how long does it take for blood pressure med to enter the body
FROM OUR EXPERTS. Pam, 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. Martin Cane, M.D. VIEW 3 COMMENTS.
