not produce teratogenic effects.
