Benadryl is for allergic reactions to a strong allergin. Hives, swelling, etc. It should not be used for just a runny nose and stuff. It dries their sinus' out, they get super glue snot stuck in their sinus' and throat. It is not the best thing for them to take. It may stop the runny nose but think about where it is storing that snot and what is happening to it. It will sit in the sinus cavity and start building an infection. It needs to get out, it's job is to wash away irritants. The super glue goo will find a way out, it may try the ear canal, get stuck and cause an ear infection, may try the sinus drainage route, get thick, green, and make a powerful headache. It may also try to get out through the eyes and cause mucky eyes and redness that looks like pink eye but is really only sinus drainage that is trying to get out.

Take the kiddo to and ORL/ENT doc and get the recommendations from the horses mouth.

From my ped's website:
Benadryl (Diphenhydramine)
For relief of nighttime cough and nasal congestion.
Poison Control Center can be reached at 1-800-222-1222

Since this is the only OTC medication that we recommend, we thought we should have the dosing here. Remember this is plain diphenhydramine (click here for sample pictures) not Benadryl Sinus or Benadryl whatever. As long diphenhydramine (it's sometimes written as diphenhydramine hydrochloride) is the only active ingredient, any version of it, including the store generic brands, is fine.

we had to give some to our daughter because she had a sinus infection and we were flying home in two days. They told us that it would help the swelling in her sinus cavity and ear canals. Who knew? Anyway the pharmacist told us the correct dosage, if you pick some up stop my the pharmacy counter and they can help.

The reason it's not on the bottle is because you are supposed to call your pediatrician and ask. They'll be able to let you know easily. And they'll be able to tell you if Benadryl is what you need or if something else might work better.

It depends on what you are trying to accomplish. I assume you are not trying to stop an allergic reaction since you wouldn't have time to be asking if that were the case.

I know you can use Benadryl with a 2 year old but would think it best to ask your pediatrician what dose is best for your little one.

That would be none, I believe.

Call your pediatrician to make sure.

NEVER guess.

Check Micromedex- a drug info website. If you have an iPhone, they have an app that's free. It's great- I use it all the time whenever I need dosage info. Also, try Dr. Sears website- I seem to remember there being a feature on there that had dosage info for all types of different medications.



answers from Minneapolis on

New guidelines are that kids that young shouldn't take these types of drugs at all (apparently in some cases not safe and sometimes don't work in the very young), unless under the supervision of a physician. If you google the topic you'll find plenty of articles etc. about why the new guidelines have been set.

However, if you have an older pediatric medical book (pre-2005), the old guidelines for dosages are listed for most of the more commonly used over the counter allergy and cold meds.



answers from Pittsburgh on

Current recommendations are not to use at all for colds (it doesn't work) and to avoid for all indications for children under 4.



answers from Dallas on

my pediatrician said 1/4 teaspoon. she's recently advised him (2.5 yrs) to take claritin 1 teaspoon every night. just what we're doing... :)



answers from Boston on

Ugh....benedryl is safe to give my youngest started taking it for hives at 6 months old but it does not last long and should be dosed by weight so call and ask your pediatrician.
If this is for seasonal allergies you want zyrtec or claritin (again these are safe for toddlers nd should be dosed by weight by your pediatrician) they take about a week to reach their full effectiveness.

It is cold medication that you should not give to children under 4.



answers from Detroit on

Call your PED or a Pharmacist. I would not rely on information posted here on something as important of dosage of medicine. While well meaning and most likely correct, you just never know. Good luck!
