I've been taking Spiriva for the last 7-8 months and it has helped control my asthma. At first I used the delivery mechanism that looks like a little UFO. You put the capsules in and it pierces them. The capsules tend to disintegrate before you get them in the mechanism but this was nothing compared to the problems I've experienced with the one I have now.
My new prescription gave me the one in the attached photo. It took two, reasonably intelligent, adults to work out how to use it. It requires a twisting action and "pat your head while rubbing your tummy" type coordination to operate. I'm a fit (apart form asthma) woman with no arthritis or other mobility problems. I wonder how someone very elderly or weakened by COPD or asthma can deal with this unfriendly mechanism.
I'm never entirely convinced I've had a dose and it makes me cough as it comes out at speed.
It's great that asthma drugs are coming out that help but pharmaceutical companies, please remember that people, often in poor health, have to use them. Makes me nostalgic for my old 1970s Spinhaler.
