Question 1

How soon after starting Zyban will I notice reduced cravings?

Accepted Answer

Most people start feeling a reduction in nicotine cravings during the second week of treatment, around the time they set their target stop day.

Question 2

Can Zyban work immediately after the first tablet?

Accepted Answer

No, it needs time to build up in your system. You continue smoking during week 1, then aim to quit in week 2 when levels are therapeutic.

Question 3

How long does Zyban stay in your system after stopping?

Accepted Answer

Bupropion has a half‑life of about 20 hours, so it takes roughly 5–6 days to be completely eliminated from the body.

Question 4

Why do I need to wait until week 2 to stop smoking?

Accepted Answer

Because it takes about 8 days to reach steady‑state concentrations where the medicine is fully effective at reducing cravings and withdrawal.

Question 5

Does food affect how fast Zyban works?

Accepted Answer

Food does not significantly change absorption; you can take it with or without meals. However, if nausea occurs, taking with food may help.
