Varenicline is a medicine that helps people stop smoking. When you smoke, your brain gets used to the nicotine in cigarettes and starts to think it needs it. Sometimes when you try to quit smoking, your brain makes you feel nervous, angry, or sad.
Varenicline helps your brain by making it think you already have nicotine, so you don't feel like smoking. It also helps to reduce the feeling of pleasure you might get from smoking, so you don't crave it as much.
You take varenicline as a pill, usually for a few weeks. It's important to follow the instructions from your doctor or pharmacist, and keep taking the medicine even if you don't feel any different at first.
Remember, smoking is not good for you and can hurt your body. Varenicline can help you quit smoking so that you can be healthier and happier!
