    Dehydration Caused by a Medicine

    Dehydration Caused by a Medicine



    Many prescription and nonprescription medicines can cause dehydration. A few examples are:

    • Antihistamines.
    • Blood pressure medicines.
    • Chemotherapy.
    • Diuretics.
    • Laxatives.

    If you think that your dehydration is caused by a medicine:

    • Call the doctor who prescribed the medicine to find out if you should stop taking it or take a different one. An appointment may not be necessary.
    • If you are taking a nonprescription medicine, stop taking it. Call your doctor if you feel you need to continue taking the medicine.
