Another methacholine challenge

Methacholine challenges are not fun at all. They usually take about an hour and consist of breathing in methacholine, which causes a reaction in asthmatics, and seeing what happens. After each dose, spirometry is done to see how the patient’s breathing if faring. If your lung function reduces by 20% or more, you’re asthmatic.

I have now done four of these tests. Two of them have been negative, and two have been positive. Last week, my test was definitely positive. I don’t see my doc for a few weeks, but I assume he’ll agree with the results. Since my previous methacholine challenge last fall, I have been off all asthma maintenance meds. I was also off allergy meds for roughly two weeks this time. While asthma isn’t a preferred diagnosis to have, it definitely uncomplicates things.

Since the test I’ve been able to go back on all my meds, and I’ve started using Dulera again. I’m tracking peakflow numbers during this month and I’m guessing they’ll be trending upward. I think I was overmedicated on asthma meds for a very long time with other things going untreated or under-treated. It would be really awesome if my health could stabilize and I not end up in the hospital this summer.
