1. Why am I using Telnasal Allergy Spray?

Telnasal Allergy Spray contains the active ingredient mometasone furoate monohydrate. Telnasal Allergy Spray belongs to a family of medicines called corticosteroids, which are used to help reduce inflammation.

Allergic Rhinitis (hayfever): Telnasal Allergy Spray is sprayed into the nose to help relieve symptoms that may occur with hayfever or other year round allergies, including stuffiness (congestion) in the nose, discharge, itching and sneezing. This medicine may also be used to help prevent these symptoms two to four weeks before the beginning of the pollen season.

There is no evidence that this medicine is addictive.

2. What should I know before I use Telnasal Allergy Spray?

4. How do I use Telnasal Allergy Spray?

How much to use

Hayfever and allergies in adults (including the elderly) and children 12 years of age and older:

  • Two sprays into each nostril once daily.
  • It may take 1-2 days for full effect.
  • Follow the instructions provided with the medicine.
  • Do not exceed the recommended dosage.
  • Consult your pharmacist or doctor if symptoms are not relieved within 7 days.
  • Once symptoms are controlled, reducing the dose to one spray in each nostril may be effective for maintenance.
  • Do not use for more than 6 months without the advice of your pharmacist or doctor.
  • Do not give to children under 12 years of age.

When to use Telnasal Allergy Spray

  • Telnasal Allergy Spray should be used once daily.

How to use Telnasal Allergy Spray

Your nasal spray has a dust cap which protects the nozzle and keeps it clean. Remember to take this off before using the spray and to replace it after use.

Do not pierce the nasal applicator.

If you are using the spray for the first time prime the pump by pumping the spray 10 times until a fine mist is produced.

If you have not used the pump for 14 days or more reprime by pumping 2 times.

  1. Shake the bottle gently and remove the dust cap.
  2. Gently blow your nose.
  3. Close one nostril and put the nozzle into the other nostril.
  4. Tilt your head forward slightly, keeping the bottle upright.
  5. Start to breathe in gently or slowly through your nose and whilst you are breathing in squirt a spray of fine mist into your nose by pressing down ONCE with your fingers.
  6. Breathe out through your mouth. Repeat step 5 to inhale a second spray in the same nostril.
  7. Remove the nozzle from this nostril and breathe out through the mouth.
  8. Repeat steps 3 to 7 for the other nostril. After using the spray, wipe the nozzle carefully with a clean tissue and replace the dust cap.

If you use too much Telnasal Allergy Spray

If you think that you have used too much Telnasal Allergy Spray, you may need urgent medical attention.

You should immediately:

  • phone the Poisons Information Centre
    (by calling 13 11 26), or
  • contact your doctor, or
  • go to the Emergency Department at your nearest hospital.

You should do this even if there are no signs of discomfort or poisoning.

5. What should I know while using Telnasal Allergy Spray?

Things you should do

If you become pregnant while you are using this medicine tell your doctor or pharmacist.

Tell any other doctors, dentists and pharmacists who are treating you that you are using this medicine.

If you are about to be started on any new medicine, tell your doctor, dentist or pharmacist that you are using this medicine.

If you are going to have surgery, tell the surgeon or anaesthetist that you are using this medicine.

See your doctor immediately if you notice the symptoms of severe bacterial infection. These symptoms may include fever, persistent face/tooth pain on one side of the face, swelling around the eye area, or worsening of symptoms after an initial improvement.

How long to use it

You can stop taking Telnasal Allergy Spray when you obtain relief from the symptoms. It can be restarted if the symptoms reoccur.

See your doctor or pharmacist if your symptoms are not relieved within 7 days.

Do not use for more than 6 months without the advice of your pharmacist or doctor.

Things you should not do

Do not give this medicine to anyone else, even if they have the same condition as you.

Do not use it to treat any other complaints unless your doctor tells you to.

If you forget to take it

If it is almost time for your next dose, skip the dose you missed and use your next dose when you are meant to. Otherwise, use it as soon as you remember, and then go back to use your medicines as you would normally.

Do not use a double dose to make up for the dose you missed.

Driving or using machines

This medicine generally does not cause any problems with your ability to drive a car or operate machinery.

Drug testing for sport events:

This product is a corticosteroid for intranasal administration; it is not a restricted drug for sports.

Corticosteroid may be detected in blood and in the urine during drug testing; thus prior written permission for its use may be required by some sport agencies.

Looking after your medicine

It is important to clean the nozzle regularly; otherwise, it may not work properly.

Remove the dust cap and gently pull off the nozzle. Wash the nozzle and dust cap in warm water and then rinse under a running tap. Do not try to unblock the nasal applicator by inserting a pin or other sharp object as this will damage the applicator and cause you not to get the right dose of medicine.

Allow the nozzle to dry. Push the nozzle back onto the bottle and replace the dust cap. The pump will need to be reprimed when first used after cleaning.

Follow the instructions in the carton on how to take care of your medicine properly.

  • Store below 25°C.
  • Do not freeze.
  • The bottle should be discarded after the labelled number of actuations or within 2 months of first use.

Store in a cool dry place away from moisture, heat or sunlight; for example, do not store it:

  • in the bathroom or near a sink, or
  • in the car or on window sills.

Keep it where young children cannot reach it.

For the full list of excipients, see Section 6.1 List of Excipients.

3 Pharmaceutical Form

Aqueous nasal spray.

4 Clinical Particulars

4.1 Therapeutic Indications

For the treatment of symptoms associated with seasonal allergic rhinitis and perennial allergic rhinitis and the prophylaxis of seasonal allergic rhinitis for up to 6 months in adults and children 12 years of age and over.

4.2 Dose and Method of Administration

Do not exceed the recommended dosage.
The effect of mometasone aqueous nasal spray 0.05% is not immediate. Full therapeutic benefit takes a few days to develop. Dosage should be administered as directed and not to be taken by the patients at will for symptomatic relief.

Allergic rhinitis.

In patients who have a history of moderate to severe symptoms of seasonal allergic rhinitis, prophylactic treatment with mometasone is recommended two to four weeks prior to the anticipated start of the pollen season.

Adults and children 12 years of age and over.

The usual recommended dose for prophylaxis and treatment is two sprays (50 microgram/spray) in each nostril once daily (total daily dose 200 microgram). Once symptoms are controlled, reducing the dose to one spray in each nostril (total daily dose 100 microgram) may be effective for maintenance.
After the first dose of mometasone, clinically significant improvement of symptoms was achieved within 12 hours in 28% of a group of patients (n = 190) with seasonal allergic rhinitis (median = 36 hours). However, the full benefit of treatment may not be achieved in the first 48 hours, therefore, the patient should continue regular use to achieve full therapeutic benefit.

Instructions to patients.

Shake container well before each use. Do not pierce the nasal applicator. After the initial priming of the mometasone aqueous nasal spray 0.05% pump (10 actuations, until a uniform spray is observed), each actuation delivers approximately 100 mg of mometasone furoate suspension, containing mometasone furoate monohydrate equivalent to 50 microgram of mometasone furoate. If the spray pump has not been used for 14 days or longer, it should be reprimed with 2 actuations, until a uniform spray is observed, before the next use.

Cleaning your nasal spray.

It is important to clean your nasal spray regularly, otherwise it may not work properly. Remove the dust cap and gently pull off the nozzle. Wash the nozzle and dust cap in warm water and then rinse under a running tap. Do not try to unblock the nasal applicator by inserting a pin or other sharp object as this will damage the applicator and cause you not to get the right dose of medicine. Allow to dry in a warm place. Push the nozzle back onto the bottle and replace the dust cap. The spray will need to be re-primed with 2 sprays when first used after cleaning.

Do not use.

1. Patients should not use Telnasal Allergy Spray for more than 6 months without the advice of a pharmacist or doctor.
2. Do not use Telnasal Allergy Spray in children under 12 years of age.

4.3 Contraindications

Patients with known hypersensitivity to mometasone furoate or any of the excipients.
Severe nasal infection, especially candidiasis.
Persons with haemorrhagic diathesis or with a history of recurrent nasal bleeding.
Use in children under 12 years of age.
Use for longer than six months without the advice of a doctor or pharmacist.

4.4 Special Warnings and Precautions for Use

Improvement should be seen within seven days of starting treatment. Treatment should be reassessed if there is no improvement within seven days of continuous use, or if symptoms have improved but are not adequately controlled after seven days of continuous use.
If signs or symptoms of eye pain and/or visual disturbance develop, discontinuance of mometasone nasal spray use or appropriate treatment may be required.
Mometasone aqueous nasal spray 0.05% should not be used in the presence of untreated localized infection involving the nasal mucosa.
Because of the inhibitory effect of corticosteroids on wound healing, patients who have experienced recent nasal surgery or trauma should not use a nasal corticosteroid until healing has occurred.
Following 12 months of treatment with mometasone aqueous nasal spray 0.05%, there was no evidence of atrophy of the nasal mucosa. Mometasone furoate tended to reverse the nasal mucosa closer to a normal histological phenotype. As with any long-term treatment, patients using mometasone aqueous nasal spray 0.05% over several months or longer should be examined periodically for possible changes in the nasal mucosa. If localized fungal infection of the nose or pharynx develops, discontinuance of mometasone aqueous nasal spray 0.05% therapy or appropriate treatment may be required.
Persistence of nasopharyngeal irritation may be an indication for discontinuing mometasone aqueous nasal spray 0.05%.
Mometasone aqueous nasal spray 0.05% should be used with caution, if at all, in patients with active or quiescent tuberculous infections of the respiratory tract, or in untreated fungal, bacterial, systemic viral infections or ocular herpes simplex.
Topical corticosteroids may be absorbed in amounts that can have systemic effects. Use of excessive doses may suppress HPA function. Physicians should be alert for evidence of systemic effects, especially in chronically treated patients.
However, there is no evidence of hypothalamic-pituitary-adrenal (HPA) axis suppression following prolonged treatment with mometasone aqueous nasal spray 0.05%. Patients who are transferred from long-term administration of systemically active corticosteroids to mometasone aqueous nasal spray 0.05% require careful attention. Systemic corticosteroid withdrawal in such patients may result in adrenal insufficiency for a number of months until recovery of HPA axis function. If these patients exhibit signs and symptoms of adrenal insufficiency, systemic corticosteroid administration should be resumed and other modes of therapy and appropriate measures instituted.
During transfer from systemic corticosteroids to mometasone aqueous nasal spray 0.05%, some patients may experience symptoms of withdrawal from systemically active corticosteroids (e.g. joint and/or muscular pain, lassitude and depression initially) despite relief from nasal symptoms and will require encouragement to continue mometasone aqueous nasal spray 0.05% therapy. Such transfer may also unmask pre-existing allergic conditions such as allergic conjunctivitis and eczema, previously suppressed by systemic corticosteroid therapy.
Patients receiving corticosteroids who are potentially immunosuppressed should be warned of the risk of exposure to certain infections (e.g. chickenpox, measles) and of the importance of obtaining medical advice if such exposure occurs.
Following the use of intranasal aerosolized corticosteroids, instances of nasal septum perforation or increased intraocular pressure have been reported very rarely.

Use in elderly.

No data available.

Paediatric use.

Telnasal Allergy Spray should not be used in children under 12 years of age.
Controlled clinical trials have shown that intranasal corticosteroids may cause a reduction in growth velocity in children. This effect has been observed in the absence of laboratory evidence of hypothalamic-pituitary-adrenal (HPA) axis suppression, suggesting that growth velocity is a more sensitive indicator of systemic corticosteroid exposure in children than some commonly used tests of HPA-axis function. The long-term effects of this reduction in growth velocity associated with intranasal corticosteroids, including the impact on final adult height, are unknown. The potential for "catch up" growth following discontinuation of treatment with intranasal corticosteroids has not been adequately studied.
The growth of children receiving intranasal corticosteroids should be monitored routinely (e.g. via stadiometry). The potential growth effects of prolonged treatment should be weighed against the clinical benefits and the availability of safe and effective non-corticosteroid alternatives. To minimize the systemic effects of intranasal corticosteroids, each patient should be titrated to his/her lowest effective dose.
However, no reduction in growth velocity was observed in a placebo-controlled clinical trial in which pediatric patients were administered mometasone aqueous nasal spray 0.05% 100 microgram daily for one year. The effects of treatment for periods of greater than one year have not been studied.

Effects of laboratory tests.

No data available.

4.5 Interactions with Other Medicines and Other Forms of Interactions

There have been no formal interaction studies performed.

4.6 Fertility, Pregnancy and Lactation

Effects on fertility.

As with other corticosteroids, at exposure levels associated with marked signs of systemic corticosteroid toxicity, mometasone furoate had progestogenic effects on the female reproductive tract and mammary glands. However, fertility was unimpaired in a reproductive toxicity study carried out in rats.
(Category B3)
In animal studies, small quantities of mometasone furoate were found to cross the placenta barrier. Like other corticosteroids, at doses associated with signs of systemic toxicity, mometasone furoate reduced fetal growth and was teratogenic in mice, rats and rabbits after subcutaneous or topical application. Higher doses had progestogenic effects in pregnant rats, associated with prolonged gestation, dystocia and reduced pup survival.
There are no adequate or well-controlled studies in pregnant women. Low levels of systemic mometasone have been measured following nasal administration of mometasone aqueous nasal spray 0.05%.
As with other nasal corticosteroid preparations, mometasone aqueous nasal spray 0.05% should be used in pregnant women only if the potential benefit justifies the potential risk to the mother or fetus. Infants born of mothers who received corticosteroids during pregnancy should be observed carefully for hypoadrenalism.
After oral administration, small quantities of mometasone furoate and/or its metabolites were transferred into the milk of lactating rats. There are no data on the extent of passage of mometasone furoate and/or its metabolites into the breast milk of women using mometasone furoate nasal spray 0.05%. As with other nasal corticosteroid preparation, mometasone should be used by lactating mother only if the potential benefit justifies any potential risk to the infant.

4.7 Effects on Ability to Drive and Use Machines

The effects of this medicine on a person's ability to drive and use machines were not assessed as part of its registration.

4.8 Adverse Effects (Undesirable Effects)

Adult population.

Treatment-related local adverse events reported in clinical studies include headache (8%), epistaxis (e.g. frank bleeding, blood-tinged mucus and blood flecks) (8% vs placebo 5%), nasal burning (2% vs placebo 3%), and nasal irritation (2% vs placebo 2%) and nasal ulceration, which are typically observed with the use of a corticosteroid nasal spray.
Epistaxis was generally self-limiting and mild in severity, and occurred at a comparable or lower incidence compared to other active control nasal corticoids used in clinical studies (up to 15%). The incidence of all other effects was comparable with that of placebo.
In the elderly, the more common adverse events were epistaxis (12% vs placebo 5%), headache (9% vs placebo 6%) and pharyngitis (4% vs placebo 2%).
In patients treated for nasal polyposis, the overall incidence of adverse events was comparable to placebo and similar to that observed for patients with allergic rhinitis.

Paediatric population.

In the paediatric population, the most common adverse effects were epistaxis (6% vs placebo 6%), headache (3% vs placebo 4%), nasal irritation (2% vs placebo 1%) and sneezing (2% vs placebo 4%).
Rarely, immediate hypersensitivity reactions (e.g. bronchospasm, dyspnea) may occur after intranasal administration of mometasone furoate monohydrate. Very rarely, anaphylaxis and angioedema have been reported.
Disturbances of taste and smell have been reported very rarely.
Growth suppression has been reported in association with administration of intranasal corticosteroids (see Section 4.4 Special Warnings and Precautions for Use, Pediatric use).

Acute rhinosinusitis.

In patients treated for acute rhinosinusitis, the overall incidence of adverse events was comparable to placebo and similar to that observed for patients with allergic rhinitis.
Treatment related adverse events reported most frequently in the mometasone 200 microgram twice daily group include epistaxis (3.7% vs. placebo 2.6%), diarrhoea (2.1% vs. placebo 0.8%), headache (1.7% vs. placebo 2.4%), nausea (1.7% vs. placebo 0.6%) and abdominal pain (1.7% vs. placebo 1.0%).

Reporting suspected adverse effects.

Reporting suspected adverse reactions after registration 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 at www.tga.gov.au/reporting-problems.

4.9 Overdose

Because the systemic bioavailability of mometasone aqueous nasal spray is low and has been estimated as < 1%, overdose is unlikely to require any therapy other than observation. Treatment can be reinitiated at the usual recommended dose.
Inhalation or oral administration of excessive doses of corticosteroids may lead to suppression of hypothalamic-pituitary-adrenal (HPA) axis function.
For information on the management of overdose, contact the Poison Information Centre on 13 11 26 (Australia).

5 Pharmacological Properties

5.1 Pharmacodynamic Properties

Mechanism of action.

Mometasone furoate is a topical glucocorticosteroid with local anti-inflammatory properties at doses that are not systemically active.
In studies utilising nasal antigen challenge, mometasone aqueous nasal spray 0.05% has shown anti-inflammatory activity in both the early- and late-phase allergic responses. This has been demonstrated by decreases (vs placebo) in histamine and eosinophil activity and reductions (vs baseline) in eosinophils, neutrophils and epithelial cell adhesion proteins.

Clinical trials.

Adult clinical program.

Allergic rhinitis.

The clinical program evaluated the efficacy and safety of mometasone aqueous nasal spray 0.05% in the prophylaxis and treatment of seasonal allergic rhinitis and the treatment of perennial allergic rhinitis. Five Phase I clinical studies evaluated the systemic safety and local tolerability of mometasone. Other clinical studies included:
One Phase II dose-ranging study conducted to determine the optimum dose for the Phase III program;
Seven Phase III studies designed to assess the safety and efficacy of mometasone in treating seasonal allergic rhinitis for 28 days (including two studies which evaluated the prophylactic efficacy of mometasone in preventing the symptoms of seasonal allergic rhinitis, and two which evaluated inflammatory response markers following nasal provocation with allergens); and
Five Phase III studies designed to assess the safety and efficacy of mometasone in the treatment of perennial allergic rhinitis for 12 weeks. Four studies investigated the long term safety and maintenance of therapeutic effect of mometasone over 52 weeks; one perennial allergic rhinitis study was conducted in the elderly population; and three open-label perennial allergic rhinitis studies included a "variable-dose group" in which he dose of mometasone varied from 100 to 400 microgram daily depending on symptoms.
During the course of the Phase II/III clinical program, 3120 patients (12 years of age and older) were treated with mometasone aqueous nasal spray 0.05%. The majority (65%) of patients was treated with 200 microgram once daily. The remainder received mometasone in a dose ranging from 50 microgram to 800 microgram once daily. A total of 712 patients were treated with mometasone for at least 6 months and 350 patients were treated for 12 months or longer.
The results of the efficacy studies demonstrated that mometasone aqueous nasal spray 0.05% 200 microgram/day was consistently superior to placebo in relieving the symptoms of both seasonal allergic rhinitis and perennial allergic rhinitis and was of comparable efficacy to other commonly used topical corticosteroid sprays. In the case of seasonal allergic rhinitis it is also superior to placebo in the prophylaxis of symptoms. In the long-term studies in perennial allergic rhinitis there was no evidence of any diminution of its efficacy over time.
After the first dose of mometasone, clinically significant improvement of symptoms was achieved within 12 hours in 28% of a group of patients (n = 190) with seasonal allergic rhinitis (median = 36 hours). However, the full benefit of treatment may not be achieved in the first 48 hours, therefore, the patient should continue regular use to achieve full therapeutic benefit.

5.2 Pharmacokinetic Properties

Systemic bioavailability of mometasone furoate was investigated in 24 healthy volunteers following intranasal administration of 400 microgram of the suspension. Mometasone was detectable in plasma (at sporadic time points) in only 4 of the 24 subjects, despite the use of a sensitive assay with a limit of quantitation of 50 picogram/mL. Thus, there were no relevant pharmacokinetic data for this dosage form.
Systemic absorption of mometasone furoate suspension administered as aqueous nasal spray, 200 microgram single dose, was measured using a sensitive assay with a lower quantitation limit of 0.25 picogram/mL. Mean C max was 5.77 picogram/mL (CV% 32) and mean AUC (0-12 hr) 29.6 picogram.hr/mL (CV% 37). When compared with dose adjusted PK data for IV mometasone administration from earlier studies with a quantitation limit of 50 picogram/mL and longer sampling duration, the estimated relative systemic (or 'absolute') bioavailability is < 1%. The bioavailability of mometasone following intranasal administration is low.
Systemic effects were not detected in adults, adolescents or children following the administration of mometasone furoate aqueous nasal spray.
Mometasone furoate suspension is very poorly absorbed from the gastrointestinal tract, and the small amount that may be swallowed and absorbed undergoes extensive first-pass metabolism prior to excretion in urine and bile.

5.3 Preclinical Safety Data

Genotoxicity.

Mometasone furoate is not considered to be genotoxic. There was no evidence of mutagenicity in in vitro tests which included tests for reverse mutation in Salmonella typhimurium and Escherichia coli and forward gene mutation in a mouse lymphoma cell line. Limited evidence of clastogenicity was obtained in Chinese Hamster ovary cells, although this finding was not confirmed in a second assay in Chinese Hamster lung cells in vitro, nor in vivo assays including a chromosomal aberration assay in mouse spermatogonia, a mouse micronucleus assay or in a rat bone marrow clastogenicity assay. Mometasone furoate did not cause DNA damage in rat liver cells.

Carcinogenicity.

No data available.
