Phenergan

Phenergan is a medication used to relieve nausea and motion sickness. It's commonly taken for everyday travel sickness and can also help reduce symptoms like vomiting and pain after surgery.

Nausea can be caused by a variety of things, such as acid reflux, migraine, or food poisoning. Figuring out the cause can help you avoid triggers or spot symptoms early on.

Phenergan contains promethazine hydrochloride, which is a type of medicine known as a phenothiazine. It helps by blocking histamine, a chemical your body makes too much of during an allergic reaction. So, in addition to treating nausea effectively, Phenergan is also used to ease allergy symptoms.

Phenergan reduces the impact of histamine by altering how brain chemicals function. Its active ingredient, promethazine, lessens the sensitivity of histamine receptors in the brain area linked to vomiting.

The tablets work by blocking these receptors, but they don't stop histamine from being released. This prevents the vomiting centre from being triggered by inflammation, which can help reduce nausea and relieve motion sickness.

Phenergan is available in 10mg, 20mg, and 25mg doses. The amount you need will depend on how your nausea or motion sickness is impacting you. A healthcare professional can guide you on the right dose for you and the maximum amount you can take daily.

To help prevent motion sickness, it's generally advised to take 25mg of promethazine one to two hours before you set off. You might also take it the night before travelling.

Phenergan is similar to other antihistamines used for nausea, like Buccastem M and Cyclizine. They all help with nausea and sickness but contain different active ingredients. Since antihistamines can affect people differently, you might find that one works better for you than another. It may take some trial and error to find the one that suits you best.

The amount of Phenergan you need will generally depend on how bad your nausea or travel sickness is. Your doctor will decide this after you've had a consultation.

Phenergan is seen as an effective treatment for nausea, much like other antihistamine medicines that address nausea.

Phenergan has been proven to be much more effective than a placebo.

You'll need a prescription to take Phenergan. This ensures the prescriber can confirm it's safe and appropriate for you. They'll also determine the right dose by considering how severe your symptoms are and what might be causing them.
