Zmax suspension is used for:

Treating mild to moderate infections caused by certain bacteria. It may also be used for other conditions as determined by your doctor.

Zmax suspension is a macrolide antibiotic. It slows the growth of, or sometimes kills, sensitive bacteria by reducing the production of important proteins needed by the bacteria to survive.

Do NOT use Zmax suspension if:

  • you are allergic to any ingredient in Zmax suspension, to other macrolide antibiotics (eg, erythromycin), or to ketolide antibiotics (eg, telithromycin)
  • you have a history of liver problems or yellowing of the skin or eyes caused by any doseform (eg, tablets, suspension, injection) of Zmax suspension
  • you have a certain type of irregular heartbeat (QT prolongation), low blood potassium or magnesium levels, or a very slow heartbeat
  • you are taking amiodarone, cisapride, dofetilide, dronedarone, nilotinib, pimozide, procainamide, propafenone, quinidine, sotalol, or tetrabenazine

Contact your doctor or health care provider right away if any of these apply to you.

  • Mild diarrhea is common with antibiotic use. However, a more serious form of diarrhea (pseudomembranous colitis) may rarely occur. This may develop while you use the antibiotic or within several months after you stop using it. Contact your doctor right away if stomach pain or cramps, severe diarrhea, or bloody or watery stools occur. Do not treat diarrhea without first checking with your doctor.
  • Long-term or repeated use of Zmax suspension may cause a second infection. Tell your doctor if signs of a second infection occur. Your medicine may need to be changed to treat this.

Discuss any questions or concerns with your doctor.
  • Be sure to use the entire dose of Zmax suspension. If you do not, the medicine may not clear up your infection completely. The bacteria could also become less sensitive to this or other medicines. This could make the infection harder to treat in the future.
