I WAS TAKING GABAPENTIN FOR 9 MONTHS. MY TONGUE WAS SLOWLY LOOKING HIVELIKE. I AM ALSO ALLERGIC TO LYIRCA. I LOOKED UP A LOT OF SYMPTIONS OF NEURONTON ON MY PC AND I FOUND OUT THAT LYIRCA AND GABAPENTIN ARE RELATED. I WENT TO THE ER AND I WAS PUT ON 50mg. OF PREDNESONE. IS THIS AN ALLERGY?
HI, thanks for using Chat Doctor Gabapentin and lyrics are both used to treat similar conditions. It is possible to have an allergic reaction to any Chat Doctor.  The allergic response can be immediate or occur after taking the medication for a prolonged period. Normally there would a widespread rash however, since the rash or change is confined to the tongue only then it is less likely an allergy. It may be best to speak to your doctor about your concerns. I hope this helps
