Zyban (bupropion hydrochloride) is a prescription medication specifically developed to support smoking cessation in adults. Unlike nicotine replacement therapies, it functions as a non-nicotine aid that works on brain chemistry to reduce withdrawal symptoms and the urge to smoke. Clinical studies have demonstrated its efficacy when used as part of a comprehensive cessation program that includes behavioral support and motivation. By targeting neurochemical pathways associated with nicotine addiction, Zyban offers a distinct pharmacological approach to breaking the habit.

Common use

Zyban is indicated as an aid to smoking cessation treatment in adults. It is intended for use in patients who are motivated to quit smoking and are participating in a behavioral support program. Treatment should be initiated while the patient is still smoking, with a target quit date set for the end of the first week or beginning of the second week of treatment. It is not recommended for use in individuals under 18 years of age.

Dosage and direction

The recommended dosage for Zyban is 150 mg taken orally 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 typically 7 to 12 weeks; longer treatment may be considered for some patients based on healthcare provider assessment. It is important to follow the prescribed regimen and not exceed the recommended dose.

Precautions

Patients should be monitored for neuropsychiatric symptoms, including changes in behavior, hostility, agitation, depressed mood, and suicidal thoughts or actions. Use with caution in patients with a history of seizure disorder, cranial trauma, or other conditions that may lower seizure threshold. Zyban may increase blood pressure; regular monitoring is advised. Hepatic or renal impairment may require dosage adjustment. Avoid use in patients with eating disorders. Inform your healthcare provider of all medications being taken.

Contraindications

Zyban is contraindicated in patients with a seizure disorder or history of seizures. It should not be used in individuals with a current or prior diagnosis of bulimia or anorexia nervosa due to the increased risk of seizure. Concomitant use with monoamine oxidase inhibitors (MAOIs) is contraindicated; at least 14 days should elapse between discontinuation of an MAOI and initiation of Zyban. Hypersensitivity to bupropion or any component of the formulation is also a contraindication.

Possible side effects

Common side effects may include dry mouth, insomnia, headache, nausea, dizziness, and pharyngitis. Less frequently, patients may experience tremor, rash, sweating, tinnitus, agitation, anxiety, and constipation. Serious side effects can include seizures, severe allergic reactions, hypertension, angle-closure glaucoma, and hepatotoxicity. Neuropsychiatric events such as suicidal ideation, hostility, and depression have been reported. Patients should seek medical attention if severe or persistent side effects occur.

Drug interactions

Zyban has the potential for significant drug interactions. Concomitant use with MAOIs is contraindicated. It may interact with drugs that lower the seizure threshold (e.g., antipsychotics, antidepressants, systemic corticosteroids). Caution is advised with drugs metabolized by CYP2D6 (e.g., certain antidepressants, beta-blockers, antiarrhythmics), as bupropion inhibits this enzyme. Use with other dopaminergic or noradrenergic agents may increase the risk of adverse effects. Alcohol consumption should be minimized or avoided due to increased seizure risk.

Missed dose

If a dose is missed, it should be skipped unless it is almost time for the next scheduled dose. Do not double the dose to make up for a missed one. Taking extra tablets can increase the risk of seizure. Patients should maintain the regular dosing schedule and contact their healthcare provider or pharmacist if unsure about how to proceed after a missed dose.

Overdose

Overdose of Zyban may lead to seizures, hallucinations, loss of consciousness, tachycardia, and/or cardiac arrest. Other symptoms can include nausea, vomiting, and fever. In case of suspected overdose, seek emergency medical attention immediately. Management is supportive and may include airway protection, ECG monitoring, and control of seizures with benzodiazepines. There is no specific antidote for bupropion overdose.

Storage

Store Zyban at room temperature (20°C to 25°C or 68°F to 77°F), in a dry place, away from light and moisture. Keep out of reach of children and pets. Do not use after the expiration date printed on the packaging. Dispose of unused medication properly according to local guidelines or through a drug take-back program.

Reviews

Clinical trials and post-marketing surveillance indicate that Zyban is effective for many patients attempting to quit smoking, with abstinence rates significantly higher than placebo in controlled studies. Patient experiences vary; some report substantial reduction in cravings and successful cessation, while others may not achieve desired outcomes or experience side effects. Adherence to the prescribed regimen and participation in behavioral support are critical factors influencing success. Healthcare providers generally regard it as a valuable option within a multifaceted approach to smoking cessation.
