What is Prochlorperazine?
Prochlorperazine is an anti-sickness medication that can treat nausea, labyrinthitis, Ménière's disease, and BPPV, commonly referred to as vertigo.
Labyrinthitis is the inflammation of part of the inner ear called the labyrinth. The eighth cranial nerve (vestibulocochlear nerve) may also be inflamed. It typically causes symptoms such as nausea, vertigo, tinnitus, and/or hearing impairment. It’s typically caused by a bacterial or viral infection, so you’d need treatment for that in addition to Prochlorperazine for nausea and vertigo.
Benign Paroxysmal Positional Vertigo, or BPPV, is commonly known as vertigo, and it’s a false perception of movement when there isn’t any. It may cause you to feel like you’re going to fall or like the room is spinning. There are other causes for vertigo, but BPPV is the most common. You might need to take antihistamine alongside anti-sickness medication, so speak to our clinicians about it so they can recommend the best course of treatment.
Ménière's disease is a disorder of the inner ear that causes symptoms including nausea and vertigo. It may lead to you losing your balance completely and falling over.
How does Prochlorperazine work?
Prochlorperazine works by blocking the action of dopamine from sending nausea signals to your brain. Dopamine is a hormone, usually referred to as a chemical messenger, that is made by your own body, which uses it to send messages between nerve cells.
Prochlorperazine intercepts these messages, and in this case, the one that tells your brain it’s time to feel nauseous, effectively keeping you from feeling unpleasant sickness sensations.
What doses of Prochlorperazine are there?
There are two doses of Prochlorperazine available: 3mg and 5mg. Which one you’ll be prescribed will depend on how severe the condition you’re trying to treat is, your ability to tolerate the medication, your age, and what condition it’s being prescribed for.
You’ll normally be given a lower dose of Prochlorperazine to begin with, which can be adjusted once we’re sure the medication is right for you. If you’re not sure what dose you should be starting with, our clinicians will explain everything you need to know and give you the right treatment advice.
