What are steroids? • Essentially hormones • Glucocorticoids/ mineralcorticoids • Naturally formed in the adrenal cortex • Natural glucocorticoids maintain normal blood sugar and assist the body to recover in times of stress.
Why Topical Steroids ? • To gain control of signs and symptoms of inflammatory skin disease • Achieve maximum efficacy with minimal side effects.
Action of Topical Steroids • Anti-inflammatory • Immunosuppressive • Vasoconstrictive • Anti-mitotic – decrease proliferation • Readily penetrate the dermis “Reduce inflammation and make the skin less sore and itchy”
Steroid Phobia • Present in health care professionals, patients and carers. • A reluctance to use prescribed topical steroids due to perceived side effects • Reassurance is essential to gain full concordance with treatment. REMEMBER: Appropriate topical steroid use limits potential side effects almost entirely.
Potential side effects Cutaneous Thinning / Atrophy Hypopigmentation Striae Telangietasia Tachyphylaxis, Infections, Perioral dermatitis, Contact dermatitis, Hirsutism, Monomorphic acne or rosacea N.B Epidermal thinning does occur within 1-3 weeks of tx with potent or very potent steroids normal skin but reverses within 4 weeks of stopping
Potential Side Effects : systemic • These are RARE and ALWAYS AVOIDABLE • Due to systemic absorption of the steroid
Adverse effects : systemically • Osteoporosis • Muscle atrophy • Cushings Syndrome • Inhibition of growth (children) • Cataracts • Masking of infection • Hypoglycaemia
Which steroid?- factors to consider • Age /potency – adult, adolescent or child • Site – absorption increased at certain sites • Extent- localised or generalised • Base- creams or ointments? • Method- frequency of application / occlusion • Experience of use - dexterity
