Chantix and Alcohol – Can You Drink While Taking Chantix?

What Is Chantix?

Chantix is a medication taken to help someone quit smoking and is often used alongside counseling support and behavior modification. Chantix is believed to affect the amount of dopamine released throughout the body and brain. This helps individuals quit smoking since nicotine, when consumed, also releases dopamine. 

The brain views dopamine as a reward since it makes you feel happier and calmer. Nicotine is addictive because your body wants more dopamine, and since nicotine releases dopamine, your brain starts to associate cigarettes with the reward feeling. 

Chantix works by keeping nicotine from attaching to the brain receptors that release dopamine, which removes the reward associated with smoking and helps reduce your craving for cigarettes. Over time, this can help people quit smoking altogether. 

Chantix Usage Schedule

Chantix is the brand name for the medication varenicline, which is prescribed as a pill of two strength options: 0.5 mg, which is a white pill, and 1 mg, a blue pill. 

There are two common ways to use varenicline. The first option is to choose a date when you want to quit smoking and then start taking varenicline a week before your predetermined quit date. Following this technique allows the varenicline to build up in your body before quitting.

The second option is to start taking varenicline and then choose a quit date 8 to 35 days after you begin taking Chantix. 

Those who are prescribed Chantix are often placed on a dosing schedule that changes the longer you take it. 

An example schedule may look like this:

  • Days 1 to 3: one white pill (0.5 mg) each day
  • Days 4 to 7: two white pills (0.5 mg) each day – one in the morning and one at night
  • Days 8+: two blue pills (1 mg) each day – one in the morning and one at night

Nicotine Withdrawal

It’s important to note that those who quit smoking may experience nicotine withdrawal symptoms, which can occur even if you take a medication such as Chantix. 

Symptoms of nicotine withdrawal include feeling depressed, restless, frustrated, angry, or irritated.
