-
- BRAND NAME (Manufacturer)
-
- Rocaltrol (Roche)
-
- TYPE OF DRUG
-
- Vitamin D analog
-
- INGREDIENT
-
- calcitriol (1.25-dihydroxycholecalciferol)
-
- DOSAGE FORM
-
- Capsules (0.25 mcg and 0.5 mcg)
-
- STORAGE
-
- Calcitriol should be stored at room temperature in a tightly closed,
- light-resistant container.
-
- USES
-
- Vitamin D is essential to bone structure, regulation of blood calcium
- levels, and heart and muscle contraction. Since vitamin D is activated in the
- kidneys, patients with chronic kidney failure are unable to produce enough
- active vitamin D on their own. Calcitriol is one of the active forms of
- vitamin D. This drug is used to treat bone disease and hypocalcemia (low
- blood calcium levels) in dialysis patients.
-
- TREATMENT
-
- Calcitriol can be taken either on an empty stomach or with food or milk
- (as directed by your doctor). The capsules should be swallowed whole; do not
- crush or chew them.
- If you miss a dose of this drug, take the missed dose as soon as
- possible, unless it is almost time for the next dose. In that case, do not
- take the missed dose at all; return to your regular dosing schedule. Do not
- double the next dose.
-
- SIDE EFFECTS
-
- Minor.
-
- None, at the dosages normally prescribed.
-
- Major.
-
- Side effects result from too much medication (vitamin D toxicity). Tell
- your doctor about any side effects that are persistent or particularly
- bothersome. IT IS ESPECIALLY IMPORTANT TO TELL YOUR DOCTOR about appetite
- loss, blurred vision, bone pain, constipation, dry mouth, headache,
- irritability, mental disorders, metallic taste, muscle pain, nausea,
- palpitations, runny nose, increased thirst, increased urination, vomiting,
- weakness, or weight loss.
-
- INTERACTIONS
-
- Calcitriol interacts with several types of medications:
- 1. The dosage of calcitriol may need to be adjusted if anticonvulsant
- medication (phenytoin, phenobarbital, or primidone) is started.
- 2. Cholestyramine, colestipol, and mineral oil can decrease the
- absorption of calcitriol from the gastrointestinal tract.
- 3. Use of magnesium-containing antacids along with calcitriol may cause
- high blood levels of magnesium.
- 4. Calcitriol may lower the effectiveness of verapamil.
- BE SURE TO TELL YOUR DOCTOR about any medications you are currently
- taking, especially any of those listed above.
-
- WARNINGS
-
- * Be sure to tell your doctor about unusual or allergic reactions you
- have had to any medications, especially to calcitriol, calcifediol,
- dihydrotachysterol, ergocalciferol, or vitamin D.
- * Before starting to take this drug, tell your doctor if you have ever
- had heart or blood vessel disease, hypercalcemia (high levels of blood
- calcium), hyperphosphatemia (high levels of blood phosphate), kidney disease,
- vitamin D intoxication, or sarcoidosis.
- * Before taking any over-the-counter (nonprescription) products that
- contain calcium, phosphates, magnesium, or vitamin D, check with your doctor.
- These ingredients can increase the side effects of calcitriol.
- * Be sure to tell your doctor if you are pregnant. Although calcitriol
- appears to be safe during pregnancy in humans, birth defects have been
- reported in the offspring of animals that received large doses during
- pregnancy. Also, tell your doctor if you are breast-feeding an infant.
- Studies have shown that small amounts of calcitriol may pass into breast milk.
