Hi there,
I'd love to give you my experience with it. My doctor is the one who created/discovered this Ibuprofen treatment so he tried to get most of his patients on this 15 years ago when it finished studies. I started it in 1994 when I was 13 years old. They say it should be started before age 13 because otherwise it doesn't have much benefit.
At age 13 before the Ibuprofen, I was very low on the weight charts and my FEV1 was pretty stinky. Now, there's not proof that the Ibuprofen did this for me but I really feel that it helped me be as healthy as I am today. I swear by this treatment! My FEV1 is now great and I am actually overweight. This all could've happened with a growth spurt or some other thing (like Tobi), but I really feel that Ibuprofen has played a lot in keeping me healthy.
It is shown to slow the progression of the lung disease by reducing the inflammation. Apparently most CFers lose 3% of their lung function per year, whereas on the Ibuprofen, you lose less than 3%. It also sort of "tricks" your body into thinking your lungs are normal (without inflammation), which can increase your body weight as well. Sometimes people with CF can have lower weights/heights because their lungs cannot sustain a large body. I know a lot has to do with malabsorption too though. I grew a ton after I started the Ibuprofen.
I have since had to come off the Ibuprofen (I stopped it a few months ago) due to me trying to get pregnant. I also had to stop it because it was causing me severe stomach problems. That is the most common side effect from taking large doses of Ibuprofen and that is the reason why most people have to end the treatment. I was experiencing severe reflux and gastritis because of it. So I would say that I had a great 13-year experience with it, but I will not be going back on it after my pregnancy either. My stomach needs to reheal and I believe I was one of the lucky ones who was able to be on it for many years. I had great benefits from it. But that's not the case with everyone.
A lot of doctors disapprove of the treatment and do not encourage it. But I think if it's something you're interested in then you should pursue it. It is a controversial treatment, but some people do VERY well with it.
PM me if you have any other questions.
Good luck to you,
