As stated on the cRc list, there is a pharmacy Lakewood which makes a kosher liquid ibuprofen. There is also a pharmacy in Toronto which makes their own version.
There is no kosher ibuprofen, ADWE only makes acetaminophen (Tylenol). I wish they would make ibuprofen!
Don’t post when you do not know what you are talking about. You can be machshil people with real issurim!!
