Calcium channel blockers: Diltiazem Others (e.g., felodipine, nicardipine, nifedipine, verapamil) ↓ diltiazem * ↓ desacetyl diltiazem * ↓ N-monodesmethyl diltiazem * ↓ calcium channel blocker Diltiazem dose adjustments should be guided by clinical response (refer to the full prescribing information for diltiazem).

When coadministered with efavirenz, dosage adjustment of calcium channels blocker may be needed and should be guided by clinical response (refer to the full prescribing information for the calcium channel blocker).

• Increased amlodipine exposure when coadministered with CYP3A inhibitors Hydrochlorothiazide ( 7.3 ): • Antidiabetic drugs: Dosage adjustment of antidiabetic may be required.

CYP3A Inhibitors: Co-administration of amlodipine with CYP3A inhibitors (moderate and strong) results in increased systemic exposure to amlodipine and may require dose reduction.

Monitor for symptoms of hypotension and edema when amlodipine is co-administered with CYP3A inhibitors to determine the need for dose adjustment.

Blood pressure should be closely monitored when amlodipine is co-administered with CYP3A inducers.

CYP3A Inducers: No information is available on the quantitative effects of CYP3A inducers on amlodipine.
