In order to minimise the side effects of a topical corticosteroid, it is important to apply it thinly to the affected areas only. Topical corticosteroids should not be applied with an occlusive dressing to large areas of the body. Absorption is greatest on thin/raw skin, intertriginous areas, and under occlusion. Skin thinning is more likely if corticosteroids are applied under occlusion.
The label will state mild steroid.
Absorption of topical corticosteroids through the skin can rarely cause adrenal suppression and even Cushing's syndrome (see Section 4.8 'Undesirable effects' and Section 4.9 'Overdose'), depending on the area of the body being treated and the duration of treatment.
Avoid prolonged exposure on the face and keep away from the eyes. Use with caution on broken skin.
Prolonged use of compound preparations such as Timodine Cream can increase the likelihood of resistance and of sensitization. Mixing topical preparations on the skin should be avoided where possible; several minutes should elapse between application of different preparations.
Topical corticosteroids are not recommended for acne vulgaris, may worsen secondary infected lesions, and should not be used indiscriminately in pruritis.
Long term use of topical steroids can result in the development of rebound flares after stopping treatment (topical steroid withdrawal syndrome). A severe form of rebound flare can develop which takes the form of a dermatitis with intense redness, stinging and burning that can spread beyond the initial treatment area. It is more likely to occur when delicate skin sites such as the face and flexures are treated. Should there be a reoccurrence of the condition within days to weeks after successful treatment a withdrawal reaction should be suspected. Reapplication should be with caution and specialist advice is recommended in these cases or other treatment options should be considered.
Timodine Cream contains butylated hydroxyanisole (E320), cetostearyl alcohol, sorbic acid which may cause local skin reactions (e.g. contact dermatitis) and propylene glycol (E1520), which may cause skin irritation. Butylated hydroxyanisole (E320) may cause irritation to the eyes and mucous membranes. Timodine Cream also contains propyl hydroxybenzoate (E216) and methyl hydroxybenzoate (E218), both of which may cause allergic reactions, which may be delayed. Nystatin can rarely cause contact dermatitis, and allergic reactions can occur after use of benzalkonium chloride.
Instruct patients not to smoke or go near naked flames – risk of severe burns. Fabric (clothing, bedding, dressings etc) that has been in contact with this product burns more easily and is a serious fire hazard. Washing clothing and bedding may reduce build-up but not totally remove it.
The elderly
The skin of the elderly is often relatively atrophic so that local and systemic side effects of hydrocortisone are more likely.
Patients with hepatic failure
The reduced metabolism of hydrocortisone in patients with hepatic failure increases the theoretical risk of adrenal suppression.
Paediatric population
Avoid prolonged use in children.
Caution is required in dermatoses of infancy including nappy rash. Care should be taken as the nappy can act as an occlusive dressing and thus allow an increase in absorption of the steroid component of the cream.
In infants, long-term continuous topical steroid therapy should be avoided since this can lead to adrenal suppression even without occlusion. A course of treatment should not normally exceed seven days.
Use of hydrocortisone should be avoided in neonates. Any proposed use of hydrocortisone in neonates should be carefully assessed, as the high body surface area:weight ratio allows a proportionate increase in percutaneous absorption. Consideration should be given to the relative fragility of neonatal skin.
