Cardizem CD may cause dizziness. Be cautious with activities requiring alertness (driving, operating machinery) until you know how this medication affects you. Limit alcohol and marijuana use, which can worsen dizziness.

Cardizem CD should only be used when absolutely necessary and only after discussing risks and benefits with your healthcare provider. Consult your healthcare provider before breastfeeding as diltiazem passes into breast milk and may harm your baby.
