Drug Interaction Report

The following interaction applies only if you are receiving the oral formulation of lefamulin (Xenleta), but not the intravenous formulation:

Lefamulin taken orally may increase the blood levels and effects of budesonide. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. Contact your doctor if your condition changes or you experience increased side effects. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

You should avoid the regular consumption of large amounts of grapefruits and grapefruit juice while taking budesonide. Grapefruit can raise the levels of budesonide in your body and lead to increased side effects. Do not increase or decrease the amount of grapefruit products in your diet without first talking to your doctor.

The following interaction applies only if you are taking lefamulin (Xenleta) orally:

Food may interfere with the absorption of lefamulin, which may lead to lower blood levels of the medication and possibly reduced effectiveness. You should take lefamulin at least 1 hour before or 2 hours after a meal. It is best to avoid or limit the consumption of grapefruit and grapefruit juice during treatment with lefamulin, as it may increase blood levels of the medication and increase side effects. Talk to your doctor or pharmacist if you have any questions or concerns.
