Medication Information

Medication research is most useful when it starts with the exact drug and product being discussed. A medication may be identified by a brand name, a generic name, or its active ingredient, and different products may have different strengths, dosage forms, manufacturers, and labeling.

Start with the medication identity

When researching a medication, useful details include:

the active ingredient;
brand and generic names;
strength and dosage form;
whether the product is prescription or nonprescription;
the manufacturer or labeler when product-specific information matters;
the current label or package information.

FDA-approved generic drugs use the same active ingredient as the corresponding brand-name drug and must meet FDA requirements for approval. Product-specific details can still differ, so the exact label remains important when answering a question about a particular medication.

Use authoritative drug information

FDA resources and the National Library of Medicine’s DailyMed database are useful starting points for researching drug approval information and current labeling submitted to FDA. DailyMed can be searched by drug name, manufacturer or labeler, drug class, or National Drug Code when that information is available.

Medication labeling can provide information such as indications, warnings, precautions, adverse reactions, drug interactions, and instructions associated with a particular product. General website summaries should not override the current label or patient-specific advice from a healthcare professional.

Questions for the pharmacy or prescriber

If the question concerns an individual prescription, current medication use, a possible change in treatment, or how several medications fit together, discuss it with a pharmacist or the prescribing clinician as appropriate. It can help to have the medication name, strength, dosage form, and current label available.
