USES: Diltiazem is a calcium channel blocker. Calcium is involved in blood vessel contraction and in controlling the electrical impulses within the heart. By blocking calcium, diltiazem relaxes and widens blood vessels and can normalize heart rates. Diltiazem injection is used to treat irregular heartbeats.

OTHER USES: This medication may also be used for chest pain (angina) or high blood pressure.

HOW TO USE: This medication is given by vein (slow IV injection or continuous infusion) as directed by the doctor. The patient's blood pressure and heart rhythm (ECG) should be monitored during the administration period. It is generally administered for up to 24 hours or as directed, then therapy is changed to an oral heart drug (antiarrhythmic). The dosage is based on the patient's medical condition and response to the medication. Learn all mixing, dilution and administration/usage instructions in the product package and ask the doctor or pharmacist if you are unclear about any of the information. The liquid should be checked for particles or discoloration. If present, discard the liquid. Make sure needles and medical supplies are stored safely and disposed of properly.
