Interactions between your drugs

Moderate

rifAMPin lanthanum carbonate

Applies to: rifampin and Fosrenol (lanthanum carbonate)

Lanthanum carbonate and rifAMPin should not be taken orally at the same time. These medications may interfere with each other's absorption into the bloodstream, which may reduce the effects of both medications. To minimize the potential for interaction, avoid taking rifAMPin within 2 hours of taking lanthanum carbonate. Talk to a healthcare professional if you have questions on how to take these or other medications you are prescribed. 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.

Drug and food interactions

Moderate

rifAMPin food

Applies to: rifampin

Food can decrease the levels of rifAMPin in your body. Taking rifAMPin on an empty stomach (at least 30 minutes before or 2 hours after a meal) will make it easier for your body to absorb the medication. Avoid drinking alcohol while taking rifAMPin because alcohol use may increase the risk of damage to your liver. It is important to seek immediate medical care if you experience any severe side effects or symptoms of liver damage such as fever, chills, joint pain or swelling, unusual bleeding or bruising, skin rash, itching, loss of appetite, fatigue, nausea, vomiting, dark colored urine, and/or yellowing of the skin or eyes. 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.
