Should I Continue Taking Proanogen For Hair Fall, Are There Any Side Effects, And Will Hair Fall Return If I Stop?

Hi, I am 23 years old. I had the problem of hairfall and consulted a doctor. She prescribed proanogen tablets. I have been taking the med since a month and there is good result. Should I continue taking the medicine? Is there any side effects in using these tablets? Will there be any hairfall again if i stop the med?
