I've read on this site that Wellburtrin does not have sexual effects. I took Prozac for many years and had great success...it is a good med.
If the Paxil is no longer doing the job, you need to let your prescribing doctor know this. Our bodies build up a tolerance to these types of meds and normally we need a dosage change or a completely different medication. I think they all carry the sexual side affect, but I'm not 100% sure of this, but I am sure that someone who is more knowledgeable on this will jump on and better advise you. Take care....
