I was very recently prescribed Wellbutrin XL, after trying several medications that have not helped [including Wellbutrin SR]. When I saw my doctor, she simply said 'I'm putting you on Wellbutrin twice daily' and I assumed it would be the SR. But what I was given was XL, with the instructions to take it twice a day [morning and around noon]. My doctor's office is closed today, or I would have asked her. I did ask the pharmacist, and he said that yes, this is okay. I don't understand it, and I'm just curious about whether or not anyone else has ever been prescribed the XL in this way. The dosage is 150mg per pill.
