Confused

Just returned from Gp, i had a blood test last week to check my theophlinne levels as they were too high when i was last at the brompton so it was reduced from 300mg bd to 225mg bd but now my levels are only 2.2 has anyone else experienced this

How long after your had taken your tablets were the blood tests done?

Also are your GP and the Brompton using the same measuring method. There are different ways of measuring theo levels and you have to make sure you are looking at the comparable results

I had taken the tablets around 5 hours before the blood test, i have emailed Debbie at the brompton hopefully she will be able to adivise me what to do beofore i next see them on the 2nd of april
