How long have you been taking Geodon? This is the first I've heard of Geodon causing these symptoms but there is always a first for everything. Are you seeing a GI doctor to be certain it's acid reflux?

Also, I read somewhere where you shouldn't take an antacid two or three hours before or after taking Geodon because the antacid neutralizes the effectiveness of Geodon.

Here is a list of Geodon's possible side effects:

Anxiety, constipation, diarrhea, dizziness, drowsiness, dry mouth, feeling unusually tired or sleepy, headache, increased cough or runny nose, loss of appetite, nausea, restlessness, upset stomach, vomiting, weakness, or weight gain. My Geodon medical insert then goes on to say that if these side effects continue or are bothersome, check with your doctor.
