Am trying to find out whether rhogam (anti-D) shots given to pregnant women in the UK who are rhesus negative still contain the preservative thimerosal?
A friend of mine who is rh- and pregnant has been told by her midwife that rhogam shots given to UK women do not and have never contained thimerosal.
The midwife has given details of the NHS supplier of rhogam shots as Bio Products Laboratory (www.bpl.co.uk) and the BPL rhogam patient information leaflet says this:
(as well as immunoglobulin) "the product also contains sodium chloride at the same strength as is normally found in your body, glycine to enhance stability and sodium acetate with a small quantity of sodium hydroxide to control acidity/alkalinity during manufacture"
Is it correct that rhogam shots in the UK have never contained thimerosal? If not, has thimerosal in rhogam shots now been phased out? Does anyone know when the phasing out began?
Thanks for that link - some good information in there, although some of it is a little out of date. For example, Bayer no longer make a mercury free Rhogam shot - I rang them up about it and they referred me to Ortho Clinical Diagnostics, based in New Jersey. I havent been able to contact Ortho yet but if I find out any more, I will let you know so you can add it to your info.
Update on anti-D research: I have had it confirmed from 3 sources now that anti-D shots in the UK have never contained thimerosal. One source was a rhesus neg pregnant Mum who did her own research, one source was an independent (non-NHS) midwife and one source was a friend who is a Pharmacist.
The supplier to the NHS at the moment (July 2007) appears to be Bio Products Laboratory and their information leaflet about anti-D shots is located at
