Ibuprofen is a non-steroidal antiinflammatory drug (analgesic
) that tends to cause gastritis
and altered blood in stool
. To prevent this, to need to take it after food or with a gastroprotective agent like rantidine or pantoprazole
(several like these PPIs are available) and prevent this side effect especially when you need it for a while.
I am unsure what yellow stick stuff you are referring to (and also unsure of your age) but with the tummy aches and headaches and altered GI (gastrointestinal) symptoms, please get yourself seen by a Gatsroenetrologist and tell the entire story. Using PPIs at this time will help so will antihistamines (allegra 180mg or cetirizine
10mg) with your allergies.
