I have not had any side effects from these. I find the caplets very easy to swallow and work quickly They were originally given to me for lower back pain, but have more recently been a life saver for me on arthritis in the knee and the pain following keyhole knee surgery. Some people have problems with the codeine in these as it can cause constipation. I drink a fair amount of water and eat fruit regularly which may help with this aspect.
Took as pain killer following full knee replacment, worked well during day, though did have stronger pain killer for first few nights to help with sleeping, after poss 4 nights went back to the Solpadol. Worked well for me, was prescribed by my Doctor.
Took over a period of two years I was working whilst taking this medication. Became addictive and made me feel hyper in the mornings I think . Because the pain had diminished I was probably aggravating my shoulder neck problem and unaware of two prolapsed discs in my neck. Very difficult to stop taking. Do not take it now but still in pain all the time.
I have been on this medication for some time in respect of a hip replacement that I have had and the other to be done. I find that in does not stop all the pain and sometimes think its not doing anything and do not take a dose. Then you know that it does work as you feel the full depth of the pain. The only downside is it can cause constipation from time to time.
