The stop smoking pill is used to negate or reduce the effect of withdrawal symptoms that appear when an individual tries to quit smoking. Most of these pills use Bupropion hydrochloride to combat withdrawal symptoms.

Two popular anti-smoking pills are Zyban and Wellbutrin. Zyban increases the circulation and release of endorphins by stimulating the pituitary gland. The endorphins, in turn, boost the energy levels and make a person feel good. They also create a sense of false pleasure similar to the one experienced while smoking.

The pill is available in a tablet form and should be taken regularly for a week. This is very important for the drug to act. Individuals who stop taking Zyban after one or two days or take it intermittently are rarely benefited. Traces of the drug must be present in the bloodstream for at least a week.

Also, the drug should be taken only on medical advice. Its normal course runs over 8-12 weeks. During this period the individual must consult the doctor regularly to avoid any side effects. The maximum dose prescribed for a single day is two tablets.

The drug should be avoided by people who are suffering from stomach disorders like anorexia or bulimia. This drug was initially used for treating depression hence it should not be taken by people who are on medication, especially those who are using monoamine oxidize inhibitors for treating depression. It has been observed that the drug may lead to seizures or fits in few cases. That is why the drug should be avoided by people who suffer from epileptic fits and seizures.

Insomnia and dry mouth are the side effects linked to the tablet. These symptoms are usually not harmful and recede after a period of time. The tablet can also be taken by people who are suffering from bronchitis or other pulmonary disorders.
