Driving under the influence of medication can be dangerous if these affect the **physical and mental state** of the driver. Some medications, such as analgesics, antitussives, antihistamines, and psychotropic drugs, can cause side effects like **drowsiness, dizziness, loss of reflexes, and confusion**. These effects can decrease the ability to drive safely.

It is important for people taking medication to consult with a doctor to know if it is safe to drive. Additionally, they should be well aware of the effects of the medications they are taking and avoid driving if they feel unwell. It is also crucial not to mix medications with alcohol, as this can increase the negative effects.

Therefore, it is permitted to drive under the influence of medication **only if the physical and mental state of the driver is not affected**. If the side effects compromise safety at the wheel, it is better to avoid driving.
