What is sulpiride prescribed for?

Sulpiride is not approved by the FDA for use in the United States. Internationally, it is used primarily to treat patients with schizophrenia. Antipsychotic medications like sulpiride may also be used to treat a range of psychiatric disorders including depression, obsessive-compulsive disorder, post-traumatic stress disorder, personality disorders, Tourette's syndrome, autism, and dementia.^[2]

How does sulpiride work?

Sulpiride works similarly to other antipsychotic drugs, in the sense that it blocks the activity of a brain chemical called dopamine. People who display psychotic symptoms associated with schizophrenia are believed to have elevated dopamine levels. By blocking dopamine activity, sulpiride can treat symptoms of schizophrenia. Sulpiride is also believed to have antidepressant effects.^[1] 

How is sulpiride usually taken?

In most cases, sulpiride is taken orally in tablet form. A common sulpiride tablet contains 200 mg of the drug. A typical starting dose for adults is 400 to 800 mg daily, taken as one to two tablets twice per day.^[1]

The ideal daily dose of sulpiride will vary based upon a patient’s unique needs. Individuals with positive symptoms of schizophrenia, such as hallucinations, typically benefit from higher doses and may need up to 1,200 mg of sulpiride per day. Those with primarily negative symptoms, such as flat affect, typically do well with 800 mg per day.^[1] A prescribing physician will determine the best dose for a patient’s situation. 

How long does sulpiride stay in your system?

The half-life of sulpiride is around 8 hours. This means that it will be eliminated from the body in about 32 to 40 hours, or around a day and a half.^[1]

Sulpiride should be stored at room temperature, away from excessive heat. It should not be stored at temperatures above about 77 degrees Fahrenheit.^[1] 

What to do if you overdose on sulpiride

Fatal sulpiride overdoses are rare, but it’s still important to exercise precaution and be aware of sulpiride overdose signs. Overdoses are most common when sulpiride is mixed with other substances.^[1]

If you or someone you know shows signs of sulpiride overdose, seek medical attention immediately. Medical treatment may be needed to reverse side effects of sulpiride overdose, and it’s important to be medically monitored for complications like irregular heartbeat.^[1]
