Drug Interactions between L Thyroxine Roche and pramlintide

The timing of meals relative to your oral levothyroxine dose can affect the absorption of the medication. Therefore, levothyroxine 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 levothyroxine 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.

Pramlintide may interact with other medications if taken at the same time. Your other medications should be administered at least 1 hour before or 2 hours after your pramlintide injection. Talk with your doctor before using alcohol while you are using pramlintide. Using pramlintide together with alcohol can lead to hypoglycemia (low blood sugar). Alcohol can cause increased blood sugar due to the calories in alcoholic beverages. You may need a dose adjustment and you may need to check your blood sugar more often.

Using multivitamin with minerals together with levothyroxine may decrease the effects of levothyroxine. You should separate the administration of levothyroxine 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.
