Chantix is a medication used to help people stop smoking. It is available in pill form and requires a prescription from a doctor. The MayoClinic.com reports that Chantix works by blocking the effect that nicotine has on the brain. Chantix stimulates the release of low levels of dopamine and other chemicals in the brain just like nicotine does. As a result, signs and symptoms of nicotine withdrawal are decreased because the brain still behaves as though it is receiving nicotine stimulation. In addition, Chantix blocks nicotine receptors in the brain, so nicotine from a cigarette does not stimulate the brain in the way it did before using Chantix. As a result, smoking becomes less desirable and cravings for nicotine subside. Patients typically begin taking Chantix a week before they intend to quit so as to prepare the brain for the upcoming lack of nicotine. Chantix is usually taken once a day at first and then increased to twice a day. Patients take Chantix for 12 to 24 weeks depending upon their physician's recommendation.
Chantix Side Effects
RxList warns that serious neuropsychiatric symptoms have been seen in patients taking Chantix. These symptoms include depression, hallucinations, delirium, paranoia, homicidal ideation, agitation, anxiety, suicidal ideation, suicide attempt, and completed suicide. These symptoms have been reported in patients with and without a prior history of depression, anxiety or other mood disorder. Anyone taking Chantix who experiences a change in mood or behavior should seek medical attention immediately.
Another possible side effect of Chantix includes allergic reaction. Symptoms of a Chantix allergy include swelling of the face, mouth neck or extremities, difficulty breathing, chest pain and hives. Some patients have experienced severe skin reactions when taking Chantix. These reactions include redness, swelling and flaking of the skin. Anyone who experiences symptoms of an allergic reaction while taking Chantix should stop taking the drug and seek immediate medical attention.
Other side effects of Chantix may include nausea, headache, vomiting, insomnia, abnormal dreams and change in the way food tastes.
Contraindications of Chantix
RxList reports that the use of Chantix is contraindicated in patients under the age of 18 or anyone who is pregnant, plans to become pregnant, or nursing. Chantix has not been approved by the Food and Drug Administration for use in these populations. Also, anyone with a history of kidney disease or impairment may need to take a lower dose of Chantix. Consultation with a physician is necessary in order to determine a safe dose in this situation. Anyone with a history of depression, anxiety or other mood disorders should use caution when taking Chantix due to the risk of worsening symptoms of depression, anxiety or suicidal thoughts or actions. Anyone taking Chantix who experiences changes in his mood or behavior should consult a doctor immediately for further advice.
Efficacy of Chantix
The MayoClinic.com reports that some studies have shown Chantix to be more effective than a placebo in helping people quit smoking. Research has also shown that more people are able to remain smoke-free with the use of Chantix. People also reported experiencing fewer withdrawal symptoms and less pleasure from smoking a cigarette when using Chantix. However, according to the MayoClinic.com, the overall success rate of participants involved in Chanitx studies reveals that only 23 percent of participants remained smoke-free after one year. So while research for Chantix looks hopeful initially, the long-term benefits of it remain to be seen.
