prevacid and crohn's

My 8 year old son was recently diagnosed with Crohn's disease.  The dr. wants him to take prevacid, in addition to the pentasa he is taking 3 times a day.
Also--i saw some info on not taking prevacid if you've had allergic reaction to penicillin (which he has)..........anyone know anything about that?
thanks

Hi Sue,
Prevacid is used mainly to protect the stomach from ulcers etc. You probably should be talking to your sons doctor or pharmacist and ask if it is ok that he takes the prevacid when he has an allergy to penicillin. A lot can also depend on the type of reaction he gets from the penicillin as well. So my advice would be just to call up your pharmacist or doctor and ask. It never hurts to be safe rather then sorry. Hope that helps!

My daughter also takes pentasa and WAS taking prevacid.  The prevacid didn't seem to help her and our GI switched her to prilosec.  My daughter has had no complaints with the prilosec.  Both prevacid and prilosec have the same actions so they do the same things.  The only interaction that I know of with prevacid and penicillin is with a type of penicillin called Ampicillin and it may inhibit the absorption of the prevacid.  Good luck, hope this helps
