Drug's Reason for Withdrawal

There are many reasons why drugs that are available for patient treatment could be removed from the market. 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 medical treatments. After any drug ingestion’s reported bad 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 drugs approval or withdrawal. Hospitals and medical doctors from around the world report any new finding to the respective regulatory agency. If there is, a real danger for public safety, or the side effects frequency and severity of them are higher than expected, the reported drug entered in an alert state or warning. Afterwards, if the evidence found shows a clear link between the drug and the negative health effects, the drug might be withdrawn. Concisely, if the risk from using the drug outweighs its potential benefits the drug might be withdrawn or removed from public use or the market.

Notice the difference between a drug recall and a drug withdraw. A drug recall is the temporary market removal of a specific lot or a drug produced for a limited period. Additionally, drug recalls can be observed when the final product contains any unreported chemical or the final product has an undisclosed substance or a contaminated material. Once the corrections are made the can be return to the market.

On the other hand, a drug withdrawal means that the safety, real benefits, efficacy, or functions of the drugs cannot be proven on several clinical studies. Therefore, the drug is labeled as unsafe, dangerous, or inefficient for medical treatments and it is removed from the market. However, the removed drug can be modified and its medical indication can be changed, to be reintroduced as a new medicine with new label indications.

The drugs 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 Because of the permanent pharmaceutical industry supervision, few drugs are withdrawn since most of the time the pharmaceutical company makes a voluntary recall when a serious doubt arise about a particular drug to avoid the legal implications, monetary losses and public scrutiny.
