Rocaltrol (Calcitriol) Dosage and Side Effects
ROCALTROL is used in the management of Calcium deficiency.
Proper Use of this medication
The effectiveness of ROCALTROL therapy is based on the assumption that each patient is receiving an adequate daily intake of calcium.
To ensure that you receive an adequate daily intake of calcium, your doctor may either prescribe a calcium supplement or instruct appropriate dietary measures. Your doctor may monitor your blood levels of calcium and phosphorus.
Be sure to drink plenty of fluids to maintain good hydration, important during ROCALTROL treatment.
Usual adult dose:
Dosage is based on your medical condition and response to therapy. Your doctor may start you on a low dose and adjust the dose slowly to find the best dose for you. Follow your doctor's directions carefully.
In case of drug overdose, contact a health care practitioner, hospital emergency department or regional Poison Control Centre immediately, even if there are no symptoms.
Take your missed dose as soon as you remember. Skip taking the missed dose if it is almost time for the next scheduled dose. No extra medicine should be taken to make up the missed dose.
