So my older son has become old enough and heavy enough to take 12.5 mg of 100mg/5ml child ibuprofen liquid. Which is all well and good, but kid ibuprofen liquid and the chewable tablets are kind of expensive relative to the adult stuff.

So it occurred to me that a regular old grownup ibuprofen tablet is 200 mg, which is a little less than the full 12.5 mg dose, but we already have those laying around, and for most things like growing pains or mild headaches, are probably adequate anyway.

Is there any real reason we can’t just give him one ibuprofen tablet instead of the kid liquid, since the dosage is actually less on the tablet?

I just realized this weekend that regular strength Tylenol has dosage instructions for kids 6-12, but extra strength (the kind I usually buy) does not. I was giving my son a dose of kid’s tylenol equivalent to one regular strength pill, and paying 5x the price for the grape flavor he hates.

There are ibuprofen dosage charts online that include dosages for kids \<100lbs.

I’m guessing you meant to write 12.5 **mL** instead of 12.5 mg in the above post.

Yeah, I did. Basically it’s 100 mg per teaspoon (5 ml). He gets 2.5 teaspoons worth(12.5 ml), and a tablet is 200 mg. So I’d be short-changing him by 50 mg or a half-teaspoon for the sake of convenience.

Which is still a lot larger dosage by weight than I end up with taking two of the things.

There can certainly be differences other than dosage between a liquid and a pill. How the active ingredient is delivered will affect how quickly it’s absorbed, and where in the body, which can be very significant. How is this relevant to the difference between an adult and a child? Ask a pediatric pharmacologist.

Obvious question - is your son old enough to take a tablet? I mean, that’s the reason (one of them) that there are liquid formulations for kids. There may be a non-zero choking risk that you have to take into account here.

Yeah, he’s 7 and a half. I’m sure he can handle a pill.

We switched our kids from kid-intended liquids to tablets sold for adults as soon as the kids were old enough to swallow a tablet. This was for prescription medication, and when we asked the pediatrician if we could give them tablets he said. “so long as they can swallow them, sure.” He wrote the prescription for pills, and asked us to get back to him for a liquid if they had any trouble with the pills.

Pills are way easier. No fussy measuring, no refrigeration needed, and you can swallow them without tasting the medicine. All the liquids taste nasty under the sweet fake fruit flavors.

If they are both immediate release forms of the medication, then the only difference is the form it comes in. 10 mL of the regular liquid Ibuprofen (100mg/5mL) is the same as 2 chewable tablets, is the same as 1 adult tablet, they are all 200mg. This will be the same for most immediate release forms of most medications. If the dose is appropriate, there is nothing stopping an adult from taking the children liquid, or a child taking a tablet. Just make sure you give the appropriate dose, dosed by the child’s body weight.

For certain extended release formulations, this might not be true. Double check with a pharmacist if you’re giving an adult extended release medication to a child under 12 to make sure it is appropriate.

Yea, that is what I thought when I tried to give my 7 year old a pill. 15 minutes and many tears later, I surrendered.

My kids switched to pills about age 3. And we were all happier for it.

In the ER we choose liquid or pills solely on their ability to swallow pills.

Don’t use an ibuprofen tablet to find out if your kid can swallow pills. Use Tic Tacs, or some other small candy.

Ideal for this are mini baking M&M’s.

I used the tiny cake decor sprinkles for my kids to practice swallowing pills. The fun shapes–flowers, crowns, fish–made it fun, and I wasn’t tempted to eat up the “practice pills.”🙂
