Bupropion Tablet Side Effects (Nuksanat)
Bupropion Tablet (Wellbutrin / Zyban) has a distinct side effect profile — very different from SSRIs. There is NO sexual dysfunction and NO weight gain — but insomnia and seizure risk are important concerns.
Common Side Effects (Aam Nuksanat)
- Dry mouth — drink more water; sugarless gum can help
- Headache — usually mild; ask doctor about OTC analgesic
- Insomnia / activation — take in the morning, NEVER at night — this is the simplest solution
- Agitation / anxiety — especially at the start; inform doctor
- Tremor — mild; monitor
- Dizziness — exercise caution while driving
- Constipation — increase fibre and water intake
- Nausea — taking with food reduces it
Notable absence: No sexual dysfunction, no weight gain, no sedation.
