You should see a pediatric Pulmonologist.
And because your current Pediatrician does not know what to do.
No one, can tell you exactly, what to do or how or when or per your son's, condition.
I have Asthma, since childhood.
I also have seasonal allergies.
But, per MY conditions, what I take and when and how much and per what season, is based on MY, condition. Even if I also, have Asthma and allergies like your son.
EACH person, reacts to, each medication differently. And what I use may not be a "fit" for your son and visa versa.
There are various, asthma medications. They are not all the same.
And each person is different.
My Mom who has asthma, per HER medications and frequency of taking it, is DIFFERENT, than me. And visa versa. So whatever her Doctor tells her per HER Asthma, is not the same, as me or my Doctor.
And, our triggers for our Asthma, is different. As well.
Flovent is a steroidal based medication.
Albuterol is not.
They both do different things and are used for different purposes.
So you need to know that.
I have never... "tapered" off of my Asthma medications. Per MY inhalers, there is no tapering off of it. I simply use it, when I need to, or as a preventative, in order to prevent or lessen extreme asthmatic symptoms. And/or, during colds.
I too, get WORSE with my Asthma, when/if I am sick. But my Asthma is not exclusive to it being only triggered by colds. I know, that.
I also take other allergy meds, as needed or IF needed.
What works for me, may not work for others or their conditions. My Mom takes Zyrtec. I hate Zyrtec, it does not work for me. I take Claritin. My Mom does not because that does not work for her.
And per any steroidal based medications... I don't have to take that... unless, my conditions has reached an extreme level already. But I don't take Flovent. Never have. I had other types of steroidal based medicine, per my Doctor and per my, conditions. If/when necessary.
So you see, what a person takes per medications, will vary, and per their conditions even if others may have the same conditions as your son.
There are a variety of inhalers/albuterol/asthma medications or allergy medications. And any combination of it, varies. Per each person.
Asthma and its triggers, vary per person.
And the management of it and the medications taken for it, will vary.
My Asthma, is not "seasonal" based.
I have never heard of it being seasonal based or using asthma medication according to the season.
I mean, a person can get sick and/or exacerbate their Asthma condition, any time during the year.
But, per "trial and error" process to handle your son's Asthma... that means, getting to KNOW... your son's Asthma condition, its triggers, and knowing WHEN.... you need to start using his asthma medicines as a preventative measure... when/if he gets sick and using it BEFORE it gets.... into a worsening sickness.
With Asthma, it can get really bad, really quick. So for example, whenever I get sick or SUSPECT... I am getting a cold.... I USE my Asthma medications already, as a preventative in order to prevent my getting a full blown asthma, attack. But I KNOW MY BODY... and its symptoms. So then, I can and do use my medications, when I KNOW I need to. But again, each person is different.
Your son is young to realize those things yet. So YOU... must learn that... so that you will know, WHEN to start having him take his asthma medicines.
Asthma medications are either preventative, as maintenance, or as an emergency situation already when it has reached acute... status.
And when that has happened with me, for example, i was put on corticosteroids.
So you also need to learn about the stages of Asthma can occur. By observing your son and asking him questions etc.
Also, the medication combinations that a person takes, (ie: your son takes Flovent and Albuterol and Singulair), can vary. It is not the exact SAME medication combinations, for everyone.
That is not the med combination I take, for example.
My meds are different.
