Strange flashes
Date: 8/9/2015
I was taking Chantix for 2 months. Did stop smoking but couldn't take some side effects anymore. Now that I stopped I'm getting these strange flashes running through my body. Mostly when laying down and trying to sleep. It's been 3 days off the drug now. Is this normal and will it go away? Driving me nuts.....

AskDocWeb: The manufacturer of Chantix (Pfizer) lists hot flush (hot flashes) as one of the "frequent" adverse events reported by those taking this drug. Always tell your doctor if any side effect is severe or does not go away.

Liver damage?
Date: 9/19/2015
I started chantix 3 weeks ago and it worked wonders for the cravings. But at 2 1/2 weeks I started feeling sick with stomach pains (nausea/vomiting) right underneath the rib cage. I was told by the ER that my liver enzymes are almost doubled. This freaks me out and it will be a a couple weeks till I can see a G.I. ls this something is really bad?

AskDocWeb: This is one of the areas where we think that the black box warning is failing to cover. Monitoring early side effects can prevent serious consequences. For example, if a side effect of a medication is liver damage, then monitoring a patient's liver enzymes for evidence of early liver injury can prevent serious disease by alerting the physician to this side effect so that the medication can be discontinued before it causes actual liver damage.

Chantix review - Success
Date: 10/27/2015
My husband took Chantix and stopped smoking 8 years ago this October! He still can't believe that he is a non-smoker. He tried every other way to stop before with no success. He started as prescribed by his Dr. and smoked the first week. By the second, third and fourth weeks he was down to a few cigs per day. The only side effects he had to that point was crazy dreams which were fun to hear about the next day and coffee didn't taste good to him so he stopped drinking it and switched to tea. (Wow).

He was down to 1 cig. per day by week 5 1/2 and started to be a little too angry about small things. I was ready to call his Dr. to ask when she was to see him again and tell her I noticed a change in mood. That same day he told me that it was making him feel weird and was going to stop smoking all together because he said that it was stupid to keep smoking only one per day. He was ready to Quit. I told him that was good and explained my concern of his recent mood change. He agreed but did not understand my full concern. It took 5 1/2 weeks to stop smoking on Chantix.

After 3 months of no smoking or Chantix he started to drink coffee again but it is just 1 or maybe 2 cups per day. Obviously we are happy, but we did discuss the side effects when he started the medication so at least one of us would recognize the changes the minute something seemed different. I feel that you must have someone close to you that can monitor you while you are using this just in case.

It's heartbreaking now for my husband who's mother has been a lifelong smoker and was just diagnosed with inoperable lung cancer. Even with his good results she refused to try to stop and now it is too late. Good luck and I would say that if you have tried every other way to quit, give this a try.

PS After first day no cigarettes, he stopped his horrible snoring. Day 3 the whites of his eyes were completely clear. It only got better for him. Even after 8 years he has said that during a stressful day at work it will pop into his mind that a cigarette would taste good. He says that the thought lasts 3 seconds and then it goes away, so you must want to truly stop and you will.

blurry vision
Date: 12/12/2015
I took it for four weeks, stopped smoking three weeks in. I smoked up to three packs a day. The problem is my vision is so blurry, I think I'd been better off smoking.

Ecstasy while on Chantix?
Date: 5/5/2016
I am taking Chantix for my smoking to help me quit and I want to know what the reaction would be if I were to take ecstasy while on a Chantix regimen.

AskDocWeb: To our knowledge that has not been studied. However, our best guess is that after the temporary high wore off you would find that your ability to experience pleasure would be reduced to some degree for the rest of your life.

Urine tests?
Date: 5/25/2016
Does chantix show up on urine tests?

AskDocWeb: No. For an extensive list of things that might show up on urine tests for drugs of abuse see the page about False Positives.
