What is an agent called that is given to counteract an unwanted effect of a drug?

Antidote
Analgesic
Stimulant
Sedative

The correct answer is: Antidote

An antidote is a substance used to counteract or neutralize the unwanted effect of a drug. This is often done in cases of drug overdose or adverse reactions. Option B, analgesic, is a type of pain reliever and has no effect on countering the effects of a drug. Option C, stimulant, increases the activity of the central nervous system and would not be used to counteract the effects of a drug. Option D, sedative, decreases central nervous system activity and may help with some adverse effects of a drug, but is not specifically designed to counteract them. Therefore, A is the best answer as it specifically refers to counteracting unwanted effects of a drug.
