Been on Seretide for 4 years 125mg 1 puff per day just before bed. For 2.5 years I've been suffering with pain just below my left cage on the side of my torso, panic attacks started 2 years ago only to have been really bad earlier this week. I've just come off blood thinner Clexane 60mg for 10 days due to pre blood clot formation in my left leg, although blood results came up normal for anything serious. Also had an infection in the leg which meant antibiotics 875mg amoxicillin every 8 hours for 10 days. In addition to this, I've had serious vertigo and pain in left shoulder, chest and legs. I made the decision to come off Seretide and go on to Becotide and after 3 days I'm feeling a lot better, but unfortunately get the headache assoiated with Becotide, still not happy. I did some research this evening and found information on Cromolyn Sodium on the net which is a non steroid 8-) inhaler. If you Wiki it, you'll see why I mention it here. (It has different shelf names in different countries.) So tomorrow I'm going to the pharmacy to find it. Seretide is just too toxic for me.
