Understanding Wellbutrin Side Effects
Wellbutrin, known clinically as bupropion, affects norepinephrine and dopamine signaling. Common reactions include dry mouth, headache, nausea, constipation, and trouble sleeping. Many people also report mild tremor or a wired, coffee-like energy during the first days. These reactions are usually transient and may soften as your body adapts.
Less common but important effects include anxiety or agitation, increased sweating, and a faster heartbeat. Clinicians describe these as sympathetic activation. Rare but serious events can include seizures and severe allergic reactions. For a comprehensive list and boxed warnings, see the FDA prescribing information for bupropion, which outlines risks and monitoring considerations FDA prescribing information.

XL vs SR: Release Profiles and Fit
Extended-release tablets deliver medicine differently throughout the day. The XL form releases once daily, while SR generally releases twice daily. That difference shapes your experience. Some people prefer smoother coverage with fewer peaks and troughs. Others value flexibility for dose timing. If your schedule is irregular, SR’s split dosing may feel more adaptable.
When comparing options, consider sleep, appetite, headache patterns, and work routines. You might notice fewer afternoon slumps on a once-daily regimen, or better morning activation with divided dosing. To compare package labeling and dosage forms, see Bupropion XL for extended-release details, and Bupropion SR to review twice-daily formulations. If you and your clinician are weighing wellbutrin xl vs sr, highlight your sleep and work patterns to guide the decision.

Some experience a tingling sensation (paresthesia) or a thumping heartbeat when anxious. These reactions are typically temporary. Gentle hydration, small snacks, and earlier dosing may help reduce discomfort. According to consumer drug references, these reactions tend to be mild and often improve as you continue therapy MedlinePlus drug information.

Sexual, Heart, and Nerve-Related Effects
