Prior to the infamous lawsuit, coffee cups at McDonald's did not warn that the coffee is hot; does the fact that this warning was not on the coffee cups mean that the coffee is cold?
And because a package doesn't list every conceivable side effect does not mean that it can't happen. Many people have a very cavalier attitude regarding over the counter (OTC)medications. I have seen patients end up on kidney dialysis because they took too much ibuprofen for their back pain. There is a REASON that drug packaging has warnings. Benadryl packaging clearly warns "CHILDREN UNDER 6 YEARS OF AGE CONSULT A DOCTOR". After seeing this story, people will now know why this warning is there.
BTW, it is OK for an infant to use Benadryl in certain situations IF PRESCRIBED BY A DOCTOR.
Yes, it has been prescribed more than once for our one and two year old granddaughters. We meticulously measure out the dosage, and my wife and I double-checked it until we had the routine down. Don't use a spoon; use a graduated dropper. Also, quiz the pharmacist to verify the dosage (avoid metric confusion).
The girls have had no problem tolerating it and it has been effective.
Anyone who can not follow a more-than-usual care procedure in dosing should not be administering it to an infant. I agree with the poster who commented on how potent a sleep inducer Benadryl can be, even for an adult. I myself, 160 lbs. have taken half an adult dose and been knocked out so thoroughly I slept through a cold draft and finally woke up in the morning with the right half of my body barely functional. Be careful.
