Drug-Drug InteractionAudio (En español)

A change in a drug’s effect on the body when the drug is taken together with a second drug. A drug-drug interaction can delay, decrease, or enhance absorption of either drug. This can make either or both of the drugs less effective or more active, or cause adverse effects.
