Drug Interactions between Chewable Calcium with Vitamin D and vadadustat
This report displays the potential drug interactions for the following 2 drugs:
- Chewable Calcium with Vitamin D (calcium/vitamin d)
- vadadustat
Interactions between your drugs
calcium carbonate vadadustat
Applies to: Chewable Calcium with Vitamin D (calcium / vitamin d) and vadadustat
Consumer information for this interaction is not currently available.
ADJUST DOSING INTERVAL: Coadministration of vadadustat with oral products containing multivalent cations such as calcium, magnesium, or aluminum may significantly decrease the bioavailability of vadadustat. The mechanism of this interaction has not been fully described but may involve the formation of an insoluble complex or chelate with multivalent cations that is poorly absorbed from the gastrointestinal tract. According to product labeling, when non-iron-containing phosphate binders were coadministered-administered with vadadustat, the systemic exposure (AUC) and peak plasma concentration (Cmax) decreased by 55% and 52%, respectively.
MANAGEMENT: Vadadustat should be administered at least one hour before, or two hours after the administration of oral non-iron-containing phosphate binders or other medicinal products whose primary component consists of multivalent cations such as calcium, magnesium, or aluminum.
Drug and food interactions
calcium carbonate food
Applies to: Chewable Calcium with Vitamin D (calcium / vitamin d)
Calcium absorption may be increased by taking it with food. However, foods high in oxalic acid (spinach or rhubarb), or phytic acid (bran and whole grains) may decrease calcium absorption. Calcium may be taken with food to increase absorption. Consider spacing calcium administration for at least 2 hours before or after consuming foods high in oxalic acid or phytic acid. Talk to your doctor if you have any questions or concerns. 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.
ergocalciferol food
Applies to: Chewable Calcium with Vitamin D (calcium / vitamin d)
Treatment with ergocalciferol may require you to adjust your dietary intake of foods which contain natural or added calcium, phosphate (organic and inorganic), and vitamin D. Ingesting too much vitamin D or having elevated calcium and/or phosphorus levels in the blood and urine can lead to toxic effects, such as having an irregular heart rhythm, seizures, kidney stones, and eventual calcification of your blood vessels, cornea and/or the soft tissues in your body. Your doctor will monitor the levels of calcium and phosphorus in your blood during treatment with ergocalciferol. Please speak with your healthcare team to determine if you require a specialized diet, particularly if you have reduced kidney function, and to discuss any other questions or concerns you have. You may require additional monitoring or a dose adjustment of ergocalciferol if your diet changes. Fortified foods will state on their labeling how much calcium, phosphate, and/or vitamin D has been added. The National Institutes of Health, Office of Dietary Supplements also provides information on which foods contain calcium, phosphorus, and vitamin D. You should avoid abrupt changes in your dietary calcium intake and seek medical attention if you experience early symptoms of vitamin D intoxication such as weakness, fatigue, headache, drowsiness, vertigo, ringing in the ears, loss of appetite, nausea, vomiting, constipation, dry mouth, metallic taste, muscle pain, bone pain, muscle incoordination, and low muscle tone. Late symptoms may include frequent urination, excessive thirst, weight loss, conjunctivitis ("pink eye"), light sensitivity, runny nose, itching, increased body temperature, and irregular heart rhythm. 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.
vadadustat food
Applies to: vadadustat
Consumer information for this interaction is not currently available.
MONITOR: Smoking and alcohol consumption during therapy with vadadustat may increase the risk of gastrointestinal erosions. Serious erosions, including gastrointestinal bleeding and the need for red blood cell transfusions, have been reported during vadadustat clinical trials. Patients with a history of gastrointestinal erosion, peptic ulcer disease, and current tobacco smokers and alcohol drinkers may be at higher risk of gastrointestinal injury.
MANAGEMENT: Caution is advised if vadadustat is prescribed to current tobacco smokers or alcohol drinkers. Patients should be advised to contact their physician if they develop potential signs and symptoms of gastrointestinal injury such as abdominal pain, hematemesis, trouble swallowing, chest or throat pain, and/or black, tarry stools.
