Calan Sr Dosage
Dosage of Calan SR depends on the individual and the condition being treated. You should always take medication precisely as your doctor prescribes it. In the treatment of hypertension (high blood pressure), Calan SR may take a period of one week before a patient realizes the full benefits of the drug.
