Hi sudheer, If your mother has eczema, surfaz being an antifungal cream would not work. The best treatment would be keep the area moisturised. Using cream containing urea and lactic acid would help( moisturex or cotaryl). Also using a mild bathing bar like dove, cetaphil or pears would help. Sometimes foot wear or synthetic, woolen socks also aggravate eczema and that should also be prevented. Apart from that during her acute flares she might use a mild steroid cream along with oral antiallergic to treat the lesion. Once the phase is over, she might continue with general recommendations I have mentioned above. Sometimes to prevent steroid over use, tacrolimus is also prescribed. Consult a dermatologist to get the diagnosis confirmed, so that appropriate treatment can be started. Take care.
