Zyflo

Possible food and drug interactions when taking Zyflo

If Zyflo is taken with certain other drugs, the effects of either could be increased, decreased, or altered. You should check with your doctor before stopping or starting any prescription or nonprescription medicine. This is especially important with the following:

Astemizole (Hismanal)
Beta blockers (a type of heart and blood pressure medication) such as Inderal, Sectral, and Tenormin
Calcium channel blockers (another type of heart and blood pressure medication) such as Calan, Cardizem, and Procardia
Cisapride (Propulsid)
Cyclosporine (Sandimmune, Neoral)
Terfenadine (Seldane)
Theophylline (Theo-Dur)
Warfarin (Coumadin)

While you are taking Zyflo, your theophylline dosage may need to be lowered, and your theophylline levels will have to be carefully watched. Dosages of Inderal may also need reduction, and warfarin dosages may need adjustment as well.

Special information if you are pregnant or breastfeeding

The effects of Zyflo in pregnancy have not been adequately studied. If you are pregnant or plan to become pregnant, ask your doctor whether you should continue taking Zyflo. It is not certain that the drug appears in breast milk, but taking Zyflo while nursing is not recommended. Discuss with your doctor whether it's best to stop taking the drug or to give up breastfeeding.
