Keep the medicine in its original packaging until it is time to take it.
If the patient takes the medicine out of its original packaging it may not keep well.
Keep the medicine in a cool dry place where the temperature will stay below 25°C.
Do not store the medicine, or any other medicine, in the bathroom or near a sink. Do not leave it on a window sill or in the car. Heat and dampness can destroy some medicines.
A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.
