I don't post much here any more, but do still read. I'm back with a question: if you stop taking a theophylline based drug (I've been taking Uniphylline), how long is it likely to continue having any positive effect?
I know this is a weird question, but the background is that I am trying (under GP guidance) allergen avoidance strategies. But, rather stupidly, I started taking Uniphylline about three weeks before I started the allergen avoidance (not a very well designed experiment!). I'm as SOB as ever but less wheezy, but of course I dont know if that is due to allergen reduction or uniphylline, so I wondered how long i would need to stop the uniphylline for in order to find out!
