JML Hayfever Relief 50 micrograms Nasal Spray

Boots Hayfever Relief 50 microgram Nasal Spray (Beclometasone Dipropionate)

Each spray contains: Beclometasone Dipropionate 50 micrograms

Nasal spray suspension

Hayfever Relief Spray is indicated for the treatment and prevention of seasonal and perennial allergic rhinitis, hayfever and vasomotor rhinitis. The drug has a potent anti-inflammatory effect within the respiratory tract.

Hayfever Relief Spray for intranasal administration only.

The minimum effective dose according to individual response should be used at which the control of symptoms is maintained (200 to 400 micrograms/day)

Adults and children:

There is insufficient clinical data at present to support the recommended use of this product in children under the age of six.

The recommended dosage for adults and children is two sprays into each nostril twice daily. In some cases a single spray into each nostril three or four times a day may be the preferred dosage regimen. When good effect has been achieved the dosage may be reduced to one spray into each nostril twice a day.

The total daily dose should not normally exceed eight sprays (400 micrograms/day).

For full therapeutic benefit, regular use is essential. Furthermore, it should be explained to the patient that maximum relief may not be obtained with the first few doses and the patient's co-operation to comply with the regular dosage schedule should be sought.

Hayfever Relief Spray is contra-indicated in patients with a history of hyper-sensitivity to any of the components.

Nasal passage infections and paranasal sinuses should be appropriately treated. Hayfever Relief Spray may be used in conjunction with other medicaments if required.

Caution should be exercised whilst transferring patients from systemic steroid treatment to Hayfever Relief Spray if there is doubt that their adrenal function is impaired.

Hayfever Relief Spray will control seasonal allergic rhinitis in most cases. However, an abnormally heavy challenge of summer allergies, may in certain situations, necessitate appropriate additional therapy, especially to control eye symptoms.

Systemic effects of nasal corticosteroids may occur particularly at high doses prescribed for prolonged periods. Growth retardation has been reported in children receiving nasal corticosteroids at licensed doses.

It is recommended that the height of children receiving prolonged treatment with nasal corticosteroids is regularly monitored. If growth is slowed, therapy should be reviewed with the aim of reducing the dose of nasal corticosteroid, if possible, to the lowest dose at which effective control of symptoms is maintained. In addition, consideration should be given to referring the patient to a paediatric specialist.

Treatment with higher than recommended doses may result in clinically significant adrenal suppression. If there is evidence for higher than recommended doses being used then additional systemic corticosteroid cover should be considered during periods of stress or elective surgery.

None known.

The use of Beclometasone Dipropionate in pregnancy requires that the benefits of the drug be weighed against the possible hazards. It should be noted that the drug has been in widespread use for many years without apparent ill consequence.

Safety in pregnancy has not been established. Corticosteroid administration to pregnant animals can cause abnormalities of foetal development including cleft palate and intra uterine growth retardation. Therefore there may be a very small risk of such effects in the human foetus.

Lactation:

The use of Beclometasone Dipropionate in mothers breast-feeding their babies requires that the therapeutic benefits of the drug be weighed against the potential hazards to the mother and baby.

No specific studies examining the transference of Beclometasone Dipropionate into the milk of lactating animals have been performed. It is reasonable to assume that Beclometasone Dipropionate is secreted in milk, but at the dosages used for direct intranasal administration there is low potential for significant levels in breast milk.

None known.

Systemic effects of nasal corticosteroids may occur, particularly when prescribed at high doses for prolonged periods. Such effects may include hypothalmic-pituitary-adrenal (HPA) suppression and growth retardation in children.

Rare cases of nasal septal perforation have been reported following the use of intranasal corticosteroids.

Rare cases of raised intra-ocular pressure or glaucoma have been reported.

As with other nasal sprays, dryness and irritation of the nose and throat, unpleasant taste and smell and epistaxis have been reported rarely.

The only harmful effect that follows inhalation of large amounts of the drug over a short time period is suppression of the hypothalmic-pituitary-adrenal (HPA) function. No special emergency action need be taken. Treatment with a Hayfever Relief Spray should be continued at the recommended dose. HPA function reverses in one or two days.

ATC Code R01AD01

Beclometasone Dipropionate is a glucocorticoid. It is a synthetic corticosteroid esterified at the 17 position and is more potent topically than systemically. This drug is currently only used topically for it's anti-inflammatory activity. In addition to the local anti-inflammatory action it exerts it also has immunosuppressive activity. There are a number of factors contributing to the mechanisms behind these actions. Firstly and foremost the drug inhibits the adherence of neutrophils and monocyte-macrophages to the capillary endothelial cells of the inflamed area. Secondly it obstructs the effect of macrophage migration inhibitory factor. Finally, Beclometasone Dipropionate also decreases the activation of plasminogen to plasmin and by inhibition of phospholipase A₂ activity, it reduces the formation of prostaglandins and leukotrienes in the local tissue. (SPC pharmacokinetics).

The greater part of any drug administered by inhalation is ultimately swallowed after being deposited in the mouth and oro-pharnyx. It has been shown that when 4mg Beclometasone Dipropionate was administered to man as a microfine suspension over 90% of the drug was absorbed. The rate of absorption is slow, peak serum levels being attained at about 3 to 5 hours after administration.

Beclometasone Dipropionate is widely distributed in the body tissues. It is found in the liver, in the kidney and in white blood cells. It is 87 per cent bound to human plasma protein (cortisol binds 90%).

Beclometasone Dipropionate is hydrolysed after oral administration by tissue and faecal esterases in vitro. It is therefore probable that the Beclometasone Monopropionate and Beclometasone present in faeces after oral administration result from hydrolysis of unabsorbed drug by gut esterases, and that the polar metabolites found in human faeces probably arise from the biliary excretion of metabolites of absorbed drug.

It is thought likely that any absorbed steroid is converted to pharmacologically inactive metabolites Beclometasone-17-propionate, Beclometasone and unidentified polar metabolites during its passage through the liver (first pass effect).

Studies using tritiated Beclometasone Dipropionate show that after oral administration 10-15% of the dose was recovered in the urine as metabolites over a period of 72 to 96 hours. Faecal excretion accounted for 37% to 47% of a 4 mg dose.

No data is available on the toxic effects of Beclometasone Dipropionate but these are likely to be similar to toxic effects reported for other halogenated topical corticosteroids. Toxic effects of corticosteroids in acute toxicity studies in mouse and rat include reduction in adrenal weight, liver changes, lung consolidation and gastrointestinal effects. These are dose related, the more potent the topical steroid the greater the effect; there is no evidence to suggest that these findings have any clinical relevance in man.

Potential carcinogenic effects have been found in mice following prolonged topical application of potent corticosteroids, but there is no evidence for carcinogenicity occurring in man. No data for Beclometasone is available. Halogenated topical corticosteroids have been found to be teratogenic in mice but the relevance of this in man is unknown.

Hayfever Relief Spray is supplied in a white plastic (high density polyethylene) bottle fitted with a screw on pump covered by a dustcap. The bottle provides 200 sprays.

Method of Administration

1. Remove the dust cap. Shake the bottle gently

2. On first using the nasal spray, prepare for use by pressing down on the white collar using both your index and middle fingers. Keep the base supported with your thumb. Continue to press down until the collar stops and then allow it to return to it's original position. Repeat this action until a fine spray appears. The first five attempts to produce a spray should be allowed to go to waste. Now the spray is ready to use.

3. To use the spray, first blow your nose gently. Closing one nostril off bend your head forward slightly. Hold the bottle upright and carefully insert the applicator into the other nostril.

4. Slowly begin to breathe in through your nose and whilst doing so press down firmly on the white collar to produce a fine spray inside your nose. Breathe out through your mouth.

5. Repeat steps 3 and 4 to squirt a second spray in the same nostril. Wash the nozzle frequently with warm water. This will prevent it from getting blocked. If the pump has not been used for a short period of time, re-priming may be necessary (see step 2 above).
