Varenicline, an Effective Drug to Quit Smoking
Varenicline is a drug for quitting smoking. It's very safe and even patients with chronic diseases can use it.
The drug Varenicline is a first-line treatment to quit smoking and reduce nicotine dependence. The effectiveness of this type of pharmacological treatment surpasses previous treatments, according to scientific evidence.

- Minimize withdrawal symptoms
- Reduce the pleasurable effects of nicotine in the brain
- Provide positive reinforcement
The smoking disease
This disease has a high prevalence in the general population and its morbidity and mortality rates are high. In fact, it’s one of the leading causes of preventable death in the world. It’s also the main risk factor associated with diseases such as lung cancer and chronic inflammatory lung disease.
In addition, smoking leads to high health care costs that one can reduce by investing in a smoking cessation treatment. It’ll always be less expensive to invest in prevention rather than in definitive treatments once there’s a major disease.
How does varenicline work?
Labs developed this medication from an alkaloid present in several plant species. Researchers discovered these plant varieties because some Eastern countries have been using them for a long time.
Varenicline is specifically designed for smoking cessation as it selectively binds, partially, to nicotinic receptors in the brain.
Thus, it helps control the withdrawal syndrome and the uncontrollable desire to smoke by reducing anxiety symptoms and rewarding and reinforcing those areas targeted by smoking.
Characteristics of varenicline
This drug isn’t significantly different in terms of how it enters and moves around the body in terms of sex, age, race, and interaction with other medications. Varenicline is quite safe and the scarcity of side effects greatly facilitates its use.
Pharmaceutical companies market it in tablet form for oral administration. The body absorbs it well and people can take it with or without food. Its maximum concentration happens 3 to 4 hours after taking it, and it leaves the body in the urine. There’s hardly any metabolization — no chemical transformations of its structure.
Treatment with varenicline
It follows this protocol:
- 0.5 mg once a day from days one to three
- 0.5 mg twice a day from days four to seven
- Finally, 1 mg twice a day on day eight and until the end of treatment
It isn’t necessary to stop smoking during the first seven days of treatment; however, a person must stop by the eighth day.
The duration of this treatment is 12 weeks, although some people stop earlier due to the deceptive sensation of having attained success. Know that quitting before the end of the 12-week treatment can lead to a relapse. Thus, the person must resume treatment as soon as possible.
The most frequent ones are:
- Nausea is the most frequent side effect of this drug
- Sleep disorders with insomnia
One can minimize nausea by taking varenicline tablets with meals. In addition, you can deal with insomnia by moving the second dose of the day forward. However, be aware that insomnia can also be due to withdrawal syndrome. People often think this is a side effect of the drug, but it isn’t.
