Summary

Amlodipine and nifedipine are both dihydropyridine calcium channel blockers, so taking them together gives duplicate therapy with additive vasodilation. This can cause hypotension, flushing, headache and peripheral edema without a meaningful gain in blood pressure control.

What this interaction means in plain words

Amlodipine-olmesartan-hydrochlorothiazide and Nifedipine can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.

Amlodipine-olmesartan-hydrochlorothiazide belongs to Cardiovascular; Nifedipine belongs to Cardiovascular.

Evidence level: Low

Why it happens

Additive pharmacodynamic vasodilation from two dihydropyridine calcium channel blockers, with a possible minor competition for CYP3A4 metabolism.

What to do

Avoid combining two dihydropyridine calcium channel blockers and keep a single agent. If both have been given, monitor blood pressure and edema and stop one of them.
