There is no universally best stop-smoking medicine. The most effective practical option is one that is safe for you, controls your main withdrawal pattern and can be followed for the full course. Access and authorised regimens vary across European countries.

Varenicline and cytisine

Both act partially at nicotine receptors and do not supply nicotine. Varenicline commonly uses a gradual start around a quit date and may cause nausea or vivid dreams. Cytisine uses a product-specific tapering schedule with an early stop date. Kidney function, cardiovascular history, pregnancy and other risks influence choice.

Nicotine replacement

NRT is available in several forms and allows flexible combination of steady and rapid relief. It is familiar and can suit people who want control over breakthrough cravings. Skin irritation, mouth or throat effects and technique problems vary by formulation. Continuing to smoke heavily while using it should trigger advice, not secret dose changes.

Bupropion

Bupropion is a non-nicotine tablet that can reduce cravings for suitable adults. Insomnia, dry mouth and headache can occur. Seizure disorders, eating disorders, some alcohol or sedative withdrawal situations and multiple medicine interactions can make it unsuitable.

When to seek help

Seek urgent help for chest pain, a seizure, a severe skin or allergic reaction, or thoughts of self-harm. New or marked changes in mood or behaviour should be discussed promptly. Pregnancy, breastfeeding, recent cardiovascular events, kidney disease, seizure history, mental-health treatment and other medicines can change the safest option.

What to prepare for a medical review

A practical review covers cigarettes or other tobacco used per day, time to the first cigarette, previous quit attempts, withdrawal pattern, alcohol or other triggers, current medicines, health history and preferred quit date. The aim is not to judge motivation. It is to match support and, where appropriate, medication to the moments when relapse is most likely.

A calm next step

Compare options with a clinician or pharmacist using your medical history and past attempts. A planned switch after side effects is safer than abandoning treatment and returning to smoking without support.
