3 Proper usage

To use Lorzone properly, you must follow all instructions given by your doctor.

Use and dosage in children must be determined by your healthcare professional. If your child is being prescribed this medication, take care with the dosage and make sure they are given the right amount at the right time each day.
A missed dose should be taken as soon as possible. However, skip the missed dose and go back to your regular dosing schedule if it is almost time for your next one.

Store the medicine in a closed container at room temperature, away from heat, moisture, and direct light, and do not freeze. Keep out of reach of children. Dispose of any outdated or expired drugs and ask your healthcare professional for the proper method of disposal. Make sure you peruse the label for the expiration date and throw out any remaining tablets past that date.
