Interactions
Be cautious with this combination
Aluminum interacts with VITAMIN D
Aluminum is found in most antacids. Vitamin D can increase how much aluminum the body absorbs. This interaction might be a problem for people with kidney disease. Take vitamin D two hours before, or four hours after antacids.
Calcipotriene (Dovonex) interacts with VITAMIN D
Calcipotriene is a drug that is similar to vitamin D. Taking vitamin D along with calcipotriene (Dovonex) might increase the effects and side effects of calcipotriene (Dovonex). Avoid taking vitamin D supplements if you are taking calcipotriene (Dovonex).
Digoxin (Lanoxin) interacts with VITAMIN D
Vitamin D helps your body absorb calcium. Calcium can affect the heart. Digoxin (Lanoxin) is used to help your heart beat stronger. Taking vitamin D along with digoxin (Lanoxin) might increase the effects of digoxin (Lanoxin) and lead to an irregular heartbeat. If you are taking digoxin (Lanoxin), talk to your doctor before taking vitamin D supplements.
Diltiazem (Cardizem, Dilacor, Tiazac) interacts with VITAMIN D
Vitamin D helps your body absorb calcium. Calcium can affect your heart. Diltiazem (Cardizem, Dilacor, Tiazac) can also affect your heart. Taking large amounts of vitamin D along with diltiazem (Cardizem, Dilacor, Tiazac) might decrease the effectiveness of diltiazem.
Verapamil (Calan, Covera, Isoptin, Verelan) interacts with VITAMIN D
Vitamin D helps your body absorb calcium. Calcium can affect the heart. Verapamil (Calan, Covera, Isoptin, Verelan) can also affect the heart. Do not take large amounts of vitamin D if you are taking verapamil (Calan, Covera, Isoptin, Verelan).
Water pills (Thiazide diuretics) interacts with VITAMIN D
Vitamin D helps your body absorb calcium. Some “water pills” increase the amount of calcium in the body. Taking large amounts of vitamin D along with some “water pills” might cause to be too much calcium in the body. This could cause serious side effects including kidney problems.
Some of these “water pills” include chlorothiazide (Diuril), hydrochlorothiazide (HydroDIURIL, Esidrix), indapamide (Lozol), metolazone (Zaroxolyn), and chlorthalidone (Hygroton).
