Hi Tara83, welcome to the sight. I find it so helpful and like you, I had no idea so many women with Cf were having babies...LOVE IT!! Ok...rubyroselee...I was not on ibuprofen "treatment", but I did take about 800mg on average twice a day for my sinus headaches for years!! Like you, if I didn't take it I was miserable!! So, I stopped cold turkey and switched to Tylenol rapid release. It took about a week for my body to respond to the Tylenol, but eventually it did. In the past, tylenol nver worked for me. My lung function decreased a little during pregnancy, but they expected that from all the hormonal changes and eventually the baby pushing up on my lungs. After I had him, my PFT's went way back up and right now is the first time in 4 months that I've been sick, so that is good! My Cf doc told me some women do great (even better) after having a baby, and others go down hill fast. Looks like I'm doing better!! I never had any side effects from all the ibuprofen (not yet anyway!), and once I had my son, I went right back on it, but not as much. Now I only take 600mg once if day if I absolutely need it. It is safe to take while breastfeeding. Hope that helps. Feel free to PM me with any further questions.
