About Stemetil (Prochlorperazine) 5mg Tablets
  1. What are Stemetil 5mg tablets?

    Stemetil is a medication for treating the symptoms of nausea, vomiting and vertigo.

    Stemetil is the branded version of the nausea medicine prochlorperazine and contains the same active ingredient (Prochlorperazine Maleate), which is effective at treating the symptoms of nausea and vomiting.

    This medicine can be taken by adults and children over 1 year of age. You must have a prescription to buy Stemetil. 

    What is Stemetil used to treat?

    Stemetil is an anti-sickness medicine that can be prescribed for a number of different problems.

    You may be prescribed Stemetil if you suffer from issues such as:

    • Dizziness (vertigo)
    • Morning sickness
    • Travel sickness
    • Migraines
    • Ménière's disease

    Stemetil can also be prescribed as a short-term treatment for anxiety.

    Why is Stemetil recommended for nausea and vomiting?

    Clinical research shows that Stemetil's active ingredient, prochlorperazine, is a fast-acting and effective treatment for nausea and vomiting. It also gets to work quicker than similar medicines. 

    How does Stemetil work?

    Stemetil contains the active ingredient prochlorperazine maleate, which belongs to a class of drugs known as phenothiazine antipsychotics.

    It is believed to work by blocking the action of dopamine, which is a chemical in the brain. Doing this works to stop nausea messages from reaching the vomiting centre of the brain, which helps to relieve the feeling of nausea and the desire to vomit.

    Prochlorperazine maleate will start to work after around 30 to 60 minutes of being taken.

    Who can take Stemetil tablets?

    Do not take Stemetil if you are allergic to prochlorperazine or any of the other ingredients in this medicine (please see the Ingredients tab for details).
