HI,
Welcome to Health Care Magic
Please do not panic. To be precise no drug is with out side effects. But the benefits should always outweigh the risks.
As far as
montek lc is considered. It has few side effects. These side effects due to montek lc are rarely serious.
Montek lc kid is approved for usage in children for long term of use. The common side effects would be dryness of mouth,
sore throat and occasional irritability. These are often episodic and self limiting. The only definitive treatment for
allergy is avoidance of allergen.
Your son case surely continue this till teen age or even further. He is going to be absolutely fine and the drug shall not give him much trouble.
Giving ventilatory support to lungs is required only in severe cases. Usually you never know when allergy comes and when it disappears.
But children with allergen often tend to recover from the problem during their teenage. Hope your son falls in this category and would be just fine
Wish your son all the very best of health
Take care
