Bupropion 150mg is a prescription medication primarily used to treat major depressive disorder (MDD), seasonal affective disorder (SAD), and to assist with smoking cessation. Commonly known by the brand name Wellbutrin, it functions as a norepinephrine-dopamine reuptake inhibitor (NDRI), which works by increasing the levels of mood-regulating chemicals in the brain.
Understanding the Formulations
The medication exists in three distinct chemical releases, each formulated to be taken differently according to specific prescribing instructions:
-
Extended-Release (XL): Formulated for once-daily administration, typically in the morning. This formulation is commonly utilized as an initial option for major depressive disorder and seasonal affective disorder.
-
Sustained-Release (SR): Formulated for administration on a scheduled basis throughout the day, maintaining appropriate spacing between administrations. It is frequently utilized in protocols intended to assist with smoking cessation.
-
Immediate-Release (IR): Formulated for multiple daily administrations with appropriate intervals between intakes.
Common Side Effects
Many side effects are mild and tend to fade within a few weeks of starting the medication. They include:
- Dry mouth and sore throat
- Trouble sleeping (insomnia) or restlessness—taking the medication early in the day can help mitigate this
- Headaches and dizziness
- Nausea, constipation, or mild stomach discomfort
Unlike many other common antidepressants, bupropion is distinct because it rarely causes sexual side effects or weight gain.
Important Safety Warnings
-
Seizure Risk: Bupropion can lower the seizure threshold. It is strictly contraindicated for anyone with a history of epilepsy, seizures, or eating disorders like anorexia or bulimia, as electrolyte imbalances drastically increase seizure risks.
-
Alcohol Interactions: You should limit or completely avoid alcohol while taking bupropion, as mixing the two can increase the risk of neuropsychiatric side effects or seizures.
-
Do Not Crush: Tablets must be swallowed whole. Crushing, chewing, or breaking modified-release pills compromises the release mechanism and increases adverse risks.
