WHAT IS THE DIFFERENCE BETWEEN ALLERGEX NON-DROWSY SYRUP AND TABLETS?

Both Allergex Non-Drowsy syrup and tablets are indicated for the relief of symptoms associated with allergic rhinitis, rhinorrhoea (runny nose), itching of the nose and throat, chronic idiopathic urticaria (hives) and other allergic dermatoses (allergic skin reactions). ¹ 1

The differences lie in the format, composition, dosage and usage by children and adults. Join us as we place these differences under a microscope.

Dosage

Allergex Non-Drowsy Syrup can be prescribed to both adults and children of two years and over, but the tablets can only be used by adults. The dosage indicated for children and adults also vary. ¹,² 1

See the dosage summary below:

  • Children from two to five years old: 5 ml (1 medicine measure) once daily¹
  • Children from six to twelve years old: 10 ml (2 medicine measures) once daily¹
  • Adults and children of twelve years and older: 10 ml (2 medicine measures)
  • One Allergex Non-Drowsy tablet daily 2 1

Composition and classification

Both Allergex Non-Drowsy syrup and tablets are pharmacologically classified as antihistaminics that contain Loratadine, a long lasting antihistamine.¹,² 2, 3

The difference lies in the composition. Each Allergex Non-Drowsy tablet contains 10 mgs of Loratadine which is micronized and 75 mgs of lactose monohydrate.² 2

Each 5 ml of Allergex Non-Drowsy syrup on the other hand, only contains 5 mgs of micronised Loratadine, as well as 0, 1% m/v sodium benzoate as a preservative, as well as 1,000 mgs of sucrose. ¹ 3

Format

Naturally the format of Allergex Non-Drowsy tablets and syrup are also different. Allergex Non-Drowsy tablets are available in easy-to-carry-around packs of ten or thirty tablets and the syrup is available in 150 ml bottles. ¹,² 1

Availability

Both Allergex Non-Drowsy tablets and syrup are available over-the-counter at most leading pharmacies. 1

As there are a multitude of factors that can influence its usage and efficacy, such as chronic medicine you may be using or other medical conditions you may have, it is always best to consult with your pharmacist or GP first.

SCHEDULING STATUS:         S2

PROPRIETARY NAME:           ALLERGEX® NON-DROWSY TABLETS

(AND DOSAGE FORM)           (TABLET)

COMPOSITION:

Each tablet contains:

Loratadine (micronised)          10 mg

Contains sugar:

Lactose monohydrate 75 mg

PHARMACOLOGICAL CLASSIFICATION:

A: 5.7.1 Antihistaminics

PHARMACOLOGICAL ACTION:

Loratadine is a long acting piperidine antihistamine. 2

It is a selective H1 receptor antagonist which is a reversible, competitive inhibitor of histamine at H1 receptor sites.

Loratadine is a second generation H1 antagonist.

It does not readily cross the blood brain barrier.

 Pharmacokinetics:

Peak plasma levels are reached within 1,5 hours and the clinical effect is achieved within 2 hours.

Excretion occurs equally via the faeces and the urine.

INDICATIONS:

The relief of symptoms associated with seasonal allergic rhinitis and chronic urticaria.

CONTRAINDICATIONS:

ALLERGEX NON DROWSY TABLETS is contraindicated in individuals who have shown hypersensitivity to any of its ingredients.

Safety in pregnancy and lactation has not been established.

The safe use of ALLERGEX NON DROWSY TABLETS in the elderly has not been established.

DOSAGE AND DIRECTIONS FOR USE:

One tablet to be taken once daily.

SIDE EFFECTS AND SPECIAL PRECAUTIONS:

Most commonly reported side effects include fatigue, headache, somnolence and dry mouth.

Gastrointestinal side effects including nausea, vomiting, diarrhoea, gastritis or epigastric pain may occur.

Allergic symptoms like rashes and hypersensitivity reactions may occur.

Abnormal hepatic function, alopecia and anaphylaxis have also been reported.

Precautions:

ALLERGEX NON-DROWSY TABLETS lack significant sedative properties. However, patients should be advised that a small number of individuals may experience sedation. Therefore, the effect of the medicine on a particular patient should be ascertained before they drive or operate machinery. This effect can be compounded by the simultaneous intake of alcohol or other central nervous system depressants.

A lower dose should be administered to patients with hepatic impairment as they may have decreased clearance of loratadine; i.e. an initial dose of 5 mg once daily or 10 mg on alternate days.

Medicine/laboratory test interactions:

The use of ALLERGEX NON DROWSY TABLETS should be stopped several days before skin testing as antihistamines may suppress the positive skin response to allergen extracts.

Medicines known to inhibit the hepatic metabolism of loratadine include cimetidine, erythromycin, ketoconazole, quinidine, fluconazole and fluoxetine. These medicines should therefore not be administered concomitantly with loratadine as they may raise the plasma concentrations of loratadine.

However, no clinically significant consequences have been observed when these medicines are administered concomitantly.

KNOWN SYMPTOMS OF OVERDOSAGE AND PARTICULARS OF ITS TREATMENT:

See “SIDE EFFECTS AND SPECIAL PRECAUTIONS”.

Cardiac effects such as tachycardia have been reported.

Headache and somnolence have also been reported with overdoses.

In the event of overdosage, treatment should be started immediately.

Treatment is symptomatic and supportive. Haemodialysis is not an effective means of removing loratadine or its metabolite from the body.
