What is Chantix

VareniclineThe Generic name of this drug

Treatment SummaryVarenicline is a prescription drug used to help people quit smoking. It is a type of medicine called a nicotinic receptor partial agonist. This means it has special effects on certain types of receptors in the body. Varenicline can increase the risk of seizures and may cause people who drink alcohol while taking the drug to become aggressive or lose consciousness. Pfizer Inc is conducting a study to find out more about the safety of this drug, and the results will be released in late 2015. Until this study is completed, the FDA will keep a warning printed on the drug packaging.

Effectiveness

How Chantix Affects PatientsVarenicline is a drug designed to activate the parts of the brain that nicotine usually stimulates, while blocking nicotine from attaching to those parts.

How Chantix works in the bodyVarenicline is a drug that helps people quit smoking by attaching itself to the same receptors that nicotine attaches to in the brain. It is much weaker than nicotine, so it doesn't make you feel as good, but it helps reduce the urge to smoke and can help with withdrawal symptoms. It is highly selective, meaning it only affects certain receptors and not others, so it's safer than many other drugs.

Chantix Reviews: What are patients saying about Chantix?

Chantix for Stop Smoking

I was a 44 year smoker who had tried to quit many times before. I decided to try Champix and by the end of the first packet, I had stopped smoking. I only experienced side effects like feeling nauseous when thinking about cigarettes after day 8. I didn't even need the second month's dose but kept them on hand just in case. It's been 16 months since I've smoked and I don't even crave cigarettes when around other smokers

Chantix was a game-changer for me. I'd been trying to quit smoking on my own for years without success, but this medication really helped to lessen my urges. After just two weeks, I was able to stop completely!

Chantix for Stop Smoking

I started chantix while I was in rehab for my nicotine addiction. I wanted to avoid becoming dependent on other nicotine replacement therapies like patches, so I decided to try this medication. It's been over two months now and I haven't smoked at all. I still have strong cravings occasionally, but this drug has definitely helped me kick my habit for good.

My wife and I started taking Chantix, and we were both able to quit smoking within a month. We still haven't gone back, 20 months later. If you're struggling to quit smoking, I highly recommend giving this drug a try.

Chantix for Stop Smoking

This medication was successful for me. I recommend getting a prescription for ativan from your doctor or psychiatrist to help with the depression and anxiety caused by chantix. I also suggest having Nicoderm patches on hand to deal with cravings.

Chantix for Stop Smoking

So far, this has been the most successful attempt I've made to quit smoking. I'm not experiencing nicotine cravings, and deep breathing has really helped with stress management. That said, I did have some nausea when taking the recommended two pills per day; cutting back to one pill has alleviated that issue.

Chantix for Stop Smoking

I have experienced some negative side effects, like nightmares and pressure in the back of my head. However, this medication is still helpful and I stopped taking it because I returned to smoking cigarettes.
