How does Ondenstar syrup work?

Ondenstar syrup is a medicine that stops nausea and vomiting. It works by blocking serotonin, a chemical in your body that can trigger these symptoms. It's taken by mouth, and most of it is broken down in your liver before it reaches your bloodstream. A small amount leaves your body unchanged in your pee. How well it works and how long it stays in your body differs depending on your age and gender; women absorb it faster and keep it longer than men, and older people process it more slowly. Taking more doesn't necessarily make it work better.

Serious side effects are rare but possible, including severe allergic reactions (like trouble breathing), an irregular heartbeat (that could be life-threatening), a condition called serotonin syndrome (which involves confusion and other symptoms), chest pain, and problems with your gut. Your doctor may need to monitor you closely if you take this medicine. If you experience any of these side effects, stop taking the medicine immediately and contact your doctor.
