I was placed on a Patient Controlled Analgesic (PCA) machine
that administered a small dose of Morphine Sulphate whenever I
pressed the button - but no more frequently than once per 5 minutes.
It was extremely effective in controlling pain but I had side
effects which I believe were worth accepting just to control the
pain. I was removed from the PCA about 48 hours after surgery.
The side effects I believe were: MST is Modified Morphine Sulphate BP, SR tablets. I take 2x30mg twice a day and have found it to be wonderful. However, I know that others have had problems on this drug and I have been told that doctors have no way of weaning people off MST. I also take Gabapentin, Fluoxetine, Clonazepam and Zopiclone. Pebbles - a member of RSD_UK Group 18 months ago I read RSD Alert wherein it was logged in was not
possible to reduce MST. I asked my GP if I may reduce the prescribed
does of 25mg am and pm 24/7. He agreed, I am also prescribed Prednisolone,
Lansoprazole and many more. Initially I missed the 5mg decrease
at the 9am drug round but I believe my body and mind have adapted
to it and the muscle problem is due to daily exercise, I am determined
I can walk if I persevere. I become irritable. Some days I am
very tired so I take a nap but have to set an alarm. Val -
York, UK My pain got so bad recently that I turned up at my hospital doctors clinic on the 1st October without an appointment and demanded to be seen!! The doctor has now put me on a drug called MST. This is a slow release morphine sulphate drug and the difference is amazing! My pain level has really dropped. For now, at least, I am not going to completely get rid of the pain - but what a difference! The dose has to be increased gradually in order that I don't overdose, but it really helps. It is a slow process in getting up to a high enough dose to make a real difference, but the signs are all there that this is my lucky break. I am now on 20mg twice daily and am impressed (very hard to believe after 2½ years of bad pain in both legs. Mickey - Isle of Sheppey, Kent, UK I was taking MST 4 x 30mg tabs a day 2 in the morning and 2 at night, but they had little or no effect, so I stopped taking them and all my other meds as well because they just made me into an aggressive zombie and did not help with pain.
