My psychiatrist switched me from Wellbutrin 300mg sustained release to Wellbutrin 150mg extended release, accidentally. I was on the dose for 28 days before returning to her reporting increased anxiety and depression and extreme fatigue. She has now corrected the medication error and I've been on 300mg extended release for 3 days. How soon before I should start to feel better?
Hi, concerned! Normally it takes about 4-6 weeks for Wellbutrin to become effective, but since you've been on the 150mg you should see improvement much sooner. Improvement in the first two weeks usually indicates that the medication is getting close to therapeutic levels again.
Sorry that you had to go through this... but I guess mistakes do happen and it's a good idea to always check your meds for any errors. I had this happen to me once too!
Best regards and I hope you're better quickly.
