What is Bupropion?

Bupropion is an atypical anti-depressant used as a co-prescription drug for the treatment of depression in adults.2 It binds to enzymes responsible for the uptake of dopamine and norepinephrine and thus allows the accumulation of the two neurotransmitters in the synaptic clefts. The upregulation of both dopamine and norepinephrine results in the reduction of depressive symptoms. Unlike other typical anti-depressants, Bupropion lacks the affinity for serotonergic receptors. Therefore, the drug does not cause significant hypotensive, sedative, and gastrointestinal effects 2

It is also used:

– To treat seasonal affective disorder (SAD) 1

– As an adjunct for smoking cessation

– As a co-prescription drug with naltrexone for weight loss

– In combination with other anti-depressants for treatment-resistant depression

– Attention deficit hyperactivity disorder (ADHD) 1


How to use Bupropion?

The medication is available as a tablet with different dosages. Your doctor will prescribe you a dosage as per your condition, age, and medical history. When prescribed, the tablet is taken orally with water. It could be taken without food. In case of stomach upset, take it with food. Swallow the tablet without breaking or crushing it.

It is imperative to follow the doctor’s direction. Put a reminder to help you follow your dosage schedule. Stopping drug intake without a doctor’s approval will have serious side effects like seizures and worsening of your condition. It will take 2-3 weeks before you can see an improvement in your symptoms.1 You can avoid sleep problems by taking the tablet earlier and not at bedtime.
