Tacrolimus is non-steroidal immunosuppressant. It is indicated for treatment of refractory atopic eczema. It is sold under several brand names by different manufacturers. You will need to procure it from India since it is much cheaper. I suggest you purchase Mustopic Ointment brand that costs Rs. 140 for a 10 g tube. You can arrange to procure it from any good chemist shop in Delhi.
