Edit list (add/remove drugs)

Interactions between your drugs

Moderate

magnesium citrate cholecalciferol

Applies to: Royvac Bowel Evacuant (bisacodyl / magnesium citrate) and Fosamax Plus D (alendronate / cholecalciferol)

Using cholecalciferol together with magnesium citrate can lead to elevated magnesium blood levels, particularly in individuals with reduced kidney function. Symptoms of high magnesium levels may include nausea, vomiting, flushing, drowsiness, dizziness, confusion, muscle weakness, reduced reflexes, low blood pressure, slow heart rate, and impaired breathing. You should seek medical attention if you experience these symptoms. If you are on dialysis and treated with cholecalciferol or other vitamin D medications, you should generally avoid taking products that contain magnesium without first talking to your doctor, as high levels of magnesium over time can lead to bone problems. 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.

Moderate

magnesium citrate alendronate

Applies to: Royvac Bowel Evacuant (bisacodyl / magnesium citrate) and Fosamax Plus D (alendronate / cholecalciferol)

Alendronate and magnesium citrate should not be taken orally at the same time. Products that contain magnesium, aluminum, calcium, iron, and/or other minerals may interfere with the absorption of alendronate into the bloodstream and reduce its effectiveness. You should take magnesium citrate at least 30 minutes after the alendronate dose. Talk to a healthcare professional if you are not sure whether a product contains something that could potentially interact with your medication or if you have questions on how to take this 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

alendronate food

Applies to: Fosamax Plus D (alendronate / cholecalciferol)

Food may reduce the absorption of alendronate, which may lead to lower blood levels of the medication and possibly reduced effectiveness. You should take alendronate first thing in the morning, at least 30 minutes before you eat or drink anything or take any other medication. Take each dose with a full glass (6 to 8 ounces) of water, and use only plain water (not mineral or vitamin water). Do not take alendronate if you cannot sit upright or stand for at least 30 minutes. Because alendronate can cause irritation and ulcer in the stomach or esophagus (the tube that connects your mouth and stomach), you will need to stay upright for at least 30 minutes after taking this medication. Talk to your doctor or pharmacist if you have questions on how to take this 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.
