Moderate

itraconazole lansoprazole

Applies to: Onmel (itraconazole) and amoxicillin / clarithromycin / lansoprazole

Talk to your doctor before using itraconazole together with lansoprazole. By reducing stomach acid, lansoprazole can decrease the absorption and blood levels of itraconazole and make the medication less effective against fungal infections. Your doctor or pharmacist may be able to offer suggestions on safer alternatives if you require treatment for stomach acid or ulcer while you are being treated with itraconazole. However, if your doctor does prescribe these medications together, taking itraconazole with an acidic beverage such as a cola may help. 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.
