Drug Interaction Report

Phenylephrine may interfere with blood glucose control and reduce the effectiveness of pramlintide and other diabetic medications. Monitor your blood sugar levels closely. You may need a dose adjustment of your diabetic medications during and after treatment with phenylephrine. 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.

Both phenylephrine and caffeine can increase blood pressure and heart rate, and combining them may enhance these effects. Talk to your doctor before using these medications, especially if you have a history of high blood pressure or heart disease. 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. Do not stop using any medications without first talking to your doctor.
