Home Products Medicine Safety Partnering With Patients

Do you know how medicines are studied? 

Healthcare providers, pharmaceutical companies, regulatory authorities (like the FDA) and patients work together to better understand and reduce risks of medicines. This extensive safety system is called Pharmacovigilance (PV). Pfizer has thousands of experts around the globe working to analyze and communicate the risks and benefits of our medicines both before and after they are approved for use. Patients also have an important role to play in reporting side effects they may experience.

Safety is everyone’s first priority, but medicines may still have side effects.

It takes studying thousands of possible new medicines by companies like Pfizer to get ONE through the drug development process and approved by regulatory authorities such as the FDA.7
Pfizer’s medicines are available in over 150 countries around the world. We employ thousands of medicine safety specialists. These specialists work with regulatory authorities to understand and communicate the risks and benefits of our medicines both before and after they are approved for patients.

Companies like Pfizer and regulatory authorities like the Food and Drug Administration (FDA) make every effort to understand:

Identifying and managing possible safety concerns associated with the medicines we take




Helping protect patients


Drug companies, healthcare providers and regulators are always monitoring for medicine safety, both before and after a medicine has been approved.


Clinical trials often find common side effects of a medicine, but some effects can only be found when large numbers of people are using the medicine after it is approved.
You, the patient or caregiver, are an important part of this network.10
