How do I take IVIg and how long does it take to work?

IVIg is given by intravenous infusion (a drip into a vein). You’ll need to go to hospital each time you have the treatment. The infusion will take several hours as the drug has to be given slowly. The rate of the infusion will be increased during the first hour if you have no problems. You’ll be observed closely and have your blood pressure, pulse and temperature checked regularly. After the infusion has finished you’ll need to be observed for an hour to check for any side-effects.

Depending on the condition you have the infusions are given on just one day, or on 2–5 consecutive days. Some people may require repeat courses every 4 weeks. The dose will be calculated according to your body weight.

How long does IVIg take to work?

IVIg doesn’t work straight away. It may take 2–12 weeks to become effective.
