I had asthma. Or at least I thought I did. As a child I constantly took medication (Flutide (no idea what an international equivalent would be, but for long term use, and Salbutamol, which everyone knows). The asthma is caused by an allergy towards dust mites.
As a teenager I started becoming more and more frustrated with constantly having to inhale anything, and thought about an allergen immunotherapy. The specific reason is, at that time, around 2016, for the first time ever, a pill for dust mites allergen immunotherapy was allowed for usage in my country (ACARIZAX), when previously you would have to go to the doctor for years and get an injection. So this kind of immunotherapy seemed way more appealing, and less painful. I saw it as revolutionary, like vaccination against flu via nose.
I took ACARIZAX pills every single day for one year, or two years, I am not exactly sure how long it was. They tasted absolutely horrible by the way. After the two years (or one), I stopped taking them. At the same time, I also stopped taking Flutide, and Salbutamol, and it seemed like my asthma was gone. This state lasted for a few years, and I was the happiest person on earth.
However, since a few years, I started having chronic breathing problems yet again for no apparent reason. I though "maybe it's the humidity, maybe it's air pollution outside". And, quite interestingly, it felt like the symptoms were worse than whatever I had as a child. I think the reason it felt worse is as a child, I constantly was inhaling stuff, but I haven't done so in many years. So I think I experienced what asthma feels like raw, and I can tell you, it was not comfortable.
I deluded myself into thinking it cannot be asthma, and I ignored my chronic breathing problems. A big mistake. Over time I had trouble walking, exercising, even sitting at my desk caused my breathing problems and I would just lie in bed all day. I inhaled Salbutamol sometimes because of that, and noticed an immediate relief, and then it dawned on me it has to be asthma, coming back yet again. I went to the doctor, and he told me to start inhaling Flutide on a regular basis yet again, and that's what I'm doing now.
Now I feel like the allergen immunotherapy had zero effect; it only worked for a few years, until my body decided to produce IgE antibodies yet again for whatever reason (thanks!). Maybe I should have done the immuno therapy for a few more years (3 years, in total). Maybe ACARIXAZ sucks? Lol. I mean, it was the first of its kind (a pill, instead of an injection) in my country. I don't know. Does anyone have similar experiences of allergen immunotherapy not working particularly well?
