Read Dr gupta, I was out on neurotic and my asthma started acting up. I went off the high dose to a low dose and I thought my body was handling it. Now I turned up to two 400 of neurotin ,increased to two instead of 4 and my breathing is very labored like I don't have enough air. I can't find anything about neurotic causing breathing problems. I was on 300 a day but I couldn't breath well. So he increased my dose two 400 mg, three times aday.do you or should I say, had any patients might have. I have congestive he's failure and I got these new era and I'm going down hill.
