hi doc , my son is 7 years old , every year during springs he have eye allergy , and every year use to administer him cromal forte. he got the same allergy in the month of November (this is a new place for us due to job) and upto till date he is suffering from same. we consulted a ophthalmologist an d he prescribed one steroid and mast cell stabilizer ( like cromal ) after 1 month every thing became normal . when we visited again to doctor he again advised to continue for one month. but we didnot administered the steroids , but we started cromal twice daily. please let me know how it started in the month of november and cromal is safe and what are the chances of bacterial infection and way of being safe from them.
