Buproprion is just the chemical name for the brand name Wellbutrin. Buproprion SR means Substained Released. Indeed the generic could be not working, I've seen this happen in some people. Better check this out with his doctor.
Of course the increased dosage could have some side-effects but you didn't mention since when he switched.
Easiest way to find out is to go back on the name brand and see if there's a difference.
I have been on sr 150 for two months now and just switched to xl 300 as the sr was not doing anything for me. Should I be expecting a change for the better or are they the same?
There are some people that don't find a noticeable difference in the generic when they change from brand name Wellbutrin. There are some people who do NOT get the same results. Body chemistry is just not responsive to the generic in some people. Ask the Doc to order " brand name only' or give you samples and see if it is different. If he does need the Brand name Wellbutrin ,depending on insurance, it may be a lot more expensive. Don't just let this go. It is worth looking into : even if you are," not a doctor".
hi I too have been on Effexor 75. he raised me to 150 now he added I went to the doctor 3 months and when I got back I had been falling a lot more than I used. he put me on wellbutrin 100mg too. I have felt nauseus and my legs cramp and feel achy when I walk for long. I am going to see if he will let me take 1/2 am and a full pm. when I was on them I had no headaches and felt better except for falling. my balance was off and I missed sit some things and spilled stuff. don't know what to do. fall a lot or feel good. I found out the generic meds do not work on me too. my tagamets dont work the same.here was another did not work at all. but my insurance will only pay fr the generic. good luck mandy876
