Piriton syrup relieves the symptoms brought on by allergies and one dose can give quick relief with a long lasting effect. It can relieve the itchiness from the chickenpox rash, tosymptoms of hay fever. A powerful drug, it is still gentle enough for people as young as twelve months and, over the decades, it has become a household name for children’s allergies.
Falling into the antihistamine group of drugs, chlorphenamine maleate is the active ingredient and, as a sedative antihistamine, it relieves allergic symptoms. These include:
• food allergies, hay fever, nettle rash (urticaria), insect bites and some medicines
• itching from chickenpox.
Newly developed allergy tablets by Piriton are capable of alleviating symptoms of several different allergic conditions, such as hay fever, insect stings, chickenpox and nettle rash.
Piriton products contain the chlorphenamine as the active ingredient. Chlorphenamine is a sedating antihistamine. This kind of medicine prevents naturally occurring histamine from causing a chain reaction in response to allergens (such as pet fur, or pollen). Chlorphenamine blocks histamine receptors in the body, stopping histamine from beginning this reaction that leads to symptoms appearing.
Chlorphenamine is known as a sedating antihistamine as it affects the brain directly, and causes drowsiness.
Chlorphenamine is particularly effective against chickenpox due to the fact that causes drowsiness on top of its antihistamine effect. Generally itching can get worse at night, particularly in children, so the sedating effect helps reduce this symptom when it’s most problematic.
Drowsiness causing antihistamines such as chlorphenamine are very good at treating allergic reactions like stings, bites, and rashes, as the allergy has already occurred. For treating of longer term allergies like hay fever, a long-acting antihistamine such as cetirizine or loratidine may be more effective.
Piriton syrup works by preventing histamine receptors from creating allergic symptoms. Histamine, a substance which the body produces, reacts to foreign bodies, such as pet fur and pollen (these are classed as allergens) and then creates allergic symptoms, which chlorphenamine blocks.
As a sedating antihistamine, chlorphenamine enters the brain and induces drowsiness and this helps with itching, which is often worse at night. This is particularly the case with children, as itching is more noticeable when they are relaxing than when they are active.
• Drinking alcohol whilst using this medication could exacerbate the side-effects of drowsiness and dizziness.
• Piriton syrup can cause drowsiness, dizziness and blurred vision. Adults should be cautious if driving or operating machinery and children should avoid activities which involve full alertness e.g. climbing trees or riding bikes.
• Piriton syrup can affect the results of an allergy diagnosis done by patch tests and skin pricks, by masking the true results. Stop taking this medication at least 48 hours before having such tests done.
Piriton syrup contains sugar and so people with diabetes should use it with caution. This medication can also cause tooth decay if it is used over a long period of time, so be sure to clean your teeth regularly.
Piriton shouldn’t be taken with the following medicines
• People who have taken a monoamine oxidase inhibitor (MAOI e.g. phenelzine, isocarboxazid, or tranylcypromine) in the last 14 days
• People who are allergic to any of the ingredients in piriton
• As Piriton tablets and Piriton allergy tablets contain lactose, these do not prove suitable to those with rare hereditary problems of galactose intolerance, glucose-galactose malabsorption or Lapp lactase deficiency.
• Piriton syrup also contains sucrose and does not prove suitable to those with rare hereditary problems of fructose intolerance, sucrose-isomaltase insufficiency, or glucose-galactose malabsorption.
If Piriton is taken with any of the following medications, it could increase drowsiness:
• sleeping tablets e.g. zopiclone
• Antipsychotics. e.g. chlorpromazine and haloperidol
• barbiturates e.g. phenobarbital and amobarbital
• benzodiazepines e.g. diazepam and temazepam
• other sedating antihistamines e.g. promethazine and hydroxyzine
• strong opioid painkillers, e.g. codeine, tramadol and morphine
• tricyclic antidepressants e.g. amitriptyline, and nortriptyline.
There could also be an increase in the risk of side-effects e.g. blurred vision, a dry mouth, difficulty passing urine and also constipation, if Piriton is taken with any antimuscarinic medicines which themselves can cause these side-effects. Such medicines include:
• antimuscarinic medicines prescribed for Parkinson's symptoms e.g. orphenadrine, procyclidine and trihexiphenidyl
• antimuscarinic medicines for urinary incontinence e.g. flavoxate, oxybutynin, tolterodine, trospium and propiverine
• some antipsychotics e.g. chlorpromazine and clozapine
• antispasmodics e.g. hyoscine and atropine
• tricyclic antidepressants e.g. imipramine and amitriptyline.
Chlorphenamine can fight the effects of histamine and so, in cases of patients with leukaemia, chlorhenamine should not be considered.
This medication can also fight the effect of betahistine, which is used in the treatment of Ménière's disease).
In the case of epilepsy, chlorphenamine can increase the blood level of phenytoin, an antiepileptic medicine.
