Definition: A Medication Guide is FDA-approved patient labeling that must be handed to the patient with certain prescription drugs. FDA requires one when patient labeling could help prevent serious side effects, when a serious risk could change a decision to use the drug, or when following directions closely is crucial.
FDA lists three reasons a drug gets a Medication Guide:
The drug company writes it and FDA approves it. It must be given in paper form when the drug is dispensed, though a patient may ask for an electronic copy instead. The rules are in 21 CFR 208.
FDA-approved patient labeling comes in three kinds: Medication Guides, Patient Package Inserts and Instructions for Use. Not every prescription drug has any of them. The printed sheets many pharmacies staple to the bag are different again. FDA calls those consumer medication information and says it does not review or approve them.
The Fosamax label, for example, is published as prescribing information plus a Medication Guide in one document.
The Medication Guide is written in plain language and lists the warning signs the maker wants you to act on. It is a short companion to the full prescribing information, not a replacement.
