When someone is sick, they take medicine to help them feel better. But sometimes, when they start feeling better, they may stop taking the medicine even if they haven't finished their prescribed course of treatment. This is called medication discontinuation.
Doctors give medicine to people for a specific amount of time based on the type of sickness they have. This is because they want to ensure that the person is completely cured and the infection or illness doesn't come back. Stopping the medicine before the treatment is completed can cause the illness to come back or make the person feel more sick.
Think of it like building a tower of blocks. Each block is like one dose of medicine. Once you start taking your medicine, you need to continue taking it until you finish all the blocks (doses). Just like the tower of blocks won't stand if you remove blocks before it's complete, your treatment won't be effective if you stop your medicine before your doctor tells you to.
So even if you feel better after a few days of taking medicine, it's important to keep taking it until the doctor says it's okay to stop. This helps to make sure that you get completely better and stay healthy.
