I get that too Jas. I can't take anything with codeine, it makes me loopy. If you're still in a lot of pain or you ever get tooth pain again; try taking 4 advil or any generic ibuprofen. That is the presciption strength (800mg). The dentist suggested this to my husband one time and it worked very well on his severe toothache.

Unfortunately, it is quite common to feel like this after taking any meds with codeine in. Stop taking it and try something else.

If it makes you feel like that, it does not mean that you are allergic to it at all. It is normal for lots of people to have that spaced out feeling.
