Fluocinonide 0.05% w/w
3 PHARMACEUTICAL FORM
Ointment
4 CLINICAL PARTICULARS
4.1 Therapeutic indications
Metosyn is suitable for treating a wide variety of local inflammatory, pruritic and allergic disorders of the skin. It is indicated in the following conditions:
Eczema and dermatitis: atopic eczema, seborrhoeic dermatitis, discoid eczema, contact dermatitis, neurodermatitis. Prurigo, psoriasis (excluding widespread plaque psoriasis). Lichen planus. Discoid lupus erythematosus.
Metosyn Ointment with its emollient effects, is particularly suitable for dry scaly lesions.
4.2 Posology and method of administration
It is recommended that Metosyn is used undiluted.
Adults
A small quantity of Metosyn Ointment should be applied three to four times daily to the affected area and massaged well in.
Once improvement is apparent, usage may be reduced to twice or even once daily.
Children
Under 1 year: Metosyn preparations are not advised in the treatment of children under 1 year of age.
Over 1 year: As adult dose, however it is recommended that treatment should not normally be extended beyond 5 days and occlusion in such cases should not be used.
Elderly
As adult dose.
4.3 Contraindications
Metosyn is contraindicated in rosacea, acne and peri-oral dermatitis. As with all topical steroids, Metosyn is contraindicated in tuberculous, syphilitic, fungal and viral infections of the skin. The product should not be used for napkin eruption or anogenital pruritus.
4.4 Special warnings and precautions for use
Long-term continuous topical steroid therapy can produce atrophic skin changes and dilation of the superficial blood vessels particularly when occlusive dressings are used or where skin folds are involved. Prolonged use of topical steroids or treatment of extensive areas, even without occlusion, can result in sufficient absorption of the steroid to produce the features of hypercorticalism and underlying adrenal suppression, especially in infants and children.
It is recommended that treatment on the face should not normally be extended beyond 5 days, and occlusion in such cases should not be used.
Where there is bacterial infection associated with an inflammatory skin condition, Metosyn should only be administered if adequate antibacterial cover is also given.
When using topical steroids to treat psoriasis there are risks of rebound relapse following the development of tolerance, and of generalised pustular psoriasis. Impairment of the barrier function of the skin may lead to local and systemic toxicity. Careful patient supervision is important.
Treatment should be discontinued if unfavourable reactions are seen.
Absorption is greatest where the skin is thin or raw.
4.5 Interaction with other medicinal products and other forms of interaction
None known.
4.6 Fertility, Pregnancy and lactation Pregnancy
There is inadequate evidence of safety in human pregnancy. Topical administration of steroids to pregnant animals can cause abnormalities of foetal development, including cleft palate and intrauterine growth retardation. There may therefore be a very small risk of such effects on the human foetus.
Lactation
Topical steroids should not be applied to the breasts prior to nursing. When topical steroid treatment is considered necessary for other parts of the body, both the amount applied and the length of treatment should be minimised.
4.7 Effects on ability to drive and use machines
No precautions are required.
4.8 Undesirable effects
With Metosyn side effects are extremely rare but, as with all topical steroids, the occasional patient may show an adverse reaction such as hypersensitivity. Irritation at the site of application may occur infrequently. Extensive treatment, particularly involving occlusive dressings or where skin folds are involved, can result in both local atrophic changes, such as striae, skin thinning and telangiectasia, and systemic effects such as adrenal suppression.
The use of topical steroids on infected lesions, without the addition of appropriate anti-infective therapy, can result in the spread of opportunist infection.
The eyes should be avoided.
Local side effects include contact dermatitis, perioral dermatitis, acne, or worsening of acne or acne rosacea, mild depigmentation which may be reversible and hypertrichosis.
Reporting of suspected adverse reactions
Reporting suspected adverse reactions after authorisation 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 via the national reporting system in the United Kingdom: Yellow Card Scheme Website: www.mhra.gov.uk/yellowcard
4.9 Overdose
A 25 g tube of Metosyn contains 12.5 mg of fluocinonide. Toxic effects are not likely to occur following accidental ingestion. Similarly, the components of the vehicles, singly or collectively, have not been shown to produce toxic effects in these quantities.
5 PHARMACOLOGICAL PROPERTIES
5.1 Pharmacodynamic properties
Fluocinonide is a synthetic anti-inflammatory corticosteroid. Its mechanisms of action are related to vasoconstriction and suppression of membrane permeability, mitotic activity, the immune response and release of inflammatory mediators.
5.2 Pharmacokinetic properties
The extent of percutaneous absorption of fluocinonide is determined by many factors including the vehicle, the integrity of the epidermal barrier and the use of occlusive dressings. Following absorption, fluocinonide is metabolised primarily in the liver and excreted by the kidneys.
5.3
Preclinical safety data
Fluocinonide is a drug on which extensive clinical experience has been obtained. All relevant information for the prescriber is provided elsewhere in the Summary of Product Characteristics.
