Gp presribed fexofenadine hcl 120mg for my 6yr old girl who suffers from urticoria, the inserts says not tested on kids below 12 yrs, is this safe?

Yes: This is one of the most widely used antihistamines in the us. It is available over the counter here due to its safety profile. It is also used as young as 6 mo years of age for treatment of urticaria.The recomended initial dosage is 30 mg twice daily at 6 years of age.

URTICARIA: A lot of time we prescribe meds, many of them are life saving, but package insert says, "not tested in children, check with your doctor", etc. The reason is, these drugs were tested in adult volunteers only during clinical trial , children volunteers were not available. Like, most risky new drugs are tested on animals initially, not in humans. Fexofenadine can be used for a child as young as 6 mo.

Dr Mumneh and another doctor agreed
