Interaction of Avil 75 ml
MAO-inhibitors may prolong and intensify the anticholinergic effect of pheniramine (see Contraindications).
Adverse CNS effects of pheniramine may be enhanced when it is taken with alcohol or other CNS depressants (eg. hypnotics, sedatives, tranquilizers).
Atropine and related drugs may enhance the anticholinergic activity of pheniramine.
Contraindications
Patients with hypersensitivity to pheniramine or any other ingredient (eg. Methyl hydroxybenzoate or propyl hydroxybenzoate in the syrup).
Patients with symptomatic prostatic hypertrophy.
Patients receiving MAO-inhibitor therapy.
Newborn and premature infants.
Side Effects of Avil 75 ml
The most common adverse reaction is sedation, which often disappears after a few days if tolerance is acquired. Hypersensitivity reactions have been reported.
Central Nervous System: Lassitude, dizziness, tinnitus, inability to concentrate, incoordination, irritability, insomnia and tremors. Agitation and convulsions, especially in children and restlessness, disorientation and hallucinations in adults, are common symptoms following overdose.
Gastrointestinal: Nausea, vomiting, diarrhoea, colic, epigastric pain, anorexia, dryness of mouth and constipation.
Genitourinary: Urinary retention.
Cardiovascular: Palpitations, headache.
Ocular: Blurred vision, increased intraocular pressure.
Musculoskeletal: Muscular weakness.
Haematological: Rare cases of blood dyscrasias including agranulocytosis and haemolytic anaemia have been reported.
Pregnancy & Lactation
Pregnancy Category C. Either studies in animals have revealed adverse effects on the foetus (teratogenic or embryocidal or other) and there are no controlled studies in women or studies in women and animals are not available. Drugs should be given only if the potential benefit justifies the potential risk to the foetus.
Precautions & Warnings
Avil 75 ml may cause drowsiness. Both the dosage and the time of administration should be carefully considered in patients whose activities (e.g. driving a car or operating machinery) demand special concentration.
Patients should be cautioned against the simultaneous ingestion of alcohol and other central nervous system depressants. Avil 75 ml may possibly be hallucinogenic in toxic doses. Due to the possible CNS stimulating effects of antihistamines, pheniramine has the potential for abuse.
Due to the anticholinergic effect of pheniramine, caution and close monitoring are required if it is used in patients with conditions such as prostatic hypertrophy, narrow angle glaucoma, asthma or severe cardiovascular disease.
The anti-emetic effect of pheniramine may mask the signs of other conditions. Products containing pheniramine should not be taken on an empty stomach.
Overdose Effects of Avil 75 ml
Symptoms: Antihistamine drugs in toxic doses produce a complex of CNS excitatory and depressant effects. Accidental ingestion in small children has resulted in convulsions and sometimes death.Management: As there is no specific antidote, treatment should be symptomatic and supportive. Induction of vomiting should only be used immediately after ingestion as the sedative action of any absorbed antihistamine can lead to life-threatening pulmonary aspiration during emesis. Gastric lavage with a cuffed endotracheal tube in situ may be useful for some time after ingestion of antihistamines as their anticholinergic action slows down gastric emptying. Stimulants should not be used as they may precipitate convulsions. Diazepam or short-acting barbiturates may be used to control convulsions. Vasopressors may be used to treat hypotension. Mechanical support of respiration may be required if respiration is seriously depressed. Continuous ECG monitoring is recommended if cardiac toxicity develops, which can be treated with centrally-acting anticholinesterases such as physostigmine.
Storage Conditions
Store in a cool and dry place, protected from light. Do not use later than the date of expiry. Keep all medicines out of the reach of children. To be dispensed only on the prescription of a registered physician.
Drug Classes
Sedating Anti-histamine
Mode Of Action
Pheniramine competes with histamine for the histamine H1 receptor, acting as an inverse agonist once bound. The reduction in H1 receptor activity is responsible for reduced itching as well as reduced vasodilation and capillary leakage leading to less redness and edema. This can be seen in the suppression of the histamine-induced wheal (swelling) and flare (vasodilation) response. Inverse agonism of the H1 receptor in the CNS is also responsible for the sedation produced by first-generation antihistamines like pheniramine. The binding of pheniramine to H4 receptors, and subsequent inverse agonism, may also contribute to reduced itching by antagonizing inflammation.
Pregnancy
pregnancy Category A. Use only if strictly indicated. Use only if strictly indicated.
