Why Are Drugs Removed from the Market?

Drugs that are available for patients treatment can be removed from the market for many reasons. Several regulatory agencies, medical societies, and watchdog groups are permanently monitoring and recording any possible side effect or adverse reaction to the thousands of currently approved pharmaceutical treatments. Therefore, after any therapeutic substance reported adverse outcome, an investigation file is opened, and new evidence is added to it as soon as it is found.

Each country has its own policies for medicament approval and withdrawal. Hospitals and doctors from around the world report any new finding to the respective regulatory agency. Consequently, If there is a threat to public safety or the side effects frequency and severity of them are higher than expected, the reported medication entered in an alert state or warning period. Afterward, if the evidence shows a clear link between the medicament and the adverse health effects, the healing agent may be retired. Concisely, if the risk of using the pharmaceutical product outweighs its potential benefits, the medication is withdrawn. It is removed from public use or the market.

What Is The Difference Between a Drug Recall and a Drug Withdrawal?

A drug recall is the temporary market removal of a specific lot or a pharmaceutical substance produced for a limited period. Additionally, particular recalls can be observed when the final product contains any unreported chemical, or the final product has an undisclosed substance or a contaminated material. After the corrections are made, the medicament may return to the market.

On the other hand, a drug withdrawal means that the safety, real benefits, efficacy, or functions of the medicament cannot be proven in several clinical studies. For these reasons, the medicinal substance is labeled as unsafe, dangerous, or inefficient for medical treatments. Under those circumstances, the investigated pharmaceutical product is removed from the market. However, the removed drug can be modified, and its medical indication can be changed. In that case, the previously removed healing agent may be reintroduced as a new medicine with new label indications.

The medicines included in this article are from the United States Food and Drugs regulatory agency (the FDA) and the European Medicines Agency (EMA). Because of the permanent pharmaceutical industry supervision, fewer drugs are withdrawn every year. Furthermore, the pharmaceutical companies often make a voluntary recall when a serious doubt arises about a particular medicament to avoid the legal implications, monetary losses, and public scrutiny associated with it.

The number of drugs removed from the market has been reducing over time. The pharmaceutical industry follows the highest safety guidelines to avoid exposing the patient to unknown risk. The legal settlements obtained along the years have increased the safety measurements and the speedy answer of this industry to recall voluntarily any high risk or harmful medication.

Unfortunately, there are some side effects or negative associations, which are discovered only after several years of patients’ exposure to it. However, thanks to the information, exchange across diverse medical societies, regulatory agencies, and watchdog groups, any potential detrimental effect caused by a particular drug is rapidly addressed. Thus, consumer safety is protected either by the public pressure on the regulatory agencies or by the voluntary recall of the pharmaceutical company.
