Side effects can overlap with nicotine withdrawal, which makes timing important. Irritability or poor sleep may come from quitting, a medicine or both. A planned review helps separate expected adjustment from a reason to change treatment.
Varenicline and cytisine
Nausea, headache, sleep disturbance, vivid dreams, dry mouth and appetite changes can occur. Gradual dose schedules are designed partly for tolerability. Persistent palpitations, major blood-pressure changes, chest symptoms, seizures, severe skin reactions or concerning mood changes require prompt advice.
Nicotine replacement
Patches can irritate skin or disturb sleep; gum can cause jaw soreness, hiccups or indigestion when chewed too quickly; sprays can irritate the nose or throat. Palpitations, marked nausea or dizziness may indicate too much nicotine or another problem. Technique and dose should be reviewed before the whole approach is discarded.
Bupropion
Dry mouth, insomnia, headache, nausea and anxiety can occur. Seizures are uncommon but serious, which is why dose limits and contraindications matter. New suicidal thoughts, severe agitation, a seizure or an allergic reaction needs urgent help.
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
Keep a simple daily note of medicine timing, cigarettes smoked, cravings, sleep and symptoms during the first two weeks. Contact the prescriber before stopping suddenly, changing the dose or combining treatments on your own at any stage.
