I am new to this site and was diagnosed with pmr in June 2017 at aged 61. Having started on 15 mg pregnisolone I am now down to 9 mg but having some backache. This started after I accidently took 21 mg of prednisolone by mistake 3 days ago (took wrong dosage of 5 & 1 mg). The next day I just continued on my normal 9 mg dose having been on that amount for a week. Has anyone made such a mistake with the medication & what was the outcome? I have spoken to a pharmacist but not contacted my GP. Any thoughts would be greatly appreciated.
