Precautions

Cardizem (diltiazem hydrochloride) is extensively metabolized by the liver and excreted by the kidneys and in bile. As with any drug given over prolonged periods, laboratory parameters of renal and hepatic function should be monitored at regular intervals. The drug should be used with caution in patients with impaired renal or hepatic function.

Dermatological events may be transient and may disappear despite continued use of Cardizem. However, skin eruptions progressing to erythema multiforme and/or exfoliative dermatitis have also been infrequently reported. Should a dermatologic reaction persist, the drug should be discontinued.

Pharmacist Tips

  • Patients controlled on diltiazem alone or in combination with other medications may be switched to Cardizem CD capsules at the nearest equivalent total daily dose.
  • Subsequent titration to higher or lower doses may be necessary and should be initiated as clinically warranted.
  • The incidence of side effects increases as the dose increases with first degree AV block, dizziness, and sinus bradycardia bearing the strongest relationship to dose.
  • Cardizem LA Tablets are an extended-release formulation intended for once-a-day administration.

Diltiazem LA FAQs

Can I take this with food?

Can be taken with or without food.

 

Can I take this if I am pregnant?

There are no well-controlled studies in pregnant women; therefore, use Cardizem in pregnant women only if the potential benefit justifies the potential risk to the fetus.

 

Can I take this while breastfeeding?

Diltiazem is excreted in human milk. One report suggests that concentrations in breast milk may approximate serum levels. If use of Cardizem is deemed essential, an alternative method of infant feeding should be instituted.

 

Can I crush or split the tablet?

The tablet should be swallowed whole and not chewed or crushed.

 

Can I take Cardizem with nitroglycerine?

Sublingual nitroglycerine may be taken as required to abort acute anginal attacks during Cardizem CD (diltiazem hydrochloride) therapy.

 

Can I take Cardizem with other antihypertensives?

Cardizem CD has an additive antihypertensive effect when used with other antihypertensive agents. Therefore, the dosage of Cardizem CD or the concomitant antihypertensives may need to be adjusted when adding one to the other.
