Hello doctor,

My mother is 49 years old. She is having blister kind of thing appearing laterally on her left foot, followed by itching, and release of water for the past two to three months. She did not take any medications for the same until now. Besides this, she is a patient of thyroid disorder for 20 years and is under Thyronorm 50 mg for the same.



Welcome to icliniq.com.

It is foot eczema with skin peeling. Use Fucidin cream twice daily for 10 days, Emoderm cream at daytime for 20 days, and Calosoft lotion after bath for 10 days.

Take tablet Zifi (Cefixime) 200 mg twice daily for five days, tablet Emanzen D (Serratiopeptidase and Diclofenac sodium) twice daily for three days (if pain).

Is she a diabetic? Excess contact with water? Any history of atopy or allergies, autoimmune diseases, or vesiculobullous disorders in the past? Any similar episode in the past? Excess scratching and rubbing of lesion? Any chronic illness, fever, or oozing? Any drug history or drug allergies in the past? Injury or trauma at the site? Please reply.

Thank you doctor,

She does not have diabetes and no excess contact with water with negative history for all except occasional allergic to painkillers.

Avoid provoking or triggering factors. Avoid drugs that cause reactions like painkillers, morphine, codeine, Ibuprofen (Brufen), Combiflam, Penicillin, Enalapril which cause generalized pruritus. Identify and remove the trigger factor.

Use antihistamine tablet Levocetirizine 5 mg twice daily for seven days will help in reducing itching. Ensure proper hygiene and avoidance of application of irritants. Avoid scratching or rubbing lesions in as it may cause secondary bacterial infection.

Use Fucidin (Fusidic acid) cream twice daily for 10 days (morning and evening), Emoderm cream at afternoon (on dry skin) for 20 days. Take tablet Zifi 200 mg twice daily for five days (if oozing present or bacterial infection). Apply Calamine lotion for a soothing effect on skin.
