Most drugs of abuse are addictive. Addiction is a chronic, relapsing disease characterized by compulsive drug seeking and use despite negative consequences and by long-lasting changes in the brain. People who are addicted have strong cravings for the drug, making it difficult to stop using. Most drugs alter a person’s thinking and judgment, which can increase the risk of injury or death from drugged driving or infectious diseases (., HIV/AIDS, hepatitis) from unsafe sexual practices or needle sharing. Drug use during pregnancy can lead to neonatal abstinence syndrome, a condition in which a baby can suffer from dependence and withdrawal symptoms after birth. Pregnancy-related issues are listed in the chart below for drugs where there is enough scientific evidence to connect the drug use to negative effects. However, most drugs could potentially harm an unborn baby.

Letrozole has been used for ovarian stimulation by fertility doctors since 2001 because it has fewer side-effects than clomiphene ( Clomid ) and less chance of multiple gestation. A study of 150 babies following treatment with letrozole or letrozole and gonadotropins presented at the American Society of Reproductive Medicine 2005 Conference found no difference in overall abnormalities but did find a significantly higher rate of locomotor and cardiac abnormalities among the group having taken letrozole compared to natural conception. [6] A larger, follow-up study with 911 babies compared those born following treatment with letrozole to those born following treatment with clomiphene. [7] That study also found no significant difference in the rate of overall abnormalities, but found that congenital cardiac anomalies was significantly higher in the clomiphene group compared to the letrozole group. Despite this, India banned the usage of letrozole in 2011, citing potential risks to infants. [8] In 2012, an Indian parliamentary committee said that the drug controller office colluded with letrozole's makers to approve the drug for infertility in India and also stated that letrozole's use for infertility was illegal worldwide; [9] however, such off-label uses are legal in many countries such as the US and UK.

Androgens are responsible for the growth spurt of adolescence and for the eventual termination of linear growth, which is brought about by fusion of the epiphyseal growth centers. In children, exogenous androgens accelerate linear growth rates but may cause a disproportionate advancement in bone maturation. Use over long periods may result in fusion of the epiphyseal growth centers and termination of growth process. Androgens have been reported to stimulate the production of red blood cells by enhancing the production of erythropoeitic stimulating factor. During exogenous administration of androgens,  endogenous testosterone  release is inhibited through feedback inhibition of pituitary luteinizing hormone (LH).

Cimetidine was first marketed in the United Kingdom in 1976, and in the . in August 1977; therefore, it took 12 years from initiation of the H 2 receptor antagonist program to commercialization. By 1979, Tagamet was being sold in more than 100 countries and became the top-selling prescription product in the ., Canada, and several other countries. In November 1997, the American Chemical Society and the Royal Society of Chemistry in the . jointly recognized the work as a milestone in drug discovery by designating it an International Historic Chemical Landmark during a ceremony at SmithKline Beecham's New Frontiers Science Park research facilities in Harlow, England.

In July 2011, FDA began a pilot program to notify people of drug recalls before they are classified in an effort to expedite notifications of human drug product recalls to the public. FDA is now able to accomplish the goal of expedited notification within the Enforcement Report. These recalls are identified within the Enforcement Report by the label of “Not Yet Classified” in the “Classification” column. It is also possible to search the Enforcement Report for these “Not Yet Classified” recalls using the filter drop down menu. Therefore, as of September 15, 2017 FDA will discontinue the pilot program, and will no longer post drug recalls that are pending classification on this webpage. To see posted recalls that are pending classification go to the weekly Enforcement Report.
