I bought some medicine from Family Medicals chennai, the medicines as duplicate and did not have any effect to cure the problem. I also heard from others that the same thing happening with then too.
When I bought the same medicines from other store, it worked, All of them have the same complaint in our area and stopped purchasing from the medical store.
People wheo are unaware still keep buying from that store.
I would request the authorities to conduct a uninformed check at the store and take samples for verification.
Also need to check where the drugs are purchased from.

Thanks in Advance
