Which of the following is NOT a documented side effect of Varenicline?

Varenicline, a medication commonly used to help people quit smoking, is associated with several side effects that have been studied and documented. Among these, vivid dreams, nausea, and skin reactions have all been reported as potential side effects in users.

Nausea is one of the most frequently reported side effects when taking varenicline, occurring due to its action on the brain’s nicotine receptors. Vivid dreams can also occur, possibly linked to the way varenicline affects neurotransmitter levels. Skin reactions include various dermatological side effects that some users experience while on this medication.

In contrast, excessive eating is not recognized as a documented side effect of varenicline. While changes in appetite can occur with various medications, excessive eating itself is not a characteristic side effect typically associated with this drug. This distinction is important for users to understand, as it highlights that weight gain or alterations in eating behavior related to appetite are not generally linked to varenicline treatment.
