Chantix Stop Smoking Prescription Medication

Varenicline or Chantix is a smoking cessation drug that is prescribed to individuals whore 18 years and over. Besides oral pills, you may incorporate counseling and quit-smoking programs to ensure your gradually quit smoking. Pfizer, the company that manufacturers Chantix, acknowledges that sometimes you may slip up while on Chantix. In such cases, you should maintain the standard dose while making a greater effort to discard the vice.

How Chantix works

It is incredibly important to know how nicotine affects you in order to understand how Chantix can curb your smoking addiction.

When you smoke, Nicotine gets absorbed into the bloodstream. It travels to the brain where it latches onto the nicotine receptors, causing the release of dopamine. The dopamine (a chemical that makes you feel good) creates the psychotropic effect cigarette addicts seek.

Unfortunately, dopamine effects are short-lived, and when the levels drop, you feel the urge to have another cigarette. Even though tar and other carcinogenic compounds cause the greatest health risk, nicotine is the compound that causes cigarette addiction.

Chantix works by latching onto the nicotine-binding receptors in place of nicotine. As a result, dopamine is released, but in low quantities. Pfizer research indicates that when dopamine is released in small quantities, you can curb the cigarette craving.

Most nicotine replacement therapies (NTRs) such as nasal sprays, patches, gum, inhalers, and lozenges, use nicotine to curb smoking. The NTRs simply swap one addictive substance for another without dealing with the nicotine addiction. However, Chantix offers a nicotine-free alternative that is more efficient in reducing the urge to smoke. Ensure you ask your physician about the differences between NTRs and Chantix so that you could make an informed decision on the best option to help you fight your addiction.

How to use Chantix

Even though deciding to quit is a significant first step, you should understand that everyone has his/her ways of quitting smoking. The decision of whether Chantix is the right choice for you should, thus, be made after consulting with your physician. Here are three suggestions to take Chantix:

First, you can take an oral Chantix dose for three months. If you manage to quit smoking by the end of the three months, your physician may give you another three-month Chantix prescription to ensure you do not get the urge to smoke.

Second, your physician may suggest using the Gradual Quitting Approach, which involves taking Chantix continuously for six months (24 weeks). During this period, you should notify your physician if you develop any side effects. You are required to take Chantix pills after meals with a full eight-ounce glass of water.

Third, you can continue smoking after starting your Chantix treatment until you get to your target quit date. The quit date is based on your personal goal to stop smoking. For your body to build up the required levels of Chantix, you should start the dose before the cease date.

How long can I Smoke While on Chantix?

As highlighted above, integrating Chantix into your cigarette smoking can significantly help you stop completely. You can decide on the date to quit and that should be in a week or up to a month. However, if you are unable or unwilling to cease smoking abruptly, you can take Chantix and reduce the number of cigarettes you take by half every month. Keep in mind the goal should be to quit in three months, or sooner.

Three Ways Chantix Helps to Curb Smoking

Quitting smoking is a personal decision and, therefore, you should have control on when and how to cease smoking. For this reason, Pfizer developed three strategies that can help you quit smoking using Chantix.

Fixed quitting approach: The approach is suited for individuals who are willing to cease smoking within a week.

I. After you set a quit date, start taking Chantix around one week before the date.

II. During the week, you can simultaneously take Chantix while smoking.

III. After the quit date, exclusively take Chantix for 12 additional weeks.

IV. Even if you slip up, you should continue taking Chantix.

Research conducted by Pfizer found that 44 percent of those on Chantix entirely ceased smoking in 9-12 weeks as compared to 18 percent who were on a placebo.

Flexible quitting approach: If you want to cease smoking, but you dont want to set a fixed date, the flexible quitting approach might be best for you.

I. Start the Chantix dose before picking a date. Just ensure that the quitting time is within 8-35 days after the onset of the dose.

II. Continuously maintain the Chantix dose for three months

Pfizers research found that 54 percent of those on Chantix entirely ceased smoking in 9-12 weeks as compared to 19 percent on a placebo.

Gradual quitting approach: The progressive quitting approach is suited for individuals who are unwilling or unable to cease smoking in a conventional way.

I. Once you start your Chantix dose, you should ensure you reduce your daily cigarette number by half each month of the treatment.

II. Repeat this each month with the aim of completely ceasing in the last month of the treatment or sooner.

III. Once you complete the three-month dose, take Chantix for an additional three months to reduce the chance of relapse.

Pfizers research found that the gradual quitting approach led to 32 percent of those on Chantix completely ceased smoking by week 15-24 as opposed to seven-percent taking a placebo.

How to take Chantix

Always take Chantix oral pill after meals with a full eight-ounce glass of water. The dose should start low and gradually increase to reduce adverse side effects.
