My wife, aged 45, had continuous bleeding many days during her monthly periods and as per the advise of the doctor she takes Tab- Registrone continuously since last six months. Colour of her face became black ( only face). She was under the treatment for sun burn and found no improvement. Presently she is under the treatment of a Cosmatolagist and taking medicine since last one month for allergy and taking tab - Ciplactin & Lotion - lacticare HC 1% . Is it because of Tab Rgistrone ?.
