When you find out that you're pregnant, quitting smoking is one of the best things you can do for your baby. But if you used a smoking cessation drug such as Zyban while pregnant, you should be aware that the use of this drug has been linked to harmful and potentially fatal birth defects.

Zyban Side Effects

Zyban, generically known as bupropion hydrochloride, is manufactured by GlaxoSmithKline and was originally approved in a stronger form, Wellbutrin, by the FDA in 1985 as an antidepressant. Wellbutrin has also been associated with serious or even fatal birth defects. 

In May 1997, Zyban, a lower dose of bupropion was approved for use as a smoking cessation aid and helps to reduce the side effects associated with nicotine withdrawal.

The drug, however, carries a Pregnancy Category C classification, meaning that animal reproduction studies have shown an adverse effect on fetuses but that no adequate or well-controlled studies in humans have been performed.

In 2010, the American Journal of Obstetrics & Gynecology released a study that found that children of mothers who “used bupropion during early pregnancy had more than double the risk of heart defects known as left outflow tract defects, compared with infants whose mothers had not used the drug,” according to Reuters.

Congenital heart defects affect approximately 40,000 babies each year, and one of the primary known causes of such birth defects is the ingestion of teratogenic drugs during pregnancy. A teratogen is a drug or other substance capable of interfering with the development of a fetus that can ultimately result in serious birth defects.
