Chantix is a prescription medication used to help people quit smoking cigarettes. It is often used in combination with other smoking-cessation programs, such as counseling or a support group. Chantix is taken orally in pill form. The dosage of the pills and the number of pills taken each day changes to lessen the likelihood of side effects and to help wean users off nicotine.
How It Works
Chantix interferes with the brain's nicotine receptors. It also is thought that Chantix reduces the amount of dopamine released in the brain. Chantix does not contain nicotine, as some smoking-cessation products do.
Effectiveness
In studies conducted by Chantix maker, Pfizer, 44 percent of Chantix users were able to quite smoking in 9 to 12 weeks, compared with 18 percent of people taking a placebo. The study included 1,022 long-time smokers who smoked at least 10 cigarettes a day.
Side Effects
Some people using Chantix will experience constipation, vivid or unusual dreams, nausea or upset stomach, vomiting, headaches, increased appetite, gas, difficulty sleeping or changes to taste. None of these side effects is cause for concern. However, contact your doctor if you experience any of the following side effects, which may indicate a problem: chest pain; a fast, slow or irregular heartbeat; new or worsening mood problems; changes to behavior; memory loss; hallucinations; suicidal thoughts or actions; seizures; vision changes; and severe or persistent nausea.
Warnings
Chantix may not be safe for people with certain medical conditions, including mental illnesses or kidney disease, especially those requiring dialysis. Chantix can cause drowsiness or dizziness in some, so users should be cautious when performing tasks requiring focus or concentration, such as driving, until they know how it will affect them.
Drug Interactions
Using Chantix while also using a nicotine-replacement therapy can increase the odds and severity of experiencing many side effects, including nausea and vomiting, tiredness, headaches and dizziness.
