Answer:
drug synergistic effect
Step-by-step explanation:
A drug synergistic effect happens, when interactions between two or more drugs cause the total effect to be greater as a whole. Drug interactions occur when two or more drugs (note that medical drugs also are taken into account) as their chemicals react with each other. Drug condition interactions may occur when an existing medical condition makes some drugs potentially harmful. Therefore advise is always to remember not driving under any of these conditions or experiencing syptoms associated to taking medication.
Usually the synergistic effect is harmful to the body and can lead to severe risks to health or dead. (The percentage of death rate by irresponsible driving often happens while the driver is under the effect )
