Understanding the uses, benefits, and possible side effects of available medications gives patients the opportunity to consider the full scope of possibilities in their care. As a health sciences student, I would encourage patients to create an open dialogue with their healthcare providers about their medications. This dialogue can improve medication adherence and ultimately lead to better health outcomes. For further information on a medication you might be taking, explore the links below.

Common Websites for Medication Information 

When seeking reliable information about medications and drugs, several reputable websites are commonly used by healthcare professionals and patients alike:
