im on my 2nd lot of HG (had it for 9m last time)
I went to my Dr as soon as my sickness started, and was not allowed them... (she knew my history)
her reasoning was, at that point i still only had MS....
the tablets, while being really quite safe, are still a risk.
She told me she would not prescribe them as the tables are to treat hyperemisis, not to treat MS, and if they were perfectly safe all pg people would get them, which of course they dont.
3 days later i had become hyperemisis and was allowed them.
the tablets they prescribe do not stop me being sick, and do not make me feel better.
The only aim (as told by 3 GPs, and the hospital Drs) are too reduce sickness to the point where you dont dangerously dehydrate... they allow you to keep in some fluids rather than none....
saying that, even on max dose of tablets many many people with HG still vomit so much they need IV rehydration in hospital.
They make HG slightly less severe than it otherwise would be (bear in mind, that with no medical intervention at all HG can kill).... but many many people who get them (including myself) are still sick enough to need to be admitted to hospital, often many times.
The certainly dont make me feel magically better.... i was bedridden for 2 months (with tablets) last time
