Drug Interaction Report

Erythromycin may increase the blood levels and effects of cinacalcet. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. Contact your doctor if your condition changes or you experience increased side effects. It is important to tell your doctor about all other medications you use, including vitamins and herbs.

Food decreases the levels of erythromycin in your body. Take erythromycin on an empty stomach at least 30 minutes before or 2 hours after a meal. This will make it easier for your body to absorb the medication. However, some erythromycin products may be taken without regard to meals. Ask your healthcare provider about your particular prescription if you are uncertain of how to take it. Grapefruits and grapefruit juice may increase erythromycin levels but how this may affect you is not known. Do not increase or decrease the amount of grapefruit products in your diet without first talking to your doctor.

Food can enhance the levels of cinacalcet in your body. Cinacalcet should be taken just after eating food. Do not take it on an empty stomach. This will make it easier for your body to absorb the medication. Do not crush, chew, or break the tablets. Swallow them whole.
