There are some side effects associated with these drugs. It takes some time for the body to get used to them. Therefore, they are taken in low doses initially and then the dosage is gradually increased. Varenicline can cause side effects like nausea, flatulence, hallucinations, constipation, abnormal dreams, sleeping trouble and headache.

Bupropion can cause side effects like anxiety, headache, insomnia, dry mouth, irritability and in rare cases, seizures.
