Zyban (bupropion hydrochloride) is a prescription medication specifically developed to support adults in their journey to quit smoking. Unlike nicotine replacement therapies, it works by affecting neurotransmitters in the brain associated with nicotine craving and withdrawal. By reducing the urge to smoke and alleviating withdrawal symptoms, Zyban offers a non-nicotine pharmacological approach to smoking cessation. It is an effective tool when used as part of a comprehensive quit plan that includes behavioral support and motivation.

Common use
Zyban is indicated as an aid to smoking cessation treatment in adults. It is intended for use in conjunction with behavioral interventions, counseling, or support programs designed to help individuals quit smoking. Treatment should be initiated while the patient is still smoking, with a target quit date set typically during the second week of therapy. It is not recommended for use in individuals under 18 years of age.
Dosage and direction
The recommended dosage for Zyban is 150 mg once daily for the first 3 days, followed by an increase to 150 mg twice daily. Doses should be taken at least 8 hours apart to minimize the risk of insomnia. Tablets should be swallowed whole and not crushed, chewed, or divided. Treatment duration is usually 7 to 12 weeks; depending on progress, some patients may benefit from longer treatment under medical guidance. It is important to follow the prescribed schedule and not exceed the recommended dose.
Precautions
Patients should be monitored for changes in behavior, hostility, agitation, depressed mood, and emergence of suicidal thoughts or behavior. Use with caution in patients with a history of seizure disorder, cranial trauma, or conditions that lower seizure threshold. Zyban may increase blood pressure; regular monitoring is advised. It should be used cautiously in patients with hepatic or renal impairment, with dosage adjustment potentially necessary. Alcohol consumption should be minimized or avoided due to increased seizure risk.
Contraindications
Zyban is contraindicated in patients with a current or prior diagnosis of bulimia or anorexia nervosa due to a higher incidence of seizures in such patients. It must not be used in individuals undergoing abrupt discontinuation of alcohol or sedatives (including benzodiazepines). Concomitant use with monoamine oxidase inhibitors (MAOIs) is contraindicated; at least 14 days should elapse between discontinuation of an MAOI and initiation of Zyban. It is also contraindicated in patients who have shown hypersensitivity to bupropion or any component of the formulation.
Possible side effect
Common side effects may include dry mouth, insomnia, headache, nausea, dizziness, and pharyngitis. Less frequently, agitation, anxiety, tremor, sweating, tinnitus, rash, and taste perversion may occur. There is a risk of serious side effects such as seizures (dose-related), hypertension, severe allergic reactions, angioedema, and neuropsychiatric symptoms including suicidal ideation. Any unusual or severe symptoms should be reported to a healthcare provider immediately.
Drug interaction
Zyban has the potential for significant drug interactions. It should not be combined with other medications containing bupropion. Concomitant use with MAOIs is contraindicated. Caution is advised with drugs that lower seizure threshold (e.g., antipsychotics, antidepressants, systemic corticosteroids). It may interact with drugs metabolized by CYP2D6 (e.g., some antidepressants, beta-blockers, antipsychotics), potentially increasing their levels. Use with caution alongside levodopa and amantadine. Inform your physician of all prescription, over-the-counter, and herbal products you are taking.
Missed dose
If a dose is missed, it should be skipped and the regular dosing schedule resumed. Do not double the dose to make up for a missed one, as this increases the risk of seizure. If unsure, contact a healthcare provider for guidance.
Overdose
Overdose may lead to seizures, hallucinations, loss of consciousness, tachycardia, and/or cardiac arrest. Symptoms can also include nausea, vomiting, and fever. In case of suspected overdose, seek emergency medical attention immediately. Treatment is symptomatic and supportive; ensure airway protection and monitor cardiac and vital signs.
Storage
Store at room temperature, 20°–25°C (68°–77°F), in a tightly closed container. Protect from light, moisture, and excessive heat. Keep out of reach of children and pets. Do not use after the expiration date printed on the packaging.

Reviews
Clinical studies and patient reports indicate that Zyban, when used as directed and with adequate support, can significantly improve quit rates compared to placebo. Many users report reduced cravings and easier management of withdrawal symptoms. However, experiences with side effects vary, and success often depends on commitment to a comprehensive quit plan. Discuss with your doctor whether Zyban is an appropriate option for your smoking cessation goals.
