what is Avomine and what it is used for
Avomine tablets contain 25mg promethazine as the active ingredient. This is a type of medicine called an antihistamine.
Promethazine works by stopping histamine from binding to its receptors in an area in the brain known as the vomiting centre. The vomiting centre is responsible for causing feelings of sickness and for the vomiting reflex. It is activated when it receives nerve messages from the vestibular apparatus in the middle ear.
The vestibular apparatus provides constant feedback to the brain about the position of our body. When something disturbs the vestibular apparatus, such as movements of the head when travelling by boat or car, nerve signals are sent from the vestibular apparatus to the vomiting centre. This can cause the symptoms of motion sickness, such as nausea, dizziness or spinning sensations (vertigo) and vomiting.

Before you use Avomine
- Avomine tablets can make some people feel drowsy, dizzy, confused or disorientated and this may reduce your ability to drive or operate machinery safely. Do not drive or operate machinery until you know how this medicine affects you and you are sure it won’t affect your performance. If your child is affected in this way they should avoid potentially hazardous activities such as riding bikes. You should not leave your child unattended after giving them this medicine.
- Avoid drinking alcohol while taking Avomine because this is likely to make the above effects more likely or worse.
- Avomine tablets may make your skin more sensitive to sunlight than usual, so you should avoid exposing your skin to direct sunlight or sunlamps until you know how your skin reacts. If you can’t avoid strong sunlight you should use a sunscreen lotion or make sure your skin is protected with clothing.
- This medicine may interfere with some pregnancy tests causing false negative or false positive results.
- If you are due to have any skin prick test to diagnose allergies you should stop taking Avomine at least 72 hours before the tests. This is because antihistamines can prevent or lessen the skin reactions that indicate an allergy, and so can make the test results unreliable.
Each tablet contains 25 mg of promethazine theoclate (the active ingredient), wheat starch, lactose, dextrin, talc and magnesium stearate. Avomine contains lactose and gluten
