What is Naltrexone (Generic Revia) and what are its uses?

Revia is an antihistamine. Antihistamines work against the naturally occurring chemical histamine in your body.

Revia is used to prevent sneezing, runny nose, itching and watering of the eyes, and other allergic symptoms.

How does Naltrexone (Generic Revia) Works (Mechanism) ?

Revia belongs to a group of medicines called non-sedating antihistamines.

Histamine is a chemical produced by the body. Revia is stored in cells (mast cells) in almost all tissues of the body. When the body reacts to a foreign substance (an allergen e.g. flower pollen), the mast cells release their stores of histamine.

Revia acts by blocking the binding of histamine to receptors in the body. Revia does not prevent the actual release of histamine from mast cells. By blocking the binding of histamine, the release of other chemicals and increased blood supply to the area is prevented or decreased. This results in prevention or relief of the typical symptoms of an allergic reaction.

Histamine may be released from and act in a small (localised) area of the body e.g. the nose. Alternatively, histamine can result in a serious or complete body reaction e.g. anaphylactic reaction. Revia is only useful for the prevention or relief of localised or less serious allergies such as an itchy rash (rather than very serious allergic reactions).
