Patient Reviews: How Zyban Has Made a Difference

What Is Zyban?

Zyban is a smoking cessation treatment from GlaxoSmithKline (GSK).

Zyban, scientifically known as bupropion hydrochloride, is a medicine prescribed to aid smoking cessation, especially when combined with motivational support such as a 'stop smoking' programme.

Developed initially as an antidepressant, Zyban's effectiveness in smoking cessation was discovered by chance, leading to its approval for this use.

Unlike traditional nicotine replacement therapies, Zyban works on the brain's neurotransmitters, offering an alternative pathway for those struggling to quit smoking.

Zyban is available to order from Prescription Doctor's online pharmacy.


What is Zyban Used For?

Primarily, Zyban is used to help individuals quit smoking, distinguishing itself from nicotine replacement therapy by its unique action on brain chemistry.

It may also have off-label uses, but it's crucial to consult a healthcare provider before considering such uses. Zyban has demonstrated a notable success rate in helping smokers quit, with various studies showcasing its efficacy.


How Does Zyban Work?

Zyban works by influencing neurotransmitters in the brain, particularly dopamine and norepinephrine. This action helps reduce the intensity of nicotine cravings and withdrawal symptoms, making the quitting process more manageable.

This mechanism is distinct from other smoking cessation aids, which often focus on delivering nicotine in controlled doses to wean smokers off their addiction. More information can be found on the NHS website.


Is Zyban Effective?

Numerous studies have shown that Zyban is effective at helping people quit smoking.

According to, Zyban helps 1 in 5 people quit the habit.


How Long Does Zyban Take To Work?

The effects of Zyban on smoking habits can generally be observed within a few weeks of starting the treatment. Consistent adherence to the prescribed treatment schedule is crucial for effectiveness.

It takes about one week of taking Zyban for the drug to stabilise in the blood. You should be able to stop smoking after taking Zyban for seven weeks and come off the medication after nine weeks.

Factors like lifestyle choices and concurrent therapies can influence the outcomes of Zyban treatment.


Zyban Dosage Directions

The standard dosing of Zyban typically begins with an initial dose, followed by a maintenance phase. Dosage adjustments might be necessary based on individual responses and medical advice.

It is vital to follow the healthcare provider's prescription accurately. Additional details can be found at the NHS Inform.


Who Can Use Zyban?

Zyban is suitable for adult smokers who meet certain criteria based on age, health status, and smoking history. Healthcare providers may recommend Zyban in specific scenarios, considering the individual's overall health and smoking habits.

Its use in diverse populations needs careful consideration, factoring in various health indicators and potential risks. More insights can be gained from the NIH study.


Who Should Not Use Zyban?

Individuals with certain health conditions or on specific medications should avoid Zyban. This includes those with a history of seizures or eating disorders. Full disclosure of health information to healthcare providers is essential for safe use of Zyban.

Alternative treatment: For those for whom Zyban is not suitable, a new treatment under the name of Cytisine has recently been approved in the UK as a prescription-only medicine for stopping smoking. It is a safe and effective treatment and works by acting on the part of the brain that urges you to smoke.

How Much Zyban Should be Used?

Dose adjustments may be required for different individuals, considering factors like age and health conditions. Overdosing on Zyban can lead to serious risks, and it's important not to stop the medication abruptly without consulting a doctor.

Is Zyban Safe?

While studies have shown that Zyban is safe and effective, it is not suitable for everyone.

Our online doctors can determine whether Zyban is the right quit smoking treatment for you following an online consultation.

Do not take Zyban if you:

  • are allergic to Zyban or any of its ingredients
  • are taking other medicines that contain bupropion or naltrexone (such as Mysimba)
  • have a condition that causes fits, convulsions or seizures (such as epilepsy)
  • have an eating disorder (bulimia or anorexia)
  • have severe liver problems (cirrhosis of the liver)
  • are pregnant or breastfeeding

  • are a heavy drinker

What are Zyban Side Effects?

Zyban can cause both common and rare side effects. While many side effects are manageable at home, some require immediate medical attention. It's important for users to be aware of these potential side effects and to seek medical advice if they experience any severe or concerning symptoms.

Side effects of Zyban may include:

  • Mood changes (depression, anxiety or agitation)
  • Difficulty concentrating
