How many days does it take calcium channel blockers to become fully effective?
A doctor has provided 1 answer
Weeks: Generally speaking, and depending on the specific drug within the class of calcium channel blockers, the answer is roughly 2 to 4 weeks to reach maximum effect, though approximately 80% of the effect is achieved in the first week. Your mileage may vary.
