Pimozide - Benefits, dosage and side effects

Pimozide is a drug commonly used to relieve symptoms of tics, which are repetitive movements or speech that are out of control in people with Tourette's syndrome. In addition, this drug is also used to treat several mental disorders, such as schizophrenia and hypochondria

Pimozide works by blocking dopaminergic receptors in the nervous system. Thus, this drug can reduce the symptoms of Tourette's syndrome and certain types of mental disorders that are thought to occur due to the increased work of dopamine in the brain.

However, keep in mind that this medication does not cure the underlying disease.

Dosage and Instructions for Use of Pimozide

How to Take Pimozide Correctly

Take pimozide according to the doctor's recommendations and the instructions on the medicine package. Do not increase or decrease the dose without consulting your doctor first. Also, do not stop treatment with pimozide suddenly, as this may make your condition worse.

Pimozide can be taken before or after meals. Try to take this medicine at the same time every day. If you forget to take pimozide, take it as soon as you remember. If it is near the time of your next dose, ignore the missed dose and do not double the pimozide dose to make up for the missed dose.

Store pimozide tablets at room temperature and place in a closed container. Keep the medicine away from direct sunlight and keep it out of reach of children.

Interaction of Pimozide with Other Drugs

The following are a number of interactions that can occur if pimozide is taken with certain drugs:

  • Increased risk of extrapyramidal symptoms if taken with antiemetic drugs (to treat vomiting), such as metoclopramide
  • Increased risk of brain damage if taken with sibutramine
  • Increased risk of electrolyte imbalance if taken with diuretic drugs
  • Less effectiveness of levodopa
  • Increased risk of dangerous heart rhythm disturbances if taken with macrolide antibiotics, protease inhibitors, antiarrhythmics, azole antifungals, or tricyclic antidepressants and SSRIs

Pimozide may interact with grapefruit and alcohol. If eaten with or near grapefruit, pimozide's effect on the body may increase, increasing the risk of overdose. Meanwhile, if consumed with alcohol, the effect of decreasing brain function by alcohol can increase.
