Always inform your doctor or pharmacist about all medications you’re taking, including over-the-counter drugs, vitamins, and herbal supplements, before starting Nizoral. This helps prevent potential drug interactions.
Nizoral (ketoconazole) can interact with several medications, particularly those metabolized by the liver. This includes certain anticoagulants like warfarin, increasing the risk of bleeding. It can also affect the levels of certain medications, potentially reducing their effectiveness or increasing their side effects. Examples include some statins (used to lower cholesterol) and antihistamines.
Specific interactions vary depending on the individual medication and its dosage. Your doctor can assess your situation and advise you on any potential risks or necessary dosage adjustments. Do not stop or alter your medication regimen without consulting your doctor.
Some drugs might increase the risk of liver damage when taken with Nizoral. Your doctor might order regular liver function tests to monitor your health if you are taking other medications that could strain your liver.
If you experience unusual side effects while taking Nizoral, such as unusual bleeding, unexplained fatigue, or jaundice (yellowing of the skin or eyes), contact your doctor immediately.
