Along with expected sedative effects of relaxation and drowsiness ethchlorvynol can cause skin rashes, faintness, restlessness and euphoria. Early adjustment side effects can include nausea and vomiting, numbness, blurred vision, stomach pains and temporary dizziness. An overdose is marked by confusion, fever, peripheral numbness and weakness, reduced coordination and muscle control, slurred speech, reduced heartbeat.

It is addictive and after prolonged use can cause withdrawal symptoms including convulsions, hallucinations and memory loss. Due to these problems it is unusual for ethchlorvynol to be prescribed for periods exceeding seven days.

Ethchlorvynol is a member of the class of sedative-hypnotic tertiary carbinols such as methylparafynol. It is not a barbituric acid derivative. The systematic name of ethchlorvynol is usually given as ethyl 2-chlorovinyl ethynyl carbinol or 1-chloro-3-ethyl-1-penten-4-yl-3-ol. Its empirical formula is C₇H₉ClO. In the United States Abbott Laboratories used to sell it under the tradename Placidyl. Since Abbott and Banner Pharmacaps, which manufactured the generic version, discontinued production in 1999, ethchlorvynol is no longer available in the United States.
