Hello
As you mentioned that you son is a patient of
childhood asthma .
Triggering factors of asthma are , hay , pollen , dust , mite , sudden fall & rise of temperature , fins dusting powder, so if possible try to avoid these.
Usually the cause of
fever in such cases may be due to INFECTION or also due to
allergy .
When such type of patient visit in my clinic ( usually a very common disease )I at once advise my patient to take "monteleukast +bambuterole " combo pack tablet once or twice in day , till complete relief ( very very effective).
Above mentioned dose is only for adults.
Since your son is 6 years ,weight is 20 kg so 1/2 tablet will be sufficient once or twice in day.
If fever occurs then take
levofloxacin 10 mg / kg body weight in a single dose . Once symptoms are in control , stop all medicine , if recurs , start medicine .
Once your child will attain the age 15-16 years these attacks will subside.
Hot coffee also helps in such cases.
Hope this information will help you.
