Zyban (Bupropion) Buyer and Patient Handbook in Singapore
What is Zyban?
Zyban (bupropion) is an oral tablet used to help people quit smoking. It belongs to the class of atypical antidepressants but is marketed for nicotine-dependence. The medication is approved by the U.S. FDA, the European EMA, and Singapore’s Health Sciences Authority (HSA). Zyban is supplied as a 150 mg tablet.
Who Should Use Zyban?
- Adults who are motivated to stop smoking.
- Individuals who have tried nicotine-replacement therapy without success.
- People without a history of seizure disorders or eating-disorder diagnoses.
- Patients who are not currently taking monoamine-oxidase inhibitors (MAOIs).
How Does It Work?
Zyban works by inhibiting the re-uptake of dopamine and norepinephrine, raising their levels in the brain. This reduces nicotine cravings and withdrawal symptoms, similar to how a car’s fuel-efficiency system works better when the engine runs smoother. The drug does not contain nicotine, so it does not produce the same “high.” Abuse potential is low, but it is contraindicated in Seizures.
Why Choose Zyban?
- Generic advantage: Zyban is the brand name; the same molecule is available as a lower-cost generic bupropion, offering the same efficacy.
- Convenient dosing: Only one tablet per day is needed in the maintenance phase.
- Non-nicotine option: Useful for patients who want to avoid nicotine-replacement products.
- Off-label uses such as Depression treatment must be discussed with a qualified health professional.
Dosage, Administration, Lifestyle and Dietary Recommendations
Recommended Dosage
- 150 mg once daily for the first 7 days, then increase to 150 mg twice daily (morning and early afternoon) for the remaining 7-12 weeks.
How to Take
- Swallow the tablet whole with a glass of water.
- Take the first dose in the morning; the second dose should be taken at least 8 hours before bedtime to reduce Insomnia risk.
Missed Dose
- If you miss a dose and it is still morning, take it as soon as you remember.
- If it is close to the next scheduled dose, skip the missed one-do not double-dose.
Overdose
- Call 995 (Singapore’s emergency number) or go to the nearest Emergency Department.
- Symptoms may include rapid heartbeat, seizures, or extreme Agitation.
Special Populations
- Elderly: Start with 150 mg once daily; monitor for insomnia or agitation.
- Renal impairment: Reduce dose to 150 mg once daily if creatinine clearance < 30 mL/min.
- Pregnancy & lactation: Use only if benefits outweigh potential risks; discuss with a healthcare professional.
Lifestyle & Diet
- Avoid grapefruit juice within 2 hours of taking Zyban, as it can increase drug levels.
- Limit alcohol as it may lower seizure threshold.
- Continue to use behavioral support (counselling, quit-lines) for best results.
Precautions and Warnings
- Do not use Zyban if you have a history of seizures, eating disorders, or are withdrawing from alcohol or sedatives.

Reviews
Started on the 150mg dose three weeks ago to help quit smoking. The cravings dipped dramatically, which is huge. But the insomnia is kicking my butt. I wake up at 3 AM every single night, wired. My friend told me I MUST take the pill before 9 AM, even if I usually dose later. Trying that starting tomorrow because I need some sleep. Energy is great, maybe too great.
I've been using Bupropion for over a year now, primarily for SAD and energy. It definitely works better than the SSRIs I tried-no weight gain, which is fantastic. HOWEVER, my blood pressure spiked a bit, and the first month was pure headache torture. Pro-Tip: I split the 150mg dose into 75mg morning and 75mg afternoon (with doctor's approval) and the anxiety jitters disappeared. Just don't eat a spicy lunch or you'll feel the heart rate climb.
Took this for six months. It killed my appetite, which was a nice bonus, and it did lift the fog enough for me to feel productive again. The major downside? Rage. Unexpected bursts of anger over tiny things. It felt like I had zero tolerance for stupid noise or slow drivers. When I stopped, the mood swings faded, but so did the motivation. I might try a lower dose in the future, maybe 75mg, but 150mg made me snappy.
The dry mouth is NO JOKE. I drink water constantly, but my tongue sticks to the roof of my mouth, especially at night. It did stop me from buying cigarettes, though, almost instantly. I tried to drink my usual two cups of strong Kopitiam coffee the first week on Zyban and I felt like I was going to vibrate out of my skin. USER HACK: Avoid high caffeine; switch to green tea until your body adapts. It helps immensely with the starting jitters.
I'm a long-hauler; three years on 150mg XR. It completely changed my focus at work and gave me back my libido, which the Venlafaxine had killed. It's not perfect, though. The first few weeks, I felt slightly manic, and I get these weird "brain shivers" or zaps if I forget a dose for more than 30 hours. It works silently now, but it's definitely a drug you can't abruptly quit. Consistency and hydration are key.
It worked great for lifting the daytime slump, but it also made my chronic tinnitus much, much worse. It's already a risk listed on the leaflet, but I didn't think mine would amplify so quickly. Within two months, I had to stop because the ringing was unbearable, especially trying to sleep. This pill is truly activating, though, so I understand why people use it. Just beware if you already have ear issues.
Been on it off and on for years. The biggest hack I ever found was taking it with a substantial meal-specifically protein and fat, like eggs or some roti prata in the morning. If I take it on an empty stomach, I get light-headed and feel that weird nervousness, almost like low blood sugar. It keeps me stable, predictable energy all day, but you have to respect the timing and the food interactions.
I use this for ADHD-like symptoms rather than quitting smoking. It helped enormously with initiation-I can actually start tasks now. The downside is that I sweat constantly now, even when sitting still, which is awful in this climate. I found that incorporating a small magnesium supplement (Mag Glycinate) at night helps counter the restlessness that sometimes creeps in. Worth the trade-off for the focus, but definitely carry a hand fan.
