How will Fenistil Drops help?
Fenistil’s active ingredient, dimetindene maleate is an antihistamine with a well established heritage of more than 50 years.
When ingested, the drops act internally, providing a rapid onset of action.
Dimetindene maleate blocks the action of histamine, which is a substance released by the body during allergic reactions.
By preventing histamine to bind to the histamine receptors …
…it helps to reduce the associated symptoms of allergies such as skin rash (dermatosis), itching (pruritus), hay fever or other allergic forms of rhinitis.
