I tried Daliresp and a couple of other pills the specialist prescribed buy all had side effects. "Mainly diarrhea" among other side effects,

Yes, if you don't have a big chronic bronchitis aspect to your COPD, daliresp isn't appropriate. If you have lots of mucous and difficulty with frequent exacerbations, then it's certainly worth trying. Most of us who have COPD have both chronic bronchitis and emphysema, but one is usually more prevalent than the other.

The NAC is similar to mucinex. It's designed to help get the mucous thinner so you can cough it up and out. Daliresp is a pill that is also designed to reduce inflammation in the lungs, therefore reduce mucous production, therefore reduce exacerbations. Both are designed for people who have significant problems with mucous production.

Yes have emphasemia, but COPD more promoninent, always have predisone at home plus antibiotics,

Let's put meds in perspective. The FDA rules say that pharma companies have to include everyuthing that happened to anyone in their clinical trials, whether or not the med they were taking had anything to do with it or not. They are not required to follow-up with causality studies for everything that happened to everyone, so as you look at that list, remember that some of those things happened to only a very few people in the trial, maybe only one person. The FDA also knows when they look at a med to approve it how many or what percentage of the people in the trial experienced the more common side effects. That's part of the consideration of whether to approve the med or not.

Every med has side effects, so choosing to take any med is a balancing act: you have to decide for yourself, along with your doc, whether the risk of experiencing any or all of the side effects will be worth the good the med can do. Chemo is a great example. To get the benefit, you have to put up with nausea, the fatigue, maybe losing your hair, etc. Most of us would opt for the chemo for the benefit, but sometimes people don't, and that's fine.

Daliresp is also a good example. Some people don't experience any of the side effects and do very well on it. Some people can take smaller doses in the beginning and work up to the full dose and get over the ide effects. Some people can't tolerate whatever side effects they have and quit. The point is that you never know what will happen until you try it. Remember if you try it and it doesn't work for you or you have some of the side effects and can't manage them, you quit taking it. It's only if you don't try at all that you really lose because you will never know whether it might have been really good for you or not.
