When did Wellbutrin go off-patent?

Can I switch from brand-name Wellbutrin to a generic?
Patients considering switching from Wellbutrin to a generic equivalent should consult their healthcare provider. While generic medications are designed to be bioequivalent to their brand-name counterparts, individual responses can vary [6]. Doctors can help determine the appropriate generic formulation and dosage.
How do generic Wellbutrin prices compare?
Generic medications are generally less expensive than their brand-name counterparts due to reduced research and development costs for the manufacturers [2]. This can make treatment more affordable for patients.
