- or milk (as directed by your doctor).

- carefully with the dropper provided. The solution can then be swallowed
- directly or mixed with fruit juice, cereal, or other foods.
- If you miss a dose of this medication, 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; just return to your regular dosing schedule. Do not
- double the dose.

-
- The side effects associated with dihydrotachysterol therapy are usually
- the result of too much medication (vitamin D intoxication). Tell your doctor
- about any side effects that are persistent or particularly bothersome. IT IS
- ESPECIALLY IMPORTANT TO TELL YOUR DOCTOR about blurred vision, bone pain,
- constipation, dry mouth, headache, increased thirst, increased urination,
- irritability, loss of appetite, mental disorders, metallic taste in the mouth,
- muscle pain, nausea, palpitations, runny nose, vomiting, weakness, or weight
- loss.
-
- INTERACTIONS
-
- This drug interacts with several other drugs.
- 1. If you are being treated for hypoparathyroidism, concurrent use of
- dihydrotachysterol and thiazide diuretics (water pills) can lead to
- hypercalcemia (high blood calcium levels).
- 2. The effects of this medication may be increased or decreased by
- digoxin, antacids, verapamil, or cholestyramine.
- BE SURE TO TELL YOUR DOCTOR about any medications you are currently
- taking, especially any listed above.
-
- WARNINGS
-
- * Tell your doctor about unusual or allergic reactions you have had to
- any medications, especially to dihydrotachysterol, calcitriol, calcifediol,
- ergocalciferol, or vitamin D.
- * Before starting to take this medication, it is very important that you
- tell your doctor if you now have or if you have ever had heart or blood vessel
- disease, hypercalcemia, hyperphosphatemia, 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 dihydrotachysterol.
- * Dihydrotachysterol is more expensive than vitamin D products, but it is
- often prescribed instead of vitamin D because it is faster-acting and does not
- persist in the body once therapy is stopped.
- * Be sure to tell your doctor if you are pregnant. Although
- dihydrotachysterol has not been studied during pregnancy in humans, birth
- defects have been reported in the offspring of animals that received large
- doses of this medication during pregnancy. Also, tell your doctor if you are
- breast-feeding an infant. It is not known if this drug passes into breast
- milk.
