Tigan is used to treat nausea and vomiting in adults. It is often prescribed when other antiemetic medications have not been effective or are contraindicated. Common situations include postoperative nausea and vomiting, as well as nausea associated with inner ear disorders.
Tigan acts on the chemoreceptor trigger zone (CTZ) in the brain, which is responsible for triggering the vomiting reflex. By blocking dopamine receptors in this area, it helps reduce nausea and prevent vomiting signals from being sent to the stomach.
Tigan is available by prescription only. Common side effects may include drowsiness, dizziness, and headache. It should be used with caution in patients with Parkinson's disease or those taking other medications that affect dopamine. The injectable form should not be given to pediatric patients. Always follow your healthcare provider's instructions and inform them of all medications you are taking.
