About 5 days ago I had my pumps switched over from seretide (as was not working) to Fostair Nexthaler. Although my asthma symptoms have improved, the day after starting Fostair I developed all over body pain, muscle cramps in legs, dizziness and feel generally unwell. The leg cramps have got so bad been taking paracetamol. I'm now on day 5 with the same side effects and they are getting worse. Has anyone else experienced these side effects before? Do they go away when your body gets used to the drug?
Annoying as lung wise it's really helping but not sure I can put up with the side effects.
