If your child runs out of eg. cough syrup, your house has got an exactly the same medicine prescribed to your child previously, but this is prescribed to an adult but unopened, would you feed it to your child? At the dosage stated for your child @3.5ml.

If u have given the same medication to ur child before and at the right dosage, I will give. I had done it before and at a safe dosage. At times, I will get more med for standby so I don't have to see pd for common sickness unless it is v serious and child has been unwell for a prolonged period.
