mtr-prochlorperazine-addiction

Prochlorperazine is the generic medication available as the brand names, Compro and Procomp. It is a phenothiazine antipsychotic drug that is used to treat the symptoms of schizophrenia. Prochlorperazine has been found to be effective for treating generalized non-psychotic anxiety as well. It can also be effective in treating severe nausea and vomiting, and several other conditions. Like many other prescription medications, prochlorperazine can be abused and may even lead to addiction. 

How is Prochlorperazine Abused? 

While prochlorperazine doesn’t deliver the same euphoric high that many abused drugs do, it is still abused. It does alter mood and perception, which has increased its misuse among recreational users. Taken in large doses outside of medical instructions can lead to accidental overdose, and prochlorperazine overdose can be life-threatening. When it is taken over a long period of time, even when it’s taken as directed, it can be damaging to body organs. Additionally, prochlorperazine use can lead someone to develop a physical tolerance to the drug, and drive them to use more, take it more often than prescribed, and ultimately, to seek more of the drug or other drugs as a substitute. 

What Are Side Effects of Prochlorperazine?

While it is quite effective when taken as directed for the conditions it is designed to treat, prochlorperazine does have some side effects that may occur. Those side effects include:

What Drug Interactions Are Dangerous with Prochlorperazine?

Withdrawal from Prochlorperazine

Like some other medications, when prochlorperazine is taken in high doses or for a prolonged period of time, it can lead to tolerance, which can become physical dependence. At that point, if the drug is stopped abruptly, the individual will experience withdrawal symptoms, including but not limited to: 

  • Anxiety
  • Nausea, vomiting, or diarrhea
  • Dizziness
  • Tremors or shaking
  • Schizophrenia-like symptoms, including delusions and hallucinations

Is There Treatment for Prochlorperazine Addiction?

Prochlorperazine is not usually addictive, however, individuals can become physically dependent on the medication, and it can be abused. Psychological addiction can happen with prochlorperazine, which means abusers may show addictive behaviors like obsessing about getting and using the drug, not taking part in activities and relationships that used to be pleasurable, and seeking more of the drug from one or more doctors. 

There is treatment for prochlorperazine dependence and addiction. It’s recommended that individuals who have been using the medication in high doses or for a prolonged period should seek medical help to stop using it. It may be recommended that individuals attend a medically supervised detox program to rid their bodies of prochlorperazine safely and comfortably.
