This year, Rabbi Bess's list of non-chametz products doesn't AFAICT include any kosher-for-Pesach children's analgesic/fever reducer (acetaminophen/paracetamol) (except one that includes also antihistamine). What to do if, chalila, a kid needs some on Pesach? Any ideas (besides suppositories and calling my rabbi)?
Adwe makes a Kosher for Passover children's Acetaminophen. It is available online at http://www.koshervitamins.com/shop/stores_app/Browse_dept_items.asp?showpage=1&Search_Text=1&AZ=Pain+Relief+(Children)&Brand=Adwe+Laboratories
In a pinch, you could crush a 225 mg tylenol tablet and dissolve it in an amount of water that will yield 160mg/5mL, which is the ratio in Children's Tylenol. Of course, CYLMP (call your local medical professional) first!
Tylenol is listed as okay on the cRc list from a few years ago: listed as recommended are:
"Tylenol (All) (Children’s Tablets & Liquid, Children’s Cold Chew Tabs, Infant’s Cold & Fever Reducer), Tylenol (Allergy Sinus, Allergy Cold Medicine No Drow, Flu Nttm hot Medication, Max Strength Flu NightTime, Max Strgth Flu Nttme Liquid, Max Strgth Sinus Nittm, Max Strgth Allergy Sinus Nttme, PM Xtra Strgth, Severe Allergy Caplets, Sinus Medication Maximum Strgth, Multi Symptom Cold Medication)"
That was before the cRc changed their policy to allow all pill medications and not list medicines individually (in what many kashrus professionals I spoke to considered a sharp rebuke to R. Bess) because of the potential danger that by issuing such lists, some people might not take medicine they otherwise should.
So the only question would be whether the formulation changed substantially since 2004?
Triaminic recently started making a liquid acetaminophen. It's recommended in this year's cRc Guide.
