Since childhood, we’ve been told that Vitamin D is important for growing strong bones. Between a tall glass of cold milk at dinner and enjoying a few hours of sunshine each day, enabling our bodies to create Vitamin D, getting enough of this important nutrient was simple. However, as we age, it’s no longer simple – and many of your residents will need supplements to stay healthy.
Vitamin D helps the body absorb optimal amounts of calcium to build health. Besides guarding against osteoporosis and osteomalacia, helping your residents avoid life-changing fractures, Vitamin D also helps prevent muscle weakness. Studies also indicate Vitamin D supplements may help prevent or improve:
- Diabetes
- High blood pressure
- Heart disease
- Psoriasis
- Infectious disease
- Multiple sclerosis
- Certain cancers, including colon, prostate and breast
Low levels of Vitamin D have been associated with cognitive decline.
When out in the sunshine, your residents can’t overdose on Vitamin D, as the body regulates its production. Taken as a supplement however, too much Vitamin D can be a problem, causing:
- Confusion and disorientation, ataxia
- Heart rhythm disorders
- Constipation
- Kidney stone
- Kidney damage
- Nausea
- Vomiting
- Poor appetite
- Weight loss
Normal dietary intake for Vitamin D is 160-200 IU each day, but most supplements are 400 IU or more. When Vitamin D is taken in such quantities, interactions may occur that can be dangerous for your residents. Ask your pharmacy to screen for these drugs when your resident takes or is prescribed Vitamin D:
- Aluminum-containing phosphate binders, may contribute to kidney failure
- Anticonvulsants, spurs breakdown of Vitamin D and reduces calcium absorption
- Atorvastatin (Lipitor), may not be properly processed when taken with Vitamin D
- Cholestyramine (Prevalite), reduces absorption of Vitamin D
- Orlisat (Xenical or Alli), reduces absorption of Vitamin D
- Thiazide diuretics, increases risk of hypercalcemia
- Steroids, reduces absorption of calcium
- Stimulant laxatives, reduces absorption of Vitamin D and calcium
Your residents should not take Vitamin D when taking calcipotriene (Dovonex, Sorilux), as it may cause hypercalcemia, too much calcium in the blood.
High doses of Vitamin D should be avoided when your resident is taking:
- Cytochrome P-450 3A4 substrates
- Digoxin (Lanoxin), increasing the chance of fatal heart attack
- Diltiazem (Cardizem, Tiazac and more), causing hypercalcemia and reducing effectiveness of diltiazem, raising blood pressure
- Verapamil (Verelan, Calan SR), causing hypercalcemia and reducing effectiveness of verapamil, raising blood pressure, angina, supra ventricular tachycardia and raising the risk of migraines.
