Red Back Spider Antivenom is given to those people who become ill after being bitten by a red back spider.
Not everyone who is bitten needs the antivenom as some people have only very mild effects from the bite or none at all. However some people can become very ill after being bitten and in these people it is essential to use an appropriate amount of antivenom to counteract the effects of the poison.
Red Back Spider Antivenom is an injection designed to help neutralise the effect of the poison (venom) of the red back spider.
It is made by immunising horses against the venom of the red back spider and then collecting that part of the horse’s blood which neutralises this poison.
The antivenom is purified and made into an injection for people who may need it after being bitten by a red back spider.
Ask your doctor if you have any questions about why this medicine has been given to you.
As there are sometimes unpleasant and dangerous reactions to the antivenom (see Side Effects), it should not be given to people who have no effects from the bite.
However as Red Back Spider Antivenom can be an emergency life-saving product, it should not be withheld from anyone who needs it.
