For most, nausea symptoms will typically clear on its own. For others nausea can be a daily occurrence and may require medication to help reduce the symptoms of nausea.

Stemetil 5mg tablets are an effective nausea treatment which can be purchased online from Medicine Direct. Stemetil contains prochlorperazine which is a first line treatment option for nausea.

What are Stemetil 5mg tablets?

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

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.
