Drugs are organized into categories by drug classification. A class of drugs is a group of similar medications. The list of drugs in each drug class may work similarly, they may have a comparable chemical structure, or they could treat similar medical conditions. Use the following resource guides to learn more about the common drug classes, how they work, and what they cost.
Browse drug classes by letter:
Browsing medications by drug classes can be especially helpful if you are looking for alternatives to a drug you’ve been prescribed. You may be looking for a similar drug that doesn’t cause as many side effects or has fewer drug interactions. Drug prices are another good reason to look for drug alternatives. For example, by researching CNS stimulants, you may find that Adderall could be more affordable than Vyvanse. Use these drug class guides to inform conversations with your healthcare provider about finding the right medication for you.
