Using this medicine while you are pregnant can harm your unborn baby. Use an effective form of birth control to keep from getting pregnant during treatment and for at least 2 days after the last dose. If you think you have become pregnant while using this medicine, tell your doctor right away.
Do not use this medicine if you are also using erythromycin (Ery-Tab®), moxifloxacin (Avelox®), medicine to treat heart rhythm problems (eg, amiodarone, quinidine, procainamide, sotalol, Betapace®, Cordarone®), medicine to treat mental illness (eg, pimozide, Orap®), or tricyclic antidepressants. Using these medicines together with lefamulin may cause unwanted serious side effects.
Contact your doctor right away if you have any changes to your heart rhythm. You might feel dizzy or faint, or you might have a fast, pounding, or uneven heartbeat. Make sure your doctor knows if you or anyone in your family has ever had a heart rhythm problem such as QT prolongation.
Lefamulin may cause diarrhea, and in some cases it can be severe. It may occur 2 months or more after you stop taking this medicine. Do not take any medicine to treat diarrhea without checking first with your doctor. Diarrhea medicines may make the diarrhea worse or make it last longer. If you have any questions about this or if mild diarrhea continues or gets worse, check with your doctor.
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
