    I was just wondering how long does it take time for the high blood pressure medication to work?

    The are a several of different classes of BP meds and a many meds within each class.

    Some can take effect within a few hours. Others take longer. Maybe 2-4 weeks.

    Your pharmacist, who knows exactly what meds he is on, might give a more explicit answer.

    If not call your doctors office and asks to speak to his nurse and ask this.

    BTW, lifestyle changes (diet, weight loss, and exercise) typically take 3 or more months to have effect.
