I have been prescribed Co Proxamol for several years after suffereing a sponataneous pneumothorax in 1996,I found it to be pretty much useless.It makes me feel nauseous almost immediately after taking it.I am of no firm opinion as to whether it should be withdrawn really as I can manage perfectly well without it.However my sister swears by it,she has used it for a long time for severe back injury pain and is livid that it will no longer be available.I have recently been prescribed co-codamol 30/500 for chest pain after lung surgery last April and it works much better,the only side effects I have is being slightly spaced out and light headed and occasional palpitations.My pain is completely under control though so I will continue to take it until my pain resolves itself or an alternative pain killer is prescribed.
