What Drugs Interact With Diflucan?

Diflucan may interact with blood thinners or seizure medications.

Diflucan may also interact with alfentanil, fentanyl, clopidogrel, cyclophosphamide, cyclosporine, methadone, pimozide, prednisone, saquinavir, zidovudine, sirolimus, tacrolimus, theophylline, voriconazole, antidepressants, cancer medicines, cholesterol lowering medicines, heart or blood pressure medications, nonsteroidal anti-inflammatory drugs (NSAIDs), oral diabetes medications, rifabutin, rifampin, or sedatives.

What Drugs Interact With Flagyl?

Flagyl may interact with blood thinners or seizure medications.

Flagyl may also interact with cimetidine, lithium, or disulfiram.

How Should Diflucan Be Taken?

Diflucan is available in several strengths and comes as a tablet (50, 100, 150 and 200 mg strength), liquid (350 or 1400 mg strength), or injection (2 mg per ml). Diflucan is taken once a day and may be taken for several weeks depending on the condition being treated.

How Should Flagyl Be Taken?

Flagyl is supplied in 250 and 500 mg strength tablets, Flagyl ER is available in 750 mg strength tablets, and Flagyl Injection in 500 mg strength in a buffered 100 ml vial. Dosage is quite variable and dependent upon the severity of disease and other considerations made by the treating physician. Most of the serious side effects may occur with any of these three preparations of Flagyl. Flagyl may cause liver enzyme levels to increase; lithium and creatinine levels should be checked to avoid lithium toxicity or renal compromise. Alcohol may increase the side effects of Flagyl. Patients on disulfiram should not take Flagyl until they have had a two week interval without taking disulfiram, especially alcoholic patients, to avoid psychotic reactions. Treatment in pregnant women (during first 3 months is not advised) or women who are breastfeeding should only be done if the benefits outweigh the potential problems. Flagyl passes into breast milk and may harm a nursing baby. Consult your doctor before breastfeeding. Except for use in amebiasis, studies in pediatric patients are not available; Flagyl ER has no pediatric studies.
