    Can an antihistamine allergy pill be taken with high blood pressure medication?

    Assoc Clinical Professor, St. John’s University

    Most antihistamines are safe to use with medications for high blood pressure. But I would avoid the ones that also contain a decongestant, as these may raise blood pressure.

    I would need to know which medications you take in order to provide a more precise answer. You should talk to your pharmacist before taking any over-the-counter medications, especially if you have high blood pressure.
