Drug Interactions between sevelamer and Thyroid Porcine

The timing of meals relative to your oral thyroid desiccated dose can affect the absorption of the medication. Therefore, thyroid desiccated should be taken on a consistent schedule with regard to time of day and relation to meals to avoid large fluctuations in blood levels, which may alter its effects. In addition, absorption of thyroid desiccated may be decreased and/or delayed by foods such as soybean flour, cotton seed meal, walnuts, dietary fiber, calcium, calcium fortified juices and grapefruit or grapefruit juice. These foods should be avoided within several hours of dosing if possible. 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.

Sevelamer may interact with other medications if taken directly with them. As a precaution, other medications that can be affected by changes in blood levels should be administered 1 hour before or 3 hours after sevelamer. This will make it easier for your body to absorb the medication.

Using multivitamin with minerals together with thyroid desiccated may decrease the effects of thyroid desiccated. You should separate the administration of thyroid desiccated and multivitamin with minerals by at least 4 hours. If your doctor does prescribe these medications together, you may need a dose adjustment or special test to safely use both medications. 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.
