Why is the the RED line on medicine pack?

You may have seen a RED LINE on some medicinal packs. The RED LINE indicates that this medicine cannot be purchased without doctor's prescription. The MInistry of Health has innovated this RED LINE. Also, the pharmacy is allowed to sell medicines with RED LINE only when a medical prescription is provided by buyers. This is the most important step taken regarding health of people. Now, it is our responsibilities to check RED LINE over medicine.
