Full Prescribing Info
Special Precautions
As with other vaccines, the administration of Twinrix Adult should be postponed in subjects suffering from acute severe febrile illness.
Syncope (fainting) can occur following, or even before, any vaccination as a psychogenic response to the needle injection. It is important that procedures are in place to avoid injury from faints.
It is possible that subjects may be in the incubation period of a hepatitis A or hepatitis B infection at the time of vaccination. It is not known whether Twinrix Adult will prevent hepatitis A and hepatitis B in such cases.
The vaccine will not prevent infection caused by other agents such as hepatitis C and hepatitis E and other pathogens known to infect the liver.
Twinrix Adult is not recommended for postexposure prophylaxis (e.g. needle stick injury).
The vaccine has not been tested in patients with impaired immunity. In haemodialysis patients and persons with an impaired immune system, adequate anti-HAV and anti-HBs antibody titres may not be obtained after the primary immunisation course and such patients may therefore require administration of additional doses of vaccine.
As with all injectable vaccines, appropriate medical treatment and supervision should always be readily available in case of a rare anaphylactic event following the administration of the vaccine.
Twinrix Adult should under no circumstances be administered intravenously.
Effects on Ability to Drive and Use Machines: The vaccine is unlikely to produce an effect on the ability to drive and use machines.
