Thanks for the question.  High blood pressure medications works in different ways and can have an effect in different time periods.  In general you should allow about 2 - 3 weeks to see a full effect from a medication.  This full effect is not only what the medication does, but how your system reacts to the drug and adjusts to the changes. 


I hope this has been helpful.
