Answer

Macrolides, as a class, have the potential disadvantage of causing gastrointestinal (GI) upset. Compared with erythromycin, newer agents have fewer GI adverse effects and drug interactions, although all macrolides have the potential for drug interactions similar to those of erythromycin. Newer macrolides offer improved compliance because of reduced dosing frequency, improved action against H influenzae, and coverage of Mycoplasma species (unlike cephalosporins). The main disadvantage is cost.
