About Nigel Simmons
Expertise
I am happy to answer general questions on medicines and hospital care. If possible, please use approved / chemical names rather than brands which are not internationally recognised. Like all health professionals I am bound by a duty of care which prevents me giving detailed information about medication or treatment of people other than the questioner. I will endeavour to help wherever possible or point towards more appropriate advice. If however your question crosses too far into patient confidentiality, I hope you will understand why I cannot answer your question. Consider.. would you want me to discuss your care with a friend or relative without your knowledge?

Experience
Registered as a UK pharmacist in 1982 and have worked in a number of hospital and health management posts around the UK. Formerly Chief Pharmacist for a 440 bed general hospital in Cambridgeshire.
Past/Present clients
Previously Sysop on CompuServe UK Professionals forum.

I'm sure Google and some considered search terms will lead you to more detail.

I hope this helps.
