I have recently been diagnosed with underlying asthma, having developed breathing issues during lockdown. I have been prescribed Fostair 100/6 and have tried both the inhaler and NEXThaler options, both of which evoke side effects of hoarseness, dry mouth ulcers and mucus overproduction. Of the two, the inhaler with spacer tends to provide most effective relief of my symptoms although the NEXThaler is more convenient.
I would welcome comments from other users in relation to my experience thus far in terms of the products and side effects.
