Hello; welcome to HealthcareMagic Diprofos is Betamethasone a corticosteroid and is helpful in conditions like severe allergic rash;psoriasis;even in case of seborrhoea ;anaphylaxis;shock etc.Since it is a steroid it is mainly used as an emergency treatment at least in injectable form and can be used as required in form of tablets.The treatment with Diprofos like all other corticosteroids should be gradually tapered to reduce the risk of getting more severe symptoms due to the sudden withdrawal effect.The dosage frequency depends on the severity of the condition and the treating doctor is the best person to decide.So please ask your husband to take it as advised by the doctor and slowly taper off once the condition is improved. Thanks
