Hi Kay

Have you ever had this reaction before?  Have you used anything new...new cosmetics, lotions, soaps?   Eaten any new foods?  Any known allergies?

In researching your question I found others who did suffer an allergic reaction from Wellbutrin which you can find here.

On a site called Counselling Resource they give a pretty clear warning about this: 

"Stop taking WELLBUTRIN SR and contact your doctor or health care professional if you have signs of an allergic reaction such as a skin rash, or difficulty in breathing. It is not possible to predict whether a mild rash will develop into a more serious reaction. Therefore, if you experience a skin rash, hives, fever, swollen lymph glands, painful sores in the mouth or around the eyes, or swelling of lips or tongue, tell a doctor immediately, since these symptoms may be the first signs of a serious reaction."

If I were you I would call your doctor or pharmacist immediately and tell them of this reaction.  If it is caused by the Wellbutrin you don't want it to get worse.  You don't know yet if this is the cause so...please seek the advice of your doctor.

Thank you for your question.
