Daronrix - patient leaflet, side effects, dosage

1. WHAT DARONRIX IS AND WHAT IT IS USED FOR

Daronrix is a vaccine used in adults aged 18 to 60 years to prevent influenza (flu) in an officially declared pandemic. The vaccine works by causing the body to produce its own protection (antibodies) against the disease.

Pandemic flu is a type of influenza that occurs every few decades and which spreads rapidly to affect most countries and regions around the world. The symptoms of pandemic flu are similar to those of “ordinary” flu but are usually more severe.

• 2. BEFORE YOU RECEIVE DARONRIX

Daronrix should not be given:

• if you have previously had any allergic reaction to Daronrix, or any ingredient (including eggs, chicken protein, gentamicin sulphate (antibiotic)) contained in this vaccine. The active substances and other ingredients in Daronrix are listed at the end of the leaflet. Signs of an allergic reaction may include itchy skin rash, shortness of breath and swelling of the face or tongue. However, in a pandemic situation, it may be appropriate to give the vaccine, provided that facilities for resuscitation are immediately available in case of need.
