Richie was stopped by police in December after she was seen driving the wrong way on a Los Angeles freeway.
It was her second charge of driving under the influence in four years.
She was given a 96-hour jail sentence with credit for six hours for time served. She was also given three years probation.
Police say that when they questioned Richie at the time of her arrest she failed a sobriety test and admitted that she had smoked marijuana and taken the painkiller Vicodin.
The alcohol charge was dropped as part of a plea deal with authorities.
Richie was accompanied to court by her boyfriend, Good Charlotte singer Joel Madden.
Celebrity magazines say she is three months pregnant.
Richie, who was calm inside court, left the building without speaking to reporters after a hearing which lasted about 30 minutes.
