Mood changes on Wellbutrin: what to expect
Mood changes — anxiety, low mood, irritability, emotional blunting — are an under-recognised but important side-effect category for many medications. Whether Wellbutrin (Bupropion) at 75mg, 100mg, 150mg, 300mg causes mood changes depends on Bupropion and the indication. This page focuses on the practical pattern, what is normal and what calls for review.
Documented mood effects of Wellbutrin
For some medications in Anti-Depressants, mood changes are part of the central indication. For others, mood changes are listed in the prescribing information for Bupropion as side effects in a small subset of users, sometimes appearing in the first weeks of therapy and resolving spontaneously. Wellbutrin inhibits the reuptake of norepinephrine and dopamine, with much weaker effect on serotonin.
When mood changes need review
Mild irritability or transient low mood in the first weeks on Wellbutrin at 75mg, 100mg, 150mg, 300mg is common and often improves. Persistent low mood, new anxiety that interferes with daily life, suicidal thoughts, or any sudden severe mood change warrants prompt review with the prescriber. According to current guidelines, suicidal ideation while starting any new medication should be treated as urgent.
