Bupropion SR is a sustained-release antidepressant medication designed to help manage the symptoms of major depressive disorder. As a norepinephrine-dopamine reuptake inhibitor (NDRI), it works differently from many other antidepressants, offering an alternative for patients who may not tolerate SSRIs well. This formulation provides steady medication levels throughout the day with twice-daily dosing, supporting consistent symptom control and improved quality of life for those battling depression.

Common use

Bupropion SR is primarily prescribed for the treatment of major depressive disorder in adults. It may also be used off-label for seasonal affective disorder, attention deficit hyperactivity disorder (ADHD), and as an aid for smoking cessation. The medication helps alleviate the core symptoms of depression, including persistent sad or anxious mood, feelings of guilt or worthlessness, loss of interest in hobbies and activities, fatigue, difficulty concentrating, and changes in sleep or appetite patterns.

Dosage and direction

The initial recommended dose is 150mg once daily in the morning. After at least three days, the dose may be increased to 150mg twice daily, with at least 8 hours between doses. The maximum recommended dose is 200mg twice daily. Tablets should be swallowed whole and not crushed, chewed, or divided, as this would破坏 the sustained-release properties. Bupropion SR may be taken with or without food, though consistent administration with food may help minimize potential stomach upset.

Precautions

Patients should inform their healthcare provider about any history of seizures, head trauma, brain tumor, or eating disorders, as these conditions may increase seizure risk. Use caution when driving or operating machinery until response to the medication is known. Regular monitoring of blood pressure is recommended, as bupropion may cause elevation in some patients. Alcohol consumption should be minimized or avoided, as it may increase seizure risk and reduce the effectiveness of treatment. Patients should not abruptly discontinue treatment without medical supervision.

Contraindications

Bupropion SR is contraindicated in patients with a current or prior diagnosis of bulimia or anorexia nervosa due to increased seizure risk. It should not be used by individuals with a known hypersensitivity to bupropion or any component of the formulation. Concurrent use with monoamine oxidase inhibitors (MAOIs) is contraindicated, and a 14-day washout period must be observed when switching between these medications. The medication is also contraindicated in patients undergoing abrupt discontinuation of alcohol or sedatives.

Possible side effects

Common side effects may include dry mouth, nausea, decreased appetite, weight loss, constipation, dizziness, increased sweating, tremor, blurred vision, tinnitus, and insomnia. These often diminish with continued treatment. Less common but more serious side effects may include severe allergic reactions, irregular heartbeat, mood changes, anxiety, panic attacks, trouble sleeping, aggressive behavior, hallucinations, seizures, or symptoms of serotonin syndrome. Patients should contact their healthcare provider immediately if they experience any severe or concerning side effects.

Drug interaction

Bupropion SR may interact with numerous medications including MAO inhibitors, other antidepressants, antipsychotics, beta-blockers, antiarrhythmics, corticosteroids, theophylline, and HIV medications. It may affect the metabolism of drugs metabolized by CYP2D6 enzymes, including some antidepressants, antipsychotics, beta-blockers, and type 1C antiarrhythmics. Concurrent use with other medications that lower seizure threshold should be avoided. Patients should inform their healthcare provider about all prescription and over-the-counter medications, vitamins, and herbal supplements they are taking.

Missed dose

If a dose is missed, it should be taken as soon as remembered unless it is almost time for the next scheduled dose. In that case, the missed dose should be skipped and the regular dosing schedule resumed. Patients should not take double or extra doses to make up for a missed dose. If multiple doses are missed, patients should contact their healthcare provider for guidance on resuming treatment.

Overdose

Symptoms of overdose may include seizures, hallucinations, loss of consciousness, tachycardia, and cardiac arrest. In case of suspected overdose, immediate medical attention should be sought. Emergency treatment may include gastric lavage, administration of activated charcoal, and supportive care including anticonvulsant medications for seizure control. There is no specific antidote for bupropion overdose.

Storage

Store at room temperature between 15-30°C (59-86°F) in a dry place protected from light and moisture. Keep in the original container with the lid tightly closed. Do not store in bathroom cabinets where moisture may accumulate. Keep out of reach of children and pets. Properly dispose of any expired or unused medication according to local regulations.

Reviews

Clinical studies demonstrate bupropion SR’s effectiveness in treating major depressive disorder, with many patients reporting significant improvement in mood and daily functioning. Patients often appreciate the different side effect profile compared to SSRIs, particularly the lower incidence of sexual dysfunction and weight gain. Some users report initial side effects such as insomnia or dry mouth that often diminish over time. Healthcare providers value the sustained-release formulation for its consistent therapeutic effect and convenient twice-daily dosing schedule.
