What is Reglan?
Reglan is a type of medicine called an antiemetic that’s used to prevent nausea and vomiting. It can also help to relieve dizziness and headaches associated with inner-ear conditions like vestibular neuritis or labyrinthitis.
Reglan is prescribed off-label when used to treat inner-ear conditions. This means that while all the evidence points to them being a safe and effective treatment for nausea caused by inner-ear conditions, it isn’t officially licensed for this purpose.
How does Reglan work?
Reglan blocks dopamine receptors in the area of your brain responsible for nausea and vomiting. By stopping signals from traveling to these receptors, Reglan should help to relieve feelings of nausea and prevent vomiting.[1]
There’s also evidence that Reglan can speed up how quickly food passes through your digestive system, which may also help to reduce feelings of nausea.
How do Reglan doses work?
Reglan comes in 5 mg and 10 mg tablets. The amount of Reglan you’ll take and for how long will depend on what you’re taking it for, and how severe your nausea is. Always follow your clinician’s instructions when using Reglan.
What is Reglan’s active ingredient?
