I have pulled my back severely and have been prescribed Baclofen which has no interactions on the leaflet applying to me or my meds. BUT - there are references to palpitations and other more worrying things like lengthened QT in some research papers I have found. Hopefully, these are extremely rare.
As I never take anything without researching first, I wondered if anyone has anything to say about their experiences? Desperate for pain relief and a night's sleep.
