Hi there.
My LB was dignoised with allergies at 10 Months and was put on Adco Zytofen. I did find that it was effective in that my babies noise was'nt running that badly and eased the cough,it also helped him through seasons like september etc. However my LB has quite bad allergies and I found that he still had a constant runny noise on Adco Zytofen. His 18 months now and took him to the GP last month who has prescribed deselex for my LB. His only been on it for over a week now, but definatly see the improvment already.
The meds will just help your LB get through days where the weather causes people with allergies to go bad and will also allow your baby not to be so congested anymore.
